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 |
