7 Major Organ Systems: Functions and Connections instituteofhumananatomy.com Nov 23, 2025 10 facts
claimExamining the human body in three dimensions allows students to observe how the nervous, digestive, and circulatory systems interact within an actual anatomical setting.
claimThe human body relies on seven major organ systems to function effectively: the circulatory, nervous, respiratory, digestive, urinary, musculoskeletal, and endocrine systems.
claimThe digestive system is composed of the gastrointestinal (GI) tract, which is a continuous tube from the mouth to the anus, and accessory organs that produce enzymes and juices necessary for digestion.
claimThe circulatory system supports the digestive system by carrying absorbed nutrients through capillaries to the liver via the hepatic portal vein for distribution throughout the body.
claimThe digestive system utilizes hormones like gastrin and secretin, which coordinate with insulin to manage nutrient absorption.
claimAfter eating, the human digestive system breaks down carbohydrates into glucose, which the circulatory system then transports into the bloodstream.
referenceThe circulatory system delivers oxygen and nutrients to cells, the nervous system controls responses and coordination, the respiratory system ensures gas exchange, the digestive system processes food, the urinary system removes waste, the musculoskeletal system provides movement and support, and the endocrine system regulates processes using hormones.
claimDuring physical exertion, the human digestive system temporarily reduces activity to redirect blood flow to critical areas such as the brain and muscles.
claimThe circulatory system supports the digestive system by transporting nutrients absorbed from food to cells.
claimThe digestive system functions to convert food into energy and essential nutrients by breaking down complex molecules into simpler compounds used for energy, growth, and repair.

claimThe 11 systems of the human body are the integumentary system, skeletal system, muscular system, endocrine system, cardiovascular (circulatory) system, lymphatic (immune) system, respiratory system, digestive system, urinary system, reproductive system, and nervous system.
claimThe digestive system consists of a gastrointestinal tract (a tube extending from the mouth to the anal canal) and accessory digestive organs.
claimThe digestive system consists of a gastrointestinal tract (a tube comprising the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anal canal) and accessory digestive organs (tongue, salivary glands, pancreas, liver, and gallbladder) that assist with mechanical and chemical food breakdown.
