Respiratory organs

The respiratory system is a collection of organs and tissue that assist in breathing. Your airway, lungs, and blood arteries are all part of it. The respiratory system includes the muscles that power your lungs. These components work together to transport oxygen throughout the body while also removing waste gases such as carbon dioxide.

The following are the components:

1. Nose

2. Mouth

3. The Throat (pharynx)

4. Box for speaking (larynx)

5. Bronchial tube (trachea)

6. A large number of airways (bronchi)

7. Airways that are too small (bronchiole)

8. Lung.

Respiratory organs

All of the organs involved in breathing make up the respiratory system. The nose, pharynx, larynx, trachea, bronchi, and lung are among them.

The trachea and both lungs, as well as their lobes and airway, are shown in this illustration of the respiratory system. The lymph node and diaphragm are also depicted. Oxygen is inhaled into the lungs, where it travels through the alveoli’s thin membranes and into the bloodstream.

Gills, integumentary exchange regions, and lungs are the three basic types of respiratory structures found in vertebrates.

Respiratory structures usually have an attenuated shape and a large semi permeable surface in comparison to the structure’s volume. There is usually a circulation of body fluids within them (blood through the lungs, for example). There are two types of pumping processes that are commonly encountered: one to replenish the external oxygen-containing medium, and the other to ensure that body fluids circulate through the respiratory structure.

Types of respiratory organs

1. Direct Diffusion 

2. Skin and Gills

3. Tracheal System

Direct Diffusion 

Diffusion via the outer membrane is adequate to supply the oxygen needs of tiny multicellular organisms. For organisms with a diameter of less than 1 mm, direct diffusion across surface membranes is an efficient method of gas exchange. Every cell in the body of basic creatures like cnidarian and flatworm is near to the external environment. Their cells are kept moist, and gases are readily diffused through direct diffusion.

Skin and Gills

Earthworms and amphibians breathe through their skin (integument). Just beneath the epidermis, a thick network of capillaries promotes gas exchange between the external environment and the circulatory system. To allow gases to dissolve and diffuse across cell membranes, the respiratory surface must be kept wet.

Water-dwelling organisms require oxygen from the environment. Although oxygen dissolves in water, its concentration is lower than in the atmosphere. The oxygen content of the atmosphere is approximately 21%. The oxygen concentration in water is significantly lower. Gills have evolved in fish and many other aquatic species to help them absorb dissolved oxygen from the water. Gills are highly branching and folded thin tissue filament. The dissolved oxygen in water rapidly diffuses through the gills and into the bloodstream as water passes over them.

Tracheal Systems

Because an insect’s respiratory system is separate from its circulatory system, blood does not play a direct role in oxygen transfer. The tracheal system, which consists of a network of small tubes that transport oxygen throughout the body, is a highly technical type of respiratory system found in insects. In active animals, the tracheal system is the most direct and efficient breathing system. Chitin is a polymeric substance that makes up the tube in the tracheal system.

The thorax and abdomen of insects include holes called spiracles. These apertures connect to the tubular network, allowing oxygen to enter the body while also regulating CO2 and water evaporated diffusion. The spiracle allows air to enter and exit the tracheal system. Some insects can shift their bodies to ventilate the tracheal system.

Main organs of respiratory system 

The respiratory system absorbs oxygen from the air we breathe and exhales the carbon dioxide we don’t desire. The lungs are the most important organ in the respiratory system. The nose, trachea, and breathing muscles are among the other respiratory organs (the diaphragm and the intercostal muscles).

Lungs

The process of gas exchange known as respiration is the primary function of the lungs (or breathing). During breathing, oxygen from the outside air enters the bloodstream, while carbon dioxide, a waste byproduct from metabolism, exits the bloodstream.

Nose

Your respiratory system includes your nose. It lets air into your body, then filters debris before warming and moistening the air. Your nose is responsible for your sense of smell as well as helping to shape your look. A stuffy nose and nosebleed are two frequent symptoms that affect your nose.

Trachea

The primary purpose of your trachea is to transport air into and out of your lungs. It provides a reliable channel for oxygen to enter your body because it is a rigid, flexible tube.

Conclusion

The respiratory system is made up of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are part of the respiratory system. These parts work together to deliver oxygen throughout the body and remove waste gases like carbon dioxide.

The respiratory system is made up of all of the organs involved in breathing. They include the nose, pharynx, larynx, trachea, bronchi, and lungs.

In this picture of the respiratory system, the trachea and both lungs, as well as their lobes and airways, are depicted. Lymph nodes and the diaphragm are also shown. Oxygen is inhaled into the lungs, passing through the thin membranes of the alveoli and into the bloodstream.

The three fundamental types of respiratory structures found in vertebrates are gills, integumentary exchange areas, and lungs.
