pulmonary contusion and laceration are injuries to the lung tissue. pulmonary laceration, in which lung tissue is torn or cut, differs from pulmonary contusion in that the former involves disruption of the macroscopic architecture of the lung, while the latter does not. when lacerations fill with blood, the result is pulmonary hematoma, a collection of blood within the lung tissue. contusion involves hemorrhage in the alveoli (tiny air-filled sacs responsible for absorbing oxygen), but a hematoma is a discrete clot of blood not interspersed with lung tissue. a collapsed lung can result when the pleural cavity (the space outside the lung) accumulates blood (hemothorax) or air (pneumothorax) or both (hemopneumothorax). these conditions do not inherently involve damage to the lung tissue itself, but they may be associated with it. injuries to the chest wall are also distinct from but may be associated with lung injuries. chest wall injuries include rib fractures and flail chest, in which multiple ribs are broken so that a segment of the ribcage is detached from the rest of the chest wall and moves independently.

the ancient or early name for the site of mecca is "bakkah" (, also transliterated baca, baka, bakah, bakka, becca, bekka, etc.). an arabic language word, its etymology, like that of mecca, is obscure. widely believed to be a synonym for mecca, it is said to be more specifically the early name for the valley located therein, while muslim scholars generally use it to refer to the sacred area of the city that immediately surrounds and includes the "ka‘bah" (, kaaba). this form is used for the name mecca in the quran in 3:96, while the form mecca is used in 48:24. in south arabic, the language in use in the southern portion of the arabian peninsula at the time of muhammad, the "b" and "m" were interchangeable. other references to mecca in the quran (6:92, 42:5) call it "umm al-qurā" (), meaning "mother of all settlements"/"mother of villages". another name of mecca is "ṫihāmah" ().
