Circulatory system
The cardiovascular or circulatory system is the system of veins, cells and organs that make up and transport blood through your body. The system includes: the heart, blood vessels (including veins, arteries, and capillaries) and the blood (red and white blood cells, platelets and plasma).
A red blood cell's main function is carrying oxygen in the blood to various cells in the body, it uses a protein called haemoglobin for that purpose, where it picks up oxygen in the lungs, or gills in case of fish and releases it in the tissues via the blood. Red blood cells also remove carbon dioxide from the body
Oxygen. Transported in the red blood cells. O2 Diffuses across the alveoli (inside your lungs) into red blood cells in nearby capillaries. Oxygen binds to haemoglobin (a protein inside red blood cells). Carbon dioxide. Soluble in water. Therefore easily dissolves in plasma (the liquid part of blood, which is mostly water anyway), diffuses out of the plasma across the alveoli wall and exhaled
The large artery connected to the heart, called the Aorta.

Capillaries
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.
Oxygen moves through your red blood cells.
blood
Yes. This what happens. The oxygenated blood goes to the heart and is pumped out via arteries and end up in the capillaries where the oxygen is exchanged with carbon dioxide and it moves into the body cells.
Red blood cells contain a chemical called hemoglobin which has the capacity to form a weak bond to oxygen molecules, so that the oxygen will be carried along, through the blood, by the hemoglobin, but will still be released by the hemoglobin later on, and will therefore be able to reach the various cells of the body, all of which need oxygen in order to metabolize food and generate chemical energy with which to function.
The circulatory system (blood) moves oxygen through the body to the cells.
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.
The cell membrane simply accepts it when it is delivered through the blood.
The exchange of carbon dioxide and oxygen occurs in the alveoli. Each alveolus is surrounded by a network of small blood vessels. Like the alveoli, these small blood vessels have extremely thin walls. Blood that enters the vessels has a high level of carbon dioxide, which it picked up from the body tissues. It contains little oxygen. The carbon dioxide leaves the blood and moves through the walls of the blood vessels and alveoli into the lungs. Oxygen from the air in the lungs then passes through the walls of the alveoli and blood vessels and into the blood. The blood, now rich in oxygen, leaves the lungs and travels to the heart. The heart then pumps it to cells throughout the body. The carbon dioxide is finally expelled from the lungs when we exhale.By ichigo kurosaki
blood flows through your body through the pumping of your heart. however on your red blood cells are hemoglobin which holds oxygen.when your blood cells go through your cells...the hemoglobin picks up the oxygen poor blood and deposits it at your lungs (to be realeased thru exhaling) and get oxygen rich blood (from inhaling)
