Velium gas
Yes, a liquid becomes a gas when its particles have absorbed enough energy to overcome the intermolecular forces holding them together. This allows the particles to escape the surface and become a gas.
In the nephron, water, glucose, amino acids, and some ions (such as sodium) are absorbed from the filtrate into the blood. Waste products such as urea and excess ions are secreted from the blood into the filtrate to be excreted as urine.
Unfortunately there are different ways that each different types of material does this and as there are many different types of hazardous materials, I don't have space here to list them.However here are a few:mercury vapor - inhaled to lungs and absorbed into the blood theremercury liquid - usually does not enter blood to detectable levelsradon gas - inhaled to lungs and decays to solid elements, deposits in lungs and does not enter bloodpesticides - generally absorbed through the skin then into the bloodgasoline, kerosene, etc. - generally not absorbed into blood, the hazard here is mostly firecarbon monoxide - inhaled to lungs and absorbed into the blood theresulphuric acid, nitric acid, lye, etc. - chemically burns tissues, does not get a chance to enter bloodcyanide - can enter body by many ways; inhalation, ingestion, skin contactmustard gas - blisters any tissue it contacts (e.g. skin, lungs, nose and throat, genitals) and usually does not enter blood to significant levelsnerve gasses - see pesticidesetc.
No, sperm is not absorbed into the bloodstream. Sperm is typically deposited into the reproductive tract during sexual intercourse and travels through the cervix into the uterus and fallopian tubes to fertilize an egg.
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
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.
it is not absorbed because of dead cells, or pathogen!
