- One bronchus enters each lung. Each bronchus branches out into smaller tubes called bronchioles. Air travels through these bronchioles. At the end of the bronchioles, the air enters one of the many millions of alveoli where gaseous exchange takes place.

What Are the Lungs and Respiratory System? The lungs and respiratory system allow us to breathe. They: Bring oxygen into our bodies (called inspiration, or inhalation). Send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration. How Do the Lungs and Respiratory System Work?

Function of the Respiratory System
Respiratory System for Children: Respiration is a natural phenomenon that allows taking in oxygen and eliminating carbon dioxide. All cells need a constant supply of oxygen in order to live. The air we inhale is made up of a mixture of gases.
What is the Main Function of the Respiratory System
What is oxygen?Oxygen (O2) is an invisible gas, which is part of the air and is used for life on planet earth. We incorporate it through the respiratory system. It helps transform the food you eat into energy. Oxygen is more abundant in the air that enters the lungs. During this process, another gas is generated, carbon dioxide (CO2), which is a waste product and must be removed from the body. It is most abundant in the air that comes out of the lungs.
How Breathing Works: Explanation for Children
The respiratory system is made up of various organs and vessels that participate in the breathing process. Some organs of the respiratory system are located within what is called the thorax, which is limited by the ribs and the diaphragm. The respiratory tracts are the conduits through which the air circulates. They are divided into: Upper and Lower Respiratory Tracts 1. Upper Respiratory Tracts:They are made up of the nasal cavity, pharynx, and larynx. 2. Lower Respiratory Tracts: They are m...
Breathing does not depend on our will; it is an involuntary and automatic process. Where does the air we breathe go? We are going to explain the Respiratory System for Children. Air enters through the nose or mouth. It passes through the throat, where the pharynx and larynx are, into the trachea. The trachea then divides in two tubes called bronchi...
Nostrils
The nostrils are the cavities inside the nose. In them, there are fine hairs and mucus. The function of the nostrils is to filter and heat the air that enters, blocking dust and other particles from entering the body. Also read: Five Sense Organs for Kids and Students
Pharynx
This organ located in the neck, it is part of both the respiratory system and the digestive system. Air and food pass through this cavity. That is why it works in conjunction with the larynx, controlling the opening and closing of the airways towards the trachea and the digestive tract towards the esophagus.
Larynx
It is a tube that carries air from the nose to the windpipe. The larynx contains the vocal cords, which move when air passes, allowing the emission of sounds, our voice. It has a “cap” called the epiglottis that closes off access to the airways while food is sent up the digestive tract.
Where are the Lungs located in the Body?
What are the Lungs? The lungs are two soft, pinkish organs with a texture similar to that of a sponge. The left lung is slightly smaller than the right one. It leaves some extra space for the heart. The air that enters through the nostrils reaches the lungs. It does not arrive cold, but it gets warmer on its way.
Respiratory System: Lungs Function
The lungs take up much of the space inside our chest (thorax). They are protected by the rib cage. This “cage” is formed by the ribs, and it surrounds the lungs to keep them safe. Below the lungs there’s the diaphragm. It is a muscle that alternately rises and drops during the breathing process.
Diaphragm Function in Respiratory System
The diaphragm is a dome-shaped muscle that separates the thoracic cavity from the abdominal cavity. By contracting and relaxing, it allows the chest to expand and shrink. When we breathe in, the diaphragm lowers, allowing air to enter the lungs. And when we exhale, it rises, favoring the expulsion of air filled with carbon dioxide.
General Information of the Respiratory System The respiratory system works in conjunction with the circulatory system. It is one of the body’s nutritional systems. Oxygen from the pulmonary alveoli enters the blood through small capillaries. From there, it is transported to the heart, from where it is sent to all the rest of the human body. In reve...
The true respiration happens in the cells: The oxygen of the air that you inhale through the nostrils, reaches the lungs and from there it goes into the blood. It enters the tiny blood vessels and travels to every inch of your body. At the same time, carbon dioxide travels from the blood into the alveoli to be removed. The carbon dioxide that is pr...
The functions of the human respiratory system are as follows: Inhalation and Exhalation. The respiratory system helps in breathing (also known as pulmonary ventilation.) The air inhaled through the nose moves through the pharynx, larynx, trachea and into the lungs. The air is exhaled back through the same pathway.

The respiratory system is the body’s way of breathing in oxygen and breathing out carbon dioxide. Insects breathe through holes in the sides of their bodies. Fish and young amphibians have organs called gills to take in oxygen from water.
