Question 54 relates the pumping blood through the lungs.
00:06
So the lungs is one of the organ that would come under respiratory system.
00:12
Besides helping the respiratory system and exchange of gas, it also helps etan other system, which is called as a circulatory system.
00:20
Meaning converting the deoxygenated blood return as db to that of oxygenated blood written as ob.
00:28
So when the blood is pumped from the lungs through the body and back to the lungs, it is the center done by the circulatory system in order to convert the deoxygenated blood to oxygenated blood.
00:42
Hence, the answer to this question is option c stating cardiovascular system.
00:50
Question 55 discusses about the blood vessels.
00:54
So the blood vessels are of two important types.
00:57
The first one, it is the arteries and other one it is the veins so it should be noted that means are the blood vessels which should carry the blood from the body parts to that of the hearter so here it is the one the pressure in turn it is increasing the body parts in order to be pumped to the heart so the body parts in turn are made up of muscles which are called as the skeletal muscles and besides this the valves that is there are only one -way valve which in turn it is present in the wear veins.
01:30
So this one -way valve and also the pressure excreted by the skeletal muscles during the activity of compression, pressurizes the veins to pump the blood towards the heart.
01:41
Hence the answer to this question is option c stating skeletal muscles.
01:52
Question 56 discusses about the muscles which will move the blood through arteries.
01:57
Artaries are the blood vessels which will pump the blood from heart to that of the body parts.
02:03
So the pressure in turn it is then high in the case of hearts and these heart is then made up of muscles which are called as the cardiac muscles.
02:13
So the muscles which are involved in pumping of blood through arteries is the cardiac muscles and hence the answer to this question is option d.

Question 57 discusses about dorsal or posterior...
