haemoglobin present in the RBC helps in gaseous exchange and transport in humans .. where as in plants its through stomata , cuticle , lenticels etc....
respiratory
The difference in the partial pressure of the gases in the blood coming to the lungs and the alveoli mediated the gas exchange. Without this difference we wont be able to breathe. Diaphragm in the thoracic cavity plays an important role in exchange of these respiratory gases.
A gas that plays an important role in the weather is Water Vapor because itaffects the weatheris the form of gas H2O (G).
Oxygen supports burning
No. Argon is an inert gas. it plays no role in the human body.
Capillaries are very small blood vessels found within the tissues of the body. Its primary role is to transport blood from arteries to the veins.
North Equatorial Current play an important role in water-mass exchange. It also plays an essential role in water and heat exchange between the tropical and subtropical gyres.
Gas exchange is a function of respiration not digestion.
Alveoli is where gas exchange occurs.
It lowers the area available for gas exchange, therefore gas exchange doesn't happen as quickly or as much as it should.
Capillary system is where gas exchange occurs
The exchange surfaces are moist.
