Question 1
1 / -0

Blood plasma proteins :
i. decrease in their level causes excessive absorption of water from tissues into blood.
ii. they maintain osmotic pressure.

A
both are correct.

B
both are wrong

C
Statement i) is wrong and ii) is correct.

D
Statement i) is correct and ii) is wrong

Solution

Fibrinogen, globulins and albumins are the major proteins. The albumins help in osmotic balance.

Question 8
1 / -0

Blood pressure is expressed as the ratio of systolic over diastolic pressure. The difference between systolic and diastolic pressure is called pulse pressure. What will be its value for a normal healthy adult?

A
40 mm Hg

B
30 mm Hg

C
70 mm Hg

D
50 mm Hg

Solution

Blood pressure is represented as the ratio of systolic over diastolic pressure. The difference between systolic and diastolic pressure is called pulse pressure. The value of normal healthy pulse pressure is 40 mm Hg.
Question 9
1 / -0

As Soham, ages with chronic CAD the lumen of his coronary artery may get nearly completely obstructed Result is flow of blood to heart tissue is restricted such that the tissue receives inadequate supply of oxygen rich blood and this condition is diagnosed as :

A
Heart failure

B
Hypertension

C
Myocardial ischemia

D
Myocardial infarction

Solution

In case of chronic CAD, the lumen of coronary artery may get nearly completely obstructed that results into restricted flow of blood to heart. The tissue receives inadequate bloods called myocardial ischemia.
Question 10
1 / -0

In our blood :
i. Granulocytes which constitutes maximum percentage of total leucocytes are neutrophils.
ii. Elevated number of neutrophils in blood indicates an acute infection such as appendicitis.

A
both are wrong

B
Statement i) is correct and ii) is wrong

C
both are correct

D
Statement i) is wrong and ii) is correct

Solution

In human blood, granulocytes and agranulocytes types of leucocytes are present. Neutrophils constitute the maximum percentage of total WBCs. Sharp increase in number of neutrophils in blood indicates an acute infection such as appendicitis.
Question 11
1 / -0

In the human heart :
i. The valve between right atrium and right ventricle is tricuspid while valve between left atrium and left ventricle is mitral valve.
ii. Openings of the right and the left ventricles into the pulmonary artery and the aorta are guarded by semilunar valves.
iii. ‘Lub’ the first sound which is low pitched is caused by the closure of semilunar valves while ‘Dub’ the second sound which is high pitched is caused by the closure of bicuspid and tricuspid valves.

A
only ii) and iii) are correct

B
only i) and ii) are correct

C
only iii) is correct

D
only ii) is correct

Solution

The first heart sound (lub) is associated with the closure of the tricuspid and bicuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves.
Question 12
1 / -0

Meghna suffers from allergic asthma. After a blood test her leucocyte count displayed an abnormal increase in the number of :

A
Eosinophils

B
Monocytes

C
Neutrophils

D
Basophils

Solution

In case of allergic asthma, leucocyte count of blood test shows abnormal increase in the number of Eosinophils
Question 13
1 / -0

___________ is a condition where a blood clot forms in the circulatory system.

A
Thrombus

B
Strombus

C
Hematoma

D
None of the above

Solution

Deep vein thrombosis (DVT) is a type of clot that forms in a major vein of the leg or, less commonly, in the arms, pelvis, or other large veins in the body.
Question 14
1 / -0

Each cardiac cycle takes 0.8 seconds to occur. Calculate how many cardiac cycles occur in 4 minutes ?

A
250

B
75

C
400

D
300

4 min = 240 sec. Therefore, 240/0.8 = 300 cardiac cycles.
Question 15
1 / -0

The average diameter of Red Blood Corpuscles of man is

A
7.2 μm

B
8.1 μm

C
9.2 μm

D
10.3 μm

Solution

The average diameter of red blood corpuscles of man is 7.2μm.
Red blood cells are also called RBCs or Red blood corpuscles. RBC transports oxygen to tissues and removes carbon dioxide from the body. Nearly half of the blood's volume i.e 40 to 45% is red blood cells. In humans, mature red blood cells are flexible and oval biconcave disks with an average diameter of 7.2μm.
Question 16
1 / -0

When blood clot starts contracting, a pale yellow fluid starts oozing out. Its name and composition is :

A
Serum = plasma – [thrombin + blood corpuscles]

B
Serum = plasma – [fibrinogen + blood corpuscles]

C
Sera = blood corpuscles – [thrombin + fibrin]

D
Serum = dissolved fibrin – [plasma + blood corpuscles]

Solution

Plasma without the clotting factors is called serum. The clotting factors include fibrinogen and blood corpuscles
Question 17
1 / -0

The left atrium receives deoxygenated blood in :

A
humans

B
lizards

C
pigeons

D
all the above

Solution

The left atrium receives deoxygenated blood in reptiles like lizards.
Question 18
1 / -0

Sarla is on protein-deficient diet. As a result her plasma proteins content is reduced. She may develop symptom like :

A
reduced oxygen supply to tissues

B
swellings of hands and feet

C
high blood pressure

D
diabetes

Solution

Consuming protein deficient diet for longer duration may results into reduction in protein plasma reduction. The symptoms that appear on body includes swelling of hands and feet.
Question 19
1 / -0

Ramesh has Rh antigen and Anti-A as well as Anti-B antibodies in his blood. During blood transfusion he can receive blood from :

A
person with AB positive blood group

B
person with O positive blood group

C
person with AB negative blood group

D
person with O negative blood group

Solution

Since he has both antibodies A and Band has Rh antigen and hence has O + blood group. So, he can receive blood from O-positive blood group.
Question 20
1 / -0

Match the following:

A
a)-ii, b)-iii, c)-iv, d) i

B
a)-iii, b)-i, c)-ii, d)-iv

C
a)-iv, b)-i, c)-ii, d)-iii

D
a)-i, b)-iii, c)-iv, d)-ii
