2. Introduction
The Circulatory is one of the most important organ systems in your body.
The Circulatory system distributes nutrients throughout your body. The Circulatory system also transports oxygen to cells and removes waste products.
The Circulatory system contains your heart, red blood cells, arteries, and veins

3. The Heart The heart is one of the most important organs in the body.
The heart’s main function is to pump blood through out the body.
Without the heart we live.
The parts of the heart are the Vena Cava, Right Atrium, Valves, Right Ventricle, Pulmonary Artery, Pulmonary Veins, Left Ventricle, and the Left Atrium.

4. Blood
Red Blood cells are specialized cells that transport oxygen through the body. They don’t have a nucleus.
White Blood cells are specialized cells that fight infection. They do have a nucleus.
Platelets are cells that help stop bleeding. They don’t have a nucleus.
Plasma is the liquid part of your blood that carries nutrients to your cells and carries waste away
The way that blood travels is through the vena cava, right atrium, right ventricle, pulmonary artery, lungs, pulmonary veins, left atrium, left ventricle, aorta, organs in the body.

5. Arteries, Veins, And Capillaries
Veins are blood vessels that carry blood to the heart
Arteries are blood vessels that carry blood away from the heart
Capillaries are the smallest blood vessels. They are one cell thick. They connect veins and arteries.

6. How the Circulatory System works with the other systems
The Circulatory System depends on the Nervous System to give messages on where to send blood
The Digestive System breaks down food to allow the Circulatory System to absorb it.
Different Parts of the Excretory System cleans the blood within the Circulatory System

7. Disease Leukemia- is a cancer of the blood or bone marrow.
You get it from an large increase of defective white blood cells.
The symptoms of leukemia are fatigue, excessive bruising, abdominal pain, weight loss, weakness, enlargement of lymph nodes, spleen, or liver, and abnormal bleeding.
Bone marrow aspirations and blood tests are common ways of diagnosing leukemia
Leukemia can be treated by radiation therapy (few side affects), or by getting a bone marrow transplant (risky surgery, needs donor, and high death rate, only use in life threatening situations.)
Leukemia affects your bone marrow. The bone marrow spreads bad cells into the blood stream, then into the lymph nodes. This weakness the immune system.

8. Fun Facts
The left side of the heart contains oxygenated blood whereas the right side has de-oxygenated blood
One drop of blood has about 5 million red blood cells and 12 thousand white blood cells
The heartbeats about 30 million times in 365 days
The body of an adult contains 60,000 miles of blood vessels
Blood that is rich in oxygen is red; blood that is poor in oxygen is blue.
