Question
Chapter 34.3, Problem 6MI
Summary Introduction
To determine:
The role of excretory system in controlling homeostasis.
Introduction:
Urinary system or the excretory system is the organ system present in mammals and other animals. The main function of this system is to get rid of the toxic chemicals, especially nitrogenous waster produced by the body in various biochemical processes. The kidney is the chief organ of the excretory system.
Expert Solution & Answer
Explanation of Solution
The role of excretory system in maintaining homeostasis is as follows:
- Excretory system maintains the fluid and electrolyte balance in blood by excreting and reabsorption of water an electrolytes.
- It secretes erythropoietin, which is a hormone responsible for triggering RBCs production and maintain the level of red blood cells.
- Kidney is a part of RAAS pathway, and secretes renin that helps in controlling a proper blood pressure.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
