How is the structure of a red blood cell related to its function?
- A.
Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which O2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)
- B.
Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which CO2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)
- C.
Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which N2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)
- D.
Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which O2 binds, Thus helps RBC transport oxygen (O2) and nitrogen (N2)
Correct Answer
A. Packed with hemoglobin, Hemoglobin molecule includes heme groups that each have iron atoms to which O2 binds, Thus helps RBC transport oxygen (O2) and carbon dioxide (CO2)Explanation
The structure of red blood cells, packed with hemoglobin, allows them to bind and transport oxygen (O2) and carbon dioxide (CO2).Rate this question:
-
- 7.
Does the hormone erythropoietin regulate RBC production?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Erythropoietin is a hormone produced primarily by the kidneys, and it regulates the production of red blood cells (RBCs).Rate this question:

D. All of the aboveExplanation
Each type of white blood cell has a specific function in the immune response. Neutrophils fight bacterial infections, eosinophils fight parasitic infections and play a role in allergic reactions, basophils release histamine during allergic reactions, monocytes differentiate into macrophages and dendritic cells, and lymphocytes (B cells and T cells) are involved in the adaptive immune response.Rate this question:

All of the above
Correct Answer
D. All of the aboveExplanation
Hemostasis, the process of stopping bleeding, involves three steps: vascular spasm (constriction of blood vessels), platelet plug formation (platelets stick together to form a plug at the site of injury), and coagulation (formation of a blood clot).Rate this question:
-

- B.
7 days
- C.
120 days
- D.
