Hi! I am a red blood cell. My name is Dennis. I will be showing you around and explaining blood flow in the body.
These are all red blood cells. We all work together and transport oxygen to the lungs. We also remove carbon dioxide.
blood travels through the capillaries. Then the systemic veins transport the blood from the body tissue all the way into the right atrium in the heart.
The left atrium is one of the chambers in the heart. It is located on the left posterior side. It acts as a holding chamber for blood returning from the lungs to act as a pump to transport blood to other areas of the heart.
The lungs allow oxygen in the air to be taken into the body, while it also enables the body to be able to get rid of carbon dioxide.
The right atrium is in the upper right chamber of the heart. The right atrium receives and holds deoxygenated blood from the superior vena cava, inferior vena cava, anterior cardiac veins, and the coronary sinus. Then it gets sent to the right ventricle.
