Sisäänhengittäminen
Sisäänhengittäminen, in Finnish, refers to the act of inhaling or breathing in. It is a fundamental biological process that is essential for life. During inhalation, the diaphragm and intercostal muscles contract, increasing the volume of the thoracic cavity. This volume increase leads to a decrease in pressure within the lungs, causing air to flow from the higher pressure outside the body into the lungs.
The inhaled air, which is rich in oxygen, travels through the trachea, bronchi, and into the alveoli,
The rate and depth of inhalation are regulated by the respiratory center in the brainstem, which responds
Inhalation is the first half of the respiratory cycle, preceding exhalation. Together, these two processes ensure
