The plasma membrane is composed of:
- Lipid bilayer (highlights: phosphoglycerides such as phosphatidylethanolamine or cephalin, phosphatidylcholine or lecithin, phosphatidylinositol and phosphatidylserine; sphingolipids formed by ceramide and fatty acids, and cholesterol)
- Proteins: integral, peripheral and membrane fixed to lipids.
- Glucids: covalently bound to proteins or lipids; they can be poly or oligosaccharides. They form the glycocalix on the outside of the membrane and its function is to support the membrane and cell recognition.
The kidneys form the urine and account for the other functions attributed to the urinary system. The ureters carry the urine away from kidneys to the urinary bladder, which is a temporary reservoir for the urine. The urethra is a tubular structure that carries the urine from the urinary bladder to the outside.
