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:• MOUTH

• ESOPHAGUS

• STOMACH

• SMALL INTESTINE

• 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 system-eliminates 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

• 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

Integumentary System

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.

• 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.

Lymphatic System

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,
