2014
✓ Answer:DSlightly alkaline
Normal human blood pH is approximately 7.35–7.45, with an average near 7.4, making it slightly alkaline.
63
Which blood cells help in clotting of blood and stop bleeding?
RRB Group-D
28/09/2022 (Shift-II)
2022
✓ Answer:APlatelets
Platelets adhere to damaged vessels, form a platelet plug and support blood clotting, which limits blood loss.
64
Which of the following circulates around the body and plugs the leaks by helping to clot the blood at the points of injury?
RRB Group-D
13/09/2022 (Shift-III)
2022
✓ Answer:APlatelets
Platelets adhere to damaged vessels, form a platelet plug and support blood clotting, which limits blood loss.
65
Blood pressure is the force:
RRB NTPC (Stage-I)
08/03/2021 (Shift-I)
2021
✓ Answer:DThat blood exerts against the wall of a vessel
Blood pressure is the pressure exerted by circulating blood on blood-vessel walls.
66
In human beings, which of the following has a high affinity for oxygen?
RRB NTPC (Stage-I)
12/01/2021 (Shift-II)
2021
✓ Answer:BHaemoglobin
Haemoglobin is the iron-containing pigment in red blood cells. It binds oxygen in the lungs and transports it to body tissues.
67
A person with AB blood group:
RRB NTPC (Stage-I)
31/03/2016 (Shift-II)
2016
✓ Answer:CCan receive blood from any blood group
In the ABO system, AB individuals lack anti-A and anti-B antibodies and are universal red-cell recipients. Rh compatibility and crossmatching still matter.
68
_____ is divided into four parts.
RRB JE
31/05/2019
2019
✓ Answer:DHeart
The human heart has four chambers: two atria and two ventricles.
69
Which of the following metals is present in haemoglobin?
RRB NTPC (Stage-I)
29/04/2016 (Shift-I)
2016
✓ Answer:BIron
Iron (Fe) is present in the haem groups of haemoglobin and enables oxygen binding. It is essential for normal haemoglobin formation.
70
The blood carried by arteries is generally rich in:
RRB NTPC (Stage-I)
28/03/2016 (Shift-I)
2016
✓ Answer:AOxygen
Systemic arteries generally carry oxygen-rich blood. Pulmonary arteries carry deoxygenated blood and are an exception.
