Blood is oxygenated in the lungs!
The place is the same for both; the alveoli in the lungs.
it undergoes transformation into another rock.
it undergoes transformation into another rock.
Oxygen exchanges with CO2 (Carbon dioxide) to "purify" blood. This takes place in the aveoli (in the lungs) the blood is transported via blood vessels. Kidneys also purify blood
It is part of the reproductive system. it is the opening to the birth canal
since the air in lungs have more oxygen than the blood in the surrounding, the oxygen will be difused to the blood, similerly the quantity of carbon dioxide in the surrounding blood will be more compared to that in the lungs. so again difussion takes place, thus happens the exchange. no osmosis(the exchange of water from a place with a high concentration of water to a place with low concentration of water) but there is diffusion.
Oxygen enters the blood in the alveoli of the lungs
When the right ventricle contracts it is pushes blood to the pulmonary arteries and to the capillaries of the lungs where exchange of gases takes place
in the micro air sacs
