Yes, that's correct. In each nephron of the kidney, the efferent arteriole, which carries blood away from the glomerulus, divides to form a network of tiny blood vessels called the peritubular capillaries. These capillaries surround the tubular parts of the nephron and allow for the exchange of substances between the blood and the nephron. Here are the steps:

1. Blood enters the kidney through the renal artery, which branches off into smaller and smaller arteries until it reaches the level of the nephron.

2. Each nephron is supplied with blood by an afferent arteriole, which leads to the glomerulus, a network of tiny blood vessels or capillaries.

3. Within the glomerulus, the blood is filtered, and the filtrate, which contains waste products, water, and other small molecules, enters the tubular part of the nephron.

4. The remaining blood, now devoid of these small molecules, leaves the glomerulus through the efferent arteriole.

5. The efferent arteriole then divides to form the peritubular capillaries, which surround the tubular parts of the nephron.

6. As the filtrate moves through the tubules of the nephron, substances that the body needs to retain, such as glucose, amino acids, and certain ions, are reabsorbed back into the blood through the peritubular capillaries.

7. The remaining filtrate, now concentrated into urine, continues its journey out of the nephron and eventually leaves the body through the urethra.
