The 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. They are roughly the size of your fist, and the male kidney is typically a bit larger than the female kidney. The kidneys are well vascularized, receiving about 25 percent of the cardiac output at rest. There have never been sufficient kidney donations to provide a kidney to each person needing one.

Gross Anatomy of the Kidney
Their main function is to filter and excrete waste products from the blood. They are also responsible for water and electrolyte balance in the body. Urine is transported from the kidneys to the bladder by the ureters. In this article we shall look at the anatomy of the kidneys — their anatomical position, internal structure and vasculature. Each kidney is approximately three vertebrae in length.

The overall function of the system filters approximately liters of fluid a day from renal blood flow which allows for toxins, metabolic waste products, and excess ion to be excreted while keeping essential substances in the blood. The kidney regulates plasma osmolarity by modulating the amount of water, solutes, and electrolytes in the blood.
The urinary system maintains blood homeostasis by filtering out excess fluid and other substances from the bloodstream and secreting waste. The renal system, which is also called the urinary system, is a group of organs in the body that filters out excess fluid and other substances from the bloodstream. The purpose of the renal system is to eliminate wastes from the body, regulate blood volume and pressure, control levels of electrolytes and metabolites, and regulate blood pH. The renal system organs include the kidneys, ureters, bladder, and urethra. Metabolic wastes and excess ions are filtered out of the blood, along with water, and leave the body in the form of urine. Components of the renal system : Here are the major organs of the renal system.
Renal system , in humans , organ system that includes the kidneys , where urine is produced, and the ureters , bladder , and urethra for the passage, storage, and voiding of urine. In many respects the human excretory, or urinary, system resembles those of other mammalian species, but it has its own unique structural and functional characteristics. The terms excretory and urinary emphasize the elimination function of the system. The kidneys, however, both secrete and actively retain within the body certain substances that are as critical to survival as those that are eliminated. The system contains two kidneys, which control the electrolyte composition of the blood and eliminate dissolved waste products and excess amounts of other substances from the blood; the latter substances are excreted in the urine, which passes from the kidneys to the bladder by way of two thin muscular tubes called the ureters. The bladder is a sac that holds the urine until it is eliminated through the urethra.
Discuss the physiology of how the renal and urinary systems work. Introduction. The urinary system is comprised of the kidneys, ureters, urinary.
Urinary System Anatomy and Physiology
Like all body systems, the renal system goes through an inevitable decline in its function as the body ages, but in the absence of disease it will function adequately throughout life. The functions of the renal system include removal of waste products; regulation of blood volume, blood pressure and red blood cells; and balancing of electrolytes and blood pH. Renal function starts to gradually decline after the third decade of life but, in the absence of disease, the renal system is able to fulfil its role throughout life. In spite of this, many anatomical and physiological changes mean older people are prone to issues such as polyuria, nocturia and incontinence.
The urinary system consists of two kidneys, two ureters, a urinary bladder , and a urethra. The kidneys alone perform the functions just described and manufacture urine in the process, while the other organs of the urinary system provide temporary storage reservoirs for urine or serve as transportation channels to carry it from one body region to another. The kidneys, which maintain the purity and constancy of our internal fluids, are perfect examples of homeostatic organs. The urethra is a thin-walled tube that carries urine by peristalsis from the bladder to the outside of the body.
A good knowledge of renal physiology is essential to the understanding of many disease states. The purpose of the book is to set out the principles of renal physiology and normal renal function. Now in its 30 th year of continuous publication, this new edition offers a logical progression through renal physiology and pathophysiology. In addition, the anatomy, physiology, pharmacology and pathology of the kidney are covered — making it highly suitable for system based courses.
The kidneys are two reddish-brown bean-shaped organs found in vertebrates.
Кому вы его продали. Тучный немец в полном недоумении сидел на кровати. Надежды на романтический вечер рушились по непонятной причине. - Was passiert? - нервно спросил. - Что происходит. Беккер не удостоил его ответом. - На самом деле я его не продала, - сказала Росио.
Она металась между дверцами кабинок и рукомойниками. Потеряв ориентацию, двигалась, вытянув перед собой руки и пытаясь восстановить в памяти очертания комнаты. Споткнулась о мусорный бачок и едва не наткнулась на кафельную стенку. Ведя рукой по прохладному кафелю, она наконец добралась до двери и нащупала дверную ручку. Дверь отворилась, и Сьюзан вышла в помещение шифровалки.
