Homework Answers
Constriction of arteries supplying the blood to the kidneys is called, "hypoxia." The process of producing red blood cells is called, “erythropoiesis.” It is stimulated by the erythropoietin (EPO), which is a hormone synthesized by the kidney. EPO stimulate the stem cells present in the bone marrow thus, initiating the process of erythropoiesis.
Hypoxia in the kidneys trigger the increased release of EPO, which results in increased RBC production. Dehydration and heart disease are the two other conditions that cause a low oxygen supply to the kidneys.

A Schematic Model of Red Blood Cell Production The following problem deals with the number of red blood cells (RBCs) circulating in the blood. Here we will present it as a discrete problem to be modeled by differ- ence equations, though a different approach is clearly possible. In the circulatory system, the red blood cells (RBCs) are constantly being de stroyed and replaced. Since these cells carry oxygen throughout the body, their num. ber must be maintained at some fixed...

Need help in calculating the first answer!
Red Blood Cells
Charge of Cell #1 = -1.8 x 10-12 C
Charge of Cell #2 = -3.1 x 10-12 C
Diameter = 6.8 x 10-6 m
Two red blood cells each have a mass of 7.50 x 10-14 kg and carry a negative charge spread uniformly over their surfaces The repulsion arising from the excess charge prevents the cells from clumping together. Once cell carries -1.80 pC of charge and the other...
