When blood is oxygen-rich, it is bright red. Therefore, when blood is oxygen-poor, it is darker in color. When oxygen-poor blood flows through the lungs from the pulmonary arteries, it gets rid of the carbon dioxide and picks up oxygen, which then becomes oxygen-rich blood with a bright red color.
Blood will appear bright red when it has high oxygen content. This is because oxygen binds to hemoglobin in red blood cells, forming oxyhemoglobin, which gives the blood its bright red color.
no you have oxygen high blood.
Deoxygenated blood is low in oxygen and high in carbon dioxide.
Oxygen.
Blood is bright red due to the high concentrations of oxygen in it. This blood is known as oxygenated blood. Blood that appears dark in color or "blue" is blood that has been used by the body and has a higher concentration of carbon dioxide in it. This blood in known as deoxygenated blood!
The pulmonary vein carries blood from the lungs back to the heart, and it has a high oxygen content because the blood picks up oxygen in the lungs during gas exchange.
Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
All blood coming from the heart travels through arteries but not all have high levels of oxygen.The blood that goes to the body is high in oxygen but the blood that goes to the lungs is low in oxygen.There it drops of carbon dioxide and picks up oxygen and carries this back to the heart to be pumped out to the body.
oxygen
The left atrium of the heart receives blood high in oxygen from the lungs via the pulmonary veins. This oxygen-rich blood is then pumped into the left ventricle before being circulated throughout the body.
