Tissue repair depends . on the type of tissue damaged and the severity of the injury. .. Regeneration. : replacement of destroyed tissue with the same kind of tissue.. Fibrosis. The terminal end of an arteriole tapers toward the capillary junction to form a . single metarteriole. .. At the metarteriole-capillary junction, the distal most muscle cell forms the . . precapillary sphincter. Does your GI tract absorb into blood all nutrients? ions? water?. Now imagine that you drink water: 1 glass, 2, 3, 4, 5 glasses (1L). . Does the additional 1 liter of water stay inside . the blood vessels (18% increase from 5.5L)?. Mike Clark, M.D.. Lymphatic System. Composed of . lymphoid cells, tissues, organs, and vessels. The function of the lymphatic system is to . (1) fight infection (2) carry lipids absorbed from the GI tract to the bloodstream and (3) return fluids and plasma proteins that escaped from the bloodstream back to the bloodstream . -Consists of: Lymph, lymph vessels, lymph nodes and lymphatic tissue. -System works in conjunction with the circulatory system to remove waste and excess fluids from the tissues. -Lymph-a thin watery fluid composed of intercellular and interstitial fluid which forms when plasma diffuses into the tissue spaces. .

In the human . heart. there is one . atrium. and one . ventricle. for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: . blood vascular system. is composed of the following structures:. The . heart,. an organ whose function is to pump the blood.. The . arteries,. a series of efferent vessels that become smaller as they . _The wall of a segment of capillarity may be formed by a single endothelial cell. . _Only tunica intimae is present ,which typically consist of the endothelium, its basal lamina and an in complete layer of cells surrounding the capillary, the pericytes. .
