So let's review what we have learned so far!

• What is the skeleton responsible for in the human body?

• What are muscles responsible for in the human body?

• How are these two organs alike?

Organs and their Functions

Organs for Waste Removal: Skin


These organs are responsible for helping run our entire body and everything in it!

Today we are going to talk about the command center organs.


Command Center Organs: Heart

Your heart is located in your chest beneath your rib cage and is about the size of your fist.

It pumps blood through your blood vessels to all parts of your body.

Without it, nothing in your body would be able to function.

Organs for Digestion:

These organs are responsible for digesting food in your body.

Digestion is the process your body goes through to break down foodinto nutrients that your body needs.


Organs for Digestion: Stomach

When you eat food, it goes from your mouth, through the esophagus, and into your stomach.

The muscles in your stomach crushes the food and then release stomach acid to further break down food.


Organs for Digestion: Stomach


Organs for Digestion: Liver

Cleans the blood coming from the digestive organs and changes food into forms that can stored.

Your liver makes a digestive juice called bile. Bile neutralizes stomach acid.


Organs for Digestion: Pancreas

Your pancreas releases chemicals that break down food into the small intestines.

It produces insulin that is used to break down sugar.


Organs for Digestion: Liver and Pancreas


Organs for Digestion: Small Intestine

The small intestine uses the digestive juices from the liver and pancreas and finishes digesting the food.

Nutrients from this digested food move into your blood.

Materials that your body does not need are moved into your large intestine.


Organs for Digestion: Small Intestine


Organs for Digestion: Large Intestine

Your large intestine removes water from the material sent by your small intestine.

The water moves into your blood.

The solid wastes move into your rectum, and out of your body.


Organs for Digestion: Large Intestine


Now let’s move onto the next system of organs: Organs for Waste Removal

These organs are responsible for removing excess water, waste material, and harmful substances from the body.


Organs for Waste Removal: Kidneys

The kidneys filter harmful things out of your blood. Wastes carried in your blood collect in the kidneys and form urine.

The urine is then sent to the bladder.


Organs for Waste Removal: Bladder

The waste, or urine, your kidneys send out is sent to your bladder.

Your bladder collects and stores urine until you are ready to release it.


Organs for Waste Removal: Kidneys and Bladder

Organs and their FunctionsOrgans for Waste Removal: Lungs

Your blood travels through blood vessels, to your lungs.

The carbon dioxide and water leave the blood and enter your lungs.

The liquid water changes to water vapor.

Every time you breathe out, carbon dioxide gas and water vapor leave your body.
