Label the diagram.
The diaphragm separates the thoracic cavity from the abdominal cavity.
What is the space between two pleural cavities?
Mediastinum
Pleural Space
Hilum
Lobe
The trachea is 1/2 1( 1/2, 1 ) inches in diameter and 4.5 5( 4.5, 5 ) inches in length.
The last tracheal cartilage is called the carina.
The LEFT primary bronchus is shorter, wider, and more vertical than the RIGHT primary bronchus.
Foreign bodies are more likely to pass into the right bronchus than the left bronchus.
The trachea divides, or bifurcates, into two lesser tubes called the _____?
Primary bronchi
Bronchioles
Alveolar duct
Alveolar sac
Oxygen and carbon dioxide are exchanged by diffusion within the walls of the _____?
Alveoli
The lungs remove carbon dioxide from the body.
The left lung is shorter and broader than the right lung.
What is a double-walled, serous membrane sac?
Pleura
Alveolar Sac
Carina
The inner layer of the pleural sac is called the Visceral Parietal( Visceral, Parietal ) pleura and outer layer is called the Parietal Visceral( Parietal, Visceral ) pleura.
The horizontal fissure divides the lungs into superior and inferior lobes.
The left lung has no horizontal fissure.
The carina is a tongue-shaped process on the anteromedial border of the left lung. It fills the space between the chest wall and the heart.
Which part of the thoracic cavity contains all thoracic organs except the lungs and pleurae?
Pleural Cavity
Abdominal Cavity
Which bony structure forms the anterior border of the mediastinum?
Sternum
Scapulae
Clavicle
Thoracic vertebral column
Which structures branch from the distal end of the trachea?
Tertiary Bronchi
Primary Bronchi
Secondary Bronchi
Where do vessels enter a lung?
The aorta is a mediastinal blood vessel.
What is the name of the superior portion of each lung?
Apex
Base
What mediastinal structure consists of C-shaped cartilaginous rings?
Trachea
Esophagus
Pharynx
Larynx
The thymus gland controls the lymphatic system.
The thymus gland reaches its maximum size during adolescence.
❌ A collapse of all or part of a lung ❌ Condition of unknown origin often associate with pulmonary fibrosis ❌ Destructive and obstructive airway changes leading to an increased volume of air in the lungs ❌ Collection of fluid in the pleural cavity ❌ Replacement of air with fluid in the lung interstitium and alveoli
Lobar (bacterial pneumonia) is pneumonia involving the alveoli of an entire lobe without involving the bronchi.
