The given passage has illustrated that the kinds of pressure across different place when blood is circulating. It has illustrated any increase in blood pressure under the loss of arterial wall elasticity.
The passage has not illustrated about capillary pressure during ventricular contraction i.e. 70 mm of Hg. The arteries are going to carry blood away from heart whereas arterioles can regulate blood flow into capillaries. The blood capillaries are the major sites of nutrient exchange. The venules are going to bring and collect blood from various organs & deliver into veins. This arterial system is going to control blood pressure. Pulmonary circuit consists of pulmonary artery and pulmonary veins. Pulmonary circuit is supplied by the right side of the heart.
Thus, the options (d), (c) and (b) are incorrect.
The given passage has illustrated that the kinds of pressure across different place when blood is circulating. It has illustrated any increase in blood pressure under the loss of arterial wall elasticity.
Therefore, the correct option is – a.The ventricular contraction asserts capillary pressure that is about 70 mm Hg..
