Detailed explanation-1: -Haemoglobin molecules inside red blood cells pick up and carry the oxygen. These oxygen-rich cells travel in the blood vessels from the lungs to the left side of the heart. The blood is then pumped around the body. Red blood cells are adapted for the transport of oxygen.
Detailed explanation-2: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
Detailed explanation-3: -The pulmonary vein carries oxygen around the body back to the heart. It, therefore, has the greatest oxygen content. The primary pulmonary artery, also known as the pulmonary trunk, is a blood vessel that leaves the heart. More items
