Peripheral resistance depends on all of the following factors except __________.
pantera1 [17]

Options for the question have not been given. They are as follows:

blood vessel length

blood viscosity

blood vessel diameter

blood colloid osmotic pressure

Answer:

blood colloid osmotic pressure

Explanation:

  • Peripheral resistance is the resistance to blood flow by blood vessels.
  • It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
  • It is also directly proportional to blood viscosity as more energy is required to push viscous material.
  • It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
  • However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.
