Heart:  Provides the force to "push" the blood throughout the body.

Arteries:  Carry blood away from the heart to the rest of the body.

Veins:  Carry blood to the heart from the rest of the body.

Capillaries:  The smallest blood vessels. Connect veins and arteries.  Gas exchange takes place here.

In the lungs there are tiny air­sacs called alveoli.  The capillaries "hug" the alveoli.  The alveoli and capillaries allow what is called the gas exchange.  Oxygen is picked up to be delivered to the rest of the body and carbon dioxide is dropped off to be exhaled.

Veins and arteries The highway of the body

Veins Arteries

As the blood leaves the heart, either as it travels to

the lungs to pick up oxygen, or to the body to drop off

the oxygen, it travels through the arteries.

Artiers - Away

When the blood heads to the heart, it is traveling through

the veins.

Red blood cells are in charge of carrying nutrients and oxygen to the body.

Platelets' job is to clot your blood and form a scab when you cut yourself.

White blood cells help fight infections when you are sick.

AortaThere are four chambers in the heart: left atrium, right atrium, left ventricle and right ventricle.  The left and right atriums are on the top, and the left and right ventricles are located on the bottom of the heart.  

The heart acts as two pumps: the left pump and the right pump.  The blood enters the right atrium from the body, via a vein, and is in need of oxygen.  It travels through a valve down to the right ventricle.  The right ventricle pumps the blood through an artery to the lungs.  In the lungs, it picks up oxygen from the capillaries of the lungs.  It travels through a vein back to the heart into the left atrium.  From there, it goes through a valve, down to the left ventricle.  The left ventricle pumps the blood through an artery called the aorta back to the body to drop off the oxygen.

After that, it starts its cycle all over again!
