Fichas del conjunto (20)
- 1What is respiration?A series of chemical changes that take place in cells to release energy.
- 2What is word equation for respiration?Oxygen+Glucose
---> Carbon Dioxide+Water+Energy - 3What is the system that takes air into your body and ultimately makes oxygen available to the cells?The respiratory system
- 4Tell of the structure of the respiratory system:1. nasal cavity
2. epiglottis
3. pharynx
4. larynx
5. trachea (windpipe)
6. lungs:
a) bronchus
b) bronchioles
c) alveoli
7. intercostal muscle
8. ribs
9. diaphragm - 5What is your nasal cavity?The nasal cavity (nasal fossa, or nasal passage) is a large air filled space above and behind the nose in the middle of the face. Each cavity is the continuation of one of the two nostrils.
- 6What are cilia?Tiny hairs in your nasal cavity that trap pollen, dust and bacteria using mucus. They also push mucus from your nose to your pharynx by constantly waving (back and forth).
- 7What does the nasal cavity do?It warms and moistens the air that enters it.
- 8What is the pharynx?A membrane-lined cavity that connects the mouth and nasal cavity to the oesophagus.
- 9What is a alternate name for the larynx?voice box
- 10What is the trachea?the windpipe is garden-hose thick tube with thin walls that stops itself from collapsing with cartilage-based rings.
- 11What are the two tubes that trachea divides into called?Bronchi
- 12True or False: The bronchi divide into smaller tubes called bronchioles.True
- 13What are alveoli?Tiny air sacs that allow for rapid gas exchange.
- 14Describe gas exchange:Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
- 15What is breathing?Breathing (or respiration, or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
- 16What happens to your ribs and diaphragm (thin layer of muscle) when you breath in (inhale)?The rib cage is pulled up and out and the diaphragm contracts and flatten.
- 17True or False: When you exhale, your diaphragm twists and your ribs move sideways.False
- 18How does your body react to your sudden need for oxygen when exercise?Breathing deeper and faster and having you heart beat quicker.
- 19Where does your body's energy come from?Food and oxygen.
- 20How many times do you breath in and out daily?20,000 times
