Summary Introduction
To review:
The sequence of ducts through which the sperm passes from the production in seminiferous tubules to the ejaculation out the external urethral orifice.
Introduction:
There are numerous tissues that are associated with the secretion/production of different products in the body. The male reproductive system is designated with the task of production, maturation and transportation of the human gametes or sperm. The male reproductive system has specialized organ/structures to accomplish the task of production of sperm.

Where sperms are produced. 2.) Where sperms are temporarily stored. 3.) Supports the testis and epididymis 4.) Where the sperm passes through from the testis before it joins the urethra. 5.)

Secretes fluid that also provides alkalinity to the semen; Contains proteilytic enzymes, citric acid, phosphates, and lipids. 8.) Paired goands that produce clear, viscous secretion (pre-ejaculate) that helps to lunricate the urethra for sperm to pass through, neutralizing traces of acidic urine in the urethra, and helps flush out any residual urine or foreign matter.arrow_forward
