1. Order of organs from inside out
Fat bodies (these should be glued completely to frog)
Bladder and kidneys (glue the tip of the bladder to the line nearest the bottom of the opening of the frog)
Stomach and Intestines (glue the end of the stomach to the top of the small intestine to show they are connected.)
Lungs and Heart (glue the top part of the lung to the line at the top of the opening on the frog.)
Liver (glue the top two lobes of the liver to the line at the top of the opening. You should be able to see the heart just under the liver)
Blood Vessel and Spleen (glue the blood vessel to the top, overlapping where you glued the lungs, the spleen should be at the bottom of the blood vessel.)
You will be overlapping these so that you can flip them upward. 6 5 4 5 3 3 1 1 2

2. Key Internal Organs of the Frog
Body System
Major Function
brain
nervous 
thinking and coordination of body activities
heart
circulatory
pumps blood through the body
stomach
digestive
stores and begins the chemical digestion of food
small intestine
finishes chemical digestion and absorbs digested nutrients into the blood
liver
makes bile, detoxifies poisons, many other functions
gall bladder
stores bile from liver for release into small intestine to aid in fat digestion
lungs
respiratory
exchanges gases with the external environment (aided by the skin in the frog)
kidneys
excretory
filter wastes from the blood
ureter
carries wastes to the urinary bladder
urinary bladder
stores urine before its release from the body
pancreas
endocrine/digestive
produces hormones like insulin which regulate blood sugar, produces pancreatic juice which aids in digestion in the small intestine
ovaries
reproductive
makes eggs in female frog
testes
makes eggs in male frog
FROG FOLDABLE DIRECTIONS
You will create a frog foldable with its parts and color the parts, then cut them out with the label attached and glue them in the order shown. Some parts will be glued over others, but you will need to be able to flip them up so do not glue them completely down.
Color the fat bodies yellow. Cut them out and glue them as shown.
Color the entire frog body green. Color the inside and flaps a lighter green.
Color the kidneys marroon and the bladder green. Cut them out with the labels attached and glue them to the frog.
Color the stomach and esophagus orange, and the pancreas light blue. Cut them out with the labels attached and glue them to the frog.
Color the small intestine dark blue and the large intestine purple. Cut them out with the labels attached and glue them to the end of the stomach and then to the frog.
Color the heart red and the lungs pink or light red. Cut them out with the labels attached and glue them to the frog.
Color the liver brown and the gall bladder gray. Cut them out with the labels attached and glue them to the frog.
Color the blood vessel red and the spleen purple. Cut them out with the labels attached and glue them to the middle of the frog.
