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

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/bodysystems/immunesystem/

What is an ORGANIC COMPOUND? A compound which contains: HYDROGEN OXYGEN PHOSPHORUS NITROGEN OR SULFUR CARBON Example: GLUCOSE C6H12O6

Lets Practice! How many of the following are ORGANIC COMPOUNDS? Compound: NaCl  Common Name: Table Salt  Compound: H2O  Common Name: Water  Compound: C10H20O Common Name: Menthol  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 42

Compound: NaCl  Common Name: Table Salt  Compound: H2O  Common Name: Water  Compound: C10H20O Common Name: Menthol  Compound: CF4 Common Name: Carbon Tetraflouride Compound: C8H10N4O2 Common Name: Caffeine  Compound: NH4 Common Name: Ammonia  Compound: C13H18O Common Name: Ibuprofen Compound: C19H16O4 Common Name: Warfarin

Organic compound chain made of small units called SUGARS! 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
