Question

1.       An obstruction in blood flow to the kidneys would result in

	A.	increased erythropoiesis.
	B.	reduced release of renin from the juxtaglomerular cells
	C.	pernicious anemia.
	D.	increased glucose clearance

2. Why do you need parietal cells in your stomach to produce red blood cells?

A.The stomach is needed for nutrition, and you need amino acids and iron to make red blood cells.

B.Iron (Fe2+) is absorbed in the stomach by parietal cells

C.Parietal cells secrete intrinsic factor, which is necessary to absorb vitamin B12 in the small intestine.

D.Parietal cells secrete intrinsic factor that binds Fe2+, allowing it to be absorbed in the small intestine.

3.   What is true about a person with a Rh- blood type?

A.	She is a universal acceptor.
	B.	If she has an Rh-negative baby that baby might have hemolytic disease of the newborn.
	C.	She has anti-Rh antibodies in her plasma.
	D.	She has Rh antigens on her red blood cells.

Answer 1

Ans 1:- a) increases erythropoiesis.

Concept:- Erythropoietin is produced and released into the blood by the kidneys in response to low blood oxygen levels (hypoxemia). EPO is carried to the bone marrow, where it stimulates production of red blood cells.

When blood flow Dec then release of renin also inc. And renal clearence of glucose is decrease because blood flow to kidney is Dec.

Ans2:- C.)Parietal cells secrete intrinsic factor, which is necessary to absorb vitamin B12 in the small intestine.

Concept:- parietal cell help in RBC formation in two ways .

I) relasee intrinsic factor and help in absorption of B12

Ii) relaease HCL which convert Fe3+ to Fe2+.

.	Ans3:C- h) she has anti-Rh antibodies in her plasma. Option c) is more appropriate because Option a) doesn't metion that it is person is AB negative. b) hemolysis ocuure if baby is Rh positive and mother is rh negative. D) rhnegative person have no Rh antigen.
