What is the passage for both air and food?

What is the passage for both air and food?

The oropharynx is the common passage for food and air. Liquid, food and air all pass through this passage. Initially, even though air enters through the nasal cavity and food, water enters through the oral cavity, the two passages unite at a point to form the structure – oropharynx.

What is the common passage for both the respiratory and digestive systems food and gases for breathing?

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.

Is a common passageway for both respiration and digestion?

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.

Is the common passage for air and food in humans?

The common passage for food and air is the oropharynx. All food, liquid, and air pass through this. Even though the passage of food and water and the passage of air are separated at the beginning, that is air enters through the nasal cavity, and water and food enter through the oral cavity.

What is the movement of air into and out of the lungs called?

Pulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation).

Where does the respiratory system meet the digestive system?

The two openings of the airway (the nasal cavity and the mouth) meet at the pharynx (pronounced: FAR-inks), or throat, at the back of the nose and mouth. 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, the pathway for both food and air divides in two.

How are the organs of the respiratory system involved in breathing?

All of the organs of the respiratory system are involved in breathing, but only the lungs are involved in gas exchange. The organs of the respiratory system form a continuous system of passages called the respiratory tract, through which air flows into and out of the body.
