Question

What is the function of larynx trachea bronchi and lungs in humans?

Answer 1

The lungs are a pair of air-filled, spongy organs on either side of the chest (thorax). Via tubular branches called bronchi, the trachea (windpipe) transports inhaled air into the lungs.

Complete answer:
The lungs are a pair of air-filled, spongy organs on either side of the chest (thorax). Via its tubular branches, known as bronchi, the trachea (windpipe) transports inhaled air into the lungs. The bronchi divide further into smaller and smaller branches (bronchioles) until they are microscopic.
The larynx, also known as the voice box, is a neck organ that helps with breathing, generating sound, and protecting the trachea from food aspiration. The laryngeal inlet, which connects the larynx to the pharynx, is about 4–5 centimetres in diameter.
The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing air to move through. It is found in almost all air-breathing species. From the larynx, the trachea divides into the two main bronchi.
The bronchi are the airways that run from the trachea into the lungs, branching off into smaller structures until they meet the alveoli, which are tiny sacs that allow oxygen and carbon dioxide to be exchanged in the lungs.

Note:
The respiratory system performs two critical functions: it transports oxygen into our bodies, which our cells need to survive and work properly, and it aids in the removal of carbon dioxide, which is a waste product of cellular function.
