Homeostasis

Using the South University Online Library or the Internet, research about homeostasis.

Based on your research and understanding, provide your response to the following tasks:

*Analyze the feedback mechanisms that maintain homeostasis, and what happens when these systems do not function appropriately.

*Provide two specific examples for each.

*Provide the organizational levels in order, beginning at the atom.

*Then, analyze how each level relates to specific functions and to each other.

*Evaluate metabolism, anabolism, and catabolism.

*Then, distinguish them by providing an example for each of these and the end result for that reaction.

*Analyze and define internal and external respiration in terms of physiology and anatomy.

Please answer all questions....

Solution

Q. Analyze the feedback mechanisms that maintain homeostasis, and what happens when these systems do not function appropriately.

Ans. There are two types of feedback mechanisms in body that maintain homeostasis one is Negative Feedback and another is Positive Feedback ( just opposite to Negative feedback).

Negative feedback:

Almost all homeostatic control mechanisms are negative feedback mechanisms. These mechanisms change the variable to its original state.

Home thermostat (heating system) is one of an example. that work on autocut/autostart principle to maintain set environment. The control of blood sugar (glucose) by insulin is another good example of a negative feedback mechanism.

Positive Feedback Mechanism: this is just opposit to previous one. Blood clotting is one of example of a positive feedback mechanism.

If the system does not work properly we can not emagine of life without external saurces and medical aid everytime. our nerves system will not work, our body will not stable.
