RESPIRATORY SYSTEM STUDY SHEET
Objectives:
Terns to Know:
The Parts and Path of Air
The respiratory system moves air in and out of the body. It works closely with the circulatory system. Air enters the body through the nose and mouth and then moves to the pharynx, or throat. Air moves from the throat to the larynx, or voice box. The Epiglottis is a flap of skin that protects the larynx from food and liquid. Air then continues to the trachea. The trachea is the pipe that carries air deep into the body. The lower end of the trachea splits into two branches called bronchi. The bronchi carry the air to and from the two lungs.
A lung is a sponge-like organ that allows gases to pass between blood and air. In the lungs, the bronchi branch off into smaller tubes called broncioles. The bronchioles are covered with tiny air sacs called alveoli. Capillaries surround the alveloli, and this is were Oxygen and carbon dioxide are exchanged.
Gas Exchange
The lungs and the blood exchange oxygen and carbon dioxide in the alveoli. When air enters the alveoli, the oxygen in the air enters the blood through the capillaries.The blood carries this oxygen to the body's cells by way of the circulatory system. Cells use the oxygen to release energy in nutrients. this process produces the waste gas of carbon dioxide. The blood carries carbon dioxide from the cells back to the alveoli . Carbon dioxide leaves the blood through the capillaries. This gas passes into the alveoli as oxygen enters the blood. The carbon dioxide then leaves the body as the lungs exhale.
The Breathing Process:
Air must move in and out of the lungs for the gases to be exchanged. Moving air in and out of the lungs is called breathing. Breathing is both inhaling and exhaling. Inhaling is when the diaphragm (a muscle that separated the chest from the abdomen), contracts. When people exercise, they use more oxygen and breath faster, to get more oxygen and release waste quicker.
Lung Disorders:
Allergies, Asthma, Emphysema, Pneumonia, and Tuberculosis
