Document Summary
Heart, blood vessels, lymphatics, blood, lymph, associated organs. Delivery of oxygen (acquired in the lungs) Pick up of nutrients from the gi tract, delivery to the body"s cells. Pick up hormones from endocrine glands, deliver to target cells. Waste removal from cells, delivery to waste disposal organs/systems. Intracellular fluid the water within cells (2/3 of total volume) Extracellular fluid the water that surrounds cells (1/3 of total volume) Interstitial fluid the water around cells, (not in the vascular system) Blood plasma the water component of blood. Capillaries = permeable water can leak out. At the arterial side of the capillary bed, blood pressure is higher than tissue (hydrostatic pressure) = water and proteins leak out. Certain substances can not move across the capillary ex:albumin. At venule side of capillary the higher concentration of these substances draws some of the water back into the capillary. Not all the water gets back into the capillary (~10% remains)
