What blood vessel which regulates systemic resistance. A.veins B.arteries C.arterioles d.capillaries?
The arterioles are most responsible for determining systemic vascular resistance. And small ateries and Venules are also act as resistance vessels.Resistance vessels react to the sympathetic and nervous regulations .When sympathetic n. s. is excited blood vessels constricted and blood floor reduced. Its a method of heat saving in cold weather.
What factors influences resistance to blood flow in the arteries?
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
Which vessel carries blood to systemic organs?
Aorta
What is the first blood vessel of systemic circulation?
The aorta.
What blood vessel is not part of the systemic circulation?
The Vein does not bring blood to the Heart.
A resistance to blood flow due to friction between blood and blood vessel walls is called what?
it is called peripheral resistance.
Which of the following layers (or tunics) of a blood vessel is the most critical in requlating systemic blood pressure?
Tunica media
What nuclei regulates the contraction of smooth muscle in blood vessel walls?
vasomotor center
What three variables affect peripheral resistance to blood flow?
Resistance is determined by three properties: the lengthand cross-sectional area of a material, and its resistivity. Since resistivity is affected by temperature, you could say that temperature indirectly affects resistance.
What are the main factors that contribute to total peripheral resistance?
Blood vessel diameter,blood viscosity and total vessel length
Which blood vessel that has the highest temperature when the body is at rest?
Systemic veins & venules
What is determined by stroke volume x heart rate x systemic vascular resistance?
This is the best mathematical way to understand blood pressure. Blood pressure = (stroke volume x heart rate) x systemic vascular resistance.
