The image shows the digestive system of a human body Stock Biology Diagrams The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages: the cephalic phase, the gastric phase, and the
The organs of the digestive system can be separated into two main groups: those forming the alimentary canal and the accessory digestive organs. Organs of the Alimentary Canal The alimentary canal, also called the gastrointestinal tract, is a continuous, hollow muscular tube that winds through the ventral body cavity and is open at both ends. The human digestive system refers to the organs that take in food and break them down. Digestion describes the complex process that enables the nutrients in food to enter the body and its cells.
Digestive System (Anatomy): How It Works Biology Diagrams
human digestive system, system used in the human body for the process of digestion.The human digestive system consists primarily of the digestive tract, or the series of structures and organs through which food and liquids pass during their processing into forms that can be absorbed into the bloodstream. The system also consists of the structures through which wastes pass in the process of Digestive System Function. Digestion is the complicated process of turning the food you eat into nutrients, which your body uses for energy, growth, and cell repair.
Learn about the organs, functions, and processes of the digestive system. Find out how food moves through your GI tract, how nutrients are broken down and absorbed, and how your body controls digestion. The GI tract begins to form early during the development of the human body, in the third week after fertilization. Around the 16 th day of development, the primitive gut is formed through invaginations of embryonic cells. The initial structures of the digestive system extend from the buccopharyngeal membrane to the cloacal membrane. What is the digestive system? Your digestive system is a group of organs that work together to digest and absorb nutrients from the food you eat. Digestion is a complicated process, and conditions and disorders can disrupt that process. Knowing how your digestive system works may help you keep it healthy and know when it may be time to get
