Answer:
A.skeletal muscle pump and C.one-way valves in vein
Explanation:
The venous system is found in the body which aids in the pumping and circulation of blood in the body. This venous system has a low pressure as a result of the pressure gradients and resistance which determines the blood flow rate.
As a result of the skeletal muscle pump and one way valves in vien, it helps in making sure that the system maintains a low pressure.
The Correct options are A and C. The venous sytem has very low presures which presents problems for facilitating venous return, the mechanism utilized by the body to counteract this problem is Skeletal Muscle pump and One way valves in Vain.
Muscle Pump System
As the Question suggest, unlike arterial system, the venous sytem has very low presures which presents problems for facilitating venous return. Venous return is important for balance in blood circulation. It is the rate of blood flow back to the heart.
The Muscle pump system helps in Venous return by increasing the rate of venous return. It uses the skeletal muscles and one way valves for it.
Therefore, we can say that the correct options are A and C.
