There are several gases present in blood, including:
Oxygen (O2) - The most abundant gas in the blood, which is essential for cellular respiration.
Carbon dioxide (CO2) - A waste product of cellular respiration that is transported in the blood from the tissues to the lungs, where it is exhaled.
Nitrogen (N2) - Although nitrogen is not used by the body in metabolic processes, it makes up about 78% of the air we breathe and is dissolved in the blood in small amounts.
Argon (Ar) - A noble gas that is present in trace amounts in the blood.
Helium (He) - Also a noble gas that is present in trace amounts in the blood.
In summary, while oxygen and carbon dioxide are the two most important gases in the blood, other gases, including nitrogen, argon, and helium, are also present in small amounts.
