What factors influences resistance to blood flow in the arteries?
Wiki User
∙ 13y ago
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

What are the vessels called that carry blood away from the heart?
arteries
Do arteries pump blood to your body?
No the heart pumps the blood but it does pump the blood through the arteries.
The only arteries in the body carry deoxigenated blood away from the heart are?
The only arteries in the body that move deoxygenated blood away from the heart are the pulmonary arteries. Arteries are blood vessels.
What part of the body do the arteries carry the blood?
Arteries carry blood to all parts of the body.
What do arteries and veins drain?
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
What are the factors affecting peripheral resistance which influence BP?
There are three factors that increase peripheral resistance. These factors include autonomic activity, pharmacologic agents, and blood viscosity. Each factor increases the constriction of arteries, which in turn causes peripheral resistance.
A measure of the flow of blood in arteries is called?
Blood flows away from the heart and is measured as blood pressure. This is a measure of the passage or flow and the resistance of the flow in the arteries.
What factors influence resistance to blood flow?
blood volume
Which of these hormones is likely to cause a rise in blood pressure?
Antidiuretic hormone (ADH) influences blood pressure by causing the small arteries to contract.
What is arterial stiffness?
Arterial stiffness is a general term for the elasticity (or compliance) of the arteries. The hardening or stiffening of the arteries is called arteriosclerosis. The stiffness of arteries influences how hard the heart has to work to pump blood through the body.
What does alcohol do to blood vessels?
Vasodilates them. Arteries increase in diameter size, this reduces the peripheral resistance on the blood. Not necessarily a good thing.
A measure of the flow of blood in atries is called?
Blood pressure refers to the blood flow and resistance in the arteries. The device used to measure blood pressure is the sphygmomanometer or sphygmometer.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
What is mean artery?
the pressure of the circulating blood on the arteries; "arterial pressure is the product of cardiac output and vascular resistance"
Which of the following statements about arteries and veins is false?
Veins can collapse, serving as the blood vessel with the greatest resistance to blood flow in the circulatory system
What are examples of arterioles?
There isnt exactly specific arterioles because every conduction system of Arteries flow from Elastic arteries -> muscular arteries -> arterioles. Arterioles are the smallest of the arteries and produce the greatest vascular resistance of blood. The blood then passes onto capillaries for gas/waste/nutrient exchange.
What are the factors related to blood pressure?
Peripheral resistance and cardiac output
