This presentation discusses the process of excretion in the human body. It contains the following key points: 1. Kidneys are the main organs that remove waste from the blood and expel it from the body in the form of urine. There are usually two kidneys in the human body. 2. The kidneys contain millions of filtering units called nephrons that remove waste from the blood to form urine. Urine is stored in the bladder and expelled through the urethra. 3. The kidneys play an important role in homeostasis by regulating the chemical composition of the blood and removing toxins.
