Thinking about the pulmonary circuit you should have noticed

Thinking about the pulmonary circuit, you should have noticed that the blood vessel length is much shorter than in the systemic circuit. Can you use this information to explain why the blood leaving the Right Ventricle can be under much less pressure than that leaving the Left Ventricle? The ability of a blood vessel to stretch is known as compliance - why is compliance important for everyday life? Why must the pressure be lower in the capillaries than in the arteries?

Solution

The right ventricle, as opposed to the left ventricle, ejects blood into a low-pressure, high-compliance pulmonary movement. It stores much less blood .Thus, the pulmonary flow is capable of accommodating accelerated blood volumes without increasing pulmonary artery pressure as might arise at the systemic side if similar will increase in drift have been seen inside the aorta.

Compliance is important as it is generated by using increasing a vessel by using a known extent and measuring the exchange in pressure. However, previous steady-nation pressure will be higher than the steady-nation pressure when the extent of fluid is first added.
The vascular compliance is the relationship between the volume of blood within a vascular segment and the blood pressure. For a given quantity of blood pressure, vessels with a high compliance can be filled with large volumes whereas vessels with low compliance can only be filled with small volumes.

The walls of vascular tissue is incredibly elastic. When the blood is pumped from the coronary heart, the strain at the partitions of the arteries proximal to the coronary heart is good, however a variety of that force is absorbed by the walls of the vasculature. As extra distance is covered via the blood in its circulatory path, extra kinetic strength is dissipated by using go with the flow resistance and the vascular walls. By the time the blood reaches the capillary networks, the blood pressure has dropped.
