what is the female end of a garden hose
Garden hose Each male end of a typical garden hose can mate with the female connector on another, which allows multiple garden hoses to be linked end-to-end to increase their overall length. Small rubber or plastic washers (often confusingly called "hose washers") are used in female ends to prevent leakage, because the threads are not tapered and are not used to create a seal. Sometimes the gaskets stiffen, disintegrate, or fall out of older hoses, which results in pressurized leakage spraying from the hose; simply replacing the washer insert often fixes the problem.
Endometrium The endometrium is the inner epithelial layer, along with its mucous membrane, of the mammalian uterus. It has a basal layer and a functional layer; the functional layer thickens and then is sloughed during the menstrual cycle or estrous cycle. During pregnancy, the glands and blood vessels in the endometrium further increase in size and number. Vascular spaces fuse and become interconnected, forming the placenta, which supplies oxygen and nutrition to the embryo and fetus.[1][2] The presence of commensal bacteria in the uterus and endometrium has been identified.[3]
