The ________ brings oxygen into the bloodstream, where it is transported to all body cells
Respiratory system
The process of providing cells with oxygen is commonly known as
Respiration
In addition to bringing oxygen into the bloodstream, the ___________ also removes the waste product, carbon dioxide, from the blood and channels it outside the body
Respiratory system
When you inhale through the nose, air enters the body and flows through a series of chambers and tubes, known as the ____________
- It includes the nasal cavity, pharynx, and larynx
Upper respiratory tract
The lower portion of the respiratory system, known as ________________, consists of the trachea in the neck and chest; the bronchial tree, which branches extensively throughout the lungs; the tiny air sacs within the lungs known as alveoli; and the lungs themselves
Lower respiratory tract
_______________ exchange occurs within the lungs across the walls of alveoli and adjacent capillaries and begins when air enters your alveoli during inhalation
-The oxygen in the air diffuses from the _________ into the capillaries to enter the bloodstream
-Carbon dioxide diffuses in the opposite direction (___________________), enabling you to remove the carbon dioxide from your blood with exhalation
Gas exchange
Alveoli
From capillaries to alveoli
Functions of the respiratory system
-Provides a stream of oxygen into the blood through the process of inhalation, followed by diffusion
-Removes carbon dioxide from the blood through the process of diffusion, followed by exhalation
The most common symptoms of respiratory disease are
Breathing problems
