Why is the blood flowing to the heart oxygen-poor while the blood flowing to the rest of the body is oxygen-rich?

When the blood is flowing back to the heart, the blood has already given off its oxygen to the rest of the body which means it contain less oxygen concentration in the blood.
and when blood is flowing from the heart to the rest of the body, the blood contains high level of oxygen because they were being given oxygen by the lungs which passes along the heart and the heart pumps it to the rest of the body.

What flap of tissue keeps the blood flowing in the wrong direction?
These are valves, and are found in veins to prevent blood from flowing backwards.
What are the deffects if the speed of the blood circulation is decreased?
You will feel weak because blood will not be flowing in your veins the way it should be and your heart will be pumping slower.
What is the vavle that stops blood from flowing back into the right atrium?
A atrio-ventricular valve is the structure that stops blood flowing backwards into the atria. There is one of these valves on both the left and right sides of the heart.
What is the function of the aortic valve?
The aortic valve functions as a one-way valve between the heart and the rest of the body. Blood is pumped from the left ventricle of the heart, through the valve, and down the aorta, which in turn supplies blood to all of the organs in the body. Between heart contractions, the valve closes, preventing blood from flowing backwards into the heart. The function of the aortic valve is then twofold: (1) It provides a route for which blood can leave the heart, and (2) It prevents blood that has already left the heart from leaking backwards into the heart.
What effects faulty valves would have on a human's blood flow?
valves in the human body are just like water valves, when the heart pumps it pushes blood through veins and arteries. The valves keep the blood in forward motion preventing a back flow. there are valves in the veins but not in the arteries. The valves in the veins keep the unoxygenated blood moving towards the heart to be reoxygenated and keeps it from back flowing into the venus system There are valves in the heart also. there are valves between the upper chambers of the heart (the atria) and the lower chambers (the ventricles. They function the same way, by keeping the blood flowing in the right direction. There are also valve in the heart between the right ventricle flowing towards and thru the pulmonary vein on its way to the lungs and a valve between the left ventricle and the aorta, keeping the reoxygenated blood flowing forward to the rest of the body.
How does oxygenrich blood travel from the heart to capillaries around the body?
through your pulmonary artery and pulmonary vein.
What is the purpose of antiangina drugs?
By relaxing the blood vessels, antiangina drugs reduce the heart's work load and increase the amount of oxygenrich blood that reaches the heart.
Blood that is flowing back to the heart is?
In the cardiac cycle, blood flowing into the heart is called the systole.
Which flaps of muscle keep blood from flowing backward through the heart?
Your heart keeps your blood "flowing"
What keep maths blood from flowing back into the chamber of the heart?
There are valves in the heart - and the larger blood vessels that stop the blood flowing backwards.
Where does oxygen-poor blood become oxygen-rich blood?
To be rich in something means you have a lot of it, right? Well, for our blood to be rich in oxygen, we must have a lot of oxygen in the blood. Oxygen poor would be the opposite...minimal oxygen availability.
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 flow of blood between the heart and lungs called?
The flow of blood from the heart to the lungs and back to the heart is called the pulmonary circulation.The blood flowing from the heart to the lungs would be deoxygenated and blood flowing towards the heart from the lungs would be oxygenated.
What do veins have which prevent blood from flowing towards the heart?
Veins have valves which stop the blood from flowing backwards
Do the upper chambers of the heart receive the blood flowing into the heart?
yes
What heart structure prevents blood from flowing backward?
heart valves
What organ keeps blood flowing in one direction?
The heart is the organ that keeps the blood flowing. Valves in the heart ensure the flow is only in one direction.
