- Filtration, Reabsorption, Secretion: The Three Steps of Urine Formation
The kidneys filter unwanted substances from the blood and produce urine to excrete them. There are three main steps of urine formation: glomerular filtration, reabsorption, and secretion. These processes ensure that only waste and excess water are removed from the body. Each kidney contains over 1 million tiny structures called nephrons.
Gross Anatomy of the Kidney
The nephron of the kidney is involved in the regulation of water and soluble substances in blood. A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Its function is vital for homeostasis of blood volume, blood pressure, and plasma osmolarity. It is regulated by the neuroendocrine system by hormones such as antidiuretic hormone, aldosterone, and parathyroid hormone. The basic physiology of a nephron within a kidney : The labels are: 1.

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. In this video, Dr. The left kidney is located at about the T12 to L3 vertebrae, whereas the right is lower due to slight displacement by the liver.

Filtration, Reabsorption, Secretion: The Three Steps of Urine Formation
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.
Он знал: все уверены, что он ушел. В шуме, доносившемся из-под пола шифровалки, в его голове звучал девиз лаборатории систем безопасности: Действуй, объясняться будешь. В мире высоких ставок, в котором от компьютерной безопасности зависело слишком многое, минуты зачастую означали спасение системы или ее гибель.
Как бы там ни было, Стратмор знал, что Хейла можно будет всегда ликвидировать в случае необходимости. - Решайтесь, приятель! - с издевкой в голосе сказал Хейл. - Мы уходим или нет? - Его руки клещами сжимали горло Сьюзан.
