What sucks in air and pass it down into the bronchi?

Well, the lungs do the actual "sucking". However, the air enters through the external nares (nostrils) of the nose, the nasal cavity, pharynx (throat) and trachea (windpipe) before reaching the bronchi.


What does air pass through after the trachea?

After the trachea, air goes into the primary bronchi, then interpulmonary bronchi, then bronchioles, then terminal bronchioles, then into the alveoli.


What are the last tubes the air travels through before the alveoli?

what are the 2 pipes air pass through before reaching the alveoli ?


What structures does air pass through as it travels to the lungs?

The nose, pharynx, trachea, and bronchi.


What travels through the bronchi?

Bronchi carries air to lung. Mainly o2 and co2.


Which structures bring oxygen from the trachea to the lungs?

Trachea divides in 2 bronchi which conducte air into the lungs (inside the lungs each bronchi divides in many smaller branchs only studied in college)


What structure allows air to pass between the larynx and bronchi?

The structure that allows air to pass between the larynx and bronchi is the trachea. The trachea, also known as the windpipe, is a tubular structure made of cartilage and smooth muscle that extends from the larynx down to the bronchi, facilitating the flow of air to and from the lungs. It branches into the right and left bronchi, which lead to the respective lungs.


Work of breathing?

Once you breathe in oxygen through your nose, it travels through the trachea, then to the bronchi. The bronchi helps to get oxygen to your lungs. After the air passes through the bronchi, it travels through the bronchioles which are smaller tubes than the bronchi which are bigger tubes than the bronchioles. From the bronchioles air goes to the alveoli. Then it travels back out through the bronchioles, then through the bronchi until the carbon dioxide waste is out of your system. Hope i helped :)


Where does expired air go after the bronchi?

After passing through the bronchi, expired air moves into the bronchioles, which are smaller air passages within the lungs. From the bronchioles, the air then travels to the alveoli, where gas exchange occurs. Once the oxygen in the air is depleted and carbon dioxide is present, the expired air travels back through the bronchioles and bronchi, eventually exiting the body through the trachea and mouth or nose.


What is the of the bronchi?

Air travels to and from the lungs though two branches of the trachea called bronchi (one branch equals bronchus; 2 is bronchi). The bronchi subdivide within the lobes of the lungs into smaller and smaller air vessels called bronchioles or bronchioli (singular), that terminate in alveoli. When the alveoli inflate with inhaled air brought in through the bronchi, oxygen enters into the blood. When air is exhaled through the bronchi, the alveoli deflate to expel carbon dioxide and other waste gases from the blood.


When you inhale air goes through the what before it enters the bronchi?

trachea


What is the path a breath of air will take from inhalation to exhalation?

Air will enter the nostrils or oral cavity, pass through the nasopharynx, pass through the oral pharynx and through the glottis into the trachea, enter either the right or left bronchi, travel into the bronchioles, and be absorbed to the blood stream at the alveoli. Carbon dioxide will reverse this path to the point of exhalation.
