a sac of loose skin that holds two male glands called the testes (or testicles).

○ scrotum

○ penis

○ epididymis

○ perineum

Explanation:

For the first question, the penis is the male external organ with both excretory (urine passage) and sexual (sperm passage via urethra) functions. The urethral opening is just the opening of the urethra, not an organ. The testes are internal reproductive glands. The scrotum is a sac (as per the second question) holding the testes.
For the second question, the scrotum is specifically described as a sac of loose skin holding the testes. The penis is a different organ (as above). The epididymis is a coiled tube on the back of each testicle for sperm storage. The perineum is the area between the anus and scrotum (in males) or vulva (in females), not a sac holding testes.

Answer:

First question: penis
Second question: scrotum
