Final answer:
The two mechanisms that move sperm from the seminiferous tubules to the epididymis are the contraction of smooth muscles lining the epididymal tubes and the peristaltic contractions of the efferent ducts.
Step-by-step explanation:
The two mechanisms that move sperm from the seminiferous tubules to the epididymis are:
- The contraction of smooth muscles lining the epididymal tubes, which predominantly moves the sperm along the length of the epididymis.
- The peristaltic contractions of the efferent ducts that transport the immature sperm from the seminiferous tubules to the epididymis.
These mechanisms contribute to the maturation and storage of sperm in the epididymis until ejaculation occurs.
