digestive and excretory
The digestive system is primarily responsible for taking in nutrients and breaking down food into absorbable components. It includes organs such as the mouth, stomach, and intestines, which facilitate digestion and nutrient absorption. The excretory system, particularly the kidneys and urinary tract, expels waste products and excess substances from the body. Together, these systems ensure that the body efficiently utilizes nutrients while eliminating waste.
