1. BODY SYSTEMS

2. Nervous System Major Organs:
Brain, spinal cord, nerves, sense organs, receptors
Function:
Controls and coordinates body movements and senses; controls consciousness and creativity; helps monitor and maintain other body systems
Connection to other Systems:
ALL other body systems because it sends electrical signals which control their functions.

3. Skeletal Major Organs: Bones Function:
Provides structure; supports and protects internal organs
Connections to other Systems:
Muscular System, Nervous System, Circulatory System

4. Muscular Major Organs: Muscles (skeletal, cardiac, and smooth)
Function: Provides structure; supports and moves trunk and limbs
Connection to other Systems:
Skeletal System, Circulatory System, & Nervous System.

5. Digestive Major Organs:
Mouth, esophagus, stomach, liver, pancreas, small and large intestines
Function: Stores and digests food; absorbs nutrients; eliminates wastes
Connection to other Systems:
Circulatory System, Excretory System & Nervous System.

6. Digestive Path of Food: MOUTH ESOUAGHUS STOMACH SMALL INTESTINE
LARGER INTESTINE
ANUS

7. Circulatory Major Organs: Heart, blood vessels, blood Function:
Transport nutrients and wastes to and from all body tissues
Connection to other Systems:
ALL other body systems!

8. Heart to the body to the heart to lungs
Circulatory
Path of Blood:
Heart to the body to the heart to lungs

9. Respiratory Function:
Carries air into and out of lungs, (gases:oxygen and carbon dioxide)
Major Organs:
Air passages, lungs
Connection to other Systems:
ALL because it supplies the body with oxygen and takes out carbon dioxide

10. Carbon Dioxide (CO2) OUT
Respiratory
Exchange of Gases:
Oxygen (O2)IN
Carbon Dioxide (CO2) OUT

11. Urinary Major Organs: Kidneys, ureters, bladder, urethra, Function:
Eliminates waste; maintains water and chemical balance
Connection to other Systems: Circulatory system- clean blood, excretory system-eliminates waste

12. Excretory Systems Major Organs: kidneys, large intestines, lungs, skin
Function:
To get rid of wastes that could harm the body
Connection to other Systems:
Respiratory system exhales waste gas, Integumentary system sweats of waste, Urinary system- liquid wastes are released in urine, Digestive system- large intestines release solid waste

13. Integumentary System Main Organs Skin, hair, nails Function:
The body's first line of defense. Keeps pathogens from entering the body.
Connection to other Body System:
Connected to immune system because to also help protect us

14. Immune Major Organs: Lymph nodes and vessels, white blood cells
Function: Provides protection against infection and disease
Connection to other Systems:
Circulatory System, Digestive System, Urinary/Excretory System & Nervous System.

15. Lymphatic System Main Organs: tonsils, thymus, spleen, lymph nodes
Functions:
Transports lymph through the body. Lymph is a clear fluid that aids during infections
Connections to Other Body Systems
Immune system-protection Circulatory system- transport.

16. Endocrine Major Organs:
Glands (such as adrenal, thyroid, and pancreas), hypothalamus
Function:
Maintains homeostasis; regulates metabolism, water and mineral balance, growth and sexual development, and reproduction
Connection to other Systems:
ALL other body systems because it supplies the hormones that help them function.

17. Reproductive Major Organs:
Ovaries, uterus, mammary glands (females), testes (males)
Function:
Produces offspring
Connection to other Systems:
Nervous System, Circulatory System, & Endocrine System,
