Which respiratory organ normally allows both air and food passage?

pharynx Which respiratory organ normally allows both air and food passage? ( ) bronchi ( ) trachea ( ) larynx ( ) pharynx ( ) nasal cavity pharynx Food is prevented from entering the trachea by the epiglottis. The Adam's apple is actually a part of the larynx.

What is the function of the respiratory system in humans?

Their respiratory system consists of traacheae, which are tiny air tubes that take oxygen directly to the cells C. A countercurrent mechanisms ensures that the maximum amount of oxygen is absorbed from the environment B. Their respiratory system consists of traacheae, which are tiny air tubes that take oxygen directly to the cells

What is the correct order of the respiratory system?

nasal cavity → pharynx → glottis → larynx → trachea → bronchi → bronchioles → alveoli (NPGLTBiBioA) Which portion of the respiratory tract is commonly referred to as the "throat"? ( ) pharynx ( ) larynx ( ) glottis ( ) trachea ( ) epiglottis pharynx Which respiratory organ normally allows both air and food passage? ( ) bronchi ( ) trachea

What is the role of the air in the lungs?

( ) warming incoming air before it reaches the lungs ( ) moistening incoming air ( ) filtering out dust and water particles ( ) conducting air with higher O2 to lungs and conducting air with higher CO2 back out ( ) transferring and extracting nutrients

Where in the respiratory system does air water and food pass through?

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.

Which organ in the respiratory system is responsible for keeping food from entering the lungs?

The epiglottis (eh-pih-GLAH-tus), a small flap of tissue, covers the air-only passage when we swallow, keeping food and liquid from going into the lungs.

What are the correct pathway of air in respiratory system?

Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

What are the 7 organs of respiratory system?

What makes up the respiratory system?Nose.Mouth.Throat (pharynx)Voice box (larynx)Windpipe (trachea)Airways (bronchi)Lungs.

What are bronchioles?

Bronchioles are air passages inside the lungs that branch off like tree limbs from the bronchi—the two main air passages into which air flows from the trachea (windpipe) after being inhaled through the nose or mouth. The bronchioles deliver air to tiny sacs called alveoli where oxygen and carbon dioxide are exchanged.

What are alveoli?

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.

Which structure has functions in both the respiratory system and the digestive system?

Pharynx (Throat) The pharynx, usually called the throat, is part of the respiratory system and digestive system. It carries air, food and fluid down from the nose and mouth.

What organs does air travel through?

The respiratory system includes the nose, mouth, throat, voice box, windpipe, and lungs. Air enters the respiratory system through the nose or the mouth. If it goes in the nostrils (also called nares), the air is warmed and humidified.

Which part of the respiratory system is correctly paired with its function?

Alveoli represent one of the significant parts of the respiratory system, which is correctly paired with its function because alveoli are the tiny...

What serves as a passageway for both air and food?

The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid.

Is the diaphragm?

The diaphragm is a muscle that helps you inhale and exhale (breathe in and out). This thin, dome-shaped muscle sits below your lungs and heart. It's attached to your sternum (a bone in the middle of your chest), the bottom of your rib cage and your spine.

What is the main organ of the respiratory system?

the lungsThe main organ of the respiratory system is the lungs. Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).

What is the name of the process of air entering and exiting the lungs?

The entrance and exit of air into and out of the lungs is called. ventilation. The type of respiration in which gases are exchanged between the blood and tissue fluid is termed. internal respiration. You are looking at a structure in the respiratory tract that is filled with small sacs or air pockets.

Does Expired Air contain more carbon dioxide than the air?

Expired air contains less oxygen but more carbon dioxide. The exchange of gases between the lungs and the blood occurs by the process of. diffusion. Blood in the pulmonary (lung) capillaries has a higher partial pressure of carbon dioxide than atmospheric air. True.

What is the respiratory system?

Their respiratory system consists of traacheae, which are tiny air tubes that take oxygen directly to the cells. C. A countercurrent mechanisms ensures that the maximum amount of oxygen is absorbed from the environment.

Which passageway is the passageway to the larynx by which air enters the trachea?

The glottis is the passageway to the larynx by which air enters the Trachea. C. Food and air both enter the pharynx, presenting a potential danger to respiration. D. Air reaching the lungs has been warmed to the body temperature by passage through the nose and upper respiratory passageways.
