BODY SYSTEMS SKELETAL SYSTEM Click the picture for a short video FUNCTION – “The Frame” Support Movement Protection of internal organs Bones store calcium Bone marrow produces red blood cells MAJOR ORGANS Bones Cartilage – flexible connective tissue. Tendons – attaches muscles to bones. Ligaments – connects bones to each other. TISSUES Connective tissue (cartilage, bone, ligaments, tendons) Spongy bone tissue (Bone marrow) CELLS Oseocytes (bone cells) MUSCULAR SYSTEM Click the picture for a short video FUNCTION – “Bundles of Energy” Movement Specialized muscles are part of most body systems and aid in functions such as circulation and digestion MAJOR ORGANS Muscles TISSUES Muscle tissue Skeletal muscle – muscles used for voluntary movement Smooth muscle – muscles used for involuntary movement in hollow organs Cardiac muscle – heart muscle CELLS Muscle cells CIRCULATORY SYSTEM CARDIOVASCULAR Cardiovascular System Cardio/Cardiac means “heart” CIRCULATORY SYSTEM CARDIOVASCULAR Click the picture for a short video about the CARDIOVASCULAR (CIRCULATORY) STSYTEM Click here for more information about the circulatory system FUNCTION – “The Life Pump” Transports different materials needed to live throughout the body, including: Oxygen Carbon dioxide (CO2) Waste materials Nutrients MAJOR ORGANS Heart – provides continuous blood circulation MAJOR ORGANS Blood vessels – carries blood Arteries – carries blood away from heart Veins – carries blood toward the heart Capillaries – blood vessels that form a network between arteries and veins TISSUES Blood is a fluid connective tissue Smooth muscle tissue (walls of blood vessels) Cardiac (heart) muscle CELLS Cardiac (heart) cells Blood cells Red blood cells carry oxygen White blood cells help fight infection Discovery Education http://app.discoveryeducation.com/s earch?Ntt=circulatory&N=18342&N= 4294924486 RESPIRATORY SYSTEM It is made up of the organs in your body that help you breathe. Respiration = breathing. Click the picture for a short video FUNCTION – “The Air Bags” Exchanges oxygen (O2) and carbon dioxide (CO2) gases Carbon dioxide is removed from blood sent to the lungs Oxygen is added to the blood leaving the lungs Allows speech MAJOR ORGANS •Trachea •Lungs •Diaphragm •Bronchus •Bronchioles •Alveoli OTHER STRUCTURES Nose / Nasal Cavity Mouth Larynx Pharynx TISSUES Skeletal muscle tissue (diaphragm) Epithelial lining (lining of nose and mouth, trachea, bronchus, bronchioles, alveoli) CELLS Epithelial cells make up almost all of the tissues in the respiratory system IMMUNE SYSTEM Click diagram for more information FUNCTION –”The Disease Warriors” Protects the body from disease http://www.youtube.com/watch?v= 6uwVhn-APsQ (You may have to log into www.teachersdomain.org to use interactive link.) MAJOR ORGANS TISSUES Lymph tissue CELLS White Blood Cells DIGESTIVE SYSTEM Click the picture for a short video Click here for more information on digestion FUNCTION – “The Food Factory” Breaks down food into a form the body can use Involves physical and chemical changes MAJOR ORGANS Mouth Esophagus Stomach Liver Gall Bladder Pancreas Intestines TISSUES and CELLS Smooth muscle tissue Smooth muscle cells http://www.brainpop.com/health/bo dysystems/immunesystem/ What is an ORGANIC COMPOUND? A compound which contains: CARBON HYDROGEN OXYGEN PHOSPHORUS NITROGEN OR SULFUR Example: GLUCOSE C6H12O6 Lets Practice! How many of the following are ORGANIC COMPOUNDS? Compound: NaCl Common Name: Table Salt Compound: C10H20O Common Name: Menthol Compound: H2O Common Name: Water Compound: CH4 Common Name: Methane Compound: C8H10N4O2 Common Name: Caffeine Compound: NH4 Common Name: Ammonia Compound: C13H18O Common Name: Ibuprofen Compound: C19H16O4 Common Name: Warfarin Compound: NaCl Common Name: Table Salt Compound: C10H20O Common Name: Menthol Compound: H2O Common Name: Water Compound: CF4 Common Name: Carbon Tetraflouride Compound: C8H10N4O2 Common Name: Caffeine Compound: C13H18O Common Name: Ibuprofen Compound: NH4 Common Name: Ammonia Compound: C19H16O4 Common Name: Warfarin SUGAR CARBOHYDRATE Organic compound chain made of small units called SUGARS! DIGESTION CARBOHYDRATE SUGAR ENERGY EXCRETORY SYSTEM Click the picture for a short video The Excretory System Also known as the Urinary System FUNCTION – “The Garbage Collector” Removes wastes from blood Allows wastes to leave the body MAJOR ORGANS Kidneys Ureter Bladder Urethra Click diagram for more information TISSUES Nephrons (tissue in kidneys) Smooth muscle CELLS Smooth muscle cells Homeostasis Excretion maintains homeostasis by keeping the body’s internal environment stable and free of harmful levels of chemicals. Why is the Excretory System Important? The major organs of the excretory system eliminate urea, water, and other wastes from the body. INTEGUMENTARY SYSTEM Click diagram for more information For more information, click here. FUNCTION – “The Armor” Covers and protects internal structures Regulates body temperature Keeps body from losing water MAJOR ORGANS Skin Sweat glands Hair Nails TISSUES Epidermal tissue Dermal tissue CELLS Epidermal (skin) cells NERVOUS SYSTEM Click diagram for more information FUNCTION – “The Control Center” Sends throughout the body Controls voluntary and involuntary functions MAJOR ORGANS Brain Spinal cord Nerves TISSUES Nerve tissue CELLS Neurons (nerve cells) Axons dendrites ENDOCRINE SYSTEM Click diagram for more information FUNCTIONS – “The Chemical Coordinator” Produces hormones that regulates body functions that happen slowly, such as growth MAJOR ORGANS Glands Adrenal Pituitary Thyroid Thymus Pancreas Reproductive glands (ovaries and testes) Hormones and Receptors Hormones are chemical messengers that interact with receptors. TISSUES Tissues that secrete hormones CELLS Gland cells secrete hormones “Target cells” receive the hormones REPRODUCTIVE SYSTEM FUNCTION – “The Baby Factory” Produces offspring MAJOR ORGANS Ovaries Uterus Testes TISSUES Specialized tissues for egg and sperm production CELLS Sex cells (gametes) Eggs Sperm
