Nephron Structure A Level
Fig. 1 - The general structure of the nephron and its constituting regions. Various blood vessels are associated with different regions of the nephron. These events progressively occur at every level along the loop of Henle. As a result, the filtrate loses water as it goes through the descending limb, and its water content gets to its

The location and structure of a nephron. There is also a network of blood vessels associated with each nephron. Within the Bowman's capsule of each nephron is a structure known as the glomerulus. Each glomerulus is supplied with blood by an afferent arteriole which carries blood from the renal artery. The capillaries of the glomerulus rejoin to form an efferent arteriole
The afferent arteriole brings blood to the glomerulus, and the efferent arteriole removes blood from the nephron.The proximal convoluted tubule comes next and is involved in the selective reabsorption of water, ions and all organic nutrients.The loop of Henle consists of a descending limb where there is further reabsorption of water, and an
Nephron is a basic microscopic structural and functional unit of the Kidney. Nephrons work on the principle of ultrafiltration for extracting and reabsorption of molecules.

Kidney nephron structure. The kidneys are responsible for osmoregulation regulating the water content of the blood. excretion the removal of metabolic waste and excess substances from the blood. The internal structure of the kidney includes the outer renal cortex. the inner renal medulla. the renal pelvis at the centre of the kidney where urine is funnelled into the ureter
Unit 3 A Level Biology Gross structure of the kidney The renal artery supplies oxygen and glucose and has a high concentration of urea. The nephron is the functional unit of the kidney. The glomerulus, Bowman's capsule, proximal convoluted tubule and distal convoluted tubule are located in the
Kidney Structure The kidneys are made up of millions of nephrons, which act as tiny filtering units. The cortex is the dark outer layer.This has a high density of capillaries as it is the site of blood filtration. The medulla is the lighter area inside the cortex.This contain nephron tubules which make the kidney pyramids and collecting ducts. The pelvis is the innermost part of the kidney.

A nephron is the unit of structure and function in the kidney. Each nephron is a coiled tube held together by a tough fibrous connective tissue. In humans, a healthy adult has 1 to 1.5 million nephrons in each kidney, functioning together to filter blood from all its impurities. They also regulate blood pressure, control electrolytes, and
