80% of all heart failure patients are 65 years and older. When the heart muscle weakened‚ it will fail to pumps blood‚ then the circulation will be less effectively‚ that leads to increase hydrostatic pressure in capillaries‚ the fluid will accumulate in interstitial space. When the volume of fluid exceeds the lymphatic system ability to drainage‚ it will form edema. Most swelling occur

The digestive system helps the body to break down food into smaller molecules to help the body to absorb the nutrients it needs and lets the body digest the energy from the food. Enzymes chemically react with the food and act as a catalyst to speed the process up. The body needs each food group from different reason: Dairy provides calcium-keeps bones strong. Carbohydrates for quick release of energy. Fats provide a slow release of energy throughout the day. Protein builds and repairs muscle.

mechanical and chemical receptors that control digestive activity are located in the walls of the GI tract organ. (854) 2) The chemical and mechanical processes of food breakdown are called digestion. (852-853) 3) The function of the hepatic portal circulation is to collect absorbed nutrients for metabolic processing and storage. (881) 4) When we ingest large molecules such as lipids‚ carbohydrates‚ and proteins‚ they must undergo catabolic reactions whereby enzymes split these molecules.
