Blood Vessels
Arteries carry blood in which direction?
Away from the heart
Which part of blood carries the oxygen?
Red blood cells
How many chambers does the heart have?
4
The portion of the circulatory system that loops through the lungs
Pulmonary circulation
Blood vessels with the thinnest walls
capillaries
Veins carry blood in which direction
back to the heart
Which part of blood is mostly water?
Plasma
Blood returns to the heart here
Atria
The portion of the circulatory system that loops through the body
Systemic circulation
These keep blood moving in one direction
Valves
What are the largest blood vessels
arteries
The type of blood cells responsible for fighting off infection and disease
white blood cells
Blood leaves the heart here
ventricles
The main function of the circulatory system
To carry blood around the body delivering oxygen and nutrients and removing carbon dioxide and other waste
What gas is picked up in the cells and carried out as waste?
carbon dioxide
What do veins have that the other vessels don't?
Valves
What is the molecule inside red blood cells that binds to oxygen and carbon dioxide
hemoglobin
Thick muscular portion that separates the two sides of the heart
Septum
In the pulmonary circulation, which blood vessel carries deoxygenated blood
pulmonary arteries
What gas is picked up in the lungs and then carried out to the body?
oxygen
What is the main function of capillaries?
This is the main site of gas and nutrient exchange
What in the blood forms clots?
Platelets
Which side of the heart has oxygenated blood?
Left side, these chambers carry the blood that came from the lungs.
In the systemic circulatory system which main blood vessel carries oxygenated blood away from the heart?
Aorta
Trace the path of blood through the heart starting with the chamber that receives blood from the body and ending when the blood goes back out to the body
Right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, back to the body
