Facts we learned about the Cardiovascular System

• The heart has four chambers, the left and right atrium and the left and right ventricle.

• Deoxygenated blood –dirty blood.

• Oxygenated blood-rich blood.

• The left atrium receives oxygenated blood from the lungs through the pulmonary vein.

• The left atrium contracts causing the mitral valve to open sending the blood to the left ventricle.

• The left ventricle contracts sending the blood all over the body through the aorta.

• The aorta is the largest artery in our body.

• The Septum is a thick muscle that separates the right chamber from the left chamber.

• The right atrium receives deoxygenated blood from the body through the Superior and Inferior Vena Cava

• The right atrium contracts causing the tricuspid valve to open sending the blood to the right ventricle.

• The right ventricle contracts sending the blood to the lungs through the Pulmonary artery so you could exhale it.

• The dietitian informed us to eat fish because it has omega 3.

• Veins carry deoxygenated blood.

• Arteries carry oxygenated blood.

• The esophagus carries food.

• The windpipe/Trachea carries O2.

• The heart is the only muscle that never stops working.

• The different chambers work simultaneously in the heart.

• Fiber stops your arteries from clogging.

• Exercising brings up your HDL that burns your LDL.

• There are three different types of blood vessels, arteries, capillaries, and veins.

• We could have half a chocolate bar every day, and not on a daily basis.

• The left ventricle is the strongest chamber in your heart.

• Capillaries connect arteries and veins.

• Platelets clog your cuts so you don’t bleed to death.
