Question

What Parts of the Respiratory System Comprises the Lower Respiratory Tract?

Answer 1

Human Respiratory System

1. Human Respiratory System is a network of organs and tissues that helps us breathe.
2. The primary function of this system is to introduce oxygen into the body and expel carbon dioxide from the body.
3. The lower respiratory tract comprises the trachea, bronchi, bronchioles, and alveoli in the lungs.

Trachea:

1. The trachea, commonly known as the windpipe, is the large tube that delivers air from the upper respiratory tract to the bronchi.

Bronchi:

1. Bronchi is plural for bronchus and represent the passageways leading into the lungs.

Bronchioles:

1. The bronchioles serve as a transition between the large cartilage-supported bronchi that enter the lungs and the tiny alveolar ducts that connect directly to the alveoli.
2. The bronchioles carry oxygen-rich air into the lungs and carry carbon dioxide-rich air out of the lungs.

Alveoli:

1. Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going.
2. Alveoli are an important part of the respiratory system whose function is to exchange oxygen and carbon dioxide molecules to and from the bloodstream.
