Answer :
The veins would soon start to inflate/deflate and this would inevitable leed to them breaking. This would cause spontaneous bruises.
Answer:
The blood would get leak backwards via the damaged valves because of gravity, resulting in swelling.
Explanation:
The heart of a human being comprises four chambers, that is, the two ventricles and two atria. The valves assist in the unidirectional flow of blood towards the lower chambers from the upper chambers, the main function of the valves is to prevent the backflow of blood. Thus, on the basis of the question, it is evident that if the valves get destructed, then leaking of the blood takes place, that is, the blood may leak in the backward direction usually because of gravity, leading to swelling of the body part due to the accumulation of the blood.
