What is the Digestive system in biology
Your digestive system is made up of the gastrointestinal tract. The pancreas, liver, and gall bladder play important roles in your digestive system.
The gastrointestinal tract starts from the mouth and ends at the anus, although in the middle it’s also connected to many other organs. This includes your mouth, small intestine, esophagus, large intestine, and stomach.
Your liver, gall bladder, pancreas are important and strong parts of your digestive system.
The small intestine present in your body divides into three parts in the process of digestion, the first part is the duodenum, the second part is the midgut and the third is the ileum.
In your intestine (cecum) i.e the sac of the large intestine is present, and in addition, there is also the colon and rectum.
The gastrointestinal tract contains gut flora and microorganisms that help in the digestion of food
The nervous system, blood vessels, hormones, bacteria, and some other internal organs also help digest food or liquids.
What is the Circulatory system
The Circulatory system transports nutrition, metabolic products, and respiratory gases in the human body. In the human body blood always remains in the closed cardiovascular system, Which is made of blood. Arteries pump blood away from the heart due to high pressure during the heart pumping process.
Your arteries divide into smaller arteries that branch into a network of peak cells near thin walls. Its function is to disperse gases and nutrients.
In this process, blood is first carried from the heart to the lungs and then oxygen is taken from there and carbon dioxide is released. This is followed by the supply of oxygen and nutrients to the heart and the rest of the body through blood.
How your digestive system works
When you put the first bite in your mouth, then the process of digestion starts from there.
As soon as the first bite is placed in the mouth, then it’s first divided into small pieces and then the nutrients are taken out from the food and sent to the whole body. Your large intestine stores important elements of food and then the remaining waste is thrown.
What is the process of the digestive system
- Mouth: First of all, as soon as you put food in your mouth, it mixes with saliva and then goes to the esophagus.
- Esophagus: The food you eat moves towards your stomach through the esophagus
- Stomach: To digest food, the glands in the stomach get the important enzymes in your food.
- Pancreas: It separates proteins, carbohydrates, and fats from your food and makes digestive juices, and passes them to the small intestine.
- Liver: It helps in producing digestive juices, due to which it becomes easier to digest fats. Digestive juice first goes to the bile ducts and then gets stored in the liver. and goes into the small intestine as needed
- Gallbladder: It stores digestive juices after eating food and goes into the small intestine as soon as you start eating
- Small Intestine: This mixes food and digestive juices together and then separates carbs, proteins, and fats. Bacteria in the small intestine make enzymes that digest carbohydrates. The small intestine delivers water to the blood vessels as needed and absorbs nutrients as well.
- Large Intestine: It carries water through the gastrointestinal tract to the blood vessels. This type of bacteria is found in this intestine, which apart from nutrients, also makes vitamins. However, after this the remaining food becomes stool and then it reaches the rectum.
- Rectum: Food that enters the rectum from the large intestine is then passed out of your body through the anus.
How does the circulatory system work with the digestive system
The digestive system’s blood flow get increased after eating foods, the digestive system needs a circulatory system to transfer particles that have been absorbed to the liver so that’s the reason for this increase.
The liver uses these absorbed particles that the circulatory system brings to make glycogen and proteins to store them inside itself. Unlike other organs, gastrointestinal blood does not return directly to the heart, but first passes through the liver and then flows into the heart. After a while, the blood flow returns to normal.
