Document Summary

Male vs female: females have less because they have more fat store. Extracellular compartment interstitial fluid (isf) or intercellular fluid: fills the spaces between most cells of the body. Transcellular fluid (secretions eg. pericardial, synovial, etc) A. filtration: from high to low pressure. B. diffusion: movement of electrolytes or solutes. C. osmosis: movement of water from high to low. Low to high concentration (of blood, not water) Edema: excessive amount of fluid in the interstitial compartment. May be localized or throughout the body. Pushes cells apart to increase tissue size. Ascites: collection of fluid in abdominal area. Caused by higher blood pressure or increased blood volume. Forces increased fluid out of capillaries into tissue. Increased vascular volume: increased solutes, water comes in, bv goes up. Plasma proteins exert the osmotic force needed to pull fluid back into the capillary from the tissue spaces. Lymph nodes near arteries and veins, transport waste. Lymphadenopathy: swelling from fluid not being able to drain.
