Make this data table twice in your science notebook. It will take TWO FULL PAGES so allow yourself enough room
THE SKELETAL SYSTEM Major Organs: Bones, cartilage, tendons and ligaments.
The Skeletal System Protects, supports, allows movement, produces blood cells & stores minerals
Factoids: Skeletal • The human hand has 27 bones; your face has 14! • The longest bone in your body? Your thigh bone, the femur -- it's about 1/4 of your height. The smallest is the stirrup bone in the ear which can measure 1/10 of an inch. • You have over 230 moveable and semi-moveable joints in your body
THE MUSCULAR SYSTEM Major Organs:Skeletal muscles and smooth muscles throughout the body.
The Muscular System Allows body movement & maintains posture
Factoids: Muscular • You have over 30 facial muscles which create looks like surprise, happiness, sadness, and frowning. • Eye muscles are the busiest muscles in the body. Scientists estimate they may move more than 100,000 times a day! • The largest muscle in the body is the gluteus maximus muscle in the buttocks.
THE DIGESTIVE SYSTEM Major Organs:Mouth, esophagus, stomach, small and large intestines
The Digestive System Allows the body to break down food and nutrients!
Factoids: Digestive • HOW LONG ARE YOUR INTESTINES? At least 25 feet in an adult. Be glad you're not a full-grown horse -- their coiled-up intestines are 89 feet long! • Chewing food takes from 5-30 seconds • Swallowing takes about 10 seconds • Food sloshing in the stomach can last 3-4 hours • It takes 3 hours for food to move through the intestine
THE CIRCULATORY SYSTEM Major Organs:Heart, blood vessels and blood.
The Circulatory System Transports nutrients wastes, and other materials and plays a role in the immune system
Factoids: Circulatory • The body of an adult contains over 60,000 miles of blood vessels! • An adult's heart pumps nearly 4000 gallons of blood each day! • Your heart beats some 30 million times a year! • The average three-year-old has two pints of blood in their body; the average adult at least five times more! • A "heartbeat" is really the sound of the valves in the heart closing as they push blood through its chambers.
THE RESPIRATORY SYSTEM Major Organs:Nose, trachea, diaphragm and lungs.
The Respiratory Systems oxygen Exchanges & carbon dioxide air between blood &
Factoids: Respiratory • Your lungs contain almost 1500 miles of airways and over 300 million alveoli. • Every minute you breathe in 13 pints of air.
THE EXCRETORY SYSTEM Major Organs:Kidneys, ureters, bladder and urethra.
The Excretory System Removes solid & liquid wastes
Factoids: Excretory • Ever eat kidney beans? They were named after your kidneys which are a similar shape and color! • Your kidneys have about a million structures that filter out liquids and wastes. • About 440 gallons of blood flow through the kidneys each and every day!
THE NERVOUS SYSTEM Major Organs:Brain, spinal cord and peripheral nerves.
The Nervous System Detects sensation & controls most functions
THE ENDOCRINE SYSTEM Major Organs:Many glands exist in the body that secrete endocrine hormones. Among these are the hypothalamus, pituitary, thyroid, pancreas and adrenal glands.
THE ENDOCRINE SYSTEM Regulates metabolism, reproduction & other functions
Factoids: Endocrine • Imagine your body without glands. You'd be without all the ooze, sweat, mucus, chemicals and juices in your body which make your body home. • For girls, puberty generally begins sometime between ages 9-13 and for boys, ages 10-15!
THE IMMUNE SYSTEM Major Organs:Lymph, lymph nodes and vessels, white blood cells, T- and B- cells.
The Immune System Controls the immune response & fights disease
The Integumentary System (Skin) Protects, Regulates Temperature & Prevents Water loss
Factoids: Integumentary • As an adult, you may have more than 20 square feet of skin -- about the size of a blanket. • You are likely to shed some 40 pounds of skin in a lifetime. • Right now there are over a million dust mites, microscopic critters invisible to the naked eye, on your mattress and pillow, chomping on the dead skin cells that fell off you last night!
