✓ Answer:BTo help in keeping the body temperature constant
Efficient oxygen delivery supports the high metabolic rate needed to maintain a constant body temperature.
2
What is the name of the glycoprotein produced in the liver which plays an important role in blood coagulation?
Pulmonary veins carry oxygenated blood from the lungs to the left atrium. Systemic veins generally carry deoxygenated blood.
5
The respiratory pigment, haemoglobin, is present in:
RRB Group-D

2022
✓ Answer:CRed blood corpuscles
Haemoglobin is the iron-containing pigment in red blood cells. It binds oxygen in the lungs and transports it to body tissues.
6
In a situation where we get injured and bleeding starts, the loss of blood can lead to a decrease in pressure, which may reduce the efficiency of the pumping system. To prevent this, which cells mainly help in the clotting of blood at the site of injury?
Haemoglobin is the iron-containing pigment in red blood cells. It binds oxygen in the lungs and transports it to body tissues.
10
Which of the following statements is/are correct related to transportation? (I) Arteries are the vessels that carry blood from the heart to various parts of the body. (II) The walls of arteries are thin and elastic. (III) Veins have valves, which ensure that blood flows in only one direction.
Arteries carry blood away from the heart and have thick muscular, elastic walls. Many veins have valves to prevent backflow. Statements I and III are correct.
