Question 1
1 / -0

In a standard ECG which one of the following alphabets is the correct representation of the respective activity of the human heart ?

A
P-depolarisation of the atria

B
R-repolarisation of ventricles

C
S-start of systole

D
T-end of diastole

Solution
Question 2
1 / -0

In which of the following ways does the circulatory system of animals differ from the vascular system of plants ?

A
The circulatory system of animals forms loops, whereas the sap of plants does not circulate.

B
The sap of plants flows through cells, whereas the blood of animals flows through multicellular organs called blood vessels.

C
The internal transport system of plants can lift fluids to greater heights than the internal transport system of animals.

D
All of the above.

Solution

The plants do not have a circulatory system hence fluids do not circulate but are transported. Plants have specialized cells like vessels and sieve tubes through which fluids are transported but animals have blood vessels for transportation. Plants achieve the transport of water and minerals to great heights than the transport system of animals
So, the correct answer is 'All of the above'
Question 3
1 / -0

Which chamber is the first to receive oxygenated blood from the lungs in the figure given below?

A
W

B
X

C
Y

D
Z

Solution

The human heart has a double circulation. The blood flows from the right atrium into the right ventricle, and then through the pulmonary artery, it is pumped to the lungs for oxygenation. From the lungs, the blood flows via the pulmonary veins, into the left atrium, and then passes into the left ventricle.
So, the correct answer is option A.
Question 4
1 / -0

The type of circulatory system in humans is

A
Open

B
Closed

C
Both open and closed

D
Half open and half closed
Question 5
1 / -0

Blood vessel carrying blood from lung to heart is

A
Pulmonary artery

B
Pulmonary vein

C
Coronory artery

D
None of the above

Solution

Pulmonary vein carries oxygenated blood from the lungs into the left auricle. This is an exception as veins generally carry deoxygenated blood.
So, the correct answer is option B.
Question 6
1 / -0

Erythropoiesis may be stimulated by the deficiency of

A
Iron

B
Oxygen

C
Protein

D
None of the above

Solution

The process of formation of red blood cells is known as erythropoiesis. RBC help in oxygen transport and therefore RBC production is stimulated by oxygen deficiency
So, the correct answer is 'Oxygen'
Question 7
1 / -0

Which blood cells transport oxygen?

A
Red

B
White

C
Both A and B

D
None of the above

Solution

Erythrocytes or red blood cells (RBC) are the most abundant of all the cells in blood. A healthy adult man has, on an average, 5 millions to 5.5 millions of RBCs per cubic mm of blood. RBCs are formed in the red bone marrow in the adults. RBCs are devoid of nucleus in most of the mammals and are biconcave in shape. They have a red coloured, iron containing complex protein called haemoglobin, hence the colour and name of these cells. These molecules play a significant role in transport of respiratory gases like oxygen and carbon dioxide.
Hence the correct option is A.
Question 8
1 / -0

Which of the following statement(s) is (are) true about heart?

A
Left atrium receives oxygenated blood from different parts of body while right atrium receives deoxygenated blood from lungs.

B
Left ventricle pumps oxygenated blood to different body parts while right ventricle pumps deoxygenated blood to lungs.

C
Left atrium transfers oxygenated blood to right ventricle which sends it to different body parts.

D
Right atrium receives deoxygenated blood from different parts of the body while left ventricle pumps oxygenated blood to different parts of the body.

E
Both B and D.

Solution

Right atrium receives deoxygenated blood through the Vena Cavas or big veins and then the blood is passed on to right ventricle through the tricuspid valve.
Right ventricle pumps deoxygenated blood to lungs through Pulmonary artery.
After oxygenation in lungs
Left Atrium receives oxygenated blood through Pulmonary vein and passes it to Left Ventricle through Bicuspid or Mitral valve.
Left ventricle pumps blood to entire body through the Aorta.
Question 9
1 / -0

The chief function of lymph nodes in mammalian body is to

A
Produce RBCs

B
Collect and destroy pathogens

C
Produce a hormone

D
Destroy the old and worn out red blood cells
Solution
- Lymph nodes are the oval-shaped lymphatic organ scattered throughout the body and play an important role in the body's defense mechanisms.
- It is majorly composed of WBC and devoid of RBC.
- Lymph nodes do not perform the endocrine function.
So, the correct answer is option B.
Question 10
1 / -0

Pulmonary veins pour ______ blood into the left atrium.

A
Oxygenated

B
Deoxygenated

C
Both A or B

D
Mixed

Solution

The pulmonary veins are blood vessels that carry oxygenated blood from the lungs and drain into the left atrium of the heart. There is a total of four pulmonary veins; two from each lung. Pulmonary veins are the only veins in the body that carry oxygenated blood. So, the correct answer is option A.
