Filtration is involved in the formation of tissue fluid because
the wall of blood capillary is selectively permeable and acts as a filter.
The hydrostatic pressure of the blood is lower than the tissue fluid.
blood cells and plasma proteins block the pores on the wall of blood capillary.
oxygen and nutrients can diffuse across the wall of blood capillary.
Arteries, except for the pulmonary artery, carry
