May 3, 2024 · Lung, in air-breathing vertebrates, either of the two large organs of respiration located in the chest cavity and responsible for adding oxygen to and removing carbon dioxide from the blood. The lungs are soft, light, spongy, elastic organs that normally, after birth, always contain air.

May 23, 2024 · Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration). It appears as a white microcrystalline granule. Adrenaline is normally produced by the adrenal glands and by a small number of neurons in the medulla oblongata.
May 11, 2024 · Your respiratory system is made up of your lungs, airways, pharynx, larynx, nose and mouth. Its main function is to breathe in oxygen and breathe out carbon dioxide. Learn how the respiratory system works and what happens when you breathe in and out.
3 days ago · A mitochondrion (/ ˌ m aɪ t ə ˈ k ɒ n d r i ə n /; pl.: mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy ...
May 15, 2024 · The regulation of breathing is a vital physiological process managed by the brainstem, which controls the diaphragm and intercostal muscles for inhalation and exhalation. Chemical sensors monitor blood levels of oxygen, carbon dioxide, and pH, triggering adjustments in breathing rate and depth to maintain homeostasis.
May 16, 2024 · What is Aerobic Respiration? Aerobic respiration is the cellular respiration process that occurs in the presence of oxygen. It is the respiratory process where the electron is transferred to dioxygen molecules (O 2), generating water molecules and energy molecule ATP. Here glucose molecule is completely oxidized into energy (ATP), carbon ...
