“Air We Go!”
(Basics of Respiration)
(Basics of Respiration)
This type of respiration happens in the lungs and involves taking in O₂ and releasing CO₂.
What is pulmonary breathing?
These openings warm and filter the air and house the olfactory organ.
What are the nostrils?
These two spongy organs contain bronchi, bronchioles, and alveoli.
What are the lungs?
The process of air entering and leaving the lungs is called this.
What is pulmonary ventilation?
This common respiratory infection causes coughing, mucus, and is worsened by smoking.
What is bronchitis?
This type of respiration occurs in the mitochondria and releases energy for the cell.
What is cellular respiration?
This shared cavity connects the respiratory and digestive systems and contains the epiglottis.
What is the pharynx?
This double-layer membrane surrounds the lungs and contains fluid to ease movement.
What is the pleura?
During inspiration, these muscles contract to move the ribs outward.
What are the intercostal muscles?
This condition causes temporary narrowing of bronchi and bronchioles and is often triggered by allergies.
What is asthma?
Cellular respiration uses this gas to produce energy.
What is oxygen?
This structure contains the vocal cords and sits between the pharynx and trachea.
What is the larynx?
These muscles, along with the diaphragm, help change lung volume during breathing.
What are the intercostal muscles?
Gas exchange occurs in this specific part of the respiratory system.
What are the pulmonary alveoli?
This serious disease is caused by Koch’s bacillus and can destroy lung tissue.
What is tuberculosis?
This waste gas produced by cells is transported back to the lungs for removal.
What is carbon dioxide?
This tube is reinforced with C-shaped rings and lined with ciliated cells that trap impurities.
What is the trachea?
These bones, along with the sternum and spine, form the protective rib cage.
What are the ribs?
Gas exchange happens by this natural process, where molecules move from high to low concentration.
What is diffusion?
These infections include symptoms like fever, sneezing, coughing, and are caused by viruses or bacteria.
What are colds, flu, or COVID?
These tube-like structures carry O₂ from the lungs to cells and return CO₂ back to the lungs.
What are blood vessels (capillaries)?
These tiny sacs at the end of bronchioles are the site of gas exchange and appear in clusters.
What are alveoli?
What are alveoli?
This dome-shaped muscle contracts downward during inspiration.
What is the diaphragm?
When relaxed breathing occurs at 6 breaths per minute, the body is in this state.
What is rest (relaxation)?
This prevention measure helps avoid environments where Koch’s bacillus thrives.
What is staying in clean, dry, well-ventilated areas?
