The document provides notes on the anatomy of frogs, describing the key internal and external structures. It outlines the head region including ears, vomerine teeth, and maxillary teeth. It then details the chest region containing the heart, lungs, and liver. The upper and lower abdomen are described next, listing the stomach, intestines, and cloaca. The document concludes with notes on fat bodies, male and female reproductive parts, and diagrams to draw labeling external and internal frog anatomy.

Frog Notes

2. (1) The Head
• Ears:
– Thin membrane circles near eyes.
– Allow for hearing.
• Vomerine Teeth:
– Small, swollen bumps.
– Roof of inside mouth, by nose.
– Help hold prey.
• Maxillary Teeth:

– Bring in oxygen gas, and release carbon dioxide
gas.

• Liver:
– Gray-ish colored lobes (looks like lungs)
– Break down misfunctioning blood cells, metabolize
toxins and fats.

5. (4) The Lower Abdomen
• Intestines:
– Flesh-colored tube
– Absorb food nutrients + excrete waste
– Connected to stomach.
• Cloaca:
– Multipurpose Hole  Sperm/Eggs, Urine and Fecal
Matter all come out of here.
– End of Intestine + Exiting Waste Hole.

6. (5) Fat Bodies
• Yellow-ish squiggly noodles
• Additional energy storage + body heat.
• Sides of body (internal), along abdomen.
