venous capillary

By lowering the pH levels in the venous capillaries, oxygen unbinds from blood hemoglobin.

Gas is diffuses (in most cases) into the bladder through the venous capillaries, while the gases being taken away are diffused into the arterial capillaries.

Normally, pleural fluid is absorbed by pulmonary venous capillaries (80%-90%), with some of it also absorbed by pleural lymphatics.

Note that previously it was believed that at steady state the arterial capillaries filter fluid and the venous capillaries reabsorb it, as shown by the diagram.

And as he felt the suction and faint pricking, and knew it was drawing fresh blood from him and simultaneously discharging vitiated blood into his venous capillaries, he experienced a dreamy gratification.

This fluid returns through venous capillaries to the blood circulation through the force of osmosis in the venous blood; however, a portion of the fluid which contains proteins, cellular debris, bacteria, etc. must return through the lymphatic collection system to maintain tissue fluid balance.
