Answer: The Respiratory membrane: The wall of the alveoli are composed primarily of a single layer of squamous epithelial cells, called type I cells, surrounded by a flimsy basement membrane. See page 815 anatomy and physiology 8th
Answer: The membrane of the alveolus, the air sacs in the lungs where this process takes place, is only one cell thick. The wall of the capillary running adjacent to the alveolus is also one cell thick, so the gases are exchanged between the alveolus and the capillary cell membranes.
Answer: Lungs The lungs are the main organs of the respiratory system. In the lungs oxygen is taken into the body and carbon dioxide is breathed out. The red blood cells are responsible for picking up the oxygen in the lungs and carrying the oxygen to all the body cells that need it. The red blood cells drop off the oxygen to the body cells, then pick up the carbon dioxide which is a waste gas product produced by our cells. The red blood cells transport the carbon dioxide back to the lungs and we breathe it out when we exhale.
Trachea The trachea is sometimes called the windpipe. The trachea filters the air we breathe and branches into the bronchi.
Bronchi The bronchi are two air tubes that branch off of the trachea and carry air directly into the lungs.
Diaphragm Breathing starts with a dome-shaped muscle at the bottom of the lungs called the diaphragm. When you breathe in, the diaphragm contracts. When it contracts it flattens out and pulls downward. This movement enlarges the space that the lungs are in. This larger space pulls air into the lungs. When you breathe out, the diaphragm expands reducing the amount of space for the lungs and forcing air out. The diaphragm is the main muscle used in breathing.
Answer: Human respiratory system contain wind pipe or trachea, bronchus, bronchi, alveoli with blood capillaries. Lungs have air sacs or alveoli which are surrounded by capillaries which oxygenate, de-oxygenated blood.
Answer: Some of the components of the respiratory system are the majorstructures like the throat, windpipe, and lungs. The other partsare smaller things like the alveoli, which are tiny sacs in thelungs where over a million of them work to transfer oxygen andcarbon dioxide in and out of blood.
Answer: The respiratory membrane is formed by a combination of the walls ofalveoli and walls of capillaries. It consists of type 1 alveolarcells, a basement membrane, capillary endothelium, alveolarepithelium and macrophages.
