Which type of airway supplies air to a lobe of the lung? <\/p>\n\n\n\n
a) primary bronchus <\/p>\n\n\n\n
b) trachea <\/p>\n\n\n\n
c) secondary bronchus <\/p>\n\n\n\n
d) bronchioles<\/p>\n\n\n\n
e) tertiary bronchus<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Correct Answer: c) secondary bronchus<\/strong><\/p>\n\n\n\n The secondary bronchus, also known as the lobar bronchus, is the airway that directly supplies air to a specific lobe of the lung. Each lung is divided into lobes. The right lung has three lobes\u2014superior, middle, and inferior\u2014while the left lung has two lobes\u2014superior and inferior. For each of these lobes, there is a corresponding secondary bronchus.<\/p>\n\n\n\n The respiratory system starts at the trachea, a large airway that conducts air from the mouth and nose into the lungs. The trachea branches into two primary bronchi\u2014one for each lung. These primary bronchi enter the lungs and then split into secondary bronchi. Each secondary bronchus enters a specific lobe of the lung and further divides into smaller tertiary bronchi, also called segmental bronchi. These then branch into even smaller tubes called bronchioles, which ultimately lead to the alveoli where gas exchange occurs.<\/p>\n\n\n\n The function of the secondary bronchus is to ensure that each lobe receives adequate airflow. By having one bronchus per lobe, the lungs can localize ventilation, which is important if a disease or obstruction affects a particular lobe. This structure also allows for more effective surgical interventions, such as lobectomies, where an individual lobe may be removed without disturbing the others.<\/p>\n\n\n\n To clarify the other options:<\/p>\n\n\n\n Therefore, the secondary bronchus<\/strong> is the correct answer, as it is responsible for directing air into each lobe of the lung.<\/p>\n","protected":false},"excerpt":{"rendered":" Which type of airway supplies air to a lobe of the lung? a) primary bronchus b) trachea c) secondary bronchus d) bronchioles e) tertiary bronchus The correct answer and explanation is: Correct Answer: c) secondary bronchus The secondary bronchus, also known as the lobar bronchus, is the airway that directly supplies air to a specific […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-35120","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/35120","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=35120"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/35120\/revisions"}],"predecessor-version":[{"id":35121,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/35120\/revisions\/35121"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=35120"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=35120"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=35120"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
