Solution

The correct option is A one
The statement A is correct because, Hepatic portal vein is present in the abdominal cavity that supplies blood from gastrointestinal tract and spleen to the capillary beds of liver.
The statement B is also right because, heart failure is a state where heart is not able to pump as much as blood as it nis supposed to be. The term "heart failure" is also used when heart is not working at all.
Adrenal medullary harmones cause vasoconstriction, which causes high blood pressure and increases blood flow. Therefore, the statement C is wrong.
Cardiac cycle is the functioning or performance of the heart from the beginning of one heart beat to the beginning of the next heart beat and each heart beat results puts out upto 0.07 L of blood. Therefore, the statement D is wrong.
So, the correct option is ' two'.

What is the approximate amount of blood pumped by each ventricle of the heart during one cardiac cycle?

Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70ml. Now, to get the cardiac output, we have to multiply (i)__ with the normal heart rate of (ii)__ /min and we get (iii)__ ml/min. This means that in one minute, each ventricle of a normal heart pumps about (iv)__ litres of blood out.

Q. The state of heart when it is not pumping blood effectively enough to meet the needs of the body is:
