1. Which type of white blood cell is associated with the following functions?

Neutrophils (60%): Fight bacterial infections

Eosinophils (2–4%): Fight parasitic infections and play a role in allergic reactions

Basophils (0.5%): Release histamine during allergic reactions

All of the above

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.

5. Does the hormone erythropoietin regulate RBC production?

True

False

Erythropoietin is a hormone produced primarily by the kidneys, and it regulates the production of red blood cells (RBCs).

Explanation

Erythropoietin is a hormone produced primarily by the kidneys, and it regulates the production of red blood cells (RBCs).

Submit

6. What is the function of platelets?

They carry oxygen

They fight infections

They help in blood clotting

They remove waste products

Platelets play a crucial role in blood clotting. They form a plug at the site of injury, preventing excessive bleeding.

Explanation

Platelets play a crucial role in blood clotting. They form a plug at the site of injury, preventing excessive bleeding.

Submit

7. What are the three primary functions of blood?

Transportation, Regulation, Defense

Transportation, Digestion, Defense

Transportation, Excretion, Defense

Transportation, Reproduction, Defense

Blood serves three primary functions: transportation (of nutrients, oxygen, hormones, and waste), regulation (of body temperature, pH, and fluid volume), and defense (against infections and bleeding).

Explanation

Submit

8. Which of the following are steps of hemostasis?

Vascular spasm

Platelet plug formation

Coagulation

All of the above

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).

Explanation

Submit

9. Where are blood cells formed?

Stem cells in the bone marrow (Hematopoietic stem cells)

Yellow Bone Marrow

Red Bone Marrow

Kidneys

Blood cells are formed from hematopoietic stem cells in the bone marrow.
