Select the incorrect statement w.r.t. the circulatory system in humans.

The sino-atrial node can generate the maximum number of action potentials.

Blood pressure in the pulmonary artery is more than that in the pulmonary vein.

The hepatic portal vein drains blood to the liver from the intestine.

Ventricular systole increases the flow of blood into the ventricles from the atria by about 30 percent.

Text Solution

Verified by Experts

The correct answer is:

Ventricular systole refers to the contraction of the ventricles, which pumps blood out of the ventricles and into the arteries (aorta and pulmonary artery). The filling of the ventricles from the atria occurs during atrial systole (when the atria contract) and ventricular diastole (when the ventricles relax and fill with blood). Atrial systole increases the blood flow into the ventricles by about 30 percent, not ventricular systole.
