The Skeletal System Essay examples -- Basic Pathology

The skeletal system includes the osseous tissues of the body and the connective tissues that change or interconnect the individual hit the books. The oculus sinister is a dynamic tissue. end-to-end the lifespan, bone adjusts to the physiologic and mechanical demands placed on it by the processes of gain and remodeling. tog up serves the organism at multiple levels As a system, finger cymbals permit the organism to locomote effectively and to maintain posture by bearing loads without deformation, by providing rigid attachment sites for muscles and acting as a system of levers to amplify small movements. As an organ, grind away entertain the viscera and house the hemopoietic tissue (red marrow). As a tissue, bones serve as a reservoir of readily mobilizable calcium, an ion vital for many another(prenominal) metabolic processes including cell motility, excitability, secretion, phagocytosis, intermediary metabolism, respiration, and reproduction.Bones (or osseous material) serve a number of diverse purposes in the human anatomy. In addition to providing structure, leverage, protection, and game for the organs of the body, bones also house marrow, which produces blood cells. Within the bones are also stored the calcium deposits which the body may access, via resorption, when needed. Additionally, bones detoxicate the system, by removing heavy metals, such as lead and arsenic, as headspring as other toxins, from the bloodstream. The skeletal system provides structural support for the inherent body. Individual bones or groups of bones provide a textile for the attachment of soft tissue and organs. Delicate tissues and organs are lots surrounded by skeletal elements. The ribs protect the heart and lungs, the skull encloses the brain, the vertebrae shield the spinal anesthesia cord, and the pelvis ... ...& J.W.
