how many organ systems work together to maintain homeostasis?
Nervous system
structures: brain, spinal chord, peripheral nerves
Function: cordinates body's response to changes in its internal and external enviornmnets
Integumentary system
structures: skin, hair, nails, sweat, and oil glands
function: serves as a barrier against infection and injury; helps to regulate body temperature; probides protection against ultraviolet radiation from the sun
respiratory system
structure: nose, pharnyx, larnyx, trachea, bronchi, bronchioles, lungs

function: provides oxygen needed for cellular respiration and removes excess carbon dioxide from the body
digestive system
structures: mouth, pharnyx, esophagus, stomach, small and large intestines

function: converts food into simpler molecules that can be used by the cells of the body; absorbs food
excretory system
structures: skin, lungs, kidneys, ureters, urinary bladder, uretha,

function: eliminates waste products of metabolism from the body; maintains homeostasis
skeletal system
structures: bones, cartilage, ligaments, tedons

functions: supports the body; protects internal organs; allows movement; stores mineral reserves; provides site for blood cell formation
muscular system:
structures: skeletal muscle, smooth muscle, cardiac muscle

Function: works with skeletal system to produce voluntary movement; helps circulate blood and move food through the digestive system
circulatory system
structures: heart, blood vessels, blood

function: brings oxygen, nutrients, and hormones to cells; fights infection; regulates body temperature
endocrine system
stuctures: hypothalamus, pituitary, thyroid, parathyroids, adrenals, pancreas, ovaries (in females), testes (in males)

functions: controls growth, development, metabolism, and reproduction
reproduction system
structures: testes, epididymis, vas deferens, urethra, penis; ovaries, fallopian tubes, uterus, vagina

function: produces reproductive cells; in females, nutures and protects the developing embryo
lympatic system
structures: white blood cells, thymus, spleen, lymph nodes, lymph vessels

functions: helps protect the body from disease; collects fluid from lost from blood vessels and returns the fluid to the circulatory system
muscle tissue
the most abundant tissue in most animals, controls the internal movement of materials such as the circulatory system and food through the digestive system, also controls external movements of the entire body or parts of the body
epithelial tissue
tissue that covers the surface of the body and lines internal organs, glands are made from this tissue
connective system
holds organ and binds different parts of the body, provides support for the body, keeps walls of the heart flexible, but strong, and insulates and pads parts of the body
nervous tissue
recieves messages from the body's external and internal enviornments, analyzes the data, and directs the response
3 types of neurons
