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?
Factors that influence resistance to blood flow include the diameter of blood vessels (smaller diameter increases resistance), length of the vessels (longer vessels increase resistance), blood viscosity (thicker blood increases resistance), and turbulence within the blood vessels (increased turbulence increases resistance).
What are the factors that determine vascular resistance?
The factors that determine vascular resistance include the radius of the blood vessels (smaller radius increases resistance), the length of the blood vessels (longer length increases resistance), the viscosity of the blood (higher viscosity increases resistance), and the presence of any obstructions or blockages in the blood vessels.
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.
What Site has the greatest resistance to blood flow?
The site with the greatest resistance to blood flow is the arterioles, which are small branches of arteries. Arterioles have a high resistance due to their small diameter and ability to regulate blood flow to tissues. This resistance plays a key role in maintaining blood pressure and distributing blood throughout the body.
Is there any diffference between the bloodpressure in the major arteries of neck and the legs in the space?
Yes, there is a difference in blood pressure between the major arteries of the neck and the legs. Blood pressure is normally higher in the major arteries of the neck (such as the carotid arteries) compared to those in the legs (such as the femoral arteries) due to differences in distance from the heart and the resistance of blood vessels in those areas.
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.
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
