The Circulatory System
4
The Circulatory System

• The circulatory system consists of the heart,
  arteries, veins and capillaries, and the blood.
  All of the other systems in the body rely on the
  circulatory system, except for the skeletal
  system.

5
What is the Circulatory System?

• The circulatory system carries blood throughout
  the body. The heart is the main control of the
  circulatory system. Without the heart, we would
  die. If the blood doesnt go throughout the body,
  the brain doesnt get the blood to function
  properly.

6
What Blood Does

• The blood transports oxygen, nutrients, wastes,
  and carbon dioxide throughout the body. When you
  breath oxygen, the oxygen goes down your trachea,
  which splits up into smaller tubes that end in
  tiny air sacs called alveoli. Since the walls of
  alveoli are only one cell thick, oxygen can
  diffuse through the walls into the capillaries.
  The capillaries get blood from the pulmonary
  arteries and transport the oxygen to the rest of
  the body through the blood. The capillaries also
  transport nutrients, carbon dioxide, and wastes
  to and from the body.

7
Capillaries

• The capillaries get blood from the pulmonary
  arteries and transport the oxygen to the rest of
  the body through the blood. The capillaries also
  transport nutrients, carbon dioxide, and wastes
  to and from the body.

HOW YOUR RESPIRATORY SYSTEM WORKS

• FACTS ABOUT YOUR LUNGS

11
LUNGS

• Your body needs lots of oxygen to survive. First
  air goes down the trachea, also known as your
  windpipe. Then the air goes into branch-like
  tubes in your lungs called bronchi. As the air
  goes into bronchi the air goes through smaller
  and smaller tubes. At the end of the smallest
  tubes there are little air sacs called alveoli.

12
MORE FACTS ABOUT LUNGS

• You and your systems need oxygen to keep running.
  The respiratory system is what gets the oxygen.
  When you breathe, warm air goes down down your
  trachea and into your lungs. The trachea connects
  to bronchi, which divides into smaller tubes.

The Skeletal System

• The skeletal system works when joints attach
  bones to each other and to muscles, ligaments
  hold the skeleton together, and tendons attach
  bones to muscles.

16
What Does the Skeletal System Do?

• The Skeletal System controls the body movement
  along with the muscles. The hinge joints allow
  you to bend and straighten your arms and legs.
  What allows the circular motion is the
  ball-and-socket joint. For exampleyour hips and
  your shoulders are ball-and-socket joints.

17
The Bones of Your Skeletal System Are.

• The skull, clavicle, sternum, ribs, humerus,
  spine, pelvis, femur, patella, fibula, tibia,
  phalanges (fingers and toes), radius, ulna.

18

Muscular System
19
Muscular System
Muscles help your body move. Without them you
wouldnt be able to do anything. The more weight
you put on a muscle, the bigger and stronger it
gets.
20
THE IMPORTANCE OF MUSCLES

• Muscles are one of the most important body parts.
  You couldnt hand shake without them.

22
The Nervous System

• The nervous system consists of two parts the
  central nervous system and the peripheral nervous
  system.        

23
The Central Nervous System

• The central nervous system decodes signals it
  accepts from nerves and decides what reply is
  needed. Signals sent by the brain travel through
  nerves and conduct all of the bodys muscles.

24
The Peripheral Nervous System

• The peripheral nervous system consists of
  sensory organs, like the eyes and ears,and body
  nerves. Nerves have bundles of cells called
  neurons, which are specialized cells that can
  receive signals and convey them to other neurons.

The Digestive and the Excretory Systems

• You couldnt live without them!

28
The Digestive System

• The digestive system is a system in your body
  that lets you eat.
• It also produces the nutrients in your cells need
  to produce energy.

29
The Excretory System

• The wastes of the body are taken out of the body
  in the excretory system.
