✓ Answer:AI–A; II–C; III–B
The heart pumps blood. In systemic circulation, arteries carry oxygenated blood and veins carry deoxygenated blood; pulmonary vessels are exceptions.
22
Blood has a fluid matrix called _____, in which RBCs, WBCs and platelets are suspended.
RRB NTPC (Stage-I)

✓ Answer:BPlasma
Plasma is the liquid matrix of blood. It contains water, proteins and dissolved substances and transports nutrients, hormones, carbon dioxide and nitrogenous wastes.
23
Blood coagulation occurs with the help of:

✓ Answer:CPlatelet cells
Platelets adhere to damaged vessels, form a platelet plug and support blood clotting, which limits blood loss.
24
Two questions are based on a transverse section of the human heart. A labels the thick wall of the left ventricle and B labels a heart valve. Why does A have thick walls, and what is the function of B?
RRB Group-D
22/09/2022 (Shift-I)
2022
✓ Answer:CA: Because it pumps blood to different parts of the body; B: Prevents backflow of blood
The left ventricle has a thick muscular wall to generate pressure for systemic circulation. Heart valves prevent backflow.
25
The blood pressure of a healthy man is:
RRB JE

2014
✓ Answer:C120/80
The conventional textbook reference value for adult blood pressure is 120/80 mmHg: 120 systolic and 80 diastolic.
26
Which of the following is similar to the plasma of blood but is colourless and contains less protein?
RRB Group-D

2022
✓ Answer:BLymph
Lymph resembles plasma but normally contains less protein and lacks red blood cells.
27
What is the fluid matrix of blood called?
RRB Group-D
20/09/2022 (Shift-III)
2022
✓ Answer:BPlasma
Plasma is the liquid matrix of blood. It contains water, proteins and dissolved substances and transports nutrients, hormones, carbon dioxide and nitrogenous wastes.
28
The figure shows the human heart: LA = left auricle, LV = left ventricle, RA = right auricle, RV = right ventricle. Positions 1 and 6 are at vessels entering the atria; 2 and 5 are at atrioventricular openings; 3 and 4 are at ventricular arterial outlets. Where are the valves located?
RRB Group-D
06/10/2022 (Shift-I)
2022
✓ Answer:CAt positions 2, 3, 4 and 5
The mitral and tricuspid valves lie between atria and ventricles. The aortic and pulmonary valves lie at ventricular outlets. These correspond to positions 2, 3, 4 and 5.
29
Which of the following elements is part of heme (haem) of human blood?
RRB NTPC (Stage-II)
14/06/2022 (Shift-II)
2022
✓ Answer:BIron
Iron (Fe) is present in the haem groups of haemoglobin and enables oxygen binding. It is essential for normal haemoglobin formation.
30
Which blood group is referred to as the 'Universal Donor'?
RRB Group-D
30/08/2022 (Shift-III)
2022
✓ Answer:BO
Among ABO groups, O is called the universal red-cell donor group. When the Rh factor is considered, O negative is the universal red-cell donor type.
