left ventricle
Blood enters the left & right atria. Blood entering the left ventricle came from the left atrium.
Blood from the body enters the right atrium. From there it is pumped to the right ventricle, through the lungs, to the left atrium, to the left ventricle, then throughout the body. Then back to the right atrium...
Deoxygenated blood enters the heart via the superior and inferior vena cava.
answer
Your heart pumps your blood, carrying blood cells, throughout the body.
After glucose enters the large intestine, it along with other nutrients are absorbed into the bloodstream. From the blood stream it is carried by red blood cells to all parts of the body, where the glucose enters the interstitial space and is absorbed into the cells through a process called Cooperative transport. It usually uses Na ions for this purpose.
arteries because they carry blood from the heart,carrying oxygen to the blood cells
The heart itself is an organ. The region of the heart that first accepts deoxygenated blood from the body, and from the heart itself, is the right atrium. Blood enters the right atrium via the superior and inferior vana cava, anterior cardiac veins, and the coronary sinus. ^ +Information confirmed. Source: Prentice Hall Biology Book; pg. 944.
The red blood cells carry the oxygen from the lungs round the body. The heart pumps the red blood cells to go around the body. When the oxygen is given to the cells, the red blood cells return to the heart and get pumped back to the lungs while carrying carbon dioxide.
Arteries helps in carrying oxygenated blood from heart to different tissues of body.
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
Both! Blood enters the atria (upper chambers) on both sides of the heart at the same time. Blood from the body, carrying carbon dioxide, enters the right atrium. Blood from the lungs, carrying oxygen, enters the left atrium. The two atria contract together, pumping the blood into the two ventricles (lower chambers). The ventricles then contract, pumping blood out of the heart. Blood from the right ventricle goes to the lungs, where it loses its carbon dioxide and picks up oxygen. It then goes to the left atrium. Blood from the left ventricle goes to the body, where it delivers oxygen and picks up carbon dioxide. See: http://www.bbc.co.uk/science/humanbody/body/factfiles/heart/heart.shtml
Heart goes from the right side, other wise you might have the disease that makes your heart pull from the left side.
Oxygenated blood enters the left side of the heart (atria) via the pulmonary veins
