Respiration-Anatomy
Anatomical Parts of the Respiratory System
| Question | Answer |
|---|---|
| vertebral column | composed of vertebral segments combined to form a strong but flexible column; the structure from which the entire thorax is suspended, doubles as a conduit for the spinal cord |
| spinal column | provides the points of attachment for numerous muscles by means of various processes; houses the spinal cord, with spinal nerves emerging and entering the spinal cord through spaces between the vertebrae |
| Five divisions of the vertebral column | cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, coccyx |
| pelvic girdle | part of bony thorax; located at the base of the vertebral column; structure that attaches legs to the vertebral column |
| pectoral girdle | part of bony thorax; permits attachment of upper extremities to the vertebra column; comprised of the scapula and clavicle |
| scapula | part of pectoral girdle (which is part of bony thorax); shoulder blade |
| clavicle | also, “collarbone,” part of pectoral girdle (which is part of bony thorax); provides the anterior support for the shoulder |
| sternum | part of bony thorax; “breastbone;” anterior place of attachment for the ribs |
| bony thorax | comprised of the pectoral girdle (scapula and clavicle), the sternum, the ribs and their attachments to the vertebral column, and the pelvic girdle; the cavity in which the lungs are located |
| trachea | part of visceral thorax; provides communication between the external and internal environments; part of the bronchial passageway |
| carina | site of the first bifurcation of the trachea into the two mainstem bronchi |
| esophagus | a long collapsed tube running behind and adjacent to the trachea; provides the conduit to the digestive system |
| esophagus | retains its collapsed condition except when occupied by a bolus of food; passageway through which a bolus of food is propelled by gravity and peristaltic contractions to the stomach |
| bronchial tree | characterized by increasingly smaller tubes as one progresses into the depths of the lungs |
| terminal bronchiole | final tube in the bronchial tree; end tube; smaller than 1 mm in diameter; location of alveoli |
| alveoli | minute air sacs located deep within the lungs; where gas exchange happens; characterized by extremely thin membrane which is permeable to both oxygen and carbon dioxide given proper circumstances |
| alveolus | also, air sac; the point where carbon dioxide is translated out of the blood stream and oxygen is translated into the bloodstream; has extremely thin wall which promotes rapid transfer of gas across the membrane |
| surfactant | produced by some cells; a substance which reduces the surface tension to keep the alveoli from collapsing during respiration |
| pleural lining | provides a mechanism for translating the force of thorax enlargement into inspiration |
| Two types of pleural linings | visceral (covering the lungs) and parietal (covering other structures) |
| Types of parietal pleurae | thoracic, mediastinal, pericardial, diaphragmatic, costal, apical |
| pleurisy | a condition in which the pleural linings of the thoracic cavity are inflamed or lack of lubricants |
| diaphragm | primary muscle of respiration; takes the form of an inverted bowl; striated muscles; has attachments along the lower margin of the rib cage, sternum, and vertebral column |
| abdominal aponeurosis | sheet-like tendon that comprises the central tendon of the diaphragm |
