Question

Local factors are important for regulating blood flow to tissue capillary beds. For example, in skeletal muscle tissue that is actively contracting, levels of oxygen start to decrease as the oxygen is utilized, and levels of carbon dioxide increase as it is produced during cellular respiration. Decreasing levels of oxygen in the tissue cause the smooth muscle forming sphincters in arterioles to relax.

Answer 1

true

Step-by-step explanation:

In smooth muscle contraction, the sphincters relax in the face of the drop in partial tissue pressure of oxygen, and the increase in protons or positively charged hydrogen molecules. In this way, when the sphincter relaxes, the easier and faster contraction of an autonomous and simultaneous nature is conducted.
