Heart move blood by pumping action mechanism so also called pumping organ of body. Wall of heart is histologically form of cardiac muscles fibers, while internally the heart is formed of a number of chambers interconnected to one another. Human heart which is also called myogenic heart in whcih the cardiac impulse originates in the cardiac muscle fibers and is not broght to the heart by the nerve fiber. In heart a node known as SA node originate the effectve impulse and these impulse travel throughout the heart through bundle of hiss i.e. the network of impulse carring fibers which allow heart to contract and expand in rhythymic manner so the heart cause pulpating sound and also allow the blood to enter and leave out.

∙ 12y agoThe heart has four chambers in it, two chambers made for arteries, which carry blood away from the heart, and two chambers for veins, which carry blood to the heart. These chambers keep the blood that has been oxygenated flowing into the arteries to be administered to the body, and the veins carry back the deoxygenated blood, which goes into your lungs and is renourished with oxygen.

How does the blood to a heart and lung keep flowing in the same direction?
There are two ways that blood is kept flowing in the same direction. The heart is pumping it in that direction, and blood vessels contain valves which prevent blood from flowing in the wrong direction.
What is the flap of tissue that prevents blood from flowing back called?
valve
What is a flap of tissue that prevents blood from flowing backward?
a flap of tissue that prevants blood from flowing backward is
What prevents blood from flowing back into the heart?
The valve
What structure prevents blood from backing up?
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.
What prevents blood from flowing into the chambers it has already passed through?
valves
What prevents blood from flowing in veins?
veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
What structures of the heart keep blood flowing in one direction.?
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.

When ventricles contract the bicuspid valve prevents blood from flowing from-what?
The bicuspid valve, sometimes better known as the mitral valve, allows blood to flow in only one direction (assuming it is functional) from the left atrium to the left ventricle, it prevents blood from flowing back from the left ventricle into the left atrium.
What opens and closes to control the flow of blood in a one-way direction through your heart?
Various valves keep the blood flowing in one direction.
What prevents blood from flowing back into heart?
The valve
What structures of the keep blood flowing in one direction?
One directional valves keep blood in the heart flowing in the right direction. There are three valves: biscupid valve, semilunar valve and tricuspid valve. These open to let the blood flow through then close to prevent the blood flowing back in the wrong direction making the heart less efficient.
Blood in veins is kept flowing in one direction by the presence of?
Valves, allown blood through in one direction when the pressure builds up but close when pressure is applied in the opposite direction.
What prevents blood from flowing backward into the veins?
valves in the veins
What is the tissue that prevents blood from flowing back words?
the valves
