Answer 1

Extrinsic control of blood flow includes mechanisms of the autonomic nervous system and the endocrine system.

Step-by-step explanation:

The extrinsic control of blood flow includes mechanisms of the autonomic nervous system and the endocrine system.

1. Autonomic nervous system: The autonomic nervous system controls blood flow through the sympathetic and parasympathetic divisions. The sympathetic division constricts blood vessels, increasing blood pressure and reducing blood flow, while the parasympathetic division relaxes blood vessels, decreasing blood pressure and increasing blood flow.

2. Endocrine system: The endocrine system regulates blood flow through the release of hormones. For example, epinephrine and norepinephrine released by the adrenal glands can constrict blood vessels and increase blood pressure.
