network of vessels and organs that is in charge of the hormones‚ flow of blood‚ nutrients‚ and oxygen and other gases to and from the cells. Without the circulatory system‚ the body could not function properly. The circulatory system maintains homeostasis in a number of ways. In times of need the blood vessels come together to direct the blood to wherever it is required in the body. Also‚ the circulatory system gets rid of all waste products away from areas where they could build up enough to be

nervous system plays an important role in the normal functioning of the human organism‚ because it plays an important role of survival; it makes possible the kind of learning humans need to cope with changes in their environment. 4. It maintains homeostasis by controlling and regulating the other parts of the body. Like the functioning of muscles‚ movement‚ and brain functioning as well. 5. The nervous system is made of primarily two different kinds of cells in

Evolution is a process of gradual change over time in both body and corresponding behaviour (Open University Glossary‚ 2013). The evolution of animals’ and humans’ nervous systems is a necessary process to maximise the chances of survival. Neuronal and behavioural changes are closely linked to the environment surrounding animals and humans‚ as well as to their lifestyles. This essay will present some evidence that the nervous system of animals and humans have evolved as to maximize survival‚ by looking

breakdown in the liver. Both of these nitrogen products can be poisonous to the body and must be removed in the urine. Nephron The functional and structural unit of the kidney is the nephron. The nephron produces urine and is the primary unit of homeostasis in the body. It is essentially a long tubule with a series of associated blood vessels. The upper end of the tubule is an enlarged cuplike structure called the Bowman’s capsule. Below the Bowman’s capsule‚ the tubule coils to form the proximal tubule

Homeostatic Imbalance Regina Gilman A&P II May 6‚ 2015 To function properly the body has systems to maintain homeostasis‚ the maintenance of a steady internal state‚ despite changes in external or internal conditions. Homeostasis is maintained through negative feedback and positive feedback systems. Homeostasis enables body systems of a human being to function as expected because of proper temperature regulation. When someone has to be placed on dialysis their body goes through a process

amount consumed in a specific time was measured and compared to the rates at a colder temperature. Just as expected‚ oxygen was consumed more rapidly at a lower temperature. This would lead to the conclusion that more oxygen is required to maintain homeostasis in a system. Introduction Metabolic rate is a measurement of energy used by an animal within a specific period of time. This can be measured in a number of ways: recording an animal’s heat loss with a calorimeter‚ determining the amount of

Marian body went through the process of homeostasis from experiencing hyperthermia. “Homeostasis is a state of body equilibrium or stable internal environment of the body.”(Marieb 8) Homeostasis protects the body by allowing it to adapt to the environment. Marian homeostasis tried to cool the body but failed. Though Marian was lucky her daughter found her in time. When a heat stroke occurs the body’s homeostasis shuts down where the temperature can reach high enough to cause
