The Circulatory System

Organs of the Circulatory System

The Circulatory System carries blood and dissolved substances to and from different places in the body.

Organs of the Circulatory System

Heart

Blood Vessels (Arteries, Veins, Capillaries)

Multiple Choice

How many chambers does your heart have?

• 1

• 2

• 3

• 4

Blood travels throughout the body using a network of blood vessels. There are 3 specific types of blood vessels: arteries, veins, and capillaries.

Heart

• pumps blood through the network of arteries and veins

• The arteries and veins are responsible for carrying the blood to and from the heart and the rest of the body

• CARDIAC = HEART

• CARDIOVASCULAR SYSTEM

• The heart is the main organ of the circulatory system

Multiple Choice

Which system is the heart also a part of?

• skeletal system

• muscular systems

• nervous system

• respiratory system

Multiple Choice

The heart has __ chambers

• 2

• 4

• 6

• 8

Arteries

Blood vessels that carry oxygenated blood from the heart to other parts of the body.

The largest artery in the human body is the aorta.

Arteries contain elastic fibers that allow it to stretch under increased pressure.

Arteries contain muscles that contract to push blood along.

Multiple Choice

We represent ARTERIES with colour...

• Blue

• Red

Open Ended

Why do you think arteries need to be able to stretch under pressure?

Multiple Choice

Which chamber of the heart is connected to the aorta?

• Right atrium

• Left artium

• Right ventricle

• Left ventricle

Veins

Veins carry blood back to the heart

Veins have valves that force blood to travel in only 1 direction.

Veins run parallel to arteries in the body.

When muscles contract to move the body, they also help the blood flow through veins (as they surround the vein).

Multiple Choice

• Lungs, blood, blood vessels

• Heart, Blood Vessels, and Blood

• Liver, kidneys, and stomach

Components of your blood

• Red blood cells (RBC)

• White blood cells ( WBC)

• Plasma

• Platelet

Components of the Blood

• Plasma- About 55% of our blood. It is the liquid part of blood. It is mostly water.

• Red blood cells- They are red because of the hemoglobin.

• White blood cells- larger than red blood cells, and they have a nucleus. WBC help to defend against bacteria and viruses that get into the body.

• Platelets - little fragments of cells. If a blood vessel gets damaged, the platelets help the blood to clot and seal the wound.

Multiple Choice
