How Blood Travels Through the Body

Largest Artery in the body

Aorta

These vessels and the heart make up the ___________________

Circulatory System

Finally, they all join one large blood vessel that receives all blood from the lower part of the body. This blood vessel is called the_______________.

Inferior Vena Cava

Receives all blood from the lower part of the body

Inferior Vena Cava

Blood leaves the __________and goes to the Aorta

Left Ventricle

Now that the blood has given up its______________and _____________ it must return to the heart. It moves into a larger blood vessel. This blood vessel is called a _________________. This droplet joins other blood going back to the heart. The blood vessels become larger and larger.

Oxygen and Food, Vein

Blood from head and arms separate and enter here

Right Atrium

Collects blood from head and arms

Superior Vena Cava

A system of ____________ carries the blood through the body.

Blood Vessels

Carries blood through heart

Blood Vessels

From here, the blood travels in smaller and smaller arteries until it reaches the very end of the big toe. The blood vessel here is so small it cannot be seen by the naked eye. This tiny vessel is a ________________. At this point, the droplet nourishes the cells next to this tiny vessel and takes away the waste products.

Capillary

The blood vessel here is so small it cannot be seen by the naked eye. This tiny vessel is a ________________. At this point, the droplet nourishes the cells next to this tiny vessel and takes away the waste products.

Capillary

Another large blood vessel collects blood from the head and arms. This vessel is called the_____________ _____________ ______________ Both then separetly enter the _____________ ______________ of the heart.

Superior Vena Cava, Right Atrium

The blood returns to the heart and goes to which blood vessels?

The Veins

These vessels include ______________, ________________ and ______________.

veins, arteries, and capillaries

Let's follow that droplet of blood through the blood vessels. When it leaves the left____________ of the heart, it goes into the_____________. This vessel is the largest artery in the body. Soon after leaving the heart, this vessel branches, so the droplet could move into the smaller arteries leading the head or arm. Let's assume this droplet travels down toward the legs. This largest artery divides to carry blood to each leg. This droplet of blood goes into one of the branches.
