Question
Answer
Heart   Causes blood to flow through the body by its pumping action  
🗑
Blood vessels   Tubes that carry blood throughout the entire body

Arteries   carry blood that has oxygen and nutrients to all the parts of the body  
🗑
Veins   carry waste products (for example carbon dioxide) from all the parts of the body back to the heart  
🗑
Capillaries   very small vessels where oxygen and nutrients leave the blood to go into the cells and carbon dioxide and other waste products enter the blood from the cells  
🗑
Blood   composed of red blood cells, white blood cells, platelets, and plasma that have different functions  
🗑
Nose   Collects air from the environment and moistens and heats the air before it enters the trachea  
🗑
Trachea   The windpipe; moves air from the nose to the lungs  
🗑
Bronchi   Tubes that move air from the trachea to the lungs; one bronchus leads to each lung; part of each bronchus is outside the lung and part is inside  
🗑
Lungs   The main organs where gases are exchanged between air and the blood  
🗑
Alveoli   tiny sacs where gas exchange takes place in lungs  
🗑
Diaphragm   The muscle that aids in the breathing process  
🗑
Main Function of the Circulatory System   to transport blood to all parts of the body so that gases, nutrients, and waste products are transported to and from the cells  
🗑
White blood cells   help to fight infection in the body  
🗑
Main Function of Respiratory System   provide gas exchange between the blood and the air  
🗑
When air is inhaled, the lungs remove some of the _______   oxygen  
🗑
_____ ______ is exhaled back into the environment   carbon dioxide  
🗑
Path of Deoxygenated blood   travels within veins from the body to the heart and then to the lungs to be oxygenated  
🗑
Path of Oxygenated blood   travels within arteries from lungs to the heart before being pumped back to body  
🗑
Path of Air through Respiratory System   nose, trachea, bronchi, lungs  
🗑
