Throbbing movements called 'pulse' are felt due to:
RRB Group-D
30/09/2022 (Shift-II)
2022
✓ Answer:CBlood flowing in the arteries
Ventricular ejection produces pressure waves that travel along the elastic arterial walls and are felt as the pulse.
32
The liquid part of human blood, called _____, is made of water, salts and protein.
RRB NTPC (Stage-II)
14/06/2022 (Shift-I)
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.
33
Which of the following vessels carries blood away from the heart to various organs of the body, except the lungs?
RRB Group-D
11/10/2022 (Shift-III)
2022
✓ Answer:BAorta
The aorta is the largest artery. It receives blood from the left ventricle and supplies the systemic circulation.
34
Blood coagulation occurs with the help of:
RRB Group-D
26/09/2022 (Shift-II)
2022
✓ Answer:BPlatelet cells
Platelets adhere to damaged vessels, form a platelet plug and support blood clotting, which limits blood loss.
35
In the human heart, the pulmonary vein is connected to the _____.
RRB Group-D
06/10/2022 (Shift-II)
2022
✓ Answer:CLeft atrium
Pulmonary veins carry oxygenated blood from the lungs to the left atrium. Systemic veins generally carry deoxygenated blood.
36
What aids in preventing the mixing of oxygen-rich and carbon dioxide-rich blood in the heart?
RRB Group-D
24/08/2022 (Shift-III)
2022
✓ Answer:AThe wall between the chambers
The septum separates the right and left sides of the heart, preventing mixing of oxygenated and deoxygenated blood.
37
Which of the following options correctly describes the features of arteries?
RRB Group-D
08/09/2022 (Shift-III)
2022
✓ Answer:AThick walls, no valves, blood flows under high pressure, carry blood to different parts of the body
Arteries carry blood away from the heart under relatively high pressure and have thick muscular, elastic walls. They generally lack valves along their length.
38
Which fluid carries absorbed fat from intestine and drains excess fluid from extracellular space back into the blood?
RRB NTPC (Stage-I)
17/01/2021 (Shift-II)
2021
✓ Answer:DLymph
Lymphatic vessels transport absorbed intestinal fats and return excess tissue fluid to the bloodstream.
39
Where is the respiratory pigment in the human body present?
RRB Group-D
24/08/2022 (Shift-II)
2022
✓ Answer:AIn red blood cells
Haemoglobin is the iron-containing pigment in red blood cells. It binds oxygen in the lungs and transports it to body tissues.
40
Lymph transports digested and absorbed intestinal _____.
RRB Group-D
08/09/2022 (Shift-II)
2022
✓ Answer:CFats
Lymphatic vessels transport absorbed intestinal fats and return excess tissue fluid to the bloodstream.
