Question 1
1 / -0

During blood coagulation, vitamin K helps in

A
Formation of prothrombin

B
Formation of thromoboplastin

C
Conversion of fibrinogen into fibrin

D
Conversion of prothrombin to thrombin.

Solution

During blood clotting procedure, vitamin K helps in formation of prothrombin (factor ii) because it is a vitamin K dependant coagulation factor.
So, the correct option is A.
Question 2
1 / -0

Carotid artery carries

A
Impure blood to brain

B
Oxygenated blood to brain

C
Impure blood to kidneys

D
Oxygenated blood to heart.
Solution
The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face.
There are two carotid arteries, one on the right and one on the left. In the neck, each carotid artery branches into two divisions:
The internal carotid artery supplies blood to the brain.
The external carotid artery supplies blood to the face and neck.
So, the correct option is B.
Question 3
1 / -0

A blood group with no antibodies but with both antigens is

A
O

B
A

C
B

D
AB.
Question 4
1 / -0

In ABO system of blood grouping, transfusion is not possible from

A
A to AB

B
B to AB

C
O to AB

D
A to O
Solution
- In the ABO system of blood grouping, A blood group person have A antigen on the surface of the RBC and have antibodies against antigen B in their plasma.
- B blood group person has B antigen on the surface of the RBC and has antibodies against antigen A in their plasma.
- AB blood group person has both A and B antigen on the surface of the RBC and has no antibodies in their plasma.
- O blood group person has no antigen on the surface of the RBC and has antibodies against both antigens A and B in their plasma.
- As O blood group person has antibodies against both antigen A and B we cannot transfuse A blood group to them.
- So, the correct answer is option D.
Question 5
1 / -0

Thrombocytes have a life of

A
3-4 weeks

B
4-5 weeks

C
5-9 days

D
None of the above.
Question 6
1 / -0

Problem related to Rh factor arises when $$Rh^+$$ and $$Rh^-$$ bloods mix up

A
In test tube

B
Through transfusion

C
Through pregnancy

D
Both A and C.
Question 7
1 / -0

Choose the correct function of lymph.

A
Carries digested and absorbed fat from the intestine

B
Returns RBCs and WBCs to lymph nodes

C
Drains excess fluid from extra cellular space back into the blood

D
Both A and D
Solution
Correct Option: D
Explanation:
Lymph carries oxygen, hormones and nutrients to all parts of the body.
It transports antibodies and lymphocytes into the blood.
It maintains the composition of tissue fluid and the volume of blood.
It drains excess fluid present between the cells to the blood.
It prevents invasion of microbes and foreign substances inside the lymph nodes.
Hence, the correct functions of lymph are carries digested and absorbed fat from the intestine and drains excess fluid from extra cellular space back into the blood.
Question 8
1 / -0

Which is false?

A
RBCs are also called leucocytes

B
White blood corpuscles are part of body's defence mechanism

C
Platelets are also called thrombocytes

D
Oxygen is carried in blood after combining with haemoglobin.

Solution

A. RBCs (Red blood cells) are also called erythrocytes.
B. White blood cells are also called as leucocytes. They play an important role in immunity and body's defence mechanism.
C. Platelets are also called thrombocytes. They play an important role in clotting of blood.
D. Haemoglobin is a respiratory pigment which transports oxygen in the body. It combines with oxygen to form oxyhaemoglobin which dissociates to release oxygen in body tissues.
Hence, statement A is false.
So, the correct answer is 'RBCs are also called leucocytes'.
Question 9
1 / -0

Which blood vessel has the largest amount of urea?

A
Renal vein

B
Hepatic vein

C
Hepatic portal vein

D
Dorsal aorta/renal artery.

Solution

Hepatic vein is the blood vessel concerned with largest amount of urea. As liver breaks down amino acids into urea, the veins emerging from liver will have maximum amount of urea within them.
So, the correct option is B.
Question 10
1 / -0

Glucose is carried from digestive tract to liver by

A
Hepatic artery

B
Hepatic portal vein

C
Pulmonary vein

D
None of the above.

Solution

Glucose is absorbed in the small intestine (ileum) and then transported to the liver via a connection between the ileum and the liver, that is the hepatic portal vein.
So, the correct option is B.
