Fluid connective tissue
blood and lymph are connective tissue fluid matrix that surrounds cells includes many suspended proteins that do not form insoluble fibers
- in blood, watery matrix is called plasma
- plasma — contains formed elements — blood cells and fragments of cells
- RBC
- WBC
- platelets
- plasma — contains formed elements — blood cells and fragments of cells
- body has a lot of extracellular fluid, includes three subdivisions — plasma, interstitial fluid, lymph
- in blood, watery matrix is called plasma
Fluid tissue transport systems
- plasma — confined to vessels of cardiovascular system
- arteries — carry blood away from heart and into tissues of body
- in those tissues, blood pressure forces water and small solutes out of bloodstream across walls of capillaries (smallest blood vessel)
- remaining blood flows from capillaries into veins that return to heart
- lymph — forms as interstitial fluid enters lymphatic vessels monitored by immune system so lymph transported by lymphatic (lymphoid) system lymphatic vessels return lymph to large veins near heart (venous system)
