Artery walls contract Not to move blood forward, but to prevent gravity from having all the blood in lower part of body.
Our nervous system (without medications) sense presure on feet in preparation from laying-sitting standing will contract in legs and dialate in neck to brain.
The pump moves blood forward=Heart. By the time the cycle of circulation is almost complete, and blodd is returning in Veins. Its so far away from the pressure of the pump (heart) Moving forward, it needs help. So, mother nature built veins near muscles. One way doors (valves) inside veins open oneway to return to the right side of the heart. Moving feet-legs, hands-arms push against the outside wall of the vein. When the valves fail you see varicose veins

The force with which the contract causes blood pressure?
the force with which what the contract causes blood pressure
Does blood pressure determine the force exerted by the blood on the walls of the arteries?
Yes it does.
What is definition of blood pressure?
Blood Pressure: Is the force at which blood flows thorugh the arteries of the body.
A measurement of the force in the arteries as the heart pumps?
blood pressure .......
Ventricle force blood directly into what?
The ventricles contract and force the blood under pressure, past the semi lunar valves into the arteries. The closing of the bicuspid and tricuspid valves prevents back flow. At the same time the atria and ventricles relax and blood begins to flow back into them from the veins.
What cause blood pressure?
The force of the heart pushing and pulling blood through the arteries and veins causes a change in the force felt in those areas. This regular change from normal is blood pressure.Changes from the "normal" pressures can be caused by many things, including alcohol, stress, other health issues and old age.BASICALLY: The force with which the ventricals contract
True or false the force of blood against the walls of the arteries is called blood pressure?
True.
Blood preaaure is defined as the force that blood exerts on the inner walls of blood vessels true or false?
True, blood pressure is the force that the blood exerts against the walls of the blood vessels, usually the arteries.
What force pushes blood into the arteries?
The heart is a four chambered muscle whose sole task is to pump blood around the body.
What is blood pressure-?
Blood pressure is the pressure of the blood in the circulatory system, often measured for diagnosis since it is closely related to the force and rate of the heartbeat and the diameter and elasticity of the arterial walls.
The greatest force of the blood against the walls of the arteries during ventricular contraction is called?
That is the Systolic Pressure.
Which term refers to the force exerted as the heart pumps blood from the left ventricle to the arteries and out into the body?
systole
