Which part of the respiratory system serves as the passageway for air food and water?

The pharynx, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.

What are the parts of the respiratory tract?

The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs.

What is divided into passageways called Meatuses?

Superior, middle, and inferior nasal conchae (turbinates) protrude into the nasal cavity from the lateral walls, and divide the cavity into three passageways called meatuses.

Which parts of the pharynx are passageways for both food and air?

oropharynx
The pharynx is divided into three parts: nasopharynx, oropharynx and laryngopharynx. o Nasopharynx- located behind the nasal cavity, it connects the nasal cavity to the oropharynx. laryngopharynx and serves as a passageway for both food and air.

Which part of the respiratory tract divides into two passages?

trachea
Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.

What structure carries both food and air?

pharynx
The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air. At the bottom of the pharynx, this pathway divides in two, one for food — the esophagus (ih-SAH-fuh-gus), which leads to the stomach — and the other for air.

What type of epithelium is in the pharynx?

stratified squamous epithelium
The oropharynx and pharynx proper are lined by largely non-keratinizing stratified squamous epithelium. The nasopharynx is mainly lined by ciliated columnar epithelium but stratified squamous epithelium occurs at its lower end where it joins the oropharynx.

What are the three sections of the pharynx?

It contains three sections: the nasopharynx, oropharynx and laryngopharynx, which is also called the hypopharynx.

What is known as the passageway between the oral cavity and the oropharynx?

pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The pharynx chamber serves both respiratory and digestive functions. The nasal pharynx connects to the second region, the oral pharynx, by means of a passage called an isthmus.

What is the trachea divides into two tubes called?

At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs.

How does food and air separate?

Air, food and liquid all pass through this common passage, the oropharynx. The two passages separate again here, in the hypopharynx. Food and liquid pass backward into the esophagus on their way to the stomach. Air passes forward through the larynx and into the trachea, on its way to the lungs.

What sequence does exhale air flow through the respiratory structures?

First air enters to nose through nostrils. There are two nasal cavities in which hair and mucus are present. Here air is filtered and its temperature changes according to body temperature. Then air passes through pharynx where germs are removed and air moves to larynx then trachea.

Where does respiration take place in the human respiratory system?

Respiration in humans takes place through the lungs. It is the largest organ of the human respiratory system. The air inhaled moves down the trachea into the lungs where oxygen is exchanged for carbon dioxide from the body tissues.

What is the major entrance and exit of the respiratory system?

The major entrance and exit for the respiratory system is through the nose. When discussing the nose, it is helpful to divide it into two major sections: the external nose, and the nasal cavity or internal nose.

What are the organs of the respiratory system and their functions?

Lungs are the primary organs of the respiratory system which help in the exchange of gases. The other main parts of this system include a series of airways for air passages, blood vessels and the muscles that facilitate breathing. Also Read: Mechanism of Breathing.

What structures are in the respiratory zone of the lungs?

Such structures include the nasal cavity, pharynx, larynx, trachea, and most of the bronchial tree. The respiratory zone includes all the organs and structures that are directly involved in gas exchange, including the respiratory bronchioles, alveolar ducts, and alveoli.
