Key Concepts
Arteries
When blood leaves the heart, it travels through arteries.
The walls of arteries are generally very thick. In fact, artery
walls consist of three cell layers.
Capillaries
In the capillaries, materials are exchanged between the
blood and the body’s cells. Capillary walls are only one cell
thick.
Veins
After blood moves through capillaries, it enters larger blood
vessels called veins, which carry blood back to the heart.
The walls of veins, like those of arteries, have three layers,
with muscle in the middle layer.
Vocabulary
Atrium-upper chambers of the heart, receive blood that
comes into the heart.
Ventricle-lower chambers of the heart- pump blood out of
the heart
Artery- blood vessels that carry blood away from the heart
Vein- blood vessels that carry blood back to the heart
Capillary-tiny, narrow vessels (connected to arteries) that
carry blood away from the heart. They deliver/exchange
substances between the blood and the body cells, and then
the flow goes back to the veins
