This is through the Pulmonary Circulation.
Oxygen-depleted blood can be found in the veins, as it has already delivered oxygen to the body's tissues and is returning to the heart to be reoxygenated in the lungs.
Blood changes color at the lungs because it unloads carbon dioxide and absorbs oxygen. Red blood cells that are carrying oxygen are a brighter red color than red blood cells that are depleted of oxygen.
Oxygen is carried in the body by the blood which gets the oxygen in the lungs and this blood is called oxygenated blood
Yes - oxygen is held in red blood cells (in haemoglobin to be precise). As the blood flows, oxygen is brought all around the body and eventually gets back to the heart and lungs as carbon dioxide (which is what you exhale).
Oxygen is carried in the blood primarily in the form of oxyhemoglobin, where oxygen is bound to hemoglobin, a protein in red blood cells. This allows for efficient transport of oxygen from the lungs to body tissues.
Capillaries in your lungs provide oxygen to the haemoglobin molecules of red blood cells.
The pulmonary circuit is the movement of oxygen depleted blood to the lungs to pick up oxygen and unload carbon dioxide.
Dark blood is blood from which the oxygen has been depleted. Once it is filled with oxygen again (in the lungs), it becomes lighter in color.
Oxygen is carried by hemoglobin in red blood cells, forming oxyhemoglobin. Carbon dioxide is carried in the blood mainly in the form of bicarbonate ions, but also as carbaminohemoglobin and dissolved CO2. These gases are exchanged between the blood and tissues in the lungs and other tissues in the body.
oxygen is carried by the red blood cells, but carbon dioxide is separated from the air you breathe in the lungs, then exhaled.
Lungs
Oxygenated blood is carried by the pulmonary vein. This vein transports blood from the lungs to the heart.
