usually caused by the lens not being round enough or the eyeball is too short‚ with this close objects are blurred. 5. Describe the feedback loop responsible for regulating blood glucose levels. What illness results if this system no longer functions properly? Blood glucose levels are regulated by negative feedback loop in order to keep it in homeostasis and the levels are monitored by the pancreases islets of langerhans. Diabetes occurs if this doesnt properly work.

concept: Homeostatic mechanisms use negative feedback to regulate a normal condition. Whether a positive or negative change from the normal condition occurs‚ the body counteracts it to restore the norm. [ Refer to figure 1 in annex below ] Osmoregulation is the process where the body regulates a constant blood water potential by controlling its water and solute concentrations. [ Refer to figure 2.1 and 2.2 in annex below ] Daily life application: Homeostasis is crucial to an organism as it allows

Provide examples to support your thinking. • The body is constantly changing‚ no matter what age. It has to maintain homeostasis or balance at all times or if illness/death occurs. If your body is weakened‚ it then becomes harder to maintain this state. So if someone gets sick or deathly

What is responsible for raising Jim’s heart and respiratory rate and stimulating sweat just before the race? Homeostasis is the cause. Jim is nervous but he is making his body be calm so he doesn’t psych himself out. His nervous system sends signals to his heart. His respiratory rate increases. Since his heart is beating faster and respiratory rate increased this caused him to breathe more rapidly and his

they are admitted to the intensive care unit (ICU) to receive the level of care they need. Hypothermia causes alterations of the body’s core temperature activating not only physiological but behavioral responses as well in an effort to maintain homeostasis (34). Upon receiving an uninterrupted sensation of cold‚ the skin’s motor neurons are stimulated which creates the shiver response within the muscles of the body. This response is an effort to generate heat which is stated to begin within the trunk
