In 3-5 sentences, describe the human respiratory system and its functions.(4 points)

The human respiratory system is a complex network of organs and tissues that help in the process of respiration. It includes the lungs, bronchial tubes, trachea, nose, and mouth. The primary function of the respiratory system is to exchange oxygen and carbon dioxide between the body and the environment, allowing for the intake of oxygen and the removal of carbon dioxide waste. Additionally, it helps regulate the pH levels in the body and plays a role in vocalization.

The human respiratory system is responsible for the exchange of oxygen and carbon dioxide between the body and the environment. It consists of the nose, pharynx, larynx, trachea, bronchi, and lungs. The main functions of the respiratory system include breathing in oxygen and releasing carbon dioxide, filtering and humidifying the air we breathe, and helping to regulate the body's pH levels.

The human respiratory system is responsible for the exchange of gases between the body and the environment. It consists of the lungs, airways (such as the trachea and bronchi), and muscles involved in breathing. The main functions of the respiratory system are to bring oxygen into the body and remove carbon dioxide, which is a waste product of cellular respiration. This process occurs through inhalation, where oxygen is taken in, and exhalation, where carbon dioxide is expelled.
