Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
In the alveoli of the lungs. This is where oxygen diffuses from the lungs into the bloodstream and carbon dioxide diffuses out of the bloodstream and into the lungs.
Blood releases its oxygen into the tissues at the capillary level.
gas exchange takes place in the lungs, and at the cellular level. In the lungs, carbon dioxide and other "waste" gasses are released from the blood to be exhaled, and oxygen is absorbed into the blood. At the cellular level, oxygen is released from the blood into a cell, and carbon dioxide and other "waste" gasses are passed into the blood.
There isnt exactly specific arterioles because every conduction system of Arteries flow from Elastic arteries -> muscular arteries -> arterioles. Arterioles are the smallest of the arteries and produce the greatest vascular resistance of blood. The blood then passes onto capillaries for gas/waste/nutrient exchange.
The lungs mate...
If you do not breathe the blood in your veins and arteries can not flow. The exchange of CO2 and oxygenated blood can not mix and exchange in the heart. The gas from CO2 will suffocate you and you will die.
It is because the capillaries are conducting the gas exchange which will affect the rate of velocity
Alveoli- these are the small sac-like structures where gas exchange occurs with the blood. Its creates an ideal site for gas exchange between the air in the lungs and the blood in the capillaries.
Capillary system is where gas exchange occurs
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
Oxygen
alveoli
red blood cells
It is because the capillary wall is only one-cell-thick. In addition, they have a large total surface area in contact with body cell and the blood flow is low.
It is the smallest blood vessels in the body that carries blood cells ,salts & nutrients to be supplied to tissues & organs.It is a minute(nm) tube that permits flow of minute solutions/gas in minimum molecular form.A capillary is the smallest blood vessel in the body. They are the vessels in which gas exchange occurs.
External Respiration is where gasses are absorbed into the blood through the alveolar capillary beds. Internal respiration is where the gasses are transferred into the cells from the blood.
