Final answer:
The two main structures that make up the spermatic cord are the vas deferens and the testicular blood vessels, which supply the testes with oxygen and nutrients.
Step-by-step explanation:
The Components of the Spermatic Cord
The spermatic cord is an essential structure within the male reproductive system that contains several vital components required for sperm production and transport.
There are multiple elements that make up the spermatic cord, but primarily, there are two main structures: the vas deferens (also known as the ductus deferens) and the testicular blood vessels, which include arteries (branches of the abdominal aorta) and veins that supply the testes.
The vas deferens is the duct that transports mature sperm from the epididymis to the ejaculatory ducts for ejaculation.
On the other hand, the testicular blood vessels are part of the spermatic cord and provide essential nutrients and oxygen supply to the testes while also aiding the removal of waste products.
Other components of the spermatic cord include lymphatics, nerves, and the cremaster muscle fibers, which together support the physiological functions of the testes and sperm maturation processes.
Although the question specifically asks for two structures, knowing the additional components is vital for a comprehensive understanding of the spermatic cord's function in the male reproductive system.
