1. My Organs and Systems Booklet

2. Reproductive
Purpose: To create a new organism to add to the specie’s population
The purpose of the testes is to make male hormones and sperm
And the Vas deferens, and Epididymus are the ducts that bring the sperm to the penis
The female organ that creates the eggs and female hormones is the ovary,
and the uterus attaches to the eggs to help them grow into fetuses (babies)

3. Circulatory
To transport materials throughout the body with the help of blood (materials can be oxygen, waste, or nutrients)
The heart’s job is to pump blood throughout the body
Veins go from the body to the heart (CO2)
Arteries go from the heart to the body (O2)

4. Excretory To pee out, or remove liquid waste from the body
The Kidneys are the organs that filter waste and toxins out of the blood
The ureters are the organs that connect the kidney to the bladder
And the bladder holds urine until it is ready to be released

5. Nervous
To send messages to the body- to control movement, thinking and sensing
The brains purpose is to send messages & signals to the body for sensing, thinking, and moving
The spinal cord sends messages from brain to body and back from body to brain

6. Digestive
To eat food and absorb nutrients while removing unneeded waste.
The small intestine is the main absorbing organ for nutrients from food to the body
The stomach breaks down food into chyme, and the liver filters blood from the digestive system.

7. Respiratory To bring oxygen into the body and remove carbon dioxide
The Lungs help us to exchange carbon dioxide with Oxygen so we can breathe.

8. Skeletal To provide support and protection to the body
The job of all bones are to either support our weight, or protect our organs depending on their location. Ex- the skull protects the brain

9. Muscular System To allow the body to move
The job of all muscles is to move specific parts or the body- The Gluteus Maximus (buttocks muscle) allows us to run and walk
