Human Respiratory Equipment and Its Functions – The human respiratory system consists of several interconnected parts. Explore the organs that make up the human respiratory system and their functions here.
The lungs are the most important human respiratory organ. In carrying out its functions, the lungs are also assisted by other components of the respiratory system, including the nose, trachea and respiratory muscles.
Human Respiratory Equipment and Its Functions
The human respiratory system consists of the upper and lower respiratory tract. Both have many organs with their respective functions.
Science Theme 2 Sub-theme 1 (Human Respiratory System)
The respiratory or respiratory system consists of a network of organs that help humans breathe. This includes the airways, lungs, and blood vessels.
The main parts of the respiratory system include the upper and lower respiratory tract. These parts contribute to each other in the movement of oxygen in the body and the elimination of gases such as carbon dioxide.
The respiratory system also helps remove metabolic waste products and regulates pH levels. Besides helping you breathe, some of the other functions of your respiratory system include:
The upper and lower respiratory tract work together to carry out the respiratory system, or the process of exchanging carbon dioxide and oxygen.
Respiratory System in Humans, Here’s How to Keep It Healthy!
The nose is the first organ of the respiratory system. This human breathing apparatus is the entrance for outside air into the respiratory system. There are fine hairs or cilia inside the human nose.
These fine hairs are part of the air purification system, protecting the nasal passages and other parts of the respiratory tract and filtering dust and other particles from the inhaled air that enter the nose.
Apart from through the nose, sometimes people can also breathe in and out through the mouth. This breathing mechanism is mainly carried out in people who are used to breathing through the mouth.
Sinuses are air spaces located behind the front of the skull, along the sides of the nose and along the forehead. The sinuses of the human respiratory system help regulate air temperature when breathing.
Organ Systems of the Human Body and Their Images and Functions
Sinuses regulate the temperature and humidity of the air you breathe, relieve tension in the bones of the skull, and play a role in timbre and voice.
Also called adenoids or goiters are lymphoid tissue or lymph nodes located at the top of the throat. If the adenoids swell and start to interfere with breathing, the doctor may remove them.
The lymphatic system consists of cellular nodes and connecting blood vessels that carry body fluids throughout the body. This system helps the body fight infection by filtering foreign substances, including bacteria, and producing cells (lymphocytes) to fight germs.
The tonsils can help prevent infection. However, this part is actually classified as an unimportant part of the human respiratory system. So, if your tonsils are infected, the doctor will remove them surgically.

The pharynx or throat is located behind the nose and mouth. The pharynx is the part of the digestive and respiratory systems that transports food and air.
At the bottom of the pharynx, the passage divides into two: one for food and one for air. The esophagus is the part where food enters and leads to the stomach and intestines. while breathing through the throat.
The respiratory system pharynx directs inhaled air from the nose or mouth into the larynx and trachea.
Part of the pharynx, called the nasopharynx, contains the epiglottis. It seals off the passage to the esophagus, preventing air from entering the digestive system.
Recognize the Anatomy of the Human Body and Its Forming Organs
The epiglottis is a cartilage covering that covers the airways during swallowing and prevents food and liquid from entering the lungs.
When you inhale, the epiglottis opens and the inhaled air enters the lungs through the larynx. However, the epiglottis closes when food is eaten.
The lower respiratory tract contains the larynx, trachea, ribs, lungs, pleura, bronchioles, alveoli, bronchial tubes, and diaphragm.
The larynx is also part of the respiratory system. The larynx is a hollow tube that allows air to flow from the trachea (pharynx) down the trachea and into the lungs.
Note]Upsr Science: The Process of Human Life
, the larynx is a 2-inch tube made up of nine cartilaginous sections. This tube connects the pharynx and trachea and is held together by ligaments, membranes, and fibrous tissue.
The larynx also contains the vocal cords which help people make sounds. This is why the larynx is often called the vocal cords.
The trachea or trachea is the continuous part of the airway below the larynx. The trachea allows air to flow directly into the lungs. This tube is very rigid and consists of several tracheal rings.
The trachea is also lined with cilia which sweep fluid and debris out of the airways and keep them from entering the lungs.

When the tracheal tubes narrow due to inflammation or obstruction, this condition limits the flow of oxygen to the lungs.
The ribs of the human respiratory system support and protect the thoracic organs from shock and shock, including the heart and lungs.
The lungs are in the chest. This human respiratory organ is protected by ribs and covered by a membrane called the pleura.
In the human respiratory system, the lungs also distribute inhaled oxygen into the blood. The oxygen-carrying blood flow is then distributed to all organs and other tissues so that the body’s organs function properly.
The Human Respiratory System: Definition, Functions, Organs, And Disorders Of The Respiratory System
Everyone’s lungs have hundreds of millions of alveoli. This network of alveoli, bronchioles, and bronchi is known as the bronchial tree.
Alveoli, or alveoli, are very small air sacs in the lungs. This section is at the end of the bronchial tube.
In the respiratory mechanism, the alveoli function as a place for exchanging oxygen and carbon dioxide in the air you breathe.
When you inhale, air enters the trachea through the nose or mouth. From there, air enters the lungs through the bronchi or tubes.

This tube allows air to flow in and out of the lungs, allowing you to breathe. Bronchial tubes are sometimes called bronchi or airways.
The diaphragm is the muscular wall that separates the chest and abdominal cavities. In belly breathing, the diaphragm moves downward, drawing in air and expanding the lungs.
Inside the nasal cavity there are thick short hairs that function to filter air and dust that enters the nose.
It can be said that the alveoli are in an important position. This is because the lungs are a place for exchanging oxygen or O2 and carbon dioxide or CO2.
Brainly Explain What Is An Organ System
The process of human breathing begins when air enters the body and flows through the nose into the trachea.
The windpipe is located behind the nose and mouth. As it enters the nose, air enters the lungs.
The air in the lungs is absorbed as oxygen in the small blood vessels. It is distributed throughout the body in the blood.
Air in the form of carbon monoxide (CO2) from the blood is separated from the body and discarded. This treatment is done by breathing.

The lungs are the organs responsible for regulating air intake and separating oxygen and carbon dioxide. Like the kidney, it has two lungs, the left and the right lung.
The Human Respiratory System: Definition, Processes, Organs And Their Parts
Previously it was mentioned that human lungs have two lungs, namely the right lung and the left lung. These lungs appear to be of different sizes. According to the description of
, the weight of the left lung in adults is approximately 325 – 550 g. While the right lung weighs around 375 – 600 g.
The lungs are divided into an area called the mediastinum. This area includes the heart, trachea, esophagus, and lymph nodes. The lungs are covered by a protective membrane known as the pleura and are separated from the abdominal cavity by the diaphragm muscle.
Pleura is a thin double membrane that covers the lungs. This lining secretes a fluid called serous fluid. Its function is to lubricate the lung cavity so it doesn’t irritate the lungs when they expand and contract when breathing.
The diaphragm is the muscle that separates the abdominal and thoracic cavities, get to know their function
The bronchi are branches of the trachea that lie behind the trachea (trachea) in front of the lungs. The bronchi are the airways that allow air to flow properly from the trachea to the alveoli.
The function of this section is to prevent infection. This is because the bronchi are surrounded by various types of cells, including hair cells and mucous cells. These cells can later trap disease-carrying bacteria so they don’t enter the lungs.
The main bronchi divide or branch into smaller bronchi with small glands and cartilage in their walls. These smaller bronchi divide into smaller tubes. These tubes are called bronchioles.
Thus, bronchioles are small branches without glands or cartilage. Its function is to transport air from the bronchi to the alveoli. Another function of this section is to regulate the air that enters and leaves when you breathe.
Important Functions Of The Bronchus And Bronchioles In The Respiratory System
Lung function is also supported by the presence of alveolar organs. This section is a sac at the end of the bronchioles. Alveoli, or alveoli, are useful for the exchange of oxygen and carbon dioxide.
These organs then absorb the oxidants from the air and carry them away from the bronchi where they flow into the air. Meanwhile, carbon dioxide flows from the blood into the alveoli and is exhaled.
The function of the lungs is to support the respiratory system. This organ works as a complex mechanism, but the process is so fast that we don’t even notice it.
, the process of breathing begins when air enters through the nose or mouth. Once inside, air flows down the windpipe and enters the trachea. From the trachea, air moves to the left and right bronchi.
Respiratory Equipment In Humans And Their Functions Worksheet
Air then enters the bronchioles and enters the alveoli. The interior of the alveoli is covered with a network of tiny blood vessels, or capillaries. At this stage, the exchange of oxygen and carbon dioxide occurs.
The process of exchange is called respiration or exhalation. As an excretory organ, the function of the lungs is to remove waste products in the form of carbon.
