After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood. The kidney and urinary systems help the body to get rid of liquid waste called urea. Urea is produced when foods containing protein such as meat, poultry, and certain vegetables are broken down in the body.

Urinary System Anatomy and Physiology

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

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. This 5 th edition has been extensively revised and features a wealth of new and widely accepted information about kidney function.

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 kidneys are encased in complex layers of fascia and fat. They are arranged as follows deep to superficial :.


Discuss the physiology of how the renal and urinary systems work. Introduction. The urinary system is comprised of the kidneys, ureters, urinary.


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.

Anatomy and Function of the Urinary System

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.

The kidneys are two reddish-brown bean-shaped organs found in vertebrates. Each kidney is attached to a ureter , a tube that carries excreted urine to the bladder. The nephron is the structural and functional unit of the kidney.

 Сьюзан. Она была потрясена. Прямо перед ней во всю стену был Дэвид, его лицо с резкими чертами. - Сьюзан, я хочу кое о чем тебя спросить.

The Renal System

 Она сказала, колымагой. - Колымагой. - Ну да, это ночной рейс в выходные - Севилья, Мадрид, Ла-Гуардиа.

Лампочки в конце коридора не горели, и на протяжении последних двадцати метров можно было различать только смутные силуэты. Женщина с кровотечением… плачущая молодая пара… молящаяся маленькая девочка. Наконец Беккер дошел до конца темного коридора и толкнул чуть приоткрытую дверь слева. Комната была пуста, если не считать старой изможденной женщины на койке, пытавшейся подсунуть под себя судно. Хорошенькое зрелище, - подумал Беккер.

Войдя, Дэвид увидел мигающую лампочку автоответчика. Слушая сообщение, он выпил почти целый пакет апельсинового сока. Послание ничем не отличалось от многих других, которые он получал: правительственное учреждение просит его поработать переводчиком в течение нескольких часов сегодня утром. Странным показалось только одно: об этой организации Беккер никогда прежде не слышал. Беккер позвонил одному из своих коллег: - Тебе что-нибудь известно об Агентстве национальной безопасности.

 Мне нужно кольцо, - холодно сказал. - Кто вы такой? - потребовала. Беккер перешел на испанский с ярко выраженным андалузским акцентом: - Guardia Civil. Росио засмеялась.
