absorbed through the blood stream
Nitrogen gas cannot be absorbed by plants
Theliver
no because sprem and egg have no blood in them they are just cells (not blood cells)
Velium gas
The heart pumps blood which is a liquid. A certain amount of gas is absorbed by blood (particularly oxygen, which the body needs) but it is not in the form of a gas when the heart pumps it.
In lungs where carbon dioxide is released and oxygen absorbed and in cells where oxygen is given to cells and carbon dioxide is absorbed by blood.
The Nitrogen we breathe IS absorbed by the blood vessels (and all the body tissues). While the Nitrogen gas from the air is inert and does not play any part in body processes, Henry's gas laws require that some of the Nitrogen will be absorbed/dissolve in the blood (and body tissues). This becomes an issue for sub aqua divers where the presence of this dissolved nitrogen causes the "bends".
Henry's law is one of the gas laws, stating that the amount a gas dissolves in a given type and volume of liquid is proportional to the partial pressure of that gas. As pressure builds, more nitrogen and oxygen gets absorbed by the blood in the body, and it tends to get absorbed faster than it gets released, meaning that when you resurface and the pressure declines, the gas in the blood is still increased.
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.
oxygenated blood
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.
it is not absorbed because of dead cells, or pathogen!
All nutrients we have taken are absorbed into the blood in the small intestine. The excess are stored in the liver from where if required is again absorbed into the blood.
The small intestine is where nutrients get into the blood.
