| # | Front | Back | Hint |
|---|---|---|---|
| 1 | What is the primary function of the respiratory system? | The primary function of the respiratory system is to facilitate gas exchange, bringing oxygen into the blood and removing carbon dioxide from the blood. | Think of respiration as the body's breathing process for oxygen intake and CO2 removal. |
| 2 | Name the two main parts of the respiratory system. | The upper respiratory tract and the lower respiratory tract. | Upper includes nose and pharynx; lower includes larynx, trachea, bronchi, and lungs. |
| 3 | What are the four main components of the upper respiratory tract? | Nasal cavity, paranasal sinuses, pharynx, and larynx. | Think of the upper tract as the airway above the vocal cords. |
| 4 | Which structure is responsible for voice production? | The larynx, also known as the voice box, contains the vocal cords that produce sound. | Larynx = 'larynx' sounds like 'laryngeal' voice production. |
| 5 | What cartilage forms the Adam's apple? | The thyroid cartilage. | Thyroid cartilage is large and shield-shaped, prominent in males. |
| 6 | What is the main conducting airway in the lower respiratory tract? | The trachea. | Think of the trachea as the windpipe that conducts air to the bronchi. |
| 7 | Describe the bronchial tree structure in the lungs. | The trachea divides into primary bronchi, which branch into secondary (lobar) bronchi, then tertiary (segmental) bronchi, leading to smaller bronchioles and alveoli. | Branching resembles a tree, hence 'bronchial tree.' |
| 8 | What is the function of alveoli? | Alveoli are tiny air sacs where gas exchange occurs between the air and blood. | Alveoli are like tiny balloons at the end of the bronchioles. |
| 9 | Which muscles are primarily responsible for inspiration during normal breathing? | The diaphragm and external intercostal muscles. | Think of the diaphragm as the main 'engine' of inhalation. |
| 10 | What is the location and function of the diaphragm? | The diaphragm is a dome-shaped muscle at the base of the lungs that contracts during inspiration to increase thoracic volume. | Diaphragm = primary muscle for breathing. |
| 11 | Name the two layers of the pleura that surround the lungs. | Visceral pleura (adheres to lung surface) and parietal pleura (lines the thoracic cavity). | Pleura layers are like a double membrane envelope around the lungs. |
| 12 | What is the mediastinum? | The mediastinum is the central compartment of the thoracic cavity containing the heart, great vessels, trachea, esophagus, and thymus. | Mediastinum = the 'middle space' of the thorax. |
| 13 | Which structure connects the larynx to the primary bronchi? | The trachea. | Think of the trachea as the main airway leading from the larynx to the lungs. |
| 14 | What is the significance of the carina? | The carina is the ridge at the bifurcation of the trachea into the right and left main bronchi; it's highly sensitive and triggers cough reflex. | Carina = 'corner' where the trachea splits. |
| 15 | Which lung is larger and why? | The right lung is larger because the heart is slightly shifted to the left side of the thorax. | Right lung has three lobes; left lung has two. |
| 16 | Name the lobes of the right lung. | Upper (superior), middle, and lower (inferior) lobes. | Right lung = three lobes; think 'R' for 'Right' and 'Three.' |
| 17 | Name the lobes of the left lung. | Upper (superior) and lower (inferior) lobes; the left lung also has the cardiac notch. | Left lung has two lobes, accommodating the heart. |
| 18 | What is the function of the alveolar capillary network? | It facilitates gas exchange between alveolar air and blood in pulmonary capillaries. | Think of alveoli and capillaries as the site of oxygen and CO2 transfer. |
| 19 | Describe the blood supply to the lungs. | Pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs; pulmonary veins return oxygenated blood to the left atrium. | Pulmonary arteries are unique because they carry deoxygenated blood. |
| 20 | What is the role of the bronchopulmonary segments? | They are the functionally independent units of the lung, each served by its own segmental bronchus and blood supply, facilitating surgical resections. | Segments are the 'building blocks' of lung anatomy. |
