2014
✓ Answer:CFibrinogen
Fibrinogen is a plasma protein made by the liver. Thrombin converts it into fibrin, which forms a mesh in a blood clot.
42
Identify the correct labelling of five white blood cells shown in a diagram. Text description: a has a multilobed nucleus; b has a bilobed nucleus with prominent granules; c has dense granules obscuring the nucleus; d has a large round nucleus with little cytoplasm; e has a kidney-shaped nucleus.
The labels identify neutrophil, eosinophil, basophil, lymphocyte and monocyte respectively. These cells contribute to immune defence.
43
Which of the following components of blood promotes immunity and helps the body fight against germs?
RRB Group-D

2014
✓ Answer:DMercury column
The source key gives mercury column. More precisely, the bulb, inflatable cuff and mercury manometer are connected through tubing in a mercury sphygmomanometer.
45
The normal systolic and diastolic pressure in humans is _____, respectively.
RRB Group-D
23/08/2022 (Shift-II)
2022
✓ Answer:B120 and 80 mm of Hg
The conventional textbook reference value for adult blood pressure is 120/80 mmHg: 120 systolic and 80 diastolic.
46
High blood pressure is also called hypertension, which is caused due to _____.
RRB Group-D
18/09/2022 (Shift-I)
2022
✓ Answer:CConstriction of arterioles
Arteriolar constriction increases resistance to blood flow and can raise arterial blood pressure.
47
Which among the following blood groups is considered the universal donor?
RRB SSE
21/12/2014
2014
✓ 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.
48
What is the normal systolic and diastolic pressure in humans?
RRB Group-D
08/09/2022 (Shift-III)
2022
✓ Answer:D120 mm of Hg / 80 mm of Hg
The conventional textbook reference value for adult blood pressure is 120/80 mmHg: 120 systolic and 80 diastolic.
49
A diagram shows a blood vessel with flap-like valves inside its lumen. Which component of the human circulatory system is shown?
RRB Group-D
18/09/2022 (Shift-II)
2022
✓ Answer:BVein
Many veins have valves that prevent backward flow of blood as it returns to the heart.
50
