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.
There have never been sufficient kidney donations to provide a kidney to each person needing one. In this video, Dr. The paired kidneys lie on either side of the spine in the retroperitoneal space between the parietal peritoneum and the posterior abdominal wall, well protected by muscle, fat, and ribs. The left kidney is located at about the T12 to L3 vertebrae, whereas the right is lower due to slight displacement by the liver. 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.
About Translations. This section of notes gives an overview mainly of adult renal histology, see also Renal System Development notes. Moodle - Virtual Slides requires Moodle log in. Mouse renal podocyte EM . On the outside of the capillary, the foot processes FP cover a major part of the glomerular basement membrane GBM circumference. The endothelial cell coats the inner surface of the capillary wall and is followed by the three layers of the glomerular basement membrane GBM.
The Kidney pp Cite as. This chapter focuses on three levels of kidney morphology: embryologic development, gross anatomical structures, and histological features. The first section illustrates the progression of kidney development from initial rudimentary pronephroi to metanephroi or permanent kidneys residing in the posterior abdominal wall. In the second section, gross features of the kidney are discussed, along with its relationship to other structures, vascular perfusion, lymphatic drainage, and nervous system innervation. The final section explores the microanatomical structures that allow the kidney to function as an integral component of the urinary system.
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. It has this appearance because it is full of ovoid filtration units.
Although the histological traits of kidney structures are well known in fish the wide variations in their anatomy, histology, and cytology, related to.
The kidneys are located at the rear wall of the abdominal cavity and they are protected by the ribcage. The kidneys are the primary functional organ of the renal system. They are essential in homeostatic functions such as the regulation of electrolytes, maintenance of acid—base balance, and the regulation of blood pressure by maintaining salt and water balance.
