which feedback mechanism maintains normal count of rbc in blood
Answers
Answer:
An example of a homeostatic mechanism can be illustrated by the body's reaction to a toxin that causes anemia and hypoxia (low tissue oxygen) (Figure 1). The production of red blood cells (erythropoiesis) is controlled primarily by the hormone, erythropoietin.
Answer:
The normal count of RBC in the blood is maintained by the negative feedback loop of homeostasis.
Explanation:
The dynamic equilibrium of the human body is maintained both internally and externally through the process of homeostasis. Any change in the environment changes the conditions of an organism. Adjustments are made to control the changing conditions. These adjustments are known as homeostasis.
Negative feedback loops control the homeostasis in the body. A positive feedback loop destabilizes the body by increasing the changes. Homeostasis brings many processes in the body to equilibrium. One such process is maintaining the normal count of RBC in the blood.
Homeostasis works by receiving the signal from receptors, transferring it to the control systems (central nervous system), and releasing the processed response to effectors. Thus, when the RBC count decreases, the homeostasis mechanism follows to increase the count. And when the RBC count increases more than that of the normal count, the homeostasis mechanism brings the count-down. Special hormones are released to counteract the increasing or decreasing levels of RBC. All of this is done by the negative feedback loop of homeostasis.
