The document summarizes the main human body systems. It describes the muscular system which consists of about 650 muscles that help with movement and pumping blood. The circulatory system moves blood, nutrients, and gases around the body using the heart, blood vessels, and blood cells. The digestive system breaks down food using organs like the mouth, esophagus, stomach, and intestines and the urinary system eliminates waste from the kidneys, ureters, bladder and urethra. The skeletal system provides structure and movement with 206 bones and the respiratory system takes in oxygen and expels carbon dioxide using the trachea, diaphragm and lungs. The nervous system controls both voluntary and involuntary actions through the brain, spinal

 The body's muscular system consists of about 650
muscles
 Those functions are three: 1º ) help with voluntary
movement and movement of the bones 2º) help to
move substances through organs and 3º)help to
pump blood around the body (heart).
 The movements could be voluntary and involuntary

 The job of the circulatory system is to move blood,
nutrients, oxygen, carbon dioxide and others around
the body. It consists of the heart, blood, arteries and
veins( capillaries too).
 Exists the blood cells that travel in the blood.
Circulatory System

6.  The digestive system consists of a series of connected organs that together with
the urinary system allow the body to break down, then absorb food and remove
waste in the end. It includes the mouth, esophagus, stomach, small intestine,
large intestine, rectum, and anus. Also play a role in the digestive system the
digestive juices.

8. 
 The urinary system helps to eliminate waste from the body, which is produced
when certain foods are broken down and there are things that the body don’t
use. The whole system includes two kidneys, two ureters, the bladder and the
urethra. Urine produced by the kidneys travels down the ureters to the bladder,
and exits the body through the urethra.

10. 
 Our bodies are supported (hold) by the skeletal
system, which consists of 206 bones that are
connected by tendons to the muscles.
 The skeleton not only helps us move, but it's also
helps to produce blood cells and the storage of
calcium. The teeth are also part of the skeletal system,
but they aren't considered bones.
Eskeletal System

12. 
 The respiratory system allows us to take in (breathe
in) vital oxygen and expel (breathe out) carbon
dioxide in a process we call breathing. This system
have the trachea, the diaphragm and the lungs.
Respiratory System

14. 
 The nervous system controls both voluntary action
(like conscious movement, use a pen) and
involuntary actions (like breathing), and sends
signals to different parts of the body.
 The central nervous system includes the brain and
spinal cord, then the signals pass to the nerves that
connect all parts of the body to the central nervous
system.
