Make this data table twice in your science notebook. It will take TWO FULL PAGES so allow yourself enough room

major organs bones cartilage tendons and ligaments

THE SKELETAL SYSTEM

Major Organs:

Bones, cartilage, tendons and ligaments.

slide4

The Skeletal System

Protects,

supports,

allows movement,

produces blood cells

&

stores minerals

factoids skeletal
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
slide7

The Muscular System

Allows body movement

&

maintains posture

factoids muscular
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.
slide10

The Digestive System

Allows the body

to break down

food and

nutrients!

factoids digestive
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
slide13

The Circulatory System

Transports nutrients

wastes, and other materials

and plays a role in the

immune system

factoids circulatory
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.
slide16

The Respiratory Systems

oxygen

Exchanges

&

carbon dioxide

air

between

blood

&

factoids respiratory
Factoids: Respiratory
  • Your lungs contain almost 1500 miles of airways and over 300 million alveoli.
  • Every minute you breathe in 13 pints of air.
slide19

The Excretory System

Removes

solid

&

liquid

wastes

factoids excretory
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!
slide22

The Nervous System

Detects

sensation

&

controls

most

functions

slide23

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.

slide24

THE ENDOCRINE SYSTEM

Regulates

metabolism,

reproduction

&

other

functions

factoids endocrine
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!
slide27

The Immune System

Controls the

immune response

&

fights disease

slide29

The Integumentary System

(Skin)

Protects,

Regulates

Temperature

&

Prevents

Water loss

factoids integumentary
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!
