Step by step
Solved in 2 steps
- What is the function of the smooth muscle in the arterial wall?What happens to systemic blood pressure when the smooth muscle of muscular atries contract?As blood vessels increase in diameter, the amount of smooth muscle decreases and the amount of connective tissue increases. Explain why. (Hint: Remember Laplace's law)
