Circulatory & Resp.

Circulatory & Respiratory Systems

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
