Respiratory System Quiz

Part of the respiratory system where gas exchange occurs; composed of bronchioles, alveolar ducts, and alveoli.

Part of the respiratory system that includes structures for air passage, such as the nose, nasal cavity, pharynx, and trachea, but not for gas exchange.

Process of moving air into and out of the lungs.

Gas exchange between the lungs and the blood.

Gas exchange between systemic blood vessels and tissues.

The overall process involving four distinct processes (ventilation, external respiration, transport, and internal respiration) to supply the body with oxygen and dispose of carbon dioxide.

Internal space within the nose; contains respiratory mucosa that moistens and warms air.

Mucous membrane lining much of the nasal cavity, responsible for trapping particles from the air.

Enzyme in nasal mucus that helps destroy bacteria.

Warming, moistening and filtering air entering the respiratory system.

The pharynx is divided into three sections: nasopharynx, oropharynx, and laryngopharynx.

The nasopharynx is a passage for air only and prevents food from entering the nasal cavity during swallowing.

The oropharynx is a common passageway for both air and food.

The laryngopharynx is also a common passageway for both air and food. It leads to the larynx.

The larynx has hyaline cartilage, including thyroid cartilage (Adam's apple) and cricoid cartilage.

The epiglottis is a flap of elastic cartilage that covers the larynx entrance during swallowing.

The pharynx is a funnel-shaped tube connecting the nasal cavity, mouth, larynx, and esophagus, extending from the skull to the 6th cervical vertebra.

Open into the nasopharynx and connect the middle ear to the throat.

Elastic fibers that form the voice box.

Mucosal folds acting as vibrating structures for sound production during breathing.

The opening between the vocal folds, where air passes through to create voice.

Mucosal folds above true vocal cords that play no role in sound production.

Inner lining of the trachea containing mucus-producing and sweeping cells.

Connective tissue layer beneath the trachea's mucosa.

Outermost layer of the trachea, composed of C-shaped cartilage rings.

Air passages branching from the trachea, distributing air to the lobes of the lungs.

The intricate branching system of tubes in the lungs.

Small air passages in the lungs lacking cartilage and mucus-producing cells, but with extensive smooth muscle.

Tiny air sacs in the lungs where gas exchange occurs.

Part of the respiratory system composed of alveoli.

Part of the respiratory system where gas exchange happens.

The thin structure where gas exchange occurs between air and blood.

Two organs in the thoracic cavity involved in gas exchange.

A cavity in the left lung that accommodates the heart.

Thin membranes covering the lungs and the inner wall of the chest cavity.

The act of taking air into the lungs.

The act of expelling air from the lungs.

The process of moving air into and out of the lungs.

The relationships between air pressure in the lungs and outside air that affect breathing.

Funnel-shaped tube connecting nasal cavity/mouth to larynx/esophagus.

Part of pharynx, air passage only, above soft palate.

Part of pharynx, common passage for food and air.

Part of pharynx that connects to larynx.

Voice box; connects pharynx to trachea.

Hyaline cartilage—thyroid (Adam's apple) and cricoid.

Elastic cartilage that covers larynx inlet during swallowing.

Elastic fibers in larynx that form vocal cords.

The respiratory system has two zones: a conducting zone for air passage and a respiratory zone for gas exchange.

The respiratory zone is composed of bronchioles, alveolar ducts, and alveoli. These structures are essential for gas exchange.

The conducting zone consists of the nose, nasal cavity, pharynx, and trachea.

The respiratory system delivers oxygen and removes carbon dioxide from the body.

The process of moving air into and out of the lungs.

Gas exchange between the lungs and the blood.

Gas exchange between blood and body tissues.

The nose provides an airway, moistens and warms air, filters it, and houses olfactory receptors.

The mucous membrane lining much of the nasal cavity, secreting mucus to trap particles and contains lysozyme.

Mucosal folds that vibrate to produce sound when air passes through the glottis

The opening between the vocal cords

Mucosal folds above the true vocal cords, not involved in sound production

Inner lining of the trachea with goblet cells and ciliated epithelium

Connective tissue layer beneath the trachea's mucosa

Outer layer of the trachea with C-shaped cartilage rings

Air passages branching from the trachea, leading to the lungs.

The complex branching system of tubes within the lungs

Small air passages in the lungs, lacking cartilage and mucus-producing cells but having smooth muscle

Tiny air sacs in the lungs where gas exchange takes place

Part of lungs containing alveoli, where gas exchange happens

Part of the respiratory system where gas exchange happens; includes bronchioles, alveolar ducts, and alveoli.

Thin barrier between air in alveoli and blood in capillaries, facilitating gas exchange.

Main organs of the respiratory system, responsible for gas exchange.

Indentation on the left lung to accommodate the heart.

Double-layered membrane surrounding the lungs.

The act of breathing air into the lungs.

The act of breathing air out of the lungs.

Process of moving air in and out of the lungs.

Relationship between air pressure inside and outside the lungs that drives breathing.
