The lungs expand drawing in air through the mouth or the nose.
The trachea is the part of the respiratory tract also known as the windpipe. It connects the larynx to the bronchi and allows air to pass in and out of the lungs.
The trachea is commonly known as the windpipe. It is a tube that connects the larynx to the bronchi in the lungs, allowing air to pass through during breathing.
Air entering your body goes from the mouth and nose through the pharynx and into the trachea.
The common name for the trachea is the windpipe. It is a tube-like structure that connects the larynx to the bronchi in the respiratory system, allowing air to pass to and from the lungs.
The bronchi are tubes in the respiratory system that carry air from the trachea to the lungs. They help to distribute air to the different parts of the lungs, where oxygen is taken in and carbon dioxide is released. The bronchi also help to filter and humidify the air before it reaches the lungs. Overall, the bronchi play a crucial role in the process of breathing by ensuring that oxygen is delivered to the body and carbon dioxide is removed efficiently.
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.
After the trachea, air goes into the primary bronchi, then interpulmonary bronchi, then bronchioles, then terminal bronchioles, then into the alveoli.
what are the 2 pipes air pass through before reaching the alveoli ?
The nose, pharynx, trachea, and bronchi.
Bronchi carries air to lung. Mainly o2 and co2.
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)
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.
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 :)
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.
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.
trachea
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.
