When happens when the diameter of the blood vessel decreases?
Blood pressure increases if the diameter of the blood vessel decreases.
Would doubling the length of a blood vessel have the greater effect on vascular resistance?
In which of the following would the blood flow be highest? A) a vessel 0.5 cm in diameter and 4 meters long B) a vessel 1.0 cm in diameter and 10 meters long C) a vessel 0.5 cm in diameter and 2 meters long D) a vessel 1.0 cm in diameter and 2 meters long
Which would have the greater effect on vascular resistance?
decreasing the diameter of a blood vessel by ½by hussain :)
What is Vasolidation?
increase in the diameter of blood vessel. it increases the blood flow
A decrease in the diameter of a blood vessel is termed?
vasoconstriction.
What are the main factors that contribute to total peripheral resistance?
Blood vessel diameter,blood viscosity and total vessel length
Which blood vessel tunic is composed of smooth muscle and controls the diameter of the vessel?
Tunica interna
What is the increase of diameter in a blood vessel called?
Vasodilation: Widening of blood vessels resulting from relaxation of the muscular wall of the vessels. What widens is actually the diameter of the interior (the lumen) of the vessel. The opposite of vasoconstriction.
Why would blood vessel radius have a larger effect on the body than vessel length?
A blood vessel's radius has a larger effect on the body than the vessels length because more blood can flow through a larger blood vessel. A change in the radius will have more of a affect.
Lumen is the size of red blood cells?
The lumen is the size of the inside of the blood vessel. The type of blood vessel that has a lumen approximately the same diameter as a single red blood cell is a capillary.
What is the effect of increased vessel length on blood flow?
The longer the vessel is the more friction it applies on the passing blood, the less the blood flow is.
What is the approximate diameter of a blood vessel?
In different parts of the body the blood vessels are of different diameters. The normal diameter of the aorta is around 2 cm and this would be the largest vessel in the human body, while the smallest, a capillary would be between 0.5 to 2.28 mm in diameter.
