Answer: The outer portion of the kidney that contains glomeruli is the renal cortex. It is within this region that the majority of the filtration units, known as glomeruli, are located. The glomeruli, together with the tubules, are responsible for the kidney's filtration function and the formation of urine.
Step-by-step explanation:
The outer portion of the kidney that contains glomeruli is called the renal cortex.
Here's an explanation to support the answer:
1) Renal cortex: The kidney is made up of various layers and regions, each with specific functions. The renal cortex is the outer region of the kidney, located just beneath the kidney's protective capsule. It is the site where the majority of glomeruli are found.
2) Glomeruli: Glomeruli are tiny, ball-shaped clusters of capillaries within the kidney. They play a crucial role in the process of filtration, which is a key function of the kidney. Each glomerulus is surrounded by a structure called Bowman's capsule, and together they form a unit known as the renal corpuscle. The renal corpuscle is responsible for filtering waste products, excess water, and other substances from the blood to form urine.
3) Location of glomeruli: Within the kidney, the renal cortex contains numerous nephrons, which are the functional units responsible for filtering blood and forming urine. Each nephron consists of a glomerulus and its associated tubules. The glomeruli are situated in the renal cortex, while the tubules extend into the deeper layer of the kidney called the renal medulla.
