What else can I help you with?
What closes and seals the lower airway during swallowing?
epiglottis
What divides the upper and lower airway?
The glottis is dividing line between the upper and lower airway
What is in the upper airway?
The nose, pharynx, and trachea are the parts of the upper airway. The tubes of the lungs comprise the lower airway.
Are the larynx part of the airway to the brochi?
Yes, the larynx is part of the airway that connects the pharynx (throat) to the trachea, which then leads to the bronchi in the lungs. The larynx is often referred to as the voice box and plays a key role in producing sound and protecting the lower airway during swallowing.
What is a compromised neonate?
Compromised neonate is a medical term used to describe an airway that is restricted or blocked. This can either be in the upper airway or the lower airway.
Does the tracheal ring support the entire lower airway?
No.
Is the larynx a part of the respiratory system explain?
Yes, the larynx is part of the respiratory system because it contains the vocal cords that produce sound during breathing. It also plays a role in protecting the lower airway from foreign particles by closing off the airway during swallowing.
What is the lid of the lower respiratory tract?
The lid of the lower respiratory tract is the epiglottis. It is a flap of cartilage that covers the entrance to the larynx during swallowing to prevent food or liquids from entering the airway.
Is the entire lower airway supported by tracheal rings?
The entire lower airway is supported by c shaped cartilaginous rings. These rings hold the passageway open and get smaller when air exchange is made.
What marks the entrance to the lower airway?
The trachea, also known as the windpipe, marks the entrance to the lower airway. It is a rigid tube that connects the larynx to the bronchi and allows for the passage of air into the lungs.
When giving mouth to mouth resusitation why is the head held back and the lower jaw upward?
Holding the head back and lifting the lower jaw helps to open the airway and allow for better air flow during mouth-to-mouth resuscitation. This position helps ensure that the person's airway remains clear and unobstructed for effective breathing support.
What happened to the FEV1 percent as the radius of the airways was decreased?
FEV 1 (%) will decrease as the airway radius is decreased. FEV 1 (%) is the amount of air that can be expelled from the lungs in one second during forced expiration. If the airway becomes smaller, then the resistance to airflow will increase and FEV 1 (%) will become lower.
