Okay, this question here says, which of the following statements related to blood pressure are true and which are false? so you have four statements here.
00:09
One, two, three and four.
00:12
Okay, so the first one says blood exhibits pulsatile flow throughout the systemic circulation.
00:19
And this one is true.
00:20
Okay, so one is gonna be here.
00:22
Why? well because practically, this blood flow is pulsating arteries and arterioles due to the pumping action of pumping action of the heart.
00:35
As the heart pumps, then there is going to be a pulsatile flow during or of the blood containing arteries and arterioles because they are directly connected to the heart.
00:47
The next one says blood pressure decreases to a few millimeters of mercury as blood flows through the systemic circulation back to the heart.
00:54
And this option is also true.
00:56
Okay, because when your blood is in the arteries or arterioles and then it moves to the tissues and then it goes to the veins, to the venues and then to the veins and then back to the heart, the blood pressure is going to decrease.
01:09
So practically in general, the blood pressure is going to decrease as the blood travels through the systemic circulation and reaches its lowest point in the veins just before returning to the heart...
