Title: Human Body Systems


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

Nervous System
  • Brain, Spinal cord, periperal nerves
  • Function Coordinates the bodys 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

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

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

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

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.
