B: The transport oxygen and nutrients around your body and help to get rid of wastes
Explanation:
The circulatory system carries oxygen and nutrients to the body, but it can also help get rid of waste (though that isn't a huge function of it).
The partial pressure of oxygen, P(O₂) is 198.83 mmHg.
<h3>What is partial pressure of a gas?</h3>
The partial pressure of a gas is the pressure gas will exert in a mixture of gases which do not react chemically together.
The sum of partial pressure of gases at atmospheric pressure = 760 mmHg
P(N₂) + P(H₂O) + P(CO₂) + P(O₂) + P(other) = 760 mmHg
P(N₂) = 0.72 atm = 547.2 mmHg
P(H₂O) = 7.7 torr = 7.7 mmHg
P(CO₂) = 0.37 mmHg
P(other) = 0.97 kPa = 5.9 mmHg
P(O₂) = 760 - (547.2 + 7.7 + 0.37 + 5.9) = 198.83 mmHg
Therefore, the partial pressure of oxygen, P(O₂) is 198.83 mmHg.
