Vedclass · Answer

(A) The partial pressure of oxygen $(PO_2)$ in the blood capillary is higher $(95 \; mm \; Hg)$ than that of the body cells $(40 \; mm \; Hg)$.Due to this pressure gradient,oxygen diffuses from the capillary blood into the body cells.Conversely,the partial pressure of carbon dioxide $(PCO_2)$ is higher in the body cells $(45 \; mm \; Hg)$ compared to the blood capillary $(40 \; mm \; Hg)$.This concentration gradient facilitates the diffusion of $CO_2$ from the body cells into the blood capillary,which is the process of releasing $CO_2$ from the cell.

The low partial pressure of oxygen $(PO_2)$ in the body cells results in:
