d) 6, 8, 2, 4, 1, 3, 5, 9, 7

Answer 1

The correct order of ducts for sperm travel from production to exit is seminiferous tubules, straight tubules, rete testis, efferent ducts, ductus epididymis, ductus deferens, ejaculatory duct, prostatic urethra, membranous urethra, and spongy urethra.

Step-by-step explanation:

The correct order of ducts from the site of sperm production to the point of exit from the body is as follows:

1. Seminiferous tubules
2. Straight tubules (tubuli recti)
3. Rete testis
4. Efferent ducts
5. Ductus epididymis
6. Ductus (vas) deferens
7. Ejaculatory duct
8. Prostatic urethra
9. Membranous (intermediate) urethra
10. Spongy (penile) urethra

This progression traces the path of sperm from their origin in the seminiferous tubules of the testes, where they are produced, through a series of ducts, to the epididymis for maturation. They are then transported via the ductus deferens, mixed with seminal fluid from seminal vesicles, and pass through the ejaculatory duct into various sections of the urethra before exiting the body.
