Does contraction of the smooth muscle cause blood to move through the veins?

Veins contain valves which allow blood to flow only in the desired direction (toward the heart). Any muscular exertion in the body, any movement of arms and legs, etc., will incidentally put some pressure on the veins, forcing the blood to move in the direction which the valves allow.

Contraction of the smooth muscle in arterioles would decrease blood pressure?
No it would increase BP, as contraction of the smooth muscle in the arterioles will make the lumen (holes) of the arterioles smaller, restricting blood flow.
What nuclei regulates the contraction of smooth muscle in blood vessel walls?
vasomotor center
What is the vasoconstriction?
is a contraction of smooth muscle in the wall of the vessel that help to reduced blood flow and blood loss but will not stop blood loss
When contraction of the smooth muscle in a blood vessel wall results in the vessel is referred to as being in a condition of?
vasoconstriction
Does smooth muscle move blood through the heart?
No. A form of involuntary muscle known as cardiac muscle pumps the blood through the heart.
Blood vessels are what type of muscles?
The walls of blood vessels have smooth muscle, which allow contraction and dilation (for example, in response to temperature changes.
Is tropomyosin found in smooth muscle?
smooth muscle doesn't have troponin, instead it has caldmodulin
What provides the pressure to move blood through the veins and back to the heart?
skeletal muscle contraction that squeezes the blood in the veins.
How is the blood flow through capillary beds locally controlled?
This involves the local control of smooth muscle in microcirculation. The metarterioles function as shunts to bypass capillaries and the rings of smooth muscle at strategic locations . They can contract to increase blood flow through capillaries and vice versa. The pre-capillary sphincters contract and relax in response to local factors only. Its contraction constricts the capillary and decreases blood flow and vice versa.
Why do Arteries have very smooth lining inside them?
becuase it does
The type of muscle that is found in digestive tract and blood vessels?
smooth muscle
When a blood vessel gets damaged contractions of smooth muscle referred to as help constrict the vessels to reduce blood flow?
This is called myosin-regulated contraction. The entire muscle acts as a draw-string and constricts the vessel and slows blood flow.
