18 kwi 2023 · Inside the lungs, the airways keep branching into narrower airways until the air sacs are reached. A person’s physical fitness greatly depends on how well their lungs and heart work. Your lung function can be measured using various breathing tests.
29 wrz 2023 · Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system’s main job is to transport oxygen and remove extra carbon dioxide.
7 cze 2024 · As carbon dioxide exits the body, oxygen needed for cellular respiration enters the body through the lungs. ATP, produced by cellular respiration, provides the energy for the body to perform many functions, including nerve conduction and muscle contraction.
The main function of the lungs is to perform the exchange of oxygen and carbon dioxide with air from the atmosphere. To this end, the lungs exchange respiratory gases across a very large epithelial surface area—about 70 square meters—that is highly permeable to gases.
