3 1. Integumentary System. • Components = skin, hair, nails, and sweat glands. The function of this system is that it covers and protects the body. 2. Skeletal System. • Components = bones, cartilage and ligaments. This system supports and protects the body; muscles attached to bones; provides calcium storage; site of blood cell formation. 3. Muscular System. • Components = skeletal muscle, cardiac muscle, and smooth muscle. This system moves parts of the skeleton, locomotion; pumps blood; aids movement of internal materials.

3Integumentary System.Components= skin, hair, nails, and sweat glands.The function of this system is that it covers and protects the body.2. Skeletal System.Components= bones, cartilage and ligaments. This system supports and protects the body; muscles attached to bones; provides calcium storage; site of blood cell formation.3. Muscular System.Components= skeletal muscle, cardiac muscle, and smooth muscle.This system moves parts of the skeleton, locomotion; pumps blood; aids movement of internal materials. The Body Organ Systems

3 cont. 4. Nervous SystemComponents= nerves and sense of organs, brain and spinal cord.This system receives stimuli from external and internal environments, conducts impulses and integrates activities of other systems. 5. Endocrine System Components= Pituitary gland, adrenal gland, thyroid gland, hypothalamus glad, pineal gland, kidney, pancreas, ovaries, testes, and other ductless glands.This system regulates body chemistry and many body functions.6. Circulatory SystemComponents= Heart, blood vessels, blood; lymph and lymph structures. This system transports materials from one part of the body to another, and defends body against disease.

3 cont.7. Respiratory SystemComponents= Lungs and air passageways.This system exchanges gases between the blood and external environment. 8. Digestive SystemComponents= mouth, esophagus, intestines, liver, and pancreas. This system ingests and digests foods, and absorbs them into the blood.9. Urinary SystemComponents= Kidney, bladder, and associated ductsThis system excretes metabolic wastes, and removes substances present in excess from the blood.

3 cont.10. Reproductive SystemComponents= Testes, ovaries, and associated structures. This system is the system of reproduction, which provides for continuation of the species. 11. Lymphatic SystemComponents= spleen, thymus, tonsils, and lymph nodes.This system defends against infection and disease.

4 Characteristics of Human LifeLiving things are composed of cells.Living things have different levels of organization.Livings things use energy.Living things respond to their environment.Living things growLiving things reproduce.Living things adapt to their environment.
