BIOL 1120: General Biology II
Outline for Lab Test 2 on Animals
Classification
Kingdom Animalia (multicellular, cells have nucleus (eukaryotic), heterotrophic
consumers)
Phylum Echinodermata – includes spiny-skinned animals such as the
starfish and sand dollar
Phylum Chordata – includes primarily vertebrates such as fish,
amphibians, reptiles, birds, and mammals (such as dogs, cats, and
humans)
Subphylum Vertebrata
Class Amphibia – includes cold-blooded animals with thin, moist
skin and a 3-chambered heart such as frogs
Class Mammalia - includes warm-blooded animals with body hair
mammary glands, and a 4-chambered heart such as pigs
Phylum Echinodermata
Starfish anatomy
- structures: mouth, anus, stomach, digestive glands, gonads, endoskeleton,
tube feet, ampullae, canals (stone, ring, and radial), madreporite (sieve plate),
central disk, arms
Additional Echinoderm Specimens
-various starfish, sand dollar, sea urchin, sea cucumber, brittle star
Phylum Chordata
Frog anatomy (know how to tell the sexes apart)
- nictitating membrane (over eye), tympanic membrane/tympanum, vomerine
teeth, liver, gall bladder, lungs, heart (3 chambers--right atrium, left atrium,
ventricle), stomach, small intestine, large intestine, spleen, urinary bladder,
ovaries/testes, kidneys, fat bodies
Fetal Pig anatomy (know how to tell the sexes apart)
- anus, urogenital opening, urogenital papilla (in female), scrotum (in male),
larynx, thymus gland, thyroid gland, heart (4 chambers--right atrium, left atrium,
right ventricle, left ventricle), lungs, diaphragm, liver, gall bladder, stomach,
spleen, pancreas, small intestine, large intestine, urinary bladder, umbilical
cord, umbilical arteries, umbilical vein, kidneys, ovaries/testes
