The digestive system breaks down food into smaller molecules for absorption and energy, involving organs like the mouth, esophagus, stomach, small and large intestines, and accessory organs like the liver and pancreas.
Here's a more detailed explanation:
What is the digestive system?
The digestive system, also known as the gastrointestinal (GI) tract or digestive tract, is a series of organs that work together to break down food into smaller molecules that the body can absorb and use for energy, growth, and repair.
It also eliminates waste products that are not absorbed.
Key Organs of the Digestive System:
Mouth: Where food is initially broken down by chewing and mixed with saliva, which contains enzymes that start the digestion of carbohydrates.
Esophagus: A tube that carries food from the mouth to the stomach.
Stomach: A muscular organ that churns food and mixes it with gastric juices, further breaking down proteins.
Small Intestine: A long, coiled tube where most nutrient absorption occurs. It has three sections: the duodenum (where further digestion occurs), the jejunum, and the ileum.
Large Intestine: Absorbs water and forms solid waste (f***s).
Re**um: Stores f***s until they are eliminated.
A**s: The opening through which f***s are eliminated.
Accessory Organs: These organs help with digestion but are not part of the GI tract:
Liver: Produces bile, which helps in the digestion of fats.
Gallbladder: Stores and concentrates bile.
Pancreas: Produces enzymes that help digest carbohydrates, fats, and proteins, as well as hormones that regulate blood sugar.
Salivary Glands: Produce saliva, which contains enzymes that start the digestion of carbohydrates.
