Document Summary

Movement of the body > skeletal muscles attached to bones responsible for body movement (walking, running, chewing) Maintenance of posture > skeletal muscles maintain tone, keeps us sitting/standing erect. Respiration > skeletal muscles of thorax carry out respiratory movements. Production of body heat > skeletal muscles contract, give off heat as by-product, maintains body temp. Communication > skeletal muscles involved in speaking, writing, typing, gesturing, smiling. Constriction of organs and vessels > contraction of smooth muscles in walls of eternal organs/vessels cause structures to constrict. Propels/mixes food and water in digestive tract, removes materials from organs, regulates blood flow through vessels. Contraction of the heart > contraction of cardiac muscles causes heart to beat, propelling blood to parts of the body. Causes structures that its attached to to move or increase pressure inside a hollow organ/vessel. Shortens forcefully, lengthens passively (other forces such as gravity, contraction of opposing muscle, pressure of fluid in hollow organ cause it to lengthen)
