BODY SYSTEMS
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.
Skeletal
• Major Organs:
Bones
• Function:
Provides structure; supports and protects
internal organs
• Connections to other Systems:
Muscular System, Nervous System, Circulatory
System
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.
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.
Digestive
• Path of Food:

LARGER INTESTINE
ANUS
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!
Circulatory
• Path of Blood:
• Heart to the body to the
heart to lungs
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
Respiratory
• Exchange of Gases:
• Oxygen (O2)IN
• Carbon Dioxide (CO2) OUT
Urinary
• Major Organs:
Kidneys, ureters, bladder, urethra,
• Function:
Eliminates waste; maintains water and
chemical balance
• Connection to other Systems: Circulatory
system- clean blood, excretory systemeliminates waste
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
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
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.
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.
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.
Reproductive
• Major Organs:
Ovaries, uterus, mammary glands (females),
testes (males)
• Function:
Produces offspring
• Connection to other Systems:
Nervous System, Circulatory System, &
Endocrine System,
