Organ systems in Human body

 

The human body has 12 organ systems

The 12 human body systems are the

1) cardiovascular system,

 2)the digestive system

,3) the endocrine system, 

4)the immune system

, 5)the integumentary system, 

6)the lymphatic system, 

7)the muscular system,

 8)the nervous system,

 9)the reproductive system, 

10)the respiratory system,

 11)the skeletal system, and 

12)the urinary system.

All of these systems work together to ensure that our bodies work correctly:

• The cardiovascular (or circulatory) system
•  transports blood, oxygen, and nutrients throughout the body.
• The digestive system 
• takes in and processes food.
• The endocrine system 
• produces hormones that regulate metabolism, growth and development, tissue function, sexual reproduction, sleep, and mood.
• The immune systhttps://janatkiran.blogspot.com/?m=1
• immune system
•  fights infection.
• The integumentary system 
• protects the body from outside damage.
• The lymphatic system 
• connects the lymph nodes in our bodies and helps the circulatory and immune systems.
• The muscular system 
• allows us to move.
• The nervous system
•  transmits signals through the body and controls voluntary and involuntary actions.
• The reproductive system 
• allows us to have sex and children.
• The respiratory system
•  enables us to take in oxygen and expel carbon dioxide as we breathe.
• The skeletal system
•  gives our bodies a framework and supports the systems.
• The urinary system 
• expels waste.

All of these are only some of the main functions of each system, but each system performs many others.
