  • Respiratory
  • Immune
  • Digestive
  • Urinary
  • Hormonal
  • Reproductive

3
For each body system, it is important that you
understand its functions and structures.
  • Function- what does it do or its purpose???
  • Structure what is it made up of ???

For example, what are the functions and
structures of the following?
4
The Skeletal System
  • Functions
  • Movement
  • Support
  • Protection

Structures 1. 206 Bones
5
Fun Important Facts
  • The femur is the longest and strongest bone in
    the body
  • The most common broken bone is the clavicle

The Muscular System
  • Functions
  • Movement

    maximus
  • Eye muscles are the busiest (they move over
    100,000 times a day)

9
The Nervous System
  • Functions
  • Controls everything you do
  • Sends information through nerves
  • Divisions of the Nervous System
  • Brain and Spinal Cord (Central Nervous System)
  • 2. Nerves (The Peripheral Nervous System)

10

Cerebellum Balance and movement Frontal Lobe
controls, mood, motivation, aggression Parietal
Lobe Controls sensory information Occipital
Controls Vision Temporal-controls sense of smell,
hearing, memory, thought, and judgment.

  • Functions
  • Breathing
  • Gets oxygen to the cells

Structures Nose (warms air) Pharynx (upper
throat) Larynx (voice box) Trachea
(windpipe) Bronchi (tubes that bring air to
lungs) Lungs (exchange air) Diaphragm (muscle
that separates lungs from

  • A drop of Blood has 250 million red blood cells.

NY to LA is about 3,000 miles. So you could drive
there and back 12 times.
80,000 miles 3 times around the earth
18
4 blood types A, B, AB, and O
Type You Can Give Blood To You Can Receive Blood From
A A  AB A  A-  O  O-
O O  A  B  AB O  O-
B B  AB B  B-  O  O-

AB- AB  AB- AB-  A-  B-  O-
19
The Hormonal System
  • Functions
  • Regulates body
  • Secretes hormones
  • Structures
  • Pituitary Gland (controls growth)
  • Thyroid Gland (controls metabolism)
  • Adrenal Glands (produces adrenaline)
  • Pancreas (Secretes insulin)
  • Ovaries (produce estrogen)
  • Testes (produce testosterone)

20
Fun Important Facts

Your blood goes through your kidneys 400 times a
day
23
The Digestive System
  • Functions

  • Eliminates waste (poop ?)
  • Structures
  • 1.Mouth (breaks down food)
  • 2 Salivary Glands (Secretes saliva)
  • 3 Tongue (prepares food to be swallowed)
  • 4 Esophagus (tube food passes through)
  • 5 Stomach (food is stored and mixed with juices)
  • 6 Small Intestine (absorbs the food)
  • 7 Large Intestine (removes water from food and
    eliminates waste)

  • The small intestine is 21 feet long
  • We produce 3 pints of Saliva every day

  • Functions
  • Kills and Fights off diseases
  • Helps keep body healthy and strong
  • Structures
  • Tonsils (catch incoming germs)
  • Lymph Nodes (filter foreign objects)
