a. Individuals who have severe allergies (for example, to bee stings or peanut butter) often carry an EpiPen. It is a self-injecting device that delivers a single dose of 0.3 mg of epinephrine. Epinephrine (more familiarly known as adrenaline) is a hormone that responds to stress by increasing heart rate and blood pressure and boosting the supply of oxygen and energy-giving glucose to the blood and brain. Suppose the body loses 21% of the Epinephrine every hour. Find the amount of Epinephrine left in the body after 3 hours.

Briefly describe endocrine disruptors, how they act, toxicity caused and the effects they bring about with two examples

X A lack of insulin production by the pancreas leads to various symptoms such as excess urination, thirst, lack of energy and fatigue. The direct cause of a lack of energy and fatigue is that body cells burn glucose supplies too rapidly the kidneys excrete too much of glucose there are inadequate glucose levels in the blood. Obody cells do not absorb glucose from the blood. None of the answers listed are correct.

Define frailty and possible endocrine-immune system involvement.

Give examples of two histamine antagonists that have very different tissue specificities and functions.

Describe the mechanism, how epinephrine stops anaphylaxis. Also, determine the consequences if too much epinephrine is administered into the body.

A.

Give five effects atropine will have on the human body.

Predict the effect of an overdose of insulin on brain function in a normal person.

The maintenance of homeostasis is of major importance to all organ systems in the body and the overall survival of the individual. Explain how homeostasis is the maintenance of a dynamic range of environmental qualities rather than holding the internal environment at a set point. What would be wrong with a set point (say for body temperature) rather than a working range of temperatures? The endocrine system is closely tied to homeostasis functioning. Give two examples of hormones (including their glands of origin and action) that play major roles in homeostatic processes in the body. What happens if these hormones are disrupted in their actions? Also, look at how we adapt to survival in the outside world. Discuss how maintaining homeostasis gives us greater freedom of activity from dependence upon changes in the external environment. What happens during extremes that force our bodies out of homeostatic bounds? Give specific examples. Why is the maintenance of homeostasis especially…
