Which type of blood cells are responsible for transporting gases?

• Red Blood Corpuscles

• Plasma

• White Blood Corpuscles

• Platelets

Answer explanation

What is the average life span of Red Blood Corpuscles?

• 1-2 weeks

• 3-4 months

• 1 year

• 6-8 months

Answer explanation

The average life span of Red Blood Corpuscles is 3-4 months.

Which type of white blood cells are involved in local anticoagulation and formation of ground substance?

• Neutrophils

• Eosinophils

• Lymphocytes

• Basophils

Answer explanation

Basophils are involved in local anticoagulation and formation of ground substance. They release heparin and histamine, which prevent blood clotting and promote inflammation.

What is the function of Basophils in the body?

• Phagocytosis

• Neutralize histamine

• Antibody formation

• Local anticoagulation

Answer explanation

Basophils function to neutralize histamine in the body.

What is the average life span of Platelets?

• 3-6 months

• 1-3 days

• 5-9 days

• 2-4 weeks

Answer explanation

Platelets have an average life span of 5-9 days, making them crucial for blood clotting and wound healing.

Which protein is responsible for initiating blood clotting by activating conversion of prothrombin to thrombin?

• Prothrombin

• Heparin

• Thromboplastin

• Fibrinogen

Answer explanation

Thromboplastin is the protein responsible for initiating blood clotting by activating conversion of prothrombin to thrombin.

What is the specific gravity range of whole blood?

• 1.055-1.060

• 1.040-1.045

• 1.070-1.075

• 1.080-1.085

Answer explanation

The specific gravity range of whole blood is 1.055-1.060. This range is the correct choice.

Which type of blood cells are non-nucleated and incapable of cell division and multiplication?

• Monocytes

Answer explanation

Red Blood Corpuscles are non-nucleated and incapable of cell division and multiplication.

What is the main function of Lymphocytes in the body?

• Phagocytosis

• Wound healing

• Antibody formation

• Neutralize histamine

Answer explanation
