Kidney in vertebrates and some invertebrates, an organ maintaining water balance and excreting waste products. Primitive and embryonic kidneys consist of two series of specialized tubules that open into two collecting ducts, the Wolffian ducts (

Wolff’s duct). The more advanced kidney (metanephros) of adult reptiles, birds, and mammals is a paired, compact organ whose functional units, called nephrons, filter the initial urine from the blood, reabsorb water and nutrients, and excrete waste, producing the final urine that is excreted.

The kidneys of reptiles and birds are composed of many tiny lobes, which in birds are fused into three or more lobes. Collecting tubules from each lobe, they empty into a separate branch of the ureter. Reptiles have relatively few nephrons (3,000 to 30,000 in lizards), while birds have large numbers (about 200,000 in fowl, twice as many as in a mammal of comparable size).

Mammalian kidneys have a slightly granular outer part (cortex), containing glomeruli and convoluted tubules, and a smooth, somewhat striated inner part (medulla), containing the loops of Henle and collecting tubules. As the ureter enters the kidney, it enlarges and forms a cavity, the renal pelvis; urine passes into this pelvis from the collecting ducts. Nephrons are numerous (20,000 in mice).

In humans, the kidneys are about 10 centimeters long and are located under the diaphragm and behind the peritoneum. Each kidney contains 1,000,000–1,250,000 nephrons, which filter fully five-quarters of the water in the blood every 45 minutes, equivalent to 160 liters per day. Of this, only 1.5 liters are excreted; the remainder is reabsorbed by the nephrons.

Damaged kidneys secrete an enzyme called renin, which stimulates blood vessels to constrict. When the damage was initially caused by high blood pressure, the increase in pressure in the narrowed vessels causes more damage to the kidneys.Home Games & Quizzes History & Society Science & Technology Biographies Animals & Nature Geography & Travel Art & Culture Money Videos

Renal system in humans a system of organs that includes the kidneys, which produce urine, and the ureters, bladder, and urethra, which pass, store, and excrete urine.

In many respects, the human excretory, or urinary, system resembles that of other mammalian species, but it has its own unique structural and functional features. Conditions

The Human Body: Anatomy, Facts & Functions

Emphasize the elimination function of the system. However, the kidneys both secrete and actively retain certain substances that are as important for survival as those that are excreted.

The system includes two kidneys that control the composition of blood electrolytes and eliminate dissolved waste products and excess other substances from the blood; the latter substances are excreted in the urine, which passes from the kidneys to the bladder through two thin, muscular tubes called the ureters. The bladder is the bag in which urine remains expelled through the urethra.

The kidneys are reddish-brown, paired, bean-shaped organs, concave on one long side and convex on the opposite side. They are usually located high in the abdominal cavity, at the back wall, on both sides of the spine, between the levels of the 12th thoracic and third lumbar vertebrae, and outside the peritoneum, the membrane that lines the abdomen.

The long axes of the kidneys are aligned with the body axis, but the upper end of each kidney (pole) is tilted slightly inward toward the vertebral column (spine). In the center of the concave medial border is a deep vertical slit, the hilum, which leads to a cavity in the kidney called the renal sinus. The hilum is the point of entry and exit of the renal arteries and veins, lymphatic vessels, nerves, and the enlarged superior extension of the ureters. Most people have two kidneys, which are organs located in the back of the abdomen. The primary function of the kidneys is to filter the blood. They also remove waste and balance fluids in the body. Common kidney diseases include kidney disease, kidney infections, and kidney cysts.

Definition Of Kidney

Your kidneys filter all your blood once an hour – keeping what you need and getting rid of the rest.

The kidneys are two bean-shaped organs that filter blood. The kidneys are part of the urinary system.

Your kidneys filter about 200 liters of fluid a day – enough to fill a large bathtub. During this process, the kidneys remove waste that leaves the body as urine (pee). Most people pee about two liters a day. Your body reuses the remaining 198 liters of fluid.

The kidneys also help maintain the balance of body fluids (mainly water) and electrolytes. Electrolytes are essential minerals that include sodium and potassium.

People with diabetes or high blood pressure are most at risk of kidney problems. Accidents or trauma, such as car accidents or sports injuries, can also damage the kidneys.

Your kidneys perform many important functions. They cleanse toxins and waste from the blood. Common waste products include nitrogenous waste (urea), muscle waste (creatinine), and acid. They help the body remove these substances. Your kidneys filter about half a cup of blood per minute.

The adrenal gland sits on top of each kidney. It produces hormones, including cortisol, which helps the body respond to stress.

You can live with one kidney. Health care providers may remove one of the kidneys in cases of radical nephrectomy.

The kidneys are located just below the rib cage and behind the abdomen. Typically, one kidney is located on either side of the spine. The kidneys are located between the intestines and the diaphragm. The ureter connects each kidney to the bladder.

The kidney capsule consists of three layers of connective tissue, or fat, covering the kidneys. It protects the kidneys against injuries, increases their stability and connects the kidneys to the surrounding tissues.

The renal artery is a large blood vessel that controls blood flow to the kidneys. In most people, the kidneys pump just over 5 cups (1.2 liters) of blood per minute when they are at rest.

Kidney Infection: Causes, Symptoms, Diagnosis, And Treatment

The outer layer of the kidneys, where the nephrons (blood filtering units) begin. The renal cortex also produces the hormone erythropoietin (EPO), which helps produce red blood cells in the bone marrow.

The renal medulla is the inner part of the kidney. It contains most of the nephrons along with the glomeruli and renal tubules. The renal tubules drain urine into the renal pelvis.

These pyramid-shaped structures transport urine to the ureters. Dehydration and certain medications – especially nonsteroidal anti-inflammatory drugs (NSAIDs) – can damage the renal papilla.

This funnel-shaped structure collects urine and passes it through two ureters. Urine moves from the ureters to the bladder, where it is stored.

This vein is the main blood vessel that carries filtered blood from the kidneys and back to the heart. Each kidney has a renal vein.

The weight of the kidneys varies. Variations may include height, weight, age, body mass index (BMI) and location.

For men and people assigned male at birth, the weight of the right kidney can range from 1/5 to about 1/2 pound. (79 grams to 223 grams). Your left kidney may weigh anywhere from a little less than 1/5 to a little over 1/2 pound. (74 grams to 235 grams). Your kidneys can weigh anywhere from one tennis ball to four tennis balls.

For women and people assigned female at birth, the weight of the right kidney can range from just over 1/10 to 3/5 of a pound. (55 grams to 274 grams). Your left kidney may weigh anywhere from 3/20 to a little less than 3/5 of a pound. (67 grams to 261 grams). Your kidneys can weigh anywhere from one tennis ball to five tennis players
