Upper portions of the kidneys are somewhat protected by the eleventh and twelfth ribs Figure Each kidney weighs about — g in males and — g in females.
Nephron , functional unit of the kidney , the structure that actually produces urine in the process of removing waste and excess substances from the blood. There are about 1,, nephrons in each human kidney. The most primitive nephrons are found in the kidneys pronephros of primitive fish, amphibian larvae, and embryos of more advanced vertebrates.
The kidneys are two bean-shaped organs in the renal system. They help the body pass waste as urine. They also help filter blood before sending it back to the heart. Nephrons are the most important part of each kidney. They take in blood, metabolize nutrients, and help pass out waste products from filtered blood. Each kidney has about 1 million nephrons.
Two bean shaped kidneys are attached to the posterior abdominal wall, one on each side of the vertebral column. The kidneys have a tough fibrous capsule irregular dense connective tissue for protection. Otherwise they have very little connective tissue between the nephrons. The kidney has a granular cortex outer region.
