The atmosphere is composed of gases, I water vapour and dust particles. Nitrogen constitutes 78.8%, oxygen contributes 20.94% and argon contributes 0.93% in atmosphere. Other gases include carbon dioxide, helium, ozone, methane, hydrogen, krypton, xenon
Transport of respiratory gases Oxygen is carried in red blood cells. It is attached to a haemoglobin, the red pigment found in rbc. The oxygen is carried around the body attached to haemoglobin, it can then leave the rbc and diffuse into the body cells. ...
The approach is illustrated by calculating the average oxygen and hydrogen density of liquid water around two molecular solutes: water and N-methylacetamide. Molecular dynamics simulations are performed to test the results obtained from the integral equation. It is observed that important microscopic ...
