Weekly Quiz Competition

Question 1
1 / -0

Which parts of the heart pumps deoxygenated blood to the lungs?

A
1, 2 and 6

B
1, 2 and 7

C
2, 4 and 6

D
3, 4 and 5

E
3, 4 and 8

Solution

Both venae cavae (7) pass the deoxygenated blood to the right atrium. Blood from the right atrium (1) enters right ventricle (2) and pulmonary arteries (6) carry deoxygenated blood from right ventricle to lungs for oxygenation. Two pulmonary veins (8) come from each lung and pass oxygenated blood to left atrium (3). The left ventricle (4) pumps blood into the aorta (5) which in turn branches and delivers blood to the major body regions and organs. So, the correct answer is option A.
Question 2
1 / -0

Which of the following carries carbon dioxide during exhalation?
I. Plasma
II. Erythrocytes
III. Haemoglobin molecules

A
I only

B
II only

C
III only

D
I and II

E
I, II and III

Solution

Carbon dioxide (CO$${_2}$$) is carried in human body in 3 different ways:- (i) CO$${_2}$$ is highly soluble in the blood. So it remains dissolved in the plasma. (ii) CO$${_2}$$ remains attached to the haemoglobin and forms a reversible compound called carbamino-haemoglobin. (iii) CO$${_2}$$enters into erythrocytes, gets converted into carbonic acid by carbonic anhydrase and finally into bicarbonate ions.
Hence the correct option is D.
Question 3
1 / -0

The correct pathway of blood circulation in the human body is

A
Heart $$\rightarrow$$ Pulmonary vein $$\rightarrow$$ Capillary $$\rightarrow$$ Pulmonary artery $$\rightarrow$$ Heart

B
Heart $$\rightarrow$$ Pulmonary artery $$\rightarrow$$ Lungs $$\rightarrow$$ Pulmonary vein $$\rightarrow$$ Body systems $$\rightarrow$$ Heart

C
Heart $$\rightarrow$$ Pulmonary artery $$\rightarrow$$ Lungs $$\rightarrow$$ Pulmonary vein $$\rightarrow$$ Heart $$\rightarrow$$ Body systems

D
Body systems $$\rightarrow$$ Lungs $$\rightarrow$$ Heart $$\rightarrow$$ Vein $$\rightarrow$$ Capillary $$\rightarrow$$ Artery.

E
Heart $$\rightarrow$$ Pulmonary artery $$\rightarrow$$ Lungs $$\rightarrow$$ Body systems $$\rightarrow$$ Vein $$\rightarrow$$ Heart.

Solution

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the ventricle contracts, blood leaves the heart through the pulmonary valve, into the pulmonary artery and to the lungs, where it is oxygenated.

So, the correct option is 'Option C'.
Question 4
1 / -0

Study the diagram given below and identify the cells labelled as A, B, C and D, and choose the correct option.

A
A = Eosinophil, B = Erythrocyte, C = Neutrophil and D = Basophil

B
A = Eosinophil, B = Lymphocyte, C = Neutrophil and D = Monocyte

C
A = Erythrocyte, B = Basophil, C = Neutrophil and D = Lymphocyte

D
A = Eosinophil, B = Monocyte, C = Neutrophil and D = Lymphocyte
Solution
- The diagram shows the different types of blood cells.
- The label A refers to eosinophils. The nucleus of these cells is bilobed. They are involved in allergic and inflammatory reactions.
- The label B refers to monocytes. They have a kidney-shaped nucleus.
- The label C refers to neutrophils. They have a multilobed nucleus. the monocytes and neutrophils are involved in phagocytosis. The label D refers to lymphocyte. They have a large circular nucleus. They form the immune T cells and B cells.
Thus, the correct answer is option D.
Question 5
1 / -0

Which of the following removes debris from cells?

A
Blood

B
Lymph

C
Interstitial fluid

D
All of the above

Solution

The lymphatic system can be compared with "hazardous waste disposal" because it transports waste products out of the body. These include, for example, proteins, metabolic breakdown products, inflammatory products or fat from the abdominal cavity. The lymphatic system runs alongside the blood vessels and covers our entire body like a net. Lymph fluid normally flows through the network of lymph vessels that connect to a group of lymph nodes. The nodes act as a filter, destroying or trapping anything harmful that the body doesn’t need. The lymph nodes contain white blood cells (lymphocytes), which attack and break down bacteria, viruses, damaged cells or cancer cells. Waste products and the destroyed bacteria are then carried in the lymph fluid back into the bloodstream and are removed from the body with other body waste.

So, the correct answer is 'Lymph '.
Question 6
1 / -0

Which of the following statements about red blood cells in human is/are true?

A
Are released from the bone marrow as mature red blood cells

B
Do no contain mitochondria

C
Have a life span of 120 days in the circulation

D
All of the above
Solution
- The bone marrow produces the cellular elements of the blood, including platelets, red blood cells, and white blood cells. Red blood cells are released from bone marrow as matured RBC.
- They lack a nucleus and other cell organelles, like mitochondria, at maturity.
- When matured, in a healthy individual these cells live in blood circulation for about 100 to 120 days. At the end of their lifespan, they become senescent and are removed from circulation.
So, the correct answer is option D.
Question 7
1 / -0

Lymph is responsible for removal of:

A
Antigens

B
Toxins

C
Interstitial fluid

D
All of the above
Solution
- Antigens are foreign particles that stimulate immune response activating the immune system and WBCs. Antigens are carried by lymph to lymph nodes where they are taken care by lymphocytes.
- Toxins are metabolic wastes or substances secreted by bacteria, viruses or fungi which can be harmful and have to be excreted from the system. Toxins in the interstitial fluid are removed by lymph.
- Interstitial fluid is the extracellular fluid in which cells are bathed. They contain metabolic wastes and $$CO_2$$ which are absorbed into venules. The left out interstitial fluid is removed by lymph vessels.
So, the correct answer is "All of the above".
Question 8
1 / -0

Lymph provides immunity because

A
It has lymphocytes

B
It has erythrocytes

C
It has thromobocytes

D
None of the above

Solution

WBCs are divided into leucocytes and lymphocytes. Lymphocytes are further divided into macrophages and monocytes. These cells help in the engulfment of any foreign particles inhaled or ingested by our body. Lymphocytes are considered as soldier cells of our body. A Large proportion of these cells is found in the lymphatic system wherein the lymph is present. Thus lymph provides immunity. So, the correct answer is option A.
Question 9
1 / -0

Lymph transports white blood cells from

A
Spleen

B
Pancreas

C
Lymph nodes

D
liver

Solution

A. Spleen also referred to as the graveyard of RBCs removes worn-out RBCs and fights infections. It is a part of the lymphatic system
B. Pancreas The lymphatic system of pancreas drains excess fluid that contains leaking hormones and some enzymes from interstitial spaces.
C. Lymph nodes filter the lymph as it passes through these nodes. They board lymphocytes which help in removing wastes and antigens. In case of infection, lymph nodes transport WBCs to blood
D. Liver produces a large amount of lymph, the lymphatic system of liver functions as a tissue drainage system and immunological control system.
So the answer is C
Question 10
1 / -0

According to Best and Taylor's Theory, which of the following does not play any role in blood clotting?

A
Prothrombin

B
Fibrinogen

C
Platelets

D
Calcium ions

Solution

There are various theories which are proposed by different scientists on the phenomenon of blood clotting. The theories explain the components involved and the mechanisms involved in blood clotting. According to Best and Taylor's Theory, four components are involved in blood clotting. These are prothrombin, thromboplastin, calcium ions, and fibrinogen. Thromboplastin released from damaged tissues active the prothrombin to thrombin in the presence of calcium ions. The thrombin activates fibrinogen to fibrin which forms the clot. So, there is no involvement of the platelets in clotting according to Best and Taylor's theory.
Thus, the correct answer is option C.
