Dýchají

Dýchají is a Czech word that translates to "they breathe" in English. It refers to the biological process by which living organisms take in oxygen and expel carbon dioxide. This vital function is essential for cellular respiration, the process that provides energy for life.

In humans and most animals, breathing occurs through lungs. Air is inhaled through the nose or mouth, travels down the trachea (windpipe), and into the lungs, where oxygen is absorbed into the bloodstream and carbon dioxide is released to be exhaled. The diaphragm, a large muscle below the lungs, plays a crucial role in this mechanical process by contracting and relaxing to draw air in and push it out.

Plants also respire, though their gas exchange is different. They take in carbon dioxide from the atmosphere through small pores called stomata, primarily on their leaves, and release oxygen as a byproduct of photosynthesis. While plants don't have lungs, they do have a continuous process of gas exchange at the cellular level.

The term "dýchají" can be used in various contexts, from describing the simple act of breathing by an animal to more figurative uses, such as when discussing the life force or vitality of something. For instance, one might say a forest "dýchají" to imply its vibrant and living nature.
