Respiratory system anatomy Physiology Medical Biology Diagrams Explore the anatomy of lung lobes and fissures, their roles in respiratory function, and the differences between the right and left lungs. TMC Practice Exam; Courses; Divides the superior and middle lobes. The bronchial tree of the right lung is more vertical and wider than the left, making it more prone to inhaled objects getting trapped.
Anatomy. The lungs are highly specialized organs with a complex structure designed for efficient gas exchange. Below is a detailed exploration of their anatomy. Gross Anatomy. Lobes: The lungs are divided into lobes. The right lung has three lobes—superior, middle, and inferior—while the left lung has two lobes—superior and inferior. The

Gross anatomy. The trachea divides at the carina forming the left and right main stem bronchi which enter the lung substance to divide further. This initial division is into secondary or lobar bronchi, but subsequent divisions give rise to smaller and smaller bronchi and bronchioles until the smallest bronchioles connect to the innumerable alveoli.. Each segment has its own pulmonary arterial Bronchopulmonary segments of left lung by Anatomy.app . Lung histology. Microscopically, the lungs bear a strong resemblance to the structure of an alveolar gland. The lungs contain two parts (also known as trees) - bronchial and alveolar trees. Most of the bronchial tree extends into the lungs, but it does not form the lung parenchyma. It is

Lung Segments and Bronchi Biology Diagrams
Master the lungs anatomy with our study units: Each bronchopulmonary segment is served by corresponding branches of the bronchial tree, along with their own arterial supply. However, The secondary bronchi supply the lobes of the lung, while the segmental branches will deliver oxygen to the respective segments. Superior and inferior The left lung has two lobes and one fissure; while the right lung has three lobes and two fissures. The lobes are then further subdivided into bronchopulmonary segments; such that the left lung has 9 - 10 segments, while the right lung has 10. Between lobes are interlobar surfaces of lungs which are separated by fissures of the lungs.
