matsmältningsvägarna
Matsmältningsvägarna, or the digestive system, is a complex network of organs and structures responsible for the breakdown, absorption, and elimination of food and waste materials in the body. It begins at the mouth, where mechanical digestion starts with chewing and the addition of saliva, which contains enzymes that begin the chemical breakdown of carbohydrates. The food then travels through the esophagus, a muscular tube that transports the bolus to the stomach via peristalsis.
The stomach is a J-shaped organ that mixes and breaks down food further with the aid of
The large intestine, or colon, absorbs water and electrolytes from the remaining waste material, forming feces.
