Flashcards in Lab 11 pt.3: Urogenital System Deck (19):
1

Organs located on the posterior dorsal wall of the abdominal cavity. Lies beneath a layer of connective tissue on either side of the dorsal aorta. Produces urine.

Kidney

2

These are the paired tubes which join the kidneys and the urinary bladder. They conduct urine to the bladder.

Ureter

3

This is the large sack which is located between the two umbilical arteries. It is the temporary storage chamber for urine.

Urinary Bladder

4

This tube transports urine to the outside when the urinary bladder is emptied. It is relatively short in females, and just ventral to the anus. It is much loner in males, and ends at the urogenital opening. It also functions to conduct semen in males.

Urethra

5

This structure is the external pouch or sac located just ventrally to the tail and anus. It contains the testes.

Scrotum

6

These are the small, bean shaped male reproductive organs contained within the scrotum. They produce sperm and testosterone.

Testes

7

These are located superficially on the posterior margin of the testes. They are long and coiled tubule which coils to use very little space. They function in sperm storage and maturation.

Epididymis

8

These are the ducts which connect the epididymis to the urethra. They turn over the ureters to join the urethra just anterior to where the ureters enter the bladder. Their function is to transfer sperm from the epididymis to the urethra during an ejaculation.

Ductus deferens or Vas deferens

9

These are the passageways through the abdominal wall in the groin of males through which the ductus deferens and blood vessels pass to the testes.

Inguinal canal

10

These are small glands are located near the juction of the ductus deferens and the urethra. They produce some of the seminal fluid.

Seminal vesicles

11

A pair of glands near the base of the penis in the pelvic canal on either side of the urethra. They produce some of the seminal fluid. It is also called "Cowper's Glands".

Bulbourethral glands

12

The male coplulatory organ located ventrally on the exterior abdominal wall, just posterior to the umbilical cord.

Penis

13

This is a small gland which surrounds the junction of the ductus deferens and the urethra. It produces some of the seminal fluid. To find it, dissect between the seminal vessels.

Prostate gland

14

These are the female reproductive organs. They are located on the dorsal abdominal wall, just posterior to the kidneys. They produce eggs and hormones, like estrogen and progesterone.

Ovaries

15

These are the small ducts found between the ovaries and uterine horns. They are the passgeways through which eggs reach the uterus. Fertilization occurs in the uterine tubes.

Uterine tubes or Fallopian tubes

16

These are the wider tubes located at the end of the uterine tubes and connected to the uterine body. Embryos develop within these tubes.

Uterine horns

17

This is the single, wider tube formed by the union of the two uterine horns. The cervix is at its posterior end.

uterine body

18

This is the most posterior tube of the female reproductive tract. It is the female copulatory organ and receives the male's penis during copulation.

Vagina

19

This is the female's external genitalia located directly below the anus.

Genital papilla
