Digestive apparatus

The digestive apparatus is a set of organs and tissues that ensure the digestion and assimilation of food in the human body. It consists of several systems such as digestive, respiratory, circulatory and nervous.

The digestive system consists of the stomach, intestines and pancreas. The stomach is the initial part of the digestive tract where food is crushed and mixed with gastric juice. The intestine is a long tube that extends from the stomach to the anus. This is where the final digestion of food and absorption of nutrients into the blood occurs. The pancreas produces enzymes necessary for the breakdown of proteins, fats and carbohydrates.

The respiratory system ensures that oxygen enters the body and carbon dioxide is removed. It consists of the lungs, bronchi, trachea and larynx. The lungs are the main respiratory organs where gas exchange occurs between air and blood. The bronchi branch into small bronchioles, which end in alveoli, where gases are exchanged between blood and air. The larynx serves to conduct air into the trachea and protect the airways.

The circulatory system transports nutrients and oxygen to tissues and organs, and also removes metabolic waste products. It consists of the heart, blood vessels and blood cells. The heart is the main circulatory organ that pumps blood throughout the body. Blood vessels are tubes through which blood flows from the heart to the organs and back. Blood cells perform the function of transporting oxygen and nutrients, as well as removing metabolic products.

The nervous system provides communication between all organs and systems of the body, and also regulates their work. It consists of the brain and spinal cord, nerves and ganglia. The brain is responsible for coordination of movements, perception of information, decision making and other functions. The spinal cord transmits signals from the brain to the peripheral nerves and back. Nerves are thin fibers that transmit electrical impulses between cells.

General description of the digestive apparatus

***The digestive apparatus*** is a collection of organs involved in the digestion process and their ducts. During digestion, a number of processes occur, including the digestion of food and the absorption of nutrients through the intestinal wall. One of the main jobs of the gastrointestinal (GI) tract is to extract maximum nutritional value from the food we eat. It is important to understand that each organ has its own unique functions and affects the digestion process. In the article we will look at the main organs of the digestive system, their functions, location and interaction with each other. We will also look at the features of digestion in different species of animals and humans.
