Name: Amy Meagher Student ID: 12148725 Date: 19/02/16 Lab 3: The Effect of Exercise on the Human Cardiovascular System Introduction: During exercise there is an increased demand for energy. The metabolic processes involved in the production of ATP require oxygen. As a result there is an increase in oxygen consumption and an increase in the production of carbon dioxide as a waste product. As the body produces more carbon dioxide there is a greater need to expel this excess carbon dioxide

Name(s): ________________________ Period: _________ Date: ___________ The Respiratory System A healthy respiratory system is crucial to an individual’s overall health, and respiratory distress is often one of the first indicators of a life-threatening illness. The function of the respiratory system is to exchange gases between the external air and the body. The lungs are the primary organ of the respiratory system that performs this function. The lungs take up a large portion of the thoracic cavity

Disease and Evolution The human body has been plagued with diseases since the beginning of time—pathogens like viruses and bacteria have made us privy to Mother Nature. As humans evolve, so do the diseases we are susceptible to. Some diseases that were once rare have become common, others have disappeared and newer, more daunting ones have emerged. Many of these changes have taken place in the wake of important transformations in human civilizations and ecology. It is therefore feasible to propose

It is striated; the fibers (cells) contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers. Skeletal muscle tissue can be made to contract or relax by conscious control (voluntary). The muscular system is responsible for all the movement in the human body. The muscles in the body are attached to bones (roughly 700 of them) this makes up around half of a persons body

The Digestive System is made up of organs that break down food into protein, vitamins, minerals, carbohydrates, and fats, which the body needs for energy, growth, and repair. After the food is chewed and swallowed, it goes down the throat and enters the stomach. It is further broken down by powerful stomach acids. From the stomach the food travels into the small intestine. This is where your food is broken down into nutrients that can enter the bloodstream through tiny hair-like projections. The

Rheumatoid Arthritis (RA) is a musculoskeletal and autoimmune disease, which causes the body’s immune system to target and attack primarily its own joints and joint linings (Brodwin, Tellez, & Brodwin, 2009, p. 124). Since RA is a systematic disease, it affects the body as a whole, and is not limited only to joints. The inflammation and pain can spread from the joints, into the cartilage, connective tissue, and ultimately into adjacent organs (Cush, Kavanaugh, & Stein, 2005, p. 323). After the initial

Muscular System The muscular system is made up muscles, joints, tendons, bones, ligaments and connective tissue that help to support the body’s internal organs. They work together to perform a variety of functions. These include; stability, posture, motion, heat, circulation and digestion within the body. Essentially the muscular system provides power for movement of all body parts. It is the muscles within our body which provide us with movement via contractions and without this vital system life

Abstract Alzheimer's disease involves cognitive disorders and problems with abstract reasoning in older people mostly. Alzheimer's disease has many behavioural and emotional characteristics which affects the victims of Alzheimer, as well as their families and those who care for them. The exact cause of Alzheimer is still not clear to us, not even after all these years of research. Till now, all we know is that a small proportion of Alzheimer’s disease is inherited, many scientist believe that
