**DIAGRAM**: N/A
Description: A simplified diagram illustrating the human circulatory system, including the heart, lungs, and systemic circulation. The diagram uses color-coding to distinguish between oxygenated and deoxygenated blood, and arrows to indicate the direction of blood flow.
Components:
- **Heart**: Located centrally, depicted with both red (left side, oxygenated) and blue (right side, deoxygenated) sections.
- **Lungs**: Located at the top, connected to the heart by vessels. They are also depicted with red and blue sections, indicating gas exchange.
- **Systemic Circulation**: Represented by a large loop extending downwards from the heart to a stylized human figure (representing the body) and back to the heart. The vessels carrying blood from the heart to the body are red (oxygenated), and those returning from the body to the heart are blue (deoxygenated).
Blood Flow:
- **Pulmonary Circulation (Upper Loop)**: Deoxygenated blood (blue) flows from the right side of the heart to the lungs. In the lungs, it becomes oxygenated (red) and returns to the left side of the heart. This loop is associated with the top text box on the left.
- **Systemic Circulation (Lower Loop)**: Oxygenated blood (red) flows from the left side of the heart to the body. In the body, oxygen is delivered, and the blood becomes deoxygenated (blue), returning to the right side of the heart. This loop is associated with the bottom text box on the left.
Arrows clearly show the unidirectional flow of blood through both pulmonary and systemic circuits.

Data: N/A
Context: This diagram is used to identify and describe the two main types of blood circulation in the human body: pulmonary and systemic circulation, including their paths, goals, and potentially their discoverers.
