Skeletal+System

__// ﻿Skeletal System //__
 * very thorough, especially how skeletal fits in with all the other body systems ~Mrs. Rohland **

The function is to provide a framework, and protective shields for softer tissues and act with muscles when body parts move.

The characteristics of life that are part of the system are movement and growth.

Organs found in the system are the bones because they provide points of attachment for muscles, protect and support softer tissue, house blood-producing cells, store inorganic salts, and form passageways for blood vessels and nerves. The axial skeleton which would consists of the skull, vertebral column, and the thoracic cage. This part of the skeleton lies on the midline which is a vertical line which would separate the body into two even parts. Your phalanges are the most distant bones from your trunk. Your humerus is superior to your phalanges, which means it is closer to your head. Your humerus is also proximal to your phalanges which means it is closer to your trunk.

Body Cavities- The skull protects the cranial cavity which includes the brain. The vertebral canal is protected by the spinal column. The thoracic cavity is well protected by your ribs and the sternum. Your pelvic cavity is protect by your pelvis. The cavity that is not well protected by the skeletal system is the abdominal cavity.

The Integumentary System- The Vitamin D that is in the skin helps in calcium absorption. The Lymphatic System- These cells which aid in the immune system come from the bone marrow. The Muscular System- The muscles pull the bones which cause movement. The Digestive System- Absorbing dietary calcium provides material for the bone matrix. The Nervous System- Pain receptors warn of trauma to the bones, and the bones help protect the brain and the spinal cord. The Respiratory System- The muscles and ribs work together in breathing. The Endocrine System- The hormones act on the bones to help regulate blood calcium levels. The Urinary System- The bones and the kidneys work together to help regulate blood calcium levels. The Cardiovascular System- The blood brings nutrients to the bone cells, and the bones help regulate plasma calcium levels which are important to heart function. The Reproductive System- The pelvis helps support the uterus during pregnancy and the bones provide a source of calcium during lactation.

Metabolism fits in the organ system because when you break a bone or fracture it it must create new tissue and the only way it can do that is if it has energy which you get from the break down of food from the digestive system.

Homeostasis fits into the skeletal system because it provides proper calcium levels in the blood.
