Arteriole of the Brain Substance

The medullary arteriole (renal arterioles) are small vessels that form a capillary network in the renal medulla. They ensure the delivery of oxygen and nutrients to the cells of the medulla.

The arterioles of the medulla begin from the renal arteries, which are branches of the abdominal aorta. They then branch into smaller arteries that penetrate the renal medulla. In the medulla, they form capillaries where the exchange of substances between blood and cells occurs.

The medulla capillaries contain many cells that perform various functions, such as filtering blood, producing hormones, and regulating pressure in the kidneys. If the arterioles of the medulla become damaged or narrowed, this can lead to disruption of the blood supply to the medulla and the development of various kidney diseases such as renal failure and glomerulonephritis.

To maintain the normal functioning of the renal medulla, it is necessary to monitor the condition of the arterioles of the medulla, as well as control blood pressure and cholesterol levels in the blood. This will help prevent the development of kidney disease and keep your kidneys healthy for many years.
