NR507 Week2 Anemia | Questions with 100% Verified
Answers | Latest Update 2026/2027
Question: What is the primary function of red blood cells?
Answer: To transport oxygen from the lungs to the body's tissues and return carbon dioxide
from
the tissues to the lungs.
Question: Why are red blood cells essential for the body?
Answer: They are critical for cellular metabolism and respiratory gas exchange.
Question: Where are red blood cells produced?
Answer: In the bone marrow.
Question: What is the process of red blood cell production called?
Answer: Erythropoiesis.
Question: What hormone regulates erythropoiesis?
Answer: Erythropoietin (EPO).
Question: When is erythropoietin released in greater amounts?
Answer: When oxygen levels in the body are low.
Question: What is the purpose of erythropoietin?
Answer: To stimulate the bone marrow to produce more red blood cells and maintain tissue
oxygenation.
Question: What is anemia?
Answer: A condition in which there is a deficit of red blood cells or hemoglobin, leading to
reduced oxygen delivery to tissues.
Question: What happens to tissue oxygenation in anemia?
Answer: Tissue oxygenation decreases because less oxygen is delivered to the body's cells.
Question: What are the four major causes of anemia?
Answer: Blood loss, hemodilution, inadequate red blood cell production, and increased red
blood cell destruction.
Question: How does blood loss cause anemia?
Answer: By reducing the total number of circulating red blood cells.
Question: How does hemodilution cause anemia?
Answer: By increasing plasma volume, which dilutes the concentration of red blood cells.
