What else can I help you with?
Does blood ever flow backwards in the heart?
Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
What role do arteries and veins play in the excretory system?
Veins and arteries are in the circulatory system. Therefore that means they have something to do with pumping blood to cells around the body. So I would say that the role the arteries play in the body is that it carries blood to and from the heart to other parts of the body
What type of blood vessel will usually contain blood under high pressure?
Arteries. This is because the heart is pumping the blood away from the heart through the arteries, thus they are very high pressure due to the force of the blood being pushed quickly through a confined space.
Is blood pressure higher in capillaries in arteries?
Arteries, becuase they are directly pumped by the heart while veins are pumped some by your heart and some by muscle movement. Arteries have thicker walls as well to cope with the greater pressure.
What are the vessels called that carry blood away from the heart?
arteries
What does the heart actually DO when you have a heart attack?
Your heart keeps pumping blood. The reason people have heart attacks is because your heart never stops pumping blood but if you aren't active enough and you eat too much fat and cholesterol your arteries get clogged and blood can't pass through but your heart doesn't stop pumping blood.
What move blood to the heart?
Veins and Arteries move the blood throughout your body which are part of the Respiratory System with the help of the heart pumping the blood.
What keeps the heart from overfilling with blood?
arteries and veins. plus the constant pumping of the blood

What is the primary force that moves the blood?
The primary force that moves the blood is the heart. The heart contracts and pumps blood into and out of the heart and into veins or arteries. There is a difference between the two, i suggest looking up these differences. This pumping allows you to have a pulse and thus, live. The primary force that moves the blood is the heart.

Does blood capallaries have valves?
peripheral veins have valves to help get the blood back up to the heart but arteries do not because they have enough pressure from the pumping of the heart to get the blood out to the body.
Can your spleen cause high blood pressure?
Indirectly perhaps, but it is the heart and the system of veins and arteries which are the problem in high blood pressure; the heart is pumping extra hard and/or the arteries/veins are restricted by blockage.
Why is the heart called pumping organ?
Because that's exactly what it does !... The heart muscles contract in a pulsing action - pumping blood through arteries and smaller vessels around the body.
What generates blood pressure?
Blood pressure is generated by the force exerted by the heart pumping blood into the arteries and the resistance encountered by the blood flow in the arteries. The systolic pressure is the pressure when the heart contracts and pushes blood out, while the diastolic pressure is the pressure when the heart relaxes and refills with blood.
Blood flow through the capillaries is steady despite the rhythmic pumping action of the heart because of?
Elasticity of the large arteries.
Which organ and tissue make up the circulatory system?
The heart is the organ responsible for pumping blood, while blood vessels (arteries, veins, and capillaries) function as the tissues through which blood flows in the circulatory system.
What part of the circulatory system that travels thought out the body?
The blood traveling in the veins and arteries, driven by the pumping of the heart.
