The Circulatory System transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as (a)   that body cells produce.

Match the following components of the circulatory system with their correct function:

Fill in the blank: (a)   are blood vessels that carry blood to the heart.

Fill in the blank: (a)   are tiny blood vessels where the exchange of gases and nutrients occurs.

(a)   is the gas needed for respiration and is transported to the body’s cells.

The arrangement of the circulatory system means that oxygen-rich blood and oxygen-poor blood do not mix.

The inside of the heart is divided into two sections so that the two types of blood (oxygen-rich and oxygen-poor) are kept apart. Which side of the heart contains oxygen-poor blood?

What does the pericardium cover?

Which layer of the pericardium is the innermost and directly on the heart?
