The heart has 4 chambers and blood comes into the heart through 2 of those chambers and exits through the other 2.
Oxygen-poor blood enters the heart from the inferior vena cava and superior vena cava, into the right atrium. From there, the blood passes the tricuspid valve and enters the right ventricle. From there, the blood is pumped through the pulmonary valve into the pulmonary arteries and goes to the lungs to dispose of carbon dioxide and collect oxygen.
On the left side of the heart, oxygen-rich blood arrives from the lungs via the pulmonary veins where it passes the mitral valve to enter the left ventricle. From there, the blood is pumped through the aortic valve into the aorta.
your heart!your attiliries carry blood from the heart and your veins carry blood to your heart because they ran out of "food"
yes if i doesnt come out ull die
No. The heart is an organ that pumps blood.
heart valves opening and closing
this is two step process.in the first process blood go from the heart and in the second step blood come into the heart for clean. when it goes from the heart it is cleaned blood,but when it returns it become dirty and our heart performs as a filter and it cleans our blood. this is the chemistry of blood, hopefully you would like it.
yes
No blood does not come from the brain. It comes from the heart. It is pumped and some is sent to the brain and other parts of the body.
If you are asking where blood cells are "made," they are made in bone marrow.
The pushing force that moves blood out of the heart is generated by the contraction of the heart muscle itself. When the heart contracts, it creates pressure that pushes blood into the arteries, allowing it to circulate throughout the body.
Oxygenated blood is carried by the pulmonary vein. This vein transports blood from the lungs to the heart.
Carries oxygenated blood from the lungs to the left atria of the heart. Brings blood from the lungs to the heart.
The heart must come from a person with the same blood type as the patient, unless it is blood type O negative. A blood type O negative heart is a universal donor and is suitable for any patient regardless of blood type.
