LARGE CELLS THAT FORM THE BLOOD-TESTIS BARRIER ARE Select one: Leydig cells Sertoli cells spermatocytes spermatogonia spermatids

The correct answer is Sertoli cells.<br /><br />Sertoli cells are large cells that form the blood-testis barrier in the seminiferous tubules of the testes. The blood-testis barrier is a physical barrier that separates the developing sperm cells in the seminiferous tubules from the blood vessels and immune protect the developing sperm cells from potential damage or immune rejection.<br /><br />Sertoli cells play a crucial role in the development and maturation of sperm cells. They provide nourishment, support, and hormonal regulation to the developing sperm cells. Additionally, Sertoli cells produce fluid that helps to transport the sperm cells through the seminiferous tubules and into the epididymis for storage and maturation.<br /><br />Leydig cells, on the other hand, are located in the interstitial tissue of the testes and are responsible for producing testosterone, a male sex hormone. Spermatocytes, spermatogonia, and spermatids are all stages of sperm cell development, but they do not form the blood-testis barrier.
