Final answer:
The term for a breathing tube is an endotracheal tube. This tube is key to the intubation process, allowing air to reach the lungs when the respiratory tract is obstructed. The respiratory system includes the nasal cavity, pharynx, trachea, and lungs, with the trachea being the main airway leading to the lungs. Therefore, the correct option is 3.
Step-by-step explanation:
Alternate Term for a Breathing Tube
The alternate term for a breathing tube is endotracheal tube. An endotracheal tube is used during the process of intubation, which is a medical procedure performed by healthcare professionals, such as ambulance crews, when a person's respiratory system is blocked. This tube is placed directly into the respiratory tract through the mouth or nose to ensure that air can bypass any obstruction and reach the lungs.
The respiratory system primarily includes the following four organs: nasal cavity, pharynx, trachea, and lungs. The trachea, also known as the windpipe, is a tubular organ that carries air between the larynx and bronchi and is essential for pulmonary ventilation. This system of airways, including the bronchus and bronchioles, leads to alveoli where gas exchange occurs. Notably, the trachea in humans is different from the one referenced in terrestrial arthropods, which consist of tubules and spiracles.
