Which system is involved in breaking down food and absorbing nutrients?

• A. Endocrine system
• B. Circulatory system
• C. Digestive system
• D. Respiratory system

Answer: (C)

The digestive system is the correct choice because it is specifically designed for breaking down food into smaller, absorbable components and extracting essential nutrients that the body requires to function. This process begins in the mouth, where food is mechanically broken down by chewing and enzymatically broken down by saliva. It continues through the esophagus, stomach, and intestines, where various enzymes and digestive juices further disassemble food into its nutrient parts, such as carbohydrates, proteins, and fats. The digestive system then facilitates the absorption of these nutrients primarily in the small intestine, where they pass through the intestinal lining into the bloodstream to be transported to cells throughout the body. This intricate system allows the body to obtain energy and nutrients from the foods we consume, making it essential for overall health and wellness.
