Respiratory System
Fichas del conjunto (24)
- 1What is Aerobic Respiration?Respiration using oxygen, which releases energy and produces carbon dioxide and water.
- 2What is the word and balanced symbol equation for Aerobic Respiration?
- 3What is the word and balanced symbol equation for Anaerobic Respiration?
- 4Why can't a fish breathe in air?Because it is not dense enough to push between the gill filaments.
- 5What is the Human Thorax?The chest cavity
- 6The trachea...is a flexible tube, surrounded by rings of cartilage to stop it collapsing.
- 7The bronchi...branches off the trachea.
- 8The bronchioles...branch off a bronchus
- 9The lungs...inhale and exhale air for gas exchange.
- 10the alveoli (air sacs)...is the site of gas exchange.
- 11The intercostal muscles...raise and lower the ribs.
- 12The pleural membranes...protect and lubricate the surface of the lung.
- 13The diaphragm...is a muscular 'sheet' between the thorax and the lung.
- 14Where does oxygen enter and leave?It enters the blood in the lungs and leaves the blood in body tissues.
- 15Where does carbon dioxide enter and leave?It enters the blood in the body tissues and leaves via the lungs.
- 16What happens when the intercoastal muscles contract?The rib cage moves upwards and outwards. The Diaphragm contracts and flattens. Increases the volume of the chest cavity - INSPIRATION!
- 17What happens when the intercoastal muscles relax?The rib cage moves downwards and inwards. The diaphragm also relaxes and moves upwards. This decreases the volume of the chest cavity-EXPIRATION!
- 18What is Tidal Air?The volume of air being breathed in or out in a normal breath.
- 19What is Vital Capacity?It is the maximum volume of air that can be used for gas exchange in the lungs - a maximum breath in followed by a maximum breath out.
- 20What is Residual Air?It is the volume of air that stays in the lungs when we breathe out.
- 21Have have the alveoli adapted for gas exchange?They have a massive surface area, a moist, thin, permeable surface and an excellent blood supply.
- 22The trachea and bronchi defend the respiratory system against disease by...produce mucus to trap dust and microorganisms and are lined with millions of cilia which move the mucus from the lungs into the throat, where it's swallowed.
- 23Name 3 types of respiratory diseasesAsbestosis, Asthma, Bronchitis, Cystic Fibrosis, Lung Cancer, Pneumonia.
- 24What happens during an asthma attack?The lining of the bronchioles becomes inflamed, fluid and mucus builds up in the airways and the muscles contract, constricting airways.
