Question

Intrinsic control:

a. usually involves the endocrine or nervous system.
b. operates at the cellular level.
c. is sometimes called autoregulation.
d. operates at the system or organism level.

Answer 1

Intrinsic control, also known as autoregulation, operates at the cellular level and does not typically involve the endocrine or nervous system. It relies on local mechanisms such as chemical signals and myogenic controls to adjust blood flow and perfusion in each region of tissue.

Step-by-step explanation:

Intrinsic control is a self-regulatory mechanism that operates at the cellular level. It is sometimes called autoregulation and does not typically involve the endocrine or nervous system. Instead, intrinsic control relies on local mechanisms such as chemical signals and myogenic controls to adjust blood flow and perfusion in each region of tissue. For example, autoregulation allows tissues to adjust their blood flow based on their metabolic needs.
