·         Deoxygenated blood –dirty blood.

·         Oxygenated blood-rich blood.

·         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.
