Internal Respiration
It is called internal respiration, or tissue respiration.
Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body
systemic circulation
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
They are called capillaries and are involved in the process of capillary exchange where they supply each living cell in your body with the nutrients it needs to survive and also carries away their waste products. The tiniest tubes are the capillaries.
Capillaries
The alveoli branch from the bronchioles and are responsible for gas exchange with the pulmonary capillaries. They come in close contanct with the capillaries so the exchange of O2 and Co2 can occur rapidly and easily.
Vessels with extremely thin walls over wich molecules and atoms are transported are called "capillaries".
diffusion is when the materials go through the cell membrane between the capillaries (because capillaries are only one cell thick)
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.
Typically, they are capillaries. Capillaries are the very small blood vessels that run the exchange between the arteries and veins - essentially facilitating the U-turn from the heart, back to the heart. Capillaries are very small, only allowing a single file of blood cells to pass through them.
