How does it work? Respiratory system in humans

The respiratory system in humans has a heavy task every day. Humans breathe 12 to 20 times a minute, which continues without stopping.

Don't think that the organs of the human respiratory system only function by breathing. These organs also play a role in human ability to speak and work as worshipers.

How the respiratory system works

In the respiratory system in humans, there are organs in the form of airways, lungs, lungs and respiratory muscles. These organs have a mission to assist the body in gas exchange. There are also two gas exchanges, namely between air and blood and between blood and cells throughout the body. In essence, these organs help channel air to all parts of the body.

There are also organs called alveoli and alveolar ducts. Cells have the shape of grape dots attached to one another. With alveolar canals, cells are responsible for the exchange of gases in the body.

In addition to its role in the exchange of air and gas, the function of respiratory organs filters, moisturizes and warms the air that enters the body. In addition, the respiratory system also plays a role in maintaining and balancing conditions in the body to remain stable. In medical terms, the ability to balance this condition is called homeostasis.

Respiratory system organs in humans

In the respiratory system in humans, it is divided into two, namely the upper and lower respiratory systems. For more details, you can read the explanation below.

The upper respiratory system is located outside the thoracic cavity and includes:

Nose

Inside the nasal cavity is a sticky mucous membrane that lines the nasal cavity. The function of this mucous membrane is to trap dust or dirt particles that enter the nose. In this cavity, there are also fine hairs called eyelashes. The aim is to prevent and eliminate dust or dirt particles that penetrate through the nose. The trick is to sneeze.

sine

Namely, a room or cavity that contains air and is in the skull, around the face, behind the cheekbones, nose and forehead. This cavity is related to the nose.

larynx

A dual role, which is breathing and helping to speak.

pharynx

During this process, this organ passes food and drink into the next digestive tract. Besides the pharynx also plays a role in the ability to speak.

Lower respiratory tract, consisting of:

Trachea

Is the main respiratory tract to the lungs. This organ is located under the larynx.

bronchiole

Is an organ that branches from the trachea to the lungs. The function of the bronchi is to take air to be sent to the lungs.

Lungs

It is the largest organ and plays an important role in the respiratory system, which plays a role in maintaining air and providing oxygen for all body activities that are channeled through blood vessels and which exhales the body's carbon dioxide gas.

spiral

Is the main respiratory muscle. This organ can contract and relax alternately, so that air can enter the lungs.

The process of breathing in humans

When you breathe, the respiratory organs move together. The diaphragm contracts so that the lungs have more room to fill the air. For the purpose of filling the air in the lungs, the rib muscles are also lifted.

Air enters through the nose and mouth, then passes through the trachea or throat. At this point, the eyelashes vibrate so that mucus and dirt can come out of the lungs. In addition, through the bronchi and bronchioles, air passes through the branches of the lungs. When you exhale, most organs work in opposite directions.

The respiratory system in humans looks simple, but it contains important organs. In one breath, these organs must carry out a series of complex processes and work together to get oxygen for the survival of all body systems. Therefore, if you have a disease that causes interference with the respiratory system, consult your doctor immediately before there is interference with other systems and organs.
