What do the kidneys do?
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. They serve the body as a natural filter of the blood and remove wastes that are excreted through the urine. They are also responsible for the reabsorption of water, glucose, and amino acids, and will maintain the balance of these molecules in the body. In addition, the kidneys produce hormones including calcitriol, erythropoietin, and the enzyme renin, which are involved in renal and hemotological physiological processes. The kidneys are a pair of bean-shaped, brown organs about the size of your fist.
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 nephrons found in the kidneys mesonephros of amphibians and most fish, and in the late embryonic development of more advanced vertebrates, are only slightly more advanced in structure. The most advanced nephrons occur in the adult kidneys, or metanephros , of land vertebrates, such as reptiles, birds, and mammals. Each nephron in the mammalian kidney is a long tubule, or extremely fine tube, about 30—55 mm 1. At one end this tube is closed, expanded, and folded into a double-walled cuplike structure.
The kidneys are a pair of bean-shaped organs present in all vertebrates. They remove waste products from the body, maintain balanced electrolyte levels, and regulate blood pressure. The kidneys are some of the most important organs. The Ancient Egyptians left only the brain and kidneys in position before embalming a body, inferring that the held a higher value. In this article, we will look at the structure and function of the kidneys, diseases that affect them, and how to keep the kidneys healthy. The right kidney is generally slightly smaller and lower than the left, to make space for the liver. A tough, fibrous renal capsule surrounds each kidney.

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. Urea is carried in the blood to the kidneys. This is where it is removed, along with water and other wastes in the form of urine.
The kidneys are among the most vital organs of the human body. Malfunction of the kidneys can lead to serious illness or even death. Each kidney has a very complex structure and function. They have two important functions namely: to flush out harmful and toxic waste products and to maintain balance of water, fluids, minerals and chemicals i. The kidney produce urine by removing toxic waste products and excess water from the body.

They are embedded in a groove, the renal fossa , which consists of the Musculus psoas major and the Musculus quadratus lumborum. The left kidney lies between the level of the 11th rib and the 3rd lumbar vertebra. Due to the size of the liver , the right kidney lies in a slightly lower position, beginning at the level of the 12th rib and extending to the lower edge of the 3rd lumbar vertebra. Physiologically, the kidneys have moving flexibility of about 3—4 cm, depending on the posture of the body and the movement of the diaphragm during breathing, because the kidneys are not firmly attached to the back of the abdominal wall. The kidneys are bean-shaped and red-brown.
Kidney and its Function
Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs. Regulation of osmolarity.
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.
И они еще решили оставить меня здесь на ночь. Беккер огляделся: - Понимаю. Это ужасно. Простите, что я так долго до вас добирался.

Меган, - сказал он печально. - Я полагаю, что у вашей подруги есть и фамилия. Беккер шумно вздохнул. Разумеется.
Беккер склонился над. - Вам плохо. Клушар едва заметно кивнул: - Просто… я переволновался, наверное. - И замолчал.
Немец называл эту женщину… Беккер слегка потряс Клушара за плечи, стараясь не дать ему провалиться в забытье. Глаза канадца на мгновение блеснули. - Ее зовут… Не отключайся, дружище… - Роса… - Глаза Клушара снова закрылись. Приближающаяся медсестра прямо-таки кипела от возмущения. - Роса? - Беккер сжал руку Клушара. Старик застонал.
