...2.3 Explain how the body coordinates its internal activities • Homeostasis • Principle of feedback loops For the human body to function, cells within the body have to work and function correctly. Tissues, cells and organs all have different jobs with very different functions. The cells must have an internal environment which has to be stable to suit them for them. This enables survival for example things necessary are oxygen, nutrients or the removal of waste products. This ensures the human body is healthy and is able to function. This process where the body can control this internal environment no matter what is going out in the external environment this is known as homeostasis. Homeostasis involves the stability of equilibrium within a cell or within the human body. Homeostasis is maintaining a constant environment within the body for example homeostasis is very important making sure our bodies have the correct levels of oxygen, carbon dioxide, water, and maintain a correct body temperature. Homeostasis is vital to ensure all living things survival, keeping a stable and balanced internal environment which can constantly change within and out of the cell; this is known as homeostatic regulation. Homeostasis can be recognised as a dynamic equilibrium or steady state due to within a cell every mechanism that is kept alive is a...

...body systems. Learners will be able to gain an overview of the organisation of the human body before looking at how body systems work together to provide energy for the body. Learners will have the opportunity to investigate how homeostatic mechanisms operate in the body. Unit introduction This unit introduces core knowledge of cellular structure and function, and the organisation of the body as a whole, and then builds on this to develop a more detailed knowledge of the fine anatomy and physiology of the systems involved in energy metabolism. Learners will examine the homeostatic mechanisms involved in regulating these systems to maintain health. Learners will be given the opportunity to undertake practical activities which will require them to take measurements of the cardio-vascular system, the respiratory system and of body temperature, using noninvasive techniques to investigate normal responses to routine variations in body functioning. This unit provides the core understanding of human physiology that underpins the study of the specialist physiology units within this programme. The unit also provides an overview of body functioning that is valuable for anyone working or intending to work in a field relating to health and social care.

...function a.) Describe how agonists and antagonists act to disrupt normal hormone function. Use examples and describe the resulting disease states that may result Humans are exposed to thousands of chemicals during their lifetime, through the air, food, and water. A significant number of these chemicals can be toxic since they can disrupt the endocrine system. Over the past decade, the list of chemicals with endocrine disrupting activity has dramatically increased. Natural hormones are themselves agonists and, in many cases, more than one distinct hormone binds to the same receptor. For a given receptor, different agonists can have dramatically different potencies. Antagonists are molecules that bind the receptor and block binding of the agonist, but fail to trigger intracellular signalling events. Receptors can be activated or inactivated by either endogenous (such as hormones and neurotransmitters) or exogenous (such as drugs) agonists and antagonists, resulting in the stimulation or inhibition of a biological response. A physiological agonist is a substance that creates the same bodily responses but does not bind to the same receptor. Bisphenol A (BPA) is an industrial compound and a well-known endocrine-disrupting chemical with estrogenic activity. The widespread exposure of individuals to BPA is suspected to affect a variety of physiological functions, including reproduction, development, and metabolism. Many known obesogens are Endocrine disrupting chemicals (EDCs)...

...This assignment is based upon stress, the bio-psychosocial approach on how stress can affect health, well-being and the maintenance of homeostasis. There are many definitions of stress but the majority of definitions put emphasis on the relationship between the individual and the environment. This is called the bio-psychosocial approach. When treating patients the Practitioner should take a more holistic approach when determining the type of treatment that is required, this would include taking into account the patients lifestyle, environment and social support. The World Health Organisation states that ‘Health is a state of complete physical, mental and social well being and not merely the absence of disease or infirmity’. (WHO 1948). Stress can be defined as any type of change that causes physical, emotional or psychological strain. However, there are many types of stress and not all types of stress are harmful or negative. One theory is that stress is the result of a persons appraisal process. The assessment of whether personal resources are sufficient to meet the demands of the environment. Stress has been identified as being the individuals ability to adapt to the environment (Lazarus and Folkman 1984; Lazarus and Launer 1978; Pervin 1989). There are two types of stress response which Lazarus (1966) made a distinction between, these are psychological and physiological stress. Lazarus stated that physiological stress is a response to a physical damage already incurred...

Explain the functions of each system of the body: digestive, cardiovascular (respiratory and circulatory), immune, skeletal/muscular, endocrine, reproductive, and nervous. Digestive breaks down food for enery. 2. Compare and contrast how positive and negative feedback mechanisms are used to maintain homeostasis. Use these concepts to describe: * The maintenance of blood glucose levels When there is too much glucose in the body, insulin us used to bring it back to the normal level. This uses negative feedback because it is bringing the blood glucose levels back to normal. * The release of platelets to form blood clots. The first platelets will bind to the area of the wound and will release a signal that recruits more platelets tot come to the site. This is an example of positive feedback- the output enhances or exaggerates the original stimulus. 3. What does it mean if an organism is an ectotherm? Endotherm? Give an example of each. An ectotherm does not regulate its own temp and depend on the envirmental temp. and endortherm can control its temp. 4. Herbivorous mammals tend to have extremely long digestive systems, especially the intestines; omnivores have intermediate length intestines; and carnivores have extremely short intestines. What might be a logical explanation for this pattern? It takes longer to digest plants because of the cell wall. Thus there needs to be a longer digestive tracks...

...regulated by… • Homeostasis: steady state of equilibrium within bodily systems. A system is returned to a resting level through motivational states that energise and direct homeostasis-restoring behaviours. ! • Thus, homeostatic systems include several features: 1. Set Point: biologically optimal level the system strives to maintain. 2. Feedback mechanisms: provide information regarding the state of the system with respect to variables being regulated. 3. Corrective mechanisms: restore the system to its set point when needed. Physiological needs describe a deficient biological condition. Occur with tissue and bloodstream deficits, as from water loss, nutrient deprivation or physical injury. ➡ If water loss occurs below an optimal homeostatic level (around 2%) this creates the physiological need that underlies thirst. defined as • THIRST iswater deficit.a consciously experienced motivational state (drive) that readies the body to perform behaviours needed to replenish ➡ So drive is a psychological (not biological) term.

...Human Brain The anatomy of the brain is complex due its intricate structure and function. This amazing organ acts as a control center by receiving, interpreting, and directing sensory information throughout the body. There are three major divisions of the brain. They are the forebrain, the midbrain, and the hindbrain. Anatomy of the Brain: Brain Divisions The forebrain is responsible for a variety of functions including receiving and processing sensory information, thinking, perceiving, producing and understanding language, and controlling motor function. There are two major divisions of forebrain: the diencephalon and the telencephalon. The diencephalon contains structures such as the thalamus and hypothalamus which are responsible for such functions as motor control, relaying sensory information, and controlling autonomic functions. The telencephalon contains the largest part of the brain, the cerebral cortex. Most of the actual information processing in the brain takes place in the cerebral cortex. The midbrain and the hindbrain together make up the brainstem. The midbrain is the portion of the brainstem that connects the hindbrain and the forebrain. This region of the brain is involved in auditory and visual responses as well as motor function. The hindbrain extends from the spinal cord and is composed of the metencephalon and myelencephalon. The metencephalon contains structures such as the pons and cerebellum. These regions assists in maintaining balance...

...from the blood to the inside of the cells. The body cannot use the insulin for energy if it cannot get into the cells. Diabetes occurs when the body has too much blood glucose due to either the pancreas does not produce enough insulin or the body cannot effectively use the insulin produced. In type 2 diabetes (formerly called non-insulin-dependent diabetes or adult-onset diabetes), the pancreas continues to produce insulin, sometimes even at higher-than-normal levels. However, the body develops resistance to the effects of insulin, so there is not enough insulin to meet the body's needs. Diabetes Mellitus is a chronic health disorder; it means that the condition lasts for many years. Diabetes can cause serious health problems. It is an endocrine disorder causing various metabolic changes in the body leading to severe complications such as damage to the eyes, kidneys, nerves, heart and blood vessels. The causes of diabetes mellitus are unclear. Both heredity and environment may be involved. Studies have shown that certain genetic factors may be responsible for diabetes. Genes are chemical units found in all cells, which tell cells what functions they should perform. Genes are passed down from parents to children. If parents carry a gene for diabetes, they may pass that gene onto their children. It not treated properly; type 2 diabetes can cause kidney damage, poor circulation, and numbness in the feet.

...Bodily Systems and the Spatial-Functional Structure of the Human Body Barry Smith, PhD1,2, Igor Papakin1, Katherine Munn1 1Institute for Formal Ontology and Medical Information Science Faculty of Medicine, University of Leipzig, Leipzig, Germany 2Department of Philosophy, University at Buffalo, Buffalo, NY, USA Abstract. The human body as conceived by medical science is a system made of systems. The body is divided into bodily systems proper, such as the endocrine and circulatory systems. These are subdivded into many subsystems at a variety of levels whereby all systems and subsystems engage in massive causal interaction with other systems and subsystems. In this essay we offer an explicit definition of bodily system, and explicit means for understanding these causal interactions. Whereas informality is acceptable in documentation created for human beings, it falls short of what is needed for computer representations. In our analysis we will define bodily system, and will take some first steps toward understanding the causal relationships bodily systems have with their subsystems. 1. Introduction Ontology plays an increasingly significant role in work on terminology and knowledge management systems in the domain of biomedical informatics, and we hold that it will play an essential role in biomedical research of the future. The term ‘ontology’ must, however, be understood in the right way [1]. The dominant paradigm might be referred to as ‘applications...

...Treating Diabetes Mellitus Type II Treating Diabetes Mellitus Type II Type II diabetes (T2D) is a metabolic disorder characterized by chronically elevated blood glucose levels. It characteristically results from a surplus caloric intake, as compared to energy consumption, combined with inadequate insulin secretion, due to dysfunction of the insulin-secreting pancreatic beta cells (Pfeiffer & Klein, 2014). Type II diabetes has reached pandemic levels, despite efforts to slow its progression. In a society where healthcare is ever-changing, primary care physicians, along with advanced practitioners are now treating this disease more readily, as compared to specialist and endocrinologist in the past. As with many disease processes, there are several options when choosing a treatment plan for type II diabetes. Combining knowledge and evidence-based research, the practitioner will be able to establish an individualized treatment plan for treating type II diabetes mellitus. Pathophysiology Type II diabetes is a very complex, non-communicable disease that effects more than 370 million people throughout the world. The symptoms of this disease can vary from patient to patient. Without intense and concentrated efforts to address the pathogenesis and treatment of this syndrome, the destructive macrovascular and microvascular outcomes of type II diabetes will remain a major problem for years to come (Kahn, Cooper, & Del Prato, 2014). In T2D plasma insulin levels may be low,...
