System Title: Integumentary Generalized Function: Organs Specific Function skin Hold our organs in. Protect our organs from infections and bacteria. Waterproofs the body, protects deeper tissues, helps regulate body temp. and alerts us what happens at the body surface. System Title: Skeletal System Generalized Function: Protects and supports body organs; provides a framework the muscles; used to cause movement; blood cells are formed with the bones; stores minerals. Organs Specific Function 1. Joints 1. Provide movement in our bones. 2. Bones 2. Allow us to maintain posture. System Title: Cardiovascular Generalized Function: Carries oxygen, nutrients, hormones, and other substances to and from the tissue cells where exchanges are made. Organs Heart Blood Vessels Specific Function System Title: A “blood pump” propelling blood through the blood vessels to all the body tissues. Carry the nutrients, blood, and oxygen through the body Digestive System Generalized Function: To break down ingested food and deliver products to blood to disperse to body cells, also to rid of unnecessary waste. Organs Specific Function Oral Cavity (mouth) Food is broken down and enters digestive tract. Esophagus A passageway that conducts food to the stomach. Stomach A storage tank for food and site for breakdown. Small Intestine Major digestive organ. Prepares useable food for the cells to take. Large Intestine Dries out indigestible food residue by absorbing water and to eliminate as feces. Rectum Anus System Title: Endocrine Generalized Function: Controls body activities, produces hormones and releases into the blood. Organs Pituitary thyroid Parathyroids Adrenals Thymus Pancreas Pineal Ovaries Testes System Title: Specific Function Regulation of the gonads, thyroid, adrenal cortex, water balance, and lactation. Raises blood calcium level Increase blood glucose Programs T-cells Reduces blood glucose Involved in rhythmic activities Stimulate uterine lining growth Supports sperm formation Nervous System Generalized Function: Controls how the body receives and processes stimuli. Fast-acting control system of the body. Responds to internal and external changes by activating appropriate muscles and glands. Organs 1. Brain 2. Sensory receptors 3. Spinal cord Specific Function 1. The brain is the nervous system’s center where all of the information is gathered to in order for the body to respond to the internal and external environment. 2. The sensory receptors are where the stimuli are received. 3. The spinal cord detects and sends messages (via electrical signals called nerve impulses) to the central nervous system (brain and spinal cord.) System Title: Urinary Generalized Function: Removes the nitrogen containing waste from the blood in the urine. Organs Bladder Specific Function A smooth collapsible muscular sack that temporarily holds urine. Kidneys clean the blood and adjust its composition Holds the urethra or “pee hole”. The urethra is a thin wall tube that carries urine. Kidney(s) Penis/vagina System Title: Muscular System Generalized Function: To contract or shorten with reactions and commands (similar to “moving bones”) Organs 1. Skeletal muscles 2. Cardiac muscle 3. Smooth muscle Specific Function 1. When they contract you’re able to walk, leap, jump and smile, etc. 2. Pumps blood and oxygen 3. Found in the walls visceral organs (the stomach, urinary bladder, and respiratory passages) System Title: Lymphatic System Generalized Function: Works hand in hand with the cardiovascular system. Returns fluids leaked from blood to the vessels so that blood circulates. Organs 1. Lymphatic vessel Specific Function 1. Picks up excess tissue fluid called lymph, and return it to the bloodstream 2.Lymph nodes 2. remove foreign material from the body 3. Cleanse the blood and house the cells involved with immunity 3. Lymphoid organs (spleen, thymus, tonsils, Peyer’s patches) System Title: Respiratory System Generalized Function: Keeps blood constantly supplied with oxygen and removes carbon dioxide . Organs External Nares Nasal Cavity Pharynx Larynx Trachea Primary Bronchi Lungs Specific Function During breathing, air enters the nose through the external nares, or nostrils. The interior of the nose consist of the nasal cavity. The pharynx is a muscular passageway for food and air. The larynx routes air and food into the proper channels. The trachea is a windpipe. The primary bronchi are within the lungs and are direct routes to the air sacs. The lungs are mostly air spaces. The diaphragm contracts and the size of the thoracic cavity increases. Diaphragm System Title: Reproductive system Generalized Function: To produce offspring Organs Specific Function Testes Produces sperm and male hormones. Scrotum Sac of skin at root of penis. Provides testes w/ appropriate temperature and enclosure. Delivers sperm. Penis Ovaries Makes eggs (ova) and produces female hormones. Fallopian Tubes Carries egg from ovaries to uterine wall and holds ovaries in place. Uterus Provides site for development of fetus until fertilization has occurred. Vagina Provides passageway for delivery of a an infant and for menstrual flow to leave the body.
