Questions & Answers
Question 20: What triggers the production of new red blood cells in the body?
The answer: An erythropoietic stimulus or trigger is needed to initiate the production of new red cells.
Question 21: Why is hemoglobin essential for red blood cells?
The answer: Hemoglobin is essential for transporting oxygen in the bloodstream.
Question 22: What is the role of blast cells in blood cell development?
The answer: Blast cells are precursor cells involved in blood cell development.
Question 23: How do mature red blood cells contribute to oxygen transport?
The answer: Mature red blood cells carry oxygen by binding it to hemoglobin.
Question 24: Where does erythropoiesis primarily occur in the body?
The answer: Erythropoiesis primarily occurs in the bone marrow.
Question 25: What is the primary role of platelets in the bloodstream?
The answer: Platelets play a vital role in blood clotting.
Question 26: Define "leucocytes" in the context of blood cells.
The answer: Leucocytes are white blood cells that play a role in the immune system.
Question 27: Which cells give rise to all formed elements of the blood?
The answer: Common ancestor stem cells in the bone marrow give rise to all formed blood elements.
Question 28: What triggers the release of erythropoietin (EPO) in the body?
The answer: Low oxygen levels in the blood trigger the release of erythropoietin.
Question 29: Which cells are essential for maintaining the balance of red blood cell production?
The answer: An erythropoietic stimulus is necessary to maintain the balance between red cell production and loss.
