Fetal Pig and Earthworm Anatomy Practice Flashcards

This set covers the vocabulary and anatomical structures of the fetal pig's urogenital, circulatory, and respiratory systems, as well as internal structures of the earthworm.

Renal vein

A blood vessel that carries deoxygenated blood away from the kidney.

Renal artery

A blood vessel that carries oxygenated blood to the kidney.

Urinary bladder

The organ that stores urine before it is excreted from the body.

Ureter

The tube that transports urine from the kidney to the urinary bladder.

Urethra

The duct that carries urine from the bladder to the outside of the body.

Epididymis

A coiled tube resting on the testis where sperm are stored and matured.

Vas deferens

The tube (also referred to as the ductus deferens) that carries sperm from the epididymis.

Gubernaculum

A structure that connects the testis to the scrotal sac and assists in the descent of the testes.

Bulbourethral gland

A gland in the male reproductive system located near the base of the penis.

Ovary

The female reproductive organ responsible for producing eggs.

Uterine horn

The branches of the uterus in the fetal pig where embryonic development occurs.

Urogenital sinus

The chamber where the vagina and the urethra join in the female fetal pig.

Crop

The thin-walled storage area for food in the earthworm's digestive system.

Gizzard

The thick-walled, muscular structure in the earthworm used for grinding food.

Aortic arches

The five muscular vessels in an earthworm that function as hearts to pump blood.

Cerebral ganglia

The primitive brain of the earthworm located at the anterior end.

Protonephridia

Excretory organs found in the internal anatomy of the earthworm.

Larynx

The structure at the top of the trachea commonly known as the voice box.

Diaphragm

The muscular partition that separates the thoracic cavity from the abdominal cavity.

Spleen

A flattened organ located near the stomach involved in blood filtration and immune function.

Anterior vena cava

A large vein (also called the cranial vena cava) that returns blood from the head and upper body to the heart.

Common carotid artery

Arteries located in the neck that supply blood to the head.
