Which of the following is a primary function of the digestive system?
Answer Details
The primary function of the digestive system is absorption of nutrients.
When we eat food, our digestive system breaks it down into smaller molecules, such as proteins, carbohydrates, and fats. These molecules are then absorbed by the small intestine and transported into the bloodstream.
Absorption is the process that allows the body to take in essential nutrients, vitamins, and minerals from the food we eat. These nutrients are important for growth, energy production, and overall body functioning. After absorption, the nutrients are carried throughout the body by the bloodstream, providing nourishment to cells and tissues. This process ensures that our body receives the necessary building blocks to maintain proper function and carry out essential processes.
So, while the other options listed (regulation of body temperature, oxygen transport, and production of hormones) are also important functions of the body, the primary function of the digestive system is the absorption of nutrients from the food we consume.
