Hengitysprosessit refers to the biological processes involved in respiration, the fundamental mechanism by which living organisms obtain energy and release waste products. In multicellular organisms, this primarily involves the exchange of gases, namely oxygen and carbon dioxide, between the organism and its environment. For animals, this typically means inhaling oxygen and exhaling carbon dioxide. This gas exchange occurs within specialized respiratory organs, such as lungs in mammals and birds, gills in fish, or through the skin in some amphibians.
The process of respiration can be broadly divided into external and internal respiration. External respiration, also
In plants, while gas exchange occurs through pores called stomata on their leaves, the term "hengitysprosessi"
