Human Body Organ Systems
� The Human body has 11 organ systems – cardiovascular (circulatory), digestive, endocrine, excretory (urinary), immune(lymphatic), integumentary, muscular, nervous, reproductive, respiratory, and skeletal. � Let’s review what we know about them!
Cardiovascular (Circulatory) System � Function › Carries oxygen and food to cells › Carries carbon dioxide away from cells › Transports nutrients, chemical messengers, gases, and wastes in the blood � Organs/Structure › Heart › Blood vessels
Respiratory System � Function �Adds oxygen to the blood �Removes Carbon Dioxide from the blood � Organs/Structures › › › Mouth Nose Trachea Bronchi lungs
Digestive System � Function › Breaks down food into units that can be absorbed by the body �Used by the body’s cells for energy � Organs/Structures › › Mouth Esophagus Stomach Intestines
Endocrine System �Function �Controls cell function with hormones: �Growth �Development �Metabolism �Reproduction �Organs/Structures �pituitary gland �Thyroid �thymus
Urinary (Excretory) System � Function › Removes waste from the body › Maintains body fluid volume, p. H and electrolyte levels � Organs/Structures › Kidney › bladder
Lymphatic (immune) System � Function › Protects the body from disease � Organs/Structures › White blood cells › Spleen › Lymph nodes
Integumentary System � Function › Provides a protective barrier for the body › Contains sensory receptors for pain, touch and temperature � Organs/Structures › › Skin Hair Nails Sweat and Oil Glands
Muscular System � Function › Works with skeletal system to produce movement › Moves bones and maintains structure � Organs/Structures › Skeletal muscles › Smooth muscles › Tendons
Skeletal System � Function › Supports the body › Works with muscular system to move the body › Protects major organs � Organs/Structures › Bones › Cartilage › Ligaments
Nervous System � Function › Controls cell function with electrical signals � Organs/Structures › Brain › Spinal cord › Nerves
Reproductive System � Function › Produces reproductive cells (gametes) › Responsible for producing offspring › Female organs provide environment for development of fetus
