101
Why is the pulse rate of the human body examined?
RRB NTPC (Stage-I)
30/04/2016 (Shift-I)
2016
✓ Answer:ATo check the functioning of the heart
The pulse reflects the rate and rhythm of heartbeats and helps assess cardiac function.
102
How many litres of blood does an adult human have?
RRB NTPC (Stage-I)
18/04/2016 (Shift-I)
2016
✓ Answer:C5
An average adult has approximately 5 litres of blood, although volume varies with body size.
103
Cardiac muscles are:
RRB Group-D
05/10/2018 (Shift-II)
2018
✓ Answer:BCylindrical, branched and uninucleated
Cardiac muscle cells are branched and striated and typically have one central nucleus, though some have two.
104
The normal human heartbeat on average is _____ per minute.
RRB JE
23/05/2019 (Shift-III)
2019
✓ Answer:C60–100
The usual resting heart-rate range for adults is 60–100 beats per minute.
105
Which of the following describes heart functioning more appropriately?
RRB NTPC (Stage-I)
19/04/2016 (Shift-II)
2016
✓ Answer:BEchocardiogram
An echocardiogram uses ultrasound to show heart structure, movement and pumping function. An electrocardiogram records electrical activity.
106
Which of the following is the duct that originates from the heart and transports blood to various organs in the body?
RRB Group-D
05/11/2018
2018
✓ Answer:CArtery
Arteries carry blood away from the heart. Systemic arteries distribute it to the body's organs.
107
On which organ of the human body is angioplasty performed?
RRB JE
31/05/2019 (Shift-III)
2019
✓ Answer:CHeart
The intended answer is heart: coronary angioplasty opens narrowed coronary arteries supplying the heart. Angioplasty can also be performed in other blood vessels.
