Write Other Names of Alveolar Sacs, Voice Box


In the field of anatomy, the human body is a complex machine that comprises several organs, each with its own unique structure and function. Two such organs that are of vital importance to the respiratory system and speech production are the alveolar sacs and the voice box.

The content below explores these two organs in detail, including their alternate names, structure, and functions.

Part 1: Alveolar Sacs

Alternate Names

The alveolar sacs are also known as alveolar ducts, alveoli, or pulmonary alveoli. These alternate names refer to the structure and function of these small, balloon-like sacs that make up the lung tissue.


The alveolar sacs are tiny, grape-like structures located at the end of the respiratory bronchioles. They are about 200-300 micrometers in diameter and have a thin membrane that allows for the exchange of gases between the air and blood vessels.

The alveolar sacs are surrounded by a network of capillaries that transport oxygen to the bloodstream and remove carbon dioxide from the body.


The primary function of the alveolar sacs is to exchange gases between the lungs and the bloodstream. Oxygen from the air we breathe diffuses into the bloodstream, while carbon dioxide from the bloodstream diffuses into the air we exhale. This exchange of gases is vital to the respiratory system and helps to maintain the body's homeostasis.

Part 2: Voice Box

Alternate names

The voice box, also known as the larynx, has several alternate names. It is sometimes called Adam's apple, the voice box, or the vocal cords. These names refer to the structure and function of the larynx.


The larynx is located in the neck and sits on top of the trachea, or windpipe. It is made up of several cartilages, including the thyroid cartilage, which gives rise to Adam's apple, and the cricoid cartilage, which is shaped like a signet ring.

Inside the larynx are the vocal cords, which are made up of two thin, elastic membranes that vibrate when air passes through them.


The primary function of the larynx is to produce sound, which is used for speech and communication. The vocal cords vibrate when air passes through them, creating sound waves that are then shaped into speech sounds by the mouth and tongue. In addition to producing sound, the larynx also serves to protect the airways from foreign objects and regulate the flow of air into and out of the lungs.


The alveolar sacs and voice box are two vital organs in the human body, each with its own unique structure and function. Understanding the alternate names, structures, and functions of these organs can help us appreciate the complexity and importance of the respiratory and speech systems.

While these organs may seem small and insignificant, they play a critical role in our daily lives, allowing us to breathe, speak, and communicate with others.
