Final answer:
The digestive system processes include secretion for the production of digestive enzymes, absorption for the movement of nutrients across the GI tract epithelium, and elimination of wastes which involves defecation.
Step-by-step explanation:
The student is matching processes of the digestive system with their corresponding functions.
- Producing and releasing digestive enzymes - Secretion
- Involves the process of defecation - Elimination of wastes
- Nutrients move across GI tract epithelium - Absorption
The digestive system is responsible for the digestion of food, absorption of nutrients, and elimination of waste. Digestion includes both mechanical and chemical processes to break down food into absorbable components. The lining of the GI tract secretes digestive enzymes and absorbs nutrients, while peristalsis moves the undigested components towards the large intestine for defecation. Understanding these processes is important in comprehending how the body obtains and uses nutrients from food, and also how waste materials are processed and eliminated.
The digestive system has three main functions: digestion of food, absorption of nutrients, and elimination of solid food waste. Digestion is the process of breaking down food into components the body can absorb. It consists of two types of processes: mechanical digestion and chemical digestion.
