Question 1
1 / -0

In ECG, what does T-wave represent

A
Diastole of auricles

B
Diastole of ventricles

C
Systole of ventricles

D
Diastole of auricles and/repolarisation of ventricles.
Solution
In a standard ECG (electrocardiogram), the P-wave represents atrial contraction.
The QRS complex represents ventricular depolarization or ventricular diastole.
The T-wave represents ventricular repolarisation or ventricular systole. The end of the T-wave marks the end of the ventricular systole.
So, the correct answer is option C.

C
Statement A is wrong but B is correct

D
Both correct but B is not reason of A

A- 3- (iii),C- 4- (i), D- 2- (ii), B- 1- (iv)

Solution

The following enzymes are involved in the mechanism of blood clotting in human.

Column I (Common name)	Column II (Roman numerical designation)	Column III (Activation product)
A. Prothrombin	$$3.$$ II	(iii) Thrombin
B. Proconvertin	$$4.$$ VII	(ii) Convertin
C. Fibrinogen	$$1.$$ I	(ii) Fibrin
D. Proaccelerin	$$2.$$ V	(iv) Accelerin

Question 5
1 / -0

Number of major vessels pouring blood in right atrium is

A
1

B
2

C
3

D
4.

Solution

The major vessels that pouring blood in right atrium is - the inferior vena cava, the superior vena cava and pulmonary artery channels.
So the correct answer will be option C.
Question 6
1 / -0

Double circulation does not take place in _________.

A
Humans

B
Mammals

C
Birds

D
Fishes

Solution

A. Correct option – D

B. Explanation for correct option –
Double circulation means when the blood passes through the heart twice - E.g. Birds and mammals( including humans).
Fishes have heart with two chambers and the circulation is unidirectional and closed circulatory system .
Hence option D is correct
Question 7
1 / -0

People who have migrated from the planes to an area adjoining Rohtang Pass about six months back :

A
Have more RBCs and their haemoglobin has a lower binding affinity to $$O_2$$

B
Are not physically fit to play games like football.

C
Suffer from attitude sickness with symptoms like nausea, fatigue, etc.

D
Have the usual RBC count but their haemoglobin has very high binding affinity to $$O_2$$
Solution
Correct Option: A

Explanation:
- In order to increase the delivery of oxygen to muscles, the RBC count is increased.
- To allow easy release of oxygen to cells, affinity of oxygen to haemoglobin is decreased.
- In duration of 6 months, people become adapted to the environment in which they live. Since the production of RBCs is increased, people are physically fit to play games like football.
- People will suffer from exhaustion, nausea and fatigue for 1 to 3 days, but after some time they adjust to the environment.
Hence, people who have migrated from the planes to an area adjoining Rohtang Pass about six months back have more RBCs and their haemoglobin has a lower binding affinity to O_2.
Question 8
1 / -0

Which option is correct for the formation of intrinsic factor-X activator complex for blood coagulation?

A
Activated Christmas factor + AHG + phospholipid + $$Ca^{+2}$$

B
Inactivated Christmas factor + AHG + phospholipid +$$Ca^{+2}$$

C
Convertin + AHG + $$Ca^{+2}$$+ FSF

D
Phospholipid - protein complex + Proconvertin

Solution

The Hageman factor XII is activated when it comes in contact with a damaged blood vessel. The activated Hageman factor activates the factor XI. The activated factor XI acts on Chrishmas factor IX to form activated IXa. Factor IXa combines with AHG VIII phospholipid and calcium ions to form a complex called intrinsic factor X activator complex. Thus the correct answer is option A.
Question 9
1 / -0

Which of the following diagrams shows the correct blood circulation.

A
Diagram 4

B
Diagram 3

C
Diagram 2

D
Diagram 1.
Question 10
1 / -0

Megakaryocytes, special cells in the bone marrow that produce cell fragments are called :

A
Leucocytes

B
Erythrocytes

C
Thrombocytes

D
Fibrinogen

Solution

Megakaryocyte is a large bone marrow cell which are responsible for the production of thrombocytes. Thrombocytes help in normal blood clotting.
Hence, he correct option is C.
