What is the passageways of air into the body?

What is the passageways of air into the body?

When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes.

What is the main passageway into and out of the respiratory system?

The trachea, commonly called the windpipe, is the main airway to the lungs. The trachea divides into the right and left primary bronchi, which branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli.

What is the second passageway for air entering the body?

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 is the main passageway to the lungs?

The TRACHEA (windpipe) is the passage leading from your pharynx to the lungs. The RIBS are bones supporting and protecting your chest cavity. They move a small amount and help the lungs to expand and contract. The trachea divides into the two main BRONCHI (tubes), one for each lung.

What is the common passageway for food and air?

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.

Where does the air passageway lead in the human body?

Air passage ways consist of nostrils, nasal cavities, pharynx, larynx, trachea, bronchi, bronchioles and alveolar ducts which ultimately lead into the alveolar sac. Air passageway opens to exterior via opening called nostrils.

How does the body send water through the body?

Your hydration level determines how quickly your body will send water to your kidneys, which then goes to the bladder once it gets processed as urine. If you’re very hydrated, your body will send the excess water into the kidneys quickly because it’s not needed elsewhere.

Where does air enter and exit the nasal cavity?

Air passageway opens to exterior via opening called nostrils. Nasal cavities are lined with mucous membrane of ciliated epithelium. Each nasal cavity is subdivided into three passage ways by the projection of bones from the walls of the internal nose. Nasal cavities perform the following functions: Air enters the nasal cavity through nostril.

Which is the last passageway in the respiratory system?

Bronchioles: Bronchioles are the finest conducting pathways within the respiratory system. These bronchioles are the last passageway for air before it reaches the alveoli, where it then is combined with blood that is first pumped back to the heart, and then circulated throughout the rest of the body. Alveoli:
