Bio Practical Flashcards
Umbilical cord
Ventral exterior, during gestation the umbilical cord brings oxygen and nutrition from the mother’s bloodstream into the fetus, as well as removing nitrogen wastes and carbon dioxide
Navel
scar from umbilical cord’s removal
scrotal sacs
posterior end of the body between the upper hind legs, contains the testes, keeps testes at a good temperature lower than the body cavity but higher than air temp
Urogenital opening(Male)
located directly posterior to the navel, serves as opening for the otherwise sheathed penis as well as the exit for urine
Urogenital opening(Female)
located immediately below the anus, just beneath the tail, receives penis for mating and is exit for urine
genital papilla
a small fleshy structure that protects the female urogenital opening as well as separating it from the anus
Dorsal
toward the backbone
Ventral
below, belly-up view
Anterior
in front of, toward the head end
Posterior
behind, toward the tail
Medial
toward the center line
Lateral
Side view, toward the side
Liver
Digestive system, against posterior side of the diaphragm, jobs include making bile and filtering absorbed nutrients carried by the hepatical portal vein from the small intestine
gall bladder
Digestive system, posterior side of the liver, stores bile
Stomach
Digestive system, animal’s left, beneath liver, protein digestion begins in the stomach and all foods are liquefied for further digestion in the small intestine
Spleen
Circulatory system, attached to the left posterior sides of the stomach, stores and recycles red blood cells
Esophagus
Digestive system, travels from mouth dorsal to the trachea to the stomach, transports food eaten to the stomach
Small intestine
Digestive system, large mass of small tubes in the abdominal cavity, where most digestion and absorption of nutrients happens
Pyloric Sphincter
Digestive system, ring of muscles that regulates the speed that liquefied food passes from the stomach into the duodenum
Common Bile Duct
Digestive system, enters duodenum from the liver, bile from the liver accumulates in the gall bladder then enters the duodenum from this duct
Pancreas
Digestive system, produces digestive enzymes which enter the duodenum when food is present, also produces insulin which regulates the use of glucose by cells
Cecum
Blind tip of cecum corresponds to our appendix, in herbivores it houses a population of cellulose-digesting bacteria and protozoa
Large intestine
Digestive system, mass of large tubes on pig’s left posterior to the stomach, indigestible food material is decomposed here for later elimination
