Digestive SystemGross and Cool Facts!
  • 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
  • Food drying up and hanging out in the large
    intestine can last 18 hours to 2 days!
  • Americans eat about 700 million pounds of peanut
    butter.
  • Americans eat over 2 billion pounds of chocolate
    a year.
  • In your lifetime, your digestive system may
    handle about 50 tons!!

Respiratory SystemGross and Cool Facts!
  • Your lungs contain almost 1500 miles of airways
    and over 300 million alveoli.
  • Every minute you breathe in 13 pints of air.
  • Plants are our partners in breathing. We breathe
    in air, use the oxygen in it, and release carbon
    dioxide. Plants take in carbon dioxide and
    release oxygen. Thank goodness!
  • People tend to get more colds in the winter
    because we're indoors more often and in close
    proximity to other people. When people sneeze,
    cough and even breathe -- germs go flying!

Menu
10
Circulatory SystemGross and Cool Facts!
  • 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.

11
Muscular SystemGross and Cool Facts!
  • 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.

Menu
12
Skeletal SystemGross and Cool Facts!
  • 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.
  • Did you know that humans and giraffes have the
    same number of bones in their necks? Giraffe neck
    vertebrae are just much, much longer!
  • You have over 230 moveable and semi-moveable
    joints in your body.

Introduction to the Body Systems
14
Organization in the Body
  • Cell--gt smallest unit of life Ex. Blood cell
  • Tissue--gt made of many similar cells Ex. Blood
    Tissue
  • Organ--gt made of many similar tissues Ex. Heart
  • Organ System--gt several organs working together
    Ex. Circulatory System

15
TYPES OF TISSUE
  • EPITHELIAL
  • NERVE
  • CONNECTIVE
  • MUSCLE
  • BLOOD
  • Protects other tissue
  • Sends/receives messages
  • Supports/protects body
  • Allows movement
  • Carries oxygen, food through body

17
Body Systems Overview
  • Digestive
  • Breaks down food into small bits for cells to use

18
Pathway of Digestion
1. MOUTH- Digestion begins, starches broken
down (saliva and teeth)
2. ESOPHAGUS Food passes through (peristalsis)
19
Pathway of Digestion
  • STOMACH
  • Chemical Mechanical digestion (proteins broken
    down)
  • SMALL INTESTINE
  • Most digestion happens, digestion is completed-
    find villi for absorbing nutrients

20
Pathway of Digestion
  • LARGE INTESTINE
  • Stores eliminates undigested food
  • ANUS
  • Solid waste passed out

21
Body Systems Overview
  • Respiratory
  • Lungs take in O2 which is combined w/ nutrients
    for energy

22
Respiratory System
  • Pathway of oxygen
  • 1. Mouth/ nose
  • 2. Trachea
  • 3. Two bronchial tubes
  • 4. Bronchi branches
  • 5. Air sacs
  • 6. Capillaries
  • Blood picks up OXYGEN in capillaries of air sacs
  • The waste CARBON DIOXIDE is dumped off

23
Path of Oxygen through the Respiratory System
24
Body Systems Overview
  • Circulatory
  • Blood transports oxygen from lungs to cell, and
    wastes from cell to lungs

25
Circulatory System
  • Pathway of Blood
  • Blood is pumped by the heart carried by 3 types
    of blood vessels
  • Arteries- carry blood away from heart (carries
    CO2)
  • Veins- carry blood to heart (carries O2)
  • Capillaries- tiny, thin walls so O2 and CO2 can
    pass through

26
Body Systems Overview
  • Nervous
  • Receiving and sending messages

27
Nervous System
  • Stimulus Response Pathway
  • Made of nerve cells (NEURONS)
  • 1. Senses send signals (stimulus) to brain
  • 2. Brain decides how to respond (response)
  • 3. Nerves carry response to proper part

28
Body Systems Overview
  • Excretory
  • Ridding body of wastes (water, heat, urine, CO2,
    salt)

29
Excretory System
  • LUNGS- excretes CO2, water, heat
  • SKIN- excretes water, salt, heat
  • KIDNEYS- excretes water, salt, urine
  • Organs of Excretion

30
Excretory System
  • ANUS/LARGE INTESTINE- gets rid of feces (s0lid
    waste)
  • Organ of elimination

31
Body Systems Overview
  • Reproductive
  • Sex cells combine to make offspring (sperm egg
    fertilization)

32
Body Systems Overview
  • Endocrine
  • Glands make and release chemical regulators into
    the blood hormones to respond to changes inside
    outside the body

33
Endocrine System
  • Pituitary- controls all other glands
  • Thyroid- regulates metabolism
  • Thymus- fights infection
  • Adrenals- fights body stress
  • Islets of Langerhans- Produces insulin to control
    blood sugar levels
  • Gonads/Testes- makes sex cells
  • GLANDS

34
Body Systems Overview
  • Muscular
  • Allows body to move
  • Muscles only contract (pull)- they dont push

35
Muscular System Diagram
36
Muscular System
  • Types of muscles
  • VOLUNTARY (skeletal)
  • Can control them
  • Are attached to bones
  • Work in pairs

37
Muscular System
  • Types of muscles
  • INVOLUNTARY (smooth)
  • Cant control them
  • Found in blood vessels, organs, digestive tract

38
Muscular System
  • Types of muscles
  • Cardiac (Heart)
  • Smooth, Involuntary

39
Body Systems Overview
  • Skeletal
  • Protects organs, allows movement, makes cells

40
Skeletal System
  • Joints
  • How do bones move?
  • 3 type of joints
  • Ball Socket- allows twisting (hips)
  • Hinge- move in one direction (elbow)
  • Slightly moveable- limited movement (vertebra
    ribs)

44
Skeletal System
  • Bones
  • Blood cells made in marrow- have calcium

45
Skeletal System
  • Cartilage
  • Softer, flexible bone

46
Skeletal System
  • Ligaments
  • Holds bone together at joints

47
Skeletal System
  • Tendons
  • Cordlike tissue that attaches muscle to bone
