Question

Peripheral resistance includes all of the following EXCEPT:

a. blood viscosity.
b. blood type.
c. vessel radius.
d. blood vessel length.

Answer 1

Peripheral resistance refers to the resistance encountered by blood as it flows through the blood vessels. It is determined by factors such as blood viscosity, vessel radius, and blood vessel length. The blood type does not affect peripheral resistance.

Step-by-step explanation:

Peripheral resistance refers to the resistance encountered by blood as it flows through the blood vessels. It is determined by factors such as blood viscosity, vessel radius, and blood vessel length. However, the blood type does not affect peripheral resistance. Therefore, the correct answer is blood type (b).
