Insects get oxygen from the air to fuel muscles and tissues. Those insects that move a lot, particularly through flight, need more oxygen than sedentary insects. Eventually, insects release carbon dioxide as waste back into the air.
How are we different? Humans have a combined respiratory and circulatory system, where oxygen is moved in the blood to muscles and tissues within a closed system.
For insects, respiration is separate from the circulatory system. Oxygen and carbon dioxide gases are exchanged through a network of tubes called tracheae. Instead of nostrils, insects breathe through openings in the thorax and abdomen called spiracles.
Insects that are diapausing or non-mobile have low metabolic rates and need to take in less oxygen. Insects exchange oxygen and carbon dioxide through spiracles noted by circle. Photo by Whitney Cranshaw, www.
One of the processes are known as the citric acid cycle. So instead of speaking about insects, which you came for, I will continue with another topic. Humans breathe through their lungs, transporting oxygen in and carbondioxide out from alveoli a hollow cavity where the gas exchange occurs through diffusion between the alveoli and the blood. Can you imagine that humans take a breath 16 times per minute? Interestingly enough, insects breathe through their bones, to put it simply.
What it actually means is that air is transported into the body through small pores in the skin or skeleton. The pores are known as spiracles. It is similar to human bronchus, creating a beautiful network or as I like to refer to it: biological art wow so deep. The air is usually transported through the process of diffusion, which means the breathing is not mechanical.
The breathing is therefore highly dependent on the concentration of oxygen in the air. The less oxygen, the harder it is for the oxygen to reach the deepest tracheae. As cool as it may sound to breathe through your skeleton, having lungs is way better. Imagine a grasshopper the size of a bear. Hell no! Hanna Tomic.
