Interconnectedness of the Human Body Systems: Digestive and Circulatory Systems

• The digestive system breaks down food and absorbs nutrients for energy and building blocks for cells.
• The circulatory system transports oxygen, nutrients, and removes waste products.
• The respiratory system takes in oxygen and removes carbon dioxide.
• The musculoskeletal system provides support and movement for efficient function of other systems.
• The nervous system controls and coordinates the functions of all body systems.
• The digestive system includes the mouth, esophagus, stomach, pancreas, small intestine, liver, gallbladder, large intestine, rectum, and anus.
• Absorption mainly occurs in the small intestine, specifically the walls of the jejunum and ileum.
• Accessory organs include the liver, gallbladder, and pancreas, which produce bile and enzymes for digestion and absorption of fats, carbohydrates, and proteins.
• The circulatory system includes the heart, blood vessels, and capillaries for transporting oxygen, nutrients, and waste products.
• Interactions between the digestive system and other body systems include the transport of absorbed nutrients via the bloodstream to cells throughout the body, assistance of the diaphragm muscle in swallowing, and the nervous system's control of digestive functions.
• Diseases and dysfunctions of the digestive system include GERD, peptic ulcers, IBS, Crohn's disease, and celiac disease.
• The components of the circulatory system include the heart as a pump, arteries for carrying oxygenated blood away from the heart, veins for carrying deoxygenated blood back to the heart, and capillaries for exchanging oxygen, nutrients, and waste products with tissues.
