• Nutritional Components Nutritional components include: - Water - Vitamins - Salt - Carbohydrate complexes - Proteins - Lipids - Fiber We have various coordinated devices to carry out processes related to nutritional functions. First, since food is not directly available for the body's cells, it must be processed: the nutrients contained within must be broken down into simpler substances. Then, these substances need to be transported throughout the body to reach all tissues. --- NEXT IMAGE --- The digestive system extracts the nutrient components from solid and liquid foods, making them available for the body. Through the digestive tract, these components are simplified. That is, via digestion, large molecules such as proteins, lipids, and carbohydrates are broken down into simpler molecules (nutrients, energy sources). The digestive system achieves this thanks to digestive enzymes. After this breakdown, these substances are ready to be absorbed by cells and participate in the body's nutrition process. On the other hand, the respiratory system takes in gases from the environment through breathing. Oxygen enters the body, maintaining respiration, and carbon dioxide is expell...
