Document Summary
Compartment advantage: separation of biological processes that may conflict with one another; for example, protein synthesis vs protein degradation or lysosome acidity vs respective cell ph. Compartment disadvantage: barriers can make movement between comparments difficult; transport. Mechanical properties: give shape, strength, and flexibility while also serving as a glue : functional compartments of the body. Cranial cavity (skull), thoracic cavity (spine, ribs, diaphragm where heart is in pericardial sac and lungs are in pleural sacs), abdominopelvic cavity (peritoneum lines all abdomen but kidneys lie outside of abdominal cavity between peritoneum and the back) Lumen: interior of any hollow organ, which can be filled with air or fluid (fully or partially) o.

Extracellular fluid can be divided into plasma (fluid portion of blood which is in circular system) and interstitial fluid (which lies between circulatory system and cells: biological membranes.
