...M2: Explain the probable homeostatic responses to changes in the internal environment during exercise. D2: Explain the importance of homeostasis in maintaining the healthy functioning of the body. Homeostasis is highly important as many processes going on in our body are based on this phenomenon. Homeostasis processes every day in our body are diffusion, osmosis, active transport etc. Diffusion means movement of solute molecules from a section of its high concentration to the low concentration region. Osmosis is movement of water from a mixed solution to a concentrated solution through a semi-permeable membrane. Homeostasis is the balance or equilibrium. How your body works to maintain equilibrium is reflected in how your vital signs vary with activity. Heart rate, blood pressure and respiration are lowest during periods of rest and sleep. During exercise, blood pressure, pulse and respiration increase to meet the increased demand for oxygen and nutrients by your musculoskeletal system. The adjustment of vital signs to match your body's level of physical activity is an example of homeostasis in action. Homeostasis is the regulation and maintaining of the body's internal environment. These levels need to be controlled so that the body can function properly, for example enzymes work at optimum temperatures/ pH levels around the body, so in order to function the internal environments must be controlled. Levels which are controlled tend to oscillate between high and low about...

...Homeostasis Day to day, we are exposed to many external stressors in the environment. These might be exercise, stress, anxiety, weather, changes of location. To survive these changes, our internal body is able to intelligently adapt. The maintenance of a constant and steady internal environment is controlled by homeostasis. P5 Explain the concept of homeostasis Describe homeostasis. For this, you must cover: * Definition of homeostasis * Internal environment- THREE systems that need to be regulated (water levels or waste products; body temperature; blood glucose) * Concept of negative feedback as a regulatory mechanism Websites: http://www.s-cool.co.uk/a-level/biology/homeostasis http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/homeo/homeostasis1.shtml M2 discuss the probable homeostatic responses to changes in the internal environment during exercise Identify and describe the homeostatic mechanisms and how they regulate a steady internal environment during exercise. Summarise - you do not have to explain this in lots of detail. You must cover: * heart rate and how this is controlled by the autonomic nervous system (sympathetic and parasympathetic nerve system). The effects of increased body temperature and adrenaline on heart rate * breathing rate and how this is controlled by the respiratory centre, diaphragm and intercostal muscles * body temperature and how this is controlled by loss of heat by the body...

...the anatomy and physiology of human 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. Learning outcomes On completion of this unit a learner should: 1. Know the organisation of the human body 2. Understand the functioning of the body systems associated with energy metabolism ...

...drinking and sleeping are 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. Conscious manifestation of an underlying biological need that has motivational properties (to energise and direct behaviour). ➡ How does thurst arise? Water lies inside (intracellular fluid contributes 40% body weight) and outside (extracellular fluid contributes 20% body weight) cells. ! We may distinguish between osmometric (intracellular) and volumetric (extracellular) thirst. ➡ How does our body know when to stop drinking? negative feedback...

...The Importance of the Nephron in Kidneys All living organisms require a source of energy, usually in the form of food, to satisfy the cellular demands of the body and ultimately to sustain life. Thus, the nutrients that are consumed by organisms are broken down by various processes within organs, tissues, and cells, in order for important molecules, like minerals, vitamins, proteins, and carbohydrates, to be taken up and distributed around the body. The molecules not needed by the body or ends up as excess in the blood, is discarded as waste products; the system that is responsible for filtering our body, or rather our blood from these waste products, is known as the urinary system. The urinary system consists of organs in the body specific to filtering out excessive fluid and other substances from the bloodstream. This system works together with other organs like the lungs, skin, and intestines, all of which help with the process of eliminating wastes, and regulate the amount of chemicals and water floating in a person’s body (Campbell, “Excretory System”). In addition, these accessory systems to the urinary system ultimately help the body maintain pressure, volume, and composition of the blood (Campbell, “Excretory”). Along with electrolytes, uric acid, and glucose, the urinary system also removes a protein essential for breaking down proteins in the body which is called urea. Urea, together with water and other waste products, forms the liquid that is excreted from organisms...

Members: Adriano, Gaylord Dabac, Aira Camille Enverga, Rika Giana Gabay, Niña Grace Lestor, Vincent Khalid Licopit. Nicholle Group IV/ BSN 4-C Nursing Research 2 CHAPTER 1 The Problem and Its Background Introduction Growing old is inevitable. It is part of life and it happens to everyone. Nobody can prevent himself/herself from getting old. The aging process entails new challenges such as failing health, loss of memory, graying hair, and life transitions like retirement, family relationships, lost career, cessation of social activities and maintaining ones standard of living. Nowadays, our elder relatives are still supporting their sons and daughter in caring for their grandchildren. This kind of situation is commonly seen in our country. Our elderly supports not only in caring but also financially. They tend to divide their budget from their pension to help their relatives. Presently, globalization and modernization have tremendous impact on the family system. The exodus of working age adults to jobs abroad has established a pattern of the older persons assuming surrogate parental ones. To them is entrusted the responsibility of providing parental care over their grandchildren whose parents have left for more lucrative jobs overseas. This poses undue strain on the psychological...

...nursing students is their Learning Experience. The related learning experience is a series of planned activities in the community that would prepare students technically and professionally should they decide to pursue higher education in the health profession. Specifically, in a selected College of nursing, BSN students spend a maximum of 24 hours a week for their duty wherein they engage in activities such as nurse-patient interaction, nursing procedures, construction of Concept Map, Nursing Care Plan and Drug Study, individual conference with their clinical instructors, and ward class. According to Kaplan (1993), the burnout behaviors of students are characterized by reduction in their performance. Students were found to be maintaining a façade of high achieving while succumbing to physical illness and emotional stress. The physical...

...Motivation is the driving force that causes the flux from desire to will in life. For example, hunger is a motivation that elicits a desire to eat. Motivation has been shown to have roots in physiological, behavioral, cognitive, and social areas. Motivation may be rooted in a basic impulse to optimize well-being, minimize physical pain and maximize pleasure. It can also originate from specific physical needs such as eating, sleeping or resting, and sex. Motivation is an inner drive to behave or act in a certain manner. These inner conditions such as wishes, desires and goals, activate to move in a particular direction in behavior.

...Marriage Guidance – Summary MGG201W MGG201W – Marriage Guidance – facilitative couples counselling Theme ONE – Understanding couples Intimacy involves: love, affection and caring, deep attachment to another person. The TRIPOD of couple relationships An intimate relationship consists of three factors that form a tripod on which the relationship rests. 1. Passionate attraction (PA) 2. Mutual expectations (ME) 3. Personal intentions (PI) Passionate attractions (PA) → Individual experiences intensely pleasurable sensations when thinking about or being with a new partner. → Blushing, trembling, breathlessness, high sexual desire → Referred to as infatuation = passing love “a foolish and unreasoning love’ → Infatuation is not a realistic / accurate appraisal of the relationship / idealisation → Negative / flaws in the idealised beloved may be intellectually recognised, but disregarded as endearingly special. Person chooses to ignore the negatives → Normal phase in the process of relationships → Infatuation can lead to a lasting relationship – but it mostly fades away and relationship based on infatuation alone will fail. Love → Involves physical attraction - deeper → Love encompasses PA, ME and PI → People rely mostly on life experiences to guide them to their own unique way of demonstrating love. → Eric Fromm “love is active concern for the life and growth of the person we love” → Love is deep, unselfish, caring, deep respect Hauck’s basic principles about love • It is not just...

...Motivation is a theoretical construct, used to explain behavior. It is the scientific word used to represent the reasons for our actions, our desires, our needs, etc. Motives are hypothetical constructs, used to explain why people do what they do. A motive is what prompts a person to act in a certain way or at least develop an inclination for specific behavior.[1] For example, when someone eats food to satisfy the need of hunger, or when a student does his/her work in school because they want a good grade. Both show a similar connection between what we do and why we do it. According to Maehr and Meyer, "Motivation is a word that is part of the popular culture as few other psychological concepts are".[2] Wikipedia readers will have a motive (or motives) for reading an article, even if such motives are complex and difficult to pinpoint. At the other end of the range of complexity, hunger is frequently the motive for seeking out and consuming food.Types of theories and models[edit] Motivation theories can be classified on a number of basis. Natural vs. Rational based on whether the underlying theory of human Cognition is based on natural forces (drives, needs, desires) or some kind of rationality (instrumentality, meaningfulness, self-identity). Content vs. Process based on whether the focus is on the content ("what") motivates vs process ("how") motivation takes place. Monist and pluralistic motivational theories[edit] A class of theories about why people do things seeks...
