Male respiratory

• The trachea branches into two main bronchi at the carina (bifurcation).
• The trachea branches into two main bronchi at the carina (bifurcation).
• The trachea has C-shaped cartilage rings that keep it open during breathing.
• The trachea is the windpipe, which connects the larynx to the bronchi.
• Each lung is divided by fissures, which are thin membranes that separate lobes.
• Each lung has three lobes separated by horizontal fissures.
• Each lung is divided by fissures, which are membranes that separate lobes.
• The left lung has two lobes separated by an oblique fissure.
• The right lung has an additional oblique fissure separating its upper lobe from the middle and lower lobes.
• The right lung has an additional oblique fissure separating its upper lobe from the middle and lower lobes.
• The trachea is lined with ciliated pseudostratified columnar epithelium, which helps to move mucus upwards towards the pharynx.
• The trachea is lined with ciliated pseudostratified columnar epithelium, which helps to move mucus upwards towards the pharynx.
• The right lung has three lobes separated by oblique and horizontal fissures.
• The right lung has three lobes separated by oblique and horizontal fissures.
• The lungs have pleural cavities between them and the chest wall.
• The left lung has two lobes - upper and lower.
• The right lung has an oblique fissure separating its upper and lower lobes.
• The right lung has three lobes - superior, middle, inferior.
• The left lung has two lobes - upper lobe, lower lobe.
• The trachea is lined with ciliated pseudostratified columnar epithelium.
• The right lung has three lobes - upper lobe, middle lobe, lower lobe.
• The lungs have a smooth outer layer called pleura.
• The right lung has three lobes separated by both an oblique and horizontal fissure.
• The left lung has no oblique fissure because the heart takes up space on the left side.
• The left lung has both an oblique and horizontal fissure separating its superior and inferior lobes.
• The lungs have a smooth outer surface called pleurae.
• Bronchial tubes branch into smaller airways called bronchioles, which end in alveoli.
• The bronchi are divided into smaller branches called bronchioles, which end in alveoli where gas exchange occurs.
• The parietal pleura lines the inside of the thoracic cavity.
• The parietal pleura lines the inside of the thoracic cavity.
• The bronchioles have smooth muscle surrounding them, allowing for contraction during coughing or sneezing.
• The bronchioles have smooth muscle surrounding them, allowing for contraction during coughing or sneezing.
• Bronchial tree refers to all the branches of the trachea down to the alveoli.
• Bronchial tree refers to all the branches of the trachea down to the alveoli.
• Bronchial tubes branch into smaller airways called bronchioles.
• The bronchi are divided into smaller tubes called bronchioles which end at alveoli.
• The lungs have a smooth muscle layer that contracts during expiration to force air out of the alveoli.
• The pleural membrane consists of visceral (inner) and parietal (outer).
• The diaphragm contracts to increase the volume of the thorax during inspiration.
• The bronchioles are the smallest airways that branch off from the terminal bronchiole.
