The excretory system is a close partner with both the circulatory and endocrine system. The circulatory system connection is obvious. Blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system.

A nephron is the basic unit of structure in the kidney. A nephron is used separate to water, ions and small molecules from the blood, filter out wastes and toxins, and return needed molecules to the blood. The nephron functions through ultrafiltration.

Why are the kidneys important? Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium—in your blood.

The Human Excretory System | Back to Top. The urinary system is made-up of the kidneys, ureters, bladder, and urethra. The nephron, an evolutionary modification of the nephridium, is the kidney's functional unit.

During kidney transplant surgery, the donor kidney is placed in your lower abdomen. Blood vessels of the new kidney are attached to blood vessels in the lower part of your abdomen, just above one of your legs. The new kidney's urine tube (ureter) is connected to your bladder.

Where Are the Kidneys and How Do They Function? There are two kidneys, each about the size of a fist, located on either side of the spine at the lowest level of the rib cage. Each kidney contains up to a million functioning units called nephrons.

Your kidneys are fist-sized organs shaped like beans that are located at the back of the middle of your trunk, in the area called your flank. They are under the lower part of your ribcage on the right and left sides of your backbone.

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.

The renal system eliminate wastes from the body, controls levels of electrolytes and metabolites, controls the osmoregulation of blood volume and pressure, and regulates blood pH. The renal system organs include the kidneys, ureter, bladder, and urethra. Nephrons are the main functional component of the kidneys.

The renal cortex, renal medulla, and renal pelvis are the three main internal regions found in a kidney. Nephrons, masses of tiny tubules, are largely located in the medulla and receive fluid from the blood vessels in the renal cortex.
