Document Summary
Force and transform them into motions that animals can make. Lifeless shell that is located outside the organisms body. Can be modified to function as tools or weapons. Molting or ecdysis: organism is very weak and vulnerable at this time. Bone: store calcium and are important in maintaining homeostatic levels of calcium in the blood. As muscle changes due to physical stress bone strengthens to accomodate. When trapped in matrix of collagen fibers = osteoclast. Remodeling process = breaking down and rebuilding. Human skeleton is replaced every 10 years. Osteoporosis: skeleton broken down faster then can be rebuilt. Occurs in older women due to decrease of estrogen. Connect bones and limit movement at joints. Rheumatoid arthritis: synovial membrane thickens and becomes inflamed. Generate mechanical force and motion necessary for. Flight muscle contraction = 1000 contractions per second. Tiny air filled tubes that carry oxygen to muscle cell. Higher temp = inc rate of atp synth.
