See the below image for the Kidney drawing diagram. Labeled Diagram of the Human Kidney The human kidneys house millions of tiny filtration units called nephrons, which enable our body to retain the vital nutrients, and excrete the unwanted or excess molecules as well as metabolic wastes from the body. In addition, they also play an important role in maintaining the water balance of our body.
Labeled Diagram of the Human Kidney. The renal medulla comprises a set of 8-18 conical structures called renal pyramids that are surrounded by the cortex. Portions of the cortex between two adjacent pyramids are termed as renal columns. Spread in these pyramids and the cortex, are the functional units callednephrons.
Weight of an adult kidney: Males: 125-170 g. Females: 115-155 g. Located in the abdominal cavity, kidneys are the most efficient filters. They are an important component of the human excretory system, and help the body retain essential molecules and get rid of the unwanted ones.
