For these reasons, most glassware is made from a borosilicate glass, such as Pyrex or Kimax. Some glassware isn't glass at all, but inert plastic such as Teflon. Each piece of glassware has a name and purpose. Use this photo gallery to learn the names and uses of different types of chemistry laboratory glassware.
The epididymis is a firm tube that lies on the back surface of each testicle. It is coiled in order to fit a length of nearly 20 feet into a small space. This long length acts as a storage space for the sperm and gives sperm time to mature.
B. Concentration of Spermatozoa. The epididymis removes water and particulate material from sperm cells and from the fluid transporting them from the testes. Fluid production by the testes is great and 90% of that fluid is absorbed in the epididymis.If the vas efferentia or epididymis are ligated, water accumulation causes the testes to swell in size..
