Final answer:
The trachea, or windpipe, is the main tubular structure in the neck that carries air to and from the lungs.
Step-by-step explanation:
The main tubular structure in the neck region that carries air to and from the lungs is the trachea. The trachea, also known as the windpipe, is a vital component of the respiratory system. After air passes through the larynx, or voice box, it enters the trachea, a long tube that extends down to the chest and eventually divides to form the right and left bronchi, which are supported by cartilage to prevent collapse. The bronchi then branch into smaller bronchioles that end in the alveoli, where gas exchange occurs. Throughout its length, the trachea is lined with mucus-producing goblet cells and ciliated epithelia that help to trap and move foreign particles towards the pharynx to be expelled from the body.
The trachea is the main tubular structure in the neck region that carries air to and from the lungs. Also known as the windpipe, it is a long, cylindrical tube made of incomplete rings of cartilage and smooth muscle. The trachea funnels inhaled air to the lungs and exhaled air out of the body, and is lined with cilia and mucus-secreting cells that help to trap particles and move them towards the throat.
