Homeostasis

Homeostasis Homeostasis is responding to changes in the conditions of the external environment and the internal environment. Homeostasis works to elevate the organisms internal environment indoors tolerance limits; the range of conditions where the bodys processes be able to function at a level that would birth life to continue in that organism. The respiratory, cardiovascular, and muscular systems be solely told controlled by homeostasis. Changes in the activities of the cardiovascular system argon more than a result of changes in the activities of other systems. The heart rate, cardiac output, peripheral resistance and blood pressure respond to diametral degrees of somatic exertion, and sometimes our level of activity is affected by environmental factors. The heart rate slows and cardiac output give when demands on incarnate systems are less are in a secure and non-threatening environment. When demands are high on bodily systems, the heart rate is high. Breath ing is essential to life: it allows nuclear number 8 to be taken in, carbon dioxide to be given off, and blood to be regulated. Processing food within cells in order to stimulate the energy needed for a wide range of cellular activities is dependent on a continuous supply of oxygen to the cells. The respiratory system takes in oxygen and excretes carbon dioxide.

Homeostasis allows the respiratory system to take in oxygen in some(prenominal) different situations where the breathing rate is unsteady or unusual. Muscular activity requires a source of energy. When passs are working aerobically, there are several products; waken, carbon dioxide, and water. The heat produced by active musc les helps to assert body temperature, so mu! scle is contributing to heat homeostasis. However, if much heat is being produced than is needed, as for example during vigorous exercise, the bare heat has to be garbled from the body to prevent a harmful rise in body...
