Which describes the partial pressures of systemic cells under resting conditions?
Irina18 [472]

The conditions which describe the partial pressures of systemic cells under resting conditions are:

  • Relatively constant partial pressure of gases
  • PCO₂ of 45mm Hg, and
  • PO₂ of 40mm Hg

<h3>What are systemic cells?</h3>

Systemic cells are cells of the body which receive oxygen from the capillaries during respiration and gaseous exchange.

The systemic cells receive oxygen-laden blood from the capillaries and transfer carbon dioxide into the blood capillaries.

The conditions which describe the partial pressures of gases of systemic cells under resting conditions are as follows:

  • Relatively constant partial pressure of gases
  • Partial pressure of carbon dioxide, PCO₂ of 45mm Hg, and
  • Partial pressure of oxygen, PO₂ of 40mm Hg

In conclusion, the partial pressure of the gases in systemic cells under resting conditions are fairly constant.
