Long coiled tube stretching through the epididymi connecting to the ductus deferens

Question 18

Ductus deferens

Answer 18

• connected to epididymi

• means widening

* enlarged end of ductus deferens

Question 20

Ejaculatory ducts

Answer 20

• located in the prostate gland
• are two of them
• short tubes that connect each vas deferens with urethra
• allow sperm movement in the urethra
• collected secretions from prostate and seminal vesicles

Question 21

Urethra

Answer 21

• smooth muscle
• originates in the urinary bladder, passes through the prostate then through the penis
• long tube containing smooth muscle in the wall
• urine and sperm pathway

Question 22

Secretory glands

Answer 22

• are exocrine
• secrete fluids in tubes that transport the materials to a different site
• glands include: 2 seminal vesicles, 2 bulbourethral and prostate

Question 23

Prostate gland

Answer 23

Largest gland
•urinary bladder
•ejaculatory ducts and urethra pass through this

Question 24

2 seminal vesicles

Answer 24

2 glands located near the ampulla of the ductus deferens

•empty secretions to aid in sperm movement

Question 25

2 Bulbourethral glands

Answer 25

2 smaller glands •aka Cowper's glands Aid in sperm movement
