Explanation / Answer

14 ) vessel diameter (c) there are 3 factors thag determine the resistance to flow blood in a single vessel.

Vessel diameter is one of the important because it changes due to contraction and relaxation of vascular smooth muscle in the wall of blood vessel. Further very few changes lead to large changes in resistance

Vessel length donot change significantly and viscosity normally stays within a small range.

16 ) true high blood pressure is maintained by its extended wall which contain elastic fibres and muscles that maintain pressure.
