The gas exchange between the blood and the somatic cells (body cells) takes place in the capillaries of the circulatory system.
Oxygen rich blood leaves the heart through the large arteries, moving into the arterioles, smaller vessels carrying oxygen rich blood, on to the capillaries. Capillaries are tiny vessels which have porosity in their walls, through which gasses and nutrients may exchange. The capillary beds, when looking at a diagram of the circulatory system, the blood vessels turn from red to blue signifying oxygen rich (red) to oxygen poor blood.
The blood then begins its journey back to the pulmonary artery and heart, through the venules and veins.
Hope that answers your question!
In capillaries
Those tiny and beautiful blood vessels are called as capillaries. You have millions of them in your body. The nutrition and oxygen is given out, at the proximal end. The metabolic wastes and carbon bi oxide in taken in, at the distal end.
Internal Respiration."Internal respiration is the diffusion of gases between blood and interstitial fluid across the endothelial cells of capillary walls."Says my Anatomy Book.
CO2 exchanged to blood through capillaries and blood to alveoli
Diffusion
Red blood cells are far and away the most numerous blood cells in the body.
There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.
Diffusion
Diffusion
Diffusion
Nutrients are exchanged between the blood and body cell in the capillaries.
capillaries
Capillary: A tiny blood vessel where substances are exchanged between the blood and the body cells.
Diffusion
Substances exchanged through diffusion between blood and cells.So capillaries should be near to cells.
The blood is oxygenated that is oxygen which has been inhaled is added to the blood and the blood then transports it to other body parts.
Those tiny and beautiful blood vessels are called as capillaries. You have millions of them in your body. The nutrition and oxygen is given out, at the proximal end. The metabolic wastes and carbon bi oxide in taken in, at the distal end.
diffusion is when the materials go through the cell membrane between the capillaries (because capillaries are only one cell thick)
