Insect respiratory system
–
Bobo.id – Did you know, one of the characteristics of living things is breathing or respiration.
Likewise with various types of animals on Earth.
Unlike humans, who naturally breathe with lungs, animals have a variety of different respiratory organs.
For example, fish breathe with gills, mammals usually breathe with lungs, then there are also insects that breathe with trachea.
Well, this time Bobo wants to explain about insect respiratory system. Starting from the respiratory organs, functions, and also their location.
Come on, watch!
Insect respiratory system actually has the same function as other respiratory systems.
Its function is to perform gas exchange.
To be able to breathe insects need a system consisting of several support organs.
In general there are 4 respiratory organs in insects. Anything? Check out the following explanation, yes.

1. Spirakel
Spirakel is part of the external skeleton (exoskeletons). There are pairs in the chest and segments in the abdomen (abdominal cavity) of insects. However, not all segments of the insect have spiracles.
This section can open and close because it is regulated by muscle valves. Its function is as a hole for the flow of oxygen and carbon dioxide into and out.
The valve opens to introduce oxygen and release carbon dioxide. Spiracles can be equipped with fine hair that functions to filter air.
2. Trachea
The trachea is a tube-like tube connected to the spiracles. The structure is solid because it is composed of chitin.
This channel branches through various parts of the insect’s body. The trachea functions as a channel through which oxygen-rich gases flow from outside to the rest of the body.
In addition, the trachea also serves as a channel for circulating carbon dioxide out of the body.
The trachea is affected by taenidia, which are thin in structure. This structure helps the trachea to flex and stretch in the contraction-relaxation process during breathing.

3. Trakeolus
Tracheolus is a branch of the trachea that has a thin structure. Its function is almost the same as the blood capillaries found in vertebrates.
The structure is smooth and contains fluid and is directly connected to the body’s cells so that the spread or exchange of oxygen with carbon dioxide can occur easily. So that the oxygen needs for cells are met.
The tracheoulus is usually not more than 1 micrometer or 0.001 millimeter in diameter. Wow, very small, huh!

4. Air bag
This pouch is shaped like a balloon and is connected to the trachea, a type of breathing apparatus also found in birds.
These pockets can increase respiration to the maximum by providing a large surface area for gas exchange and maintaining air supply.
When the abdomen moves to pump, the air sacs will expand and contract and increase the volume of air to be moved during respiration.
This is very important for most active or large insects as it helps them breathe during movement while flying.
