Label the features of the tissue.

pseudostratified ciliated columnar

– The process of moving air in and out of the lungs, including both inhalation and exhalation. It ensures the exchange of oxygen and carbon dioxide between the lungs and the atmosphere. – The active phase of ventilation where air is drawn into the lungs. This occurs when the diaphragm contracts and the rib cage expands, creating a negative pressure that pulls air into the alveoli. – The passive (or sometimes active) phase of ventilation where air is expelled from the lungs. This happens when the diaphragm relaxes and the rib cage moves inward, increasing pressure in the lungs and forcing air out. – The total volume of air moved in and out of the lungs per minute. It is calculated as Tidal Volume × Respiratory Rate (breaths per minute) .

Minute Respiratory Volume (MRV)

Inspiratory Reserve Volume (IRV)

Expiratory Reserve Volume (ERV)

– The amount of air that is inhaled or exhaled in a single, normal breath at rest. It is typically around 500 mL in an average adult. – The maximum amount of air that can be exhaled after a maximum inhalation. It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. – The additional amount of air that can be forcefully exhaled after a normal exhalation. – The additional amount of air that can be forcefully inhaled after a normal inhalation. – The amount of air that remains in the lungs after a forceful exhalation. This air prevents lung collapse and maintains alveolar inflation.

Expiratory Reserve Volume (ERV)

Inspiratory Reserve Volume (IRV)

Minute Respiratory Volume (MRV)

Match the descriptions with their functions: 1. Facilitates rapid diffusion of gases in the lungs (alveoli). 2. Allows efficient exchange of oxygen and carbon dioxide. 3. Reduces friction by providing a smooth surface. 1. Moves mucus and trapped particles out of the respiratory tract. 2. Helps protect the lungs from dust, bacteria, and debris . 1. Provides structural support to keep airways open. 2. Prevents collapse during inhalation and exhalation. 3. Allows flexibility for airway expansion. 1. Increases surface area for humidifying and warming air. 2. Traps dust and pathogens in mucus. 3. Directs airflow to improve olfaction (sense of smell). 1. Act as immune defense structures that trap pathogens. 2. Produce white blood cells to fight infections. 3. Help prevent infections from reaching the lower respiratory tract .

Cartilage in the Walls of Air Passageways

What is the general appearance of lung tissue under low power magnification?

Sponge-like with many air pockets

Highly vascularized dense tissue

What is the general appearance of the epiglottis?

Leaf-shaped flap with cartilage support

Sponge-like tissue covered in capillaries

Is the epiglottis more directly involved in directing the movement of air or food? Explain.

Food, because it prevents food from entering the trachea

Air, because it regulates airflow into the lungs

Air, because it prevents food from entering the trachea

Food, because it regulates airflow into the lungs

What type of tissue lines the insides of blood vessels?

Pseudostratified columnar epithelium

What type of tissue lines the inside of most air passageways?

Pseudostratified columnar epithelium
