For cells to produce energy through a process called cellular respiration, oxygen must be supplied. The following 7 methods explain how cells get oxygen:
- Artificial Ventilation: When someone is unable to breathe properly for themselves, artificial ventilation techniques such as mechanical ventilation or the use of ventilators can be used to get oxygen into their lungs.
- Lung Respiration: The respiratory system is how both humans and many other animals breathe in oxygen. After being breathed into the lungs, oxygen diffuses into the blood and travels to the cells.
- Cells use a process called aerobic cellular respiration, which occurs in the mitochondria and oxidizes glucose with oxygen to produce water, carbon dioxide, and energy. The majority of eukaryotic cells exhibit this.
- Photosynthesis in Plants: Photosynthesis is the process by which plants, algae, and certain microbes change carbon dioxide and sunlight into glucose and oxygen. The air is filled with the expelled oxygen.
- Oxygen treatment: In medical settings, oxygen treatment is used to give patients who require more oxygen or who have respiratory problems higher concentrations of oxygen.
- Diffusion in Single-Celled creatures: Amoebas and bacteria are examples of single-celled creatures that may absorb oxygen by means of simple diffusion across their cell membranes.
- Hemolymph (Insects): Hemolymph is a fluid that insects and other arthropods utilize in place of blood to transport oxygen. Tracheal tubes allow oxygen to enter hemolymph directly.
These many methods guarantee the delivery of oxygen to cells in diverse animals and environmental settings. The particular technique is determined by the habitat, respiratory system, and anatomy of the organism.
