The document summarizes several key human body systems including the digestive system, respiratory system, excretory system, circulatory system, blood, and heart. The digestive system transforms food into nutrients using the digestive tract and glands. The respiratory system is responsible for breathing through inhalation and exhalation of air in the lungs. The excretory system filters waste from the blood and removes it from the body through sweat glands and the urinary system. The circulatory system transports nutrients and oxygen to cells using the heart, blood, and three types of blood vessels. Blood contains red blood cells, white blood cells and platelets suspended in plasma. The heart pumps blood around the closed, double circulatory system using rhyth

DIGESTIVE SYSTEM

4. THE RESPIRATORY SYSTEM
The respiratory system is in charge of breathing .
Makes two movements
First inhale air and it goes into the lungs
Then exhale air seding it out of the lungs

5. THE EXCRETORY SYSTEM
 Filters waste substances
from the blood.
 It removes then from the
body though excretion.
 It is made up of
Sweat glands
The urinary system

7. THE CIRCULATORY SYSTEM
 Transport nutrients and oxygen to
our cells.
 It is made up of
 The heart
 The blood
 There are three types of blood
vessels :
 The capillaries
 The veins
 The arteries

9. THE BLOOD
Is a red liquid tissue made up of cells that float in a
liquid called plasma.
It has three parts:
o Red blood cells
o White blood cells
oPlatelets

10. THE HEART
 Uses rhythmic systole and diastole
movements to pump the blood around the
body.

11. HUMAN CIRCULATION.
 Is closed and double
 Is closed,in mamals the heart septum
separates the two halves.
 Is double. The blood follows two routes
 Pulmonary circulation
 Systemic circulation
