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 help keep extracellular fluid from becoming too dilute or concentrated with respect to the solutes carried in the fluid. Regulation of ion concentrations.

Kidney Overview

The kidneys are a pair of bean-shaped organs that are found high in the back of the abdominal cavity, just below the rib cage; one on either side of the spine. The right kidney is slightly lower than the left because of the position of the liver. Adult kidneys measure approximately 10 to 12cm in length and 5 to 7 cm in width, and weigh approximately g. If you were to cut a kidney in half you would see that it is divided into a dark outer area the cortex and an inner lighter-coloured area the medulla. Within the medulla there are between 10 and 18 renal pyramids; triangular structures which have a striped appearance. They have this appearance because of the renal tubules and associated blood vessels. The renal cortex and the pyramids make up the renal parenchyma.

There have never been sufficient kidney donations to provide a kidney to each person needing one. In this video, Dr. The paired 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. The left kidney is located at about the T12 to L3 vertebrae, whereas the right is lower due to slight displacement by the liver. Upper portions of the kidneys are somewhat protected by the eleventh and twelfth ribs Figure

Figure 1. Kidneys filter the blood, producing urine that is stored in the bladder prior to elimination through the urethra. The kidneys , illustrated in Figure 1, are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. The adrenal glands sit on top of each kidney and are also called the suprarenal glands. Kidneys filter blood and purify it. All the blood in the human body is filtered many times a day by the kidneys; these organs use up almost 25 percent of the oxygen absorbed through the lungs to perform this function. Oxygen allows the kidney cells to efficiently manufacture chemical energy in the form of ATP through aerobic respiration.
