Which of the following is NOT a part of the circulatory system?
RRB NTPC (Stage-I)
28/12/2020 (Shift-II)
2020
✓ Answer:ALarge intestine
The large intestine belongs to the digestive system. The heart, blood and blood vessels form the cardiovascular system.
122

2019
✓ Answer:DNerve fibres in the heart
The source key selects D, but the wording is inaccurate. Cardiac Purkinje fibres are specialised conducting cardiac muscle cells, not nerve fibres; they rapidly transmit impulses through the ventricles.
123
What is the normal pulse rate of humans?
RRB JE
28/05/2019 (Shift-I)
2019
✓ Answer:C70–80 beats per minute
The source gives 70–80 beats per minute as a typical value. The broader usual resting adult range is 60–100 beats per minute.
124
What are the small blood vessels under our skin called?
RRB JE
02/06/2019 (Shift-I)
2019
✓ Answer:DCapillary
Capillaries are the smallest blood vessels. They connect arterioles to venules and permit exchange of gases, nutrients and wastes with tissues.
125
Which device controls the heart rate of patients?
RRB JE
27/05/2019 (Shift-IV)
2019
✓ Answer:BPacemaker
An artificial pacemaker delivers electrical impulses to regulate the heartbeat when needed.
126
Which of the following carries blood from the heart to the kidneys?
RRB NTPC (Stage-I)
22/02/2021 (Shift-II)
2021
✓ Answer:CRenal artery
Renal arteries branch from the aorta and carry blood to the kidneys.
127
Pulse beat is measured by _____.
RRB JE
02/06/2019 (Shift-IV)
2019
✓ Answer:DArtery
The pulse is felt in an artery as a pressure wave generated by the heartbeat. The answer is inferred because the printed answer is outside the supplied scan.
