Respiratory System Practice Sheet
Introduction to the Respiratory System
The respiratory system is responsible for taking in oxygen from the atmosphere and releasing carbon dioxide. It is composed of organs and structures that work together to accomplish this task.
The main organs of the respiratory system are the lungs, the trachea, the diaphragm, and the nose. The lungs are responsible for taking in oxygen and releasing carbon dioxide. The trachea is a tube that connects the lungs to the nose. The diaphragm is a muscle located between the lungs and the abdomen that helps to regulate breathing. The nose is responsible for filtering and warming the air that is breathed in.
Anatomy of the Respiratory System
The respiratory system is composed of several different parts. The main parts are the lungs, the trachea, the diaphragm, and the nose.
The lungs are the main organs of the respiratory system. They are responsible for taking in oxygen and releasing carbon dioxide. The lungs are made up of many small air sacs called alveoli. The alveoli are responsible for the exchange of oxygen and carbon dioxide between the lungs and the atmosphere.
The trachea is a tube that connects the lungs to the nose. It is made up of several rings of cartilage that help to keep it open.
The diaphragm is a muscle located between the lungs and the abdomen. It helps to regulate breathing by expanding and contracting.
The nose is responsible for filtering and warming the air that is breathed in. It is also responsible for producing mucus, which helps to keep the airways clean.
Functions of the Respiratory System
The respiratory system is responsible for taking in oxygen and releasing carbon dioxide. It is also responsible for producing mucus, which helps to keep the airways clean.
The process of breathing involves the expansion and contraction of the lungs. When the lungs expand, air is drawn in. When the lungs contract, air is expelled. This process is regulated by the diaphragm.
The nose is responsible for filtering and warming the air that is breathed in. It is also responsible for producing mucus, which helps to keep the airways clean.
