Oxygen starved tissues can release chemical signals into the blood that can change the diameter of nearby blood vessels delivering oxygen and nutrients to the tissues.In doing so the blood vessels will respond through vasodilation (widening of the vessel).Which muscle type is responsible for this vasodilation?
A) skeletal muscle
B) striated muscle
C) smooth muscle
D) cardiac muscle

Question

Quizplus · Accepted Answer

Smooth muscle is responsible for vasodilation and constriction of blood vessels through the relaxation or contraction of the smooth muscle cells in the vessel walls. Skeletal muscle is responsible for voluntary movement and striated muscle includes both skeletal and cardiac muscle, but neither of these types are directly responsible for vasodilation.
