1. 1. Eye – to see 2. Tympanic Membrane (Tympanum) – to hear 3. Hind Leg - jump 4. External Nare - breath 5. Mouth - eat 6. Front Leg – movement 7. Nares - breath 8. Maxillary teeth – hold prey 9. Vomerine teeth – chew prey 10. Tongue – capture prey Vomerine – chew the prey. Maxillary teeth hold the prey Capture prey with their tongue. USE THEIR EYES to push food in their gullet. EXTERNAL STRUCTURES OF THE FROG - DAY 1 11. Eustachian tube – equalize pressure

2. REVIEW: How does the frog eat? Look inside his mouth. What are the two pads on the roof of his mouth? He uses his EYES to push the food down into his gullet. (his tongue is connected in the front of his mouth – so he can’t use it to push down food like we do)

4. Internal Anatomy – DAY 2 4. LIVER Draw in the gall bladder 9.HEART 3. LUNGS Use the CIRCULATORY SYSTEM graphic flow chart to illustrate the flow of blood through the frog

5. CIRCULATORY SYSTEM LUNGS OUT TO BODY FROM BODY From body  Right Atrium  Ventricle  LUNGS  Left Atrium  Ventricle  out to body

6. DETERMINE GENDER – DAY 2 IF YOU FIND BLACK AND WHITE SMALL BALLS INSIDE THE FROG – THESE ARE EGGS. – Congratulations you have a GIRL!!!!  IF YOU HAVE 2 SMALL KIDNEY BEAN SHAPED ORGANS LOCATED NEAR THE SPINE – congratulations you have a BOY!!!

7. LIFE CYCLE USE WHAT YOU KNOW TO FILL IN THE LIFE CYCLE DIAGRAM ON THE BACK OF YOUR DISSECTION PACKET.

8. INTERNAL ANATOMY – DAY 3 DIGESTIVE SYSTEM 1 – GULLET 2 – ESOPHAGUS Find the pancreas – located near the back of the stomach, it looks like a think ribbon 10 – STOMACH Open up the stomach by cutting at the top and bottom of it. Put your scissors inside the cut and it open to reveal what is inside

9. INTERNAL ANATOMY – DAY 3 DIGESTIVE SYSTEM 12 – SMALL INTESTINE Find the connection where the small intestine and the large intestine connect 13 – LARGE INTESTINE – do not cut this…it contains poop 11 – MESENTERY – connective tissue that keeps all internal organs together 14 – SPLEEN – draw in the spleen in the mesentery by the small intestine – removes old blood cells

10. FILL IN THE DIAGRAM Use the information you have gathered to fill in the diagrams for the digestive system on your note packet.

11. EXCRETORY SYSTEM FIND THE KIDNEYS (maroon/red structures near the frog’s spine) 5 – KIDNEY 7 – URETER 8 – BLADDER 6 – CLOACA USE WHAT YOU KNOW TO FILL IN THE EXCRETORY SYSTEM DIAGRAM ON THE BACK OF YOUR PACKET
