the blood is given oxygen as it passes next to the alveoli in the lungs.
The process by which the blood gets oxygen is called diffusion
Blood Cells?
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.
oxygen and carbon dioxide. oxygen is delivered by the blood into the cell and oxygen from the cell is is given to the blood in exchange to be expelled by the lungs.
deoxygenated blood
Dissolved
The oxygen is given by way of diffusion in the capillary system. Oxygen is not taken actively by the cells. So some oxygen is bound to be there in the deoxygenated blood. You have roughly half the oxygen, that comes back in deoxygenated blood.
Dissolved
The protein hemoglobin, which carries oxygen in the blood and appears brighter red in the vessels that carry oxygen. In the veins, the hemoglobin has already given up most of its oxygen to the body. Therefore the blood turns a darker red.
Oxygen saturation or dissolved oxygen (DO) is a relative measure of the amount of oxygen that is dissolved or carried in a given medium. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. Blood oxygen saturation level refers to the percentage of a person's red blood cells that are loaded or filled with oxygen. Oxygen is carried by the red blood cells to organs, such as the brain and the heart. If the blood oxygen level is too low, not enough oxygen is carried to the organs. Without an adequate blood oxygen level, the body cannot function normally.
Yes, anemia refers to a low number of erythrocytes in the blood, and therefore less oxygen can be transported at a given time.
It is actually the name given to the molecule found in the RBCs that is carrying oxygen. It is called oxyhemoglobin.
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.
