Lunge

The video tutorial provides an in-depth look at the anatomy and function of the human lungs. It covers the structure of the right and left lungs, including their lobes and surfaces. The tutorial explains the role of the Hilus and the respiratory ciliated epithelium, highlighting the importance of mucus and cilia in maintaining airway health. It also details the bronchial tree's structure and the process of gas exchange in the alveoli, emphasizing the thin walls that allow for efficient diffusion of gases.

Which lung is larger and how many lobes does it have?

• Right lung with 2 lobes

• Left lung with 3 lobes

• Right lung with 3 lobes

• Left lung with 2 lobes

What separates the lobes of the lungs?

• Oblique fissures

• Horizontal lines

• Vertical partitions

• Circular bands

What is the primary function of the cilia in the respiratory epithelium?

• To transport particles out of the airways

• To release carbon dioxide

• To produce mucus

• To absorb oxygen

What is the role of goblet cells in the respiratory epithelium?

• To absorb nutrients

• To release mucus

• To transport oxygen

• To filter air

Where does the bronchial tree begin?

• At the nasal cavities

• At the tracheal bifurcation

• At the alveoli

• At the diaphragm

How many lobar bronchi are present in the right lung?

• Four

• Three

• Two

• One

What occurs at the alveoli in the lungs?

• Mucus production

• Blood filtration

• Gas exchange

• Nutrient absorption
