If you have two healthy kidneys, you have 100 percent of your renal function. This is more renal function than you really need. Some people are born with only one kidney, and these people are able to lead normal, healthy lives. Many people donate a kidney for transplantation to a family member or friend.
Mullerian Duct. Definition - What does Mullerian Duct mean? The Mullerian ducts are paired ducts which coexist in a developing fetus, from which the female internal reproductive organs are derived by a lateral fusion of the two ducts. These ducts conjoin and form the uterus, the cervix, the fallopian tubes and upper end of the vagina.
The nasolacrimal duct (sometimes called the tear duct) carries tears from the lacrimal sac into the nasal cavity.The opening of the nasolacrimal duct into the inferior nasal meatus is partially covered by a mucosal fold (valve of Hasner or plica lacrimalis).Excess tears flow through nasolacrimal duct which drains into the inferior nasal meatus.his is the reason the nose starts to run when a person is crying or has watery eyes from an allergy, and why one can sometimes taste eye drops. Like the lacrimal sac, the duct is lined by stratified columnar epithelium containing mucus-secreting goblet cells, and is surrounded by connective tissue.
