Capillary Exchange

Capillary Exchange

Exchange of substances between blood capillaries and the interstitial fluid of tissues is regulated by hydrostatic pressure and osmotic pressure. Fluid leaves the blood capillaries at the arteriolar end of a capillaries. About 90% of this fluid reenters capillaries at their venular ends. The remaining fluid is returned to the blood through lymphatic system.

Histology Animations

Growth of cartilage is either interstitial growth, resulting from the mitotic division and reactivation of preexisting chondrocytes, or more commonly appositional growth, resulting from the differentiation of perichondrial cells.In a growing bone, metaphysis includes a cartilaginous epiphyseal plate that allows diaphysis to grow in length. The epiphyseal plate disappears in adults leaving a bony epiphyseal line. Hence bone does not grow in length occur in adults. Bone can grow in thickness only by appositional growth resulting from the differentiation of periosteal cells. Continue reading the full post to view the animation.
