1 Human Body Systems

2 Organization of The Body The eleven organ systems of the human body work together to maintain homeostasis Homeostasis – process which organisms maintain a relatively stable internal environment

9 Nervous System Brain, Spinal cord, periperal nerves Function: Coordinates the body’s response to changes in its internal and external environments

11 Integumentary System Skin, hair, nails, sweat and oil glands Function: Serves as a barrier against infection and injury; helps to regulate body temperature; provides protection against ultraviolet radiation from the sun

13 Respiratory System Nose, pharynx, larynx, trachea, bronchi, bronchiales, lungs Function: Provides oxygen needed for cellular respiration and remove excess carbon dioxide from the body

15 Digestive System Mouth, pharynx, esophagus, stomach, small and large intestine Function: Converts foods into simpler molecules that can be used by the cells of the body; absorbs food

17 Excretory System Skin, lungs, kidneys, ureters, urinary bladder, urethra Function: Eliminates waste products of metabolism from the body; maintains homeostasis

19 Skeletal System Bones, cartilage, ligaments, tendons Function: Supports the body; protects internal organs; allows movement; stores mineral reserves; provides a site for blood cell formation

21 Muscular System Skeletal muscle, smooth muscle, cardiac muscle Function: Works with skeletal system to produce voluntary movement; helps to circulate blood and move food through the digestive system

23 Circulatory System Heart, Blood vessels, blood Function: Brings oxygen, nutrients, and hormones to cells; fights infection; regulates body temperature

25 Endocrine System Hypothalamus, pituitary, thyroid, parathyroids, adrenals, pancreas, ovaries(in females), testes (in males) Function: Controls growth, development, metabolism, and reproduction

27 Reproductive System Testes, epididymis, vas deferens, urethra, and penis (in males); Ovaries, fallopian tubes, uterus, vagina (in females). Produces reproductive cells; in females, nurtures and protects developing embryo

28 Respiratory SystemDigestive SystemExcretory System Endocrine SystemReproductive SystemLymphatic System Section 35-1 Figure 35-2 Human Organ Systems Part 2

29 Lymphatic System White blood cells, thymus, spleen, lymph nodes, lymph vessels Helps protect the body from disease; collects fluid lost from blood vessels and returns the fluid to the circulatory system.
