Question | Answer |
Boyle's Law | When gas is kept as a constant temperature, pressure and volume are inversely proportional and have a constant product. |
What type of pressure is associated with Boyle's law? | Atmospheric pressure, intrapulmunoic pressure & intrathoracic pressure |
Respiratory tract icludes | trachea, pharynx, larynx, oral cavity, nasal cavity and organs of respiration (lungs) |
External respiration | gas exchange between luns and blood |
Internal respiration | gas exchange between blood and cells. |
Organs of articulation & resonance | oral, nasal & pharangeal cavities |
Trachea | connects larynx with bronchi |
What is the trachea composed of? | 16-20 horseshoe shaped cartilage rings its shape can be altered by the tracheal muscle inferior end connects to the bronchi |

Left bronchus | 2 secondary bronchi 8 tertiary bronch1 |
Division of tertiary bronchi | bronchioles->terminal bronchioles->alveolar ducts->air sacs |
alveolar ducts and air sacs | covered in tiny pits |
Alveoli | pits found in walls of terminal bronchioles -covered with capillaries which exchange oxygen with carbon dioxide -at this level become less cartilaganous and more muscular |
Pleurae | sac like structure that encases each lung |
Parietal pleura | lined each pleurae |
Visceral pleura | 2nd layer and is contionous with the parietal pleura |
How many lobes does the right lung have? | 3 lobes- superior, middle & inferior |
Negative pressure | the vaccum cause by the parietal and visceral pleura |
Respiration | breathing for air |
Primary function of breathing | oxygenation of blood |
Secondary function of breathing | air from lungs used as a power source for speech (speech breathing) |
2 subprocesses during breathing | inhalation or inspiration |
Inhalation | active process in which muscles are involved |
Exhalation | passive process, muscles relax |
3 passive processes in Exhalation | gravity, unbending of bones/cartilages and elasticity of lung tissue |
Exhalation (speech breathing) | active process because we have to control the passive process when speaking |
During the process of inhalation | enlarge the thoracic cavity |
Superior border of the thoracic cavity | shoulder or pectoral girdle |
Inferior border of the thoracic cavity | Diaphragm which separates the thoracic cavity from the abdominal cavity |
Shoulder (pectoral) girdle made up of | shoulder and scapula |
Anterior border of thoracic cavity | sternum |
Posterior border of the thoracic cavity | vertebral column |
Lateral border of thoracic cavity | ribs and costal cartilages |
Adult vertebral column | 7 cervical, 12 thoracic, 5 lumbar, a sacrum, 1 coccyx |
Adolescent vertebral column | 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, 4 coccyx |
Vertebral foramen | an arch that encloses a space for the spinal cord |
Spinous process | prominent projection, directed dorsally and more inferiorly from the neural arch |
Transverse process | projects laterally from the vertebrae. |
Articular facets | located on thoracic vertebrae provide attachments for ribs |
Ribs 1-7 | true ribs directly attach to sternum by costal cartilages |
Ribs 8-10 | false ribs that attach directly to one long costal cartilage |
Ribs 11-12 | floating ribs, has no anterior attachments |
Ribs attach posteriorly | by cosco cental ligament and cosco transverse ligaments |
At respiratory rest | intrapulmonic pressure is equal to atmospheric pressure. At the same time intrathoracic pressure is less than both. |
thoracic muscles used in inhalation | diaphram, external intercostal, pectoralis major, pectoralis minor, serratus posterior superior, subclavius & levator costalis |
neck muscles used in inhalation | sternocleoidomastoid, scalenus anterior, scalenus medial, scalenus posterior |
back muscles used in inhalation | sacrospinalis & latissmus dorsi |
thoracic muscles used in exhalation | internal intercostal muscles, serratas posterior inferior, transverse thoracic muscles, subcostals |
back muscles used in exhalation | iliocostalis dorsi, iliocostalis lumborum, quadratus lumborum |
abdominal muscles involved in exhalation | rectus abdominus, transverse abdominus, external obliques, internal obliques |
Origin | fixed point of attachment |
Insertion | moveable point of attachment |
Course | direction of fibers |
Innervation | nerve supply |
Function | the physiological accomplishments |
Diaphragm | single muscle that separates thoracic cavity from the abdominal cavity |
Origin of the diaphragm | posterior surface of the xiphoid process, inner surface of the upper lumbar vertebrate ans well as the inner surface of ribs 7-12 |
Insertion of the diaphragm | central tendon |
Innervation of the diaphragm | phrenic nerve |
Function of the diaphragm | to enlarge the thoracic cavity in its vertical dimension during unforced inhalation |
External intercostal muscles | 11 pairs located in between ribs |
Origin of the external intercostal muscle | inferior surface of rib |
Insertion of external intercostal muscle | superior surface of the rib |
Course of the external intercostal muscle | downward and medially toward the sternum. Downward and laterally away from the vertebral column |
Innervation of the external intercostal muscles | intercostal nerves |
Function of the external intercostal muscles | raise the ribs and increase their size of the thoracic cavity during unforced inhalation |
Origin of internal intercostal muscles | inferior surface of the rib above |
Insertion of internal intercostal muscle | medical surface of the rib immediately below |
Course of internal intercostal muscles | downward and laterally away from the sternum. Downward and medially toward the vertebral column |
Innervation of the internal intercostal muscles | intercostal nerves |
Function of internal intercostal muscles | help lower the ribs during unforced exhalation |
Origin of levator costalis | 7th cervical & upper 11 thoracic vertebrate on the transverse process |
Insertion of the levator costalis | lateral surface of the rib immediately below, course downward and laterally |
Innervation of the levator costalis | intercostal nerves |
Function of the levator costalis | help raise the shoulder girdle and enlarge the thoracic cavity during forced inhalation |
Origin of sternocleoidomastoid | anterior and the superior surface of the manubrium, they insert into the clavicle and scapula by means of a tendon |
Insertion of sternocleoidomastoid | course upward and posteriorally. Also attach to the mastoid process of the temporal bone. |
