The organ system primarily involved in the digestion and metabolism of macronutrients—carbohydrates, proteins, and fats—is the digestive system. This system includes organs such as the mouth, stomach, and intestines, where these macronutrients are broken down into smaller units for absorption. The liver also plays a crucial role in processing and distributing these nutrients throughout the body. Overall, the digestive system works in conjunction with the circulatory system to ensure that macronutrients are utilized effectively for energy and growth.
