### Direction of Blood Flow Inside the Heart #### Overview Understanding the direction of blood flow inside the heart is critical for comprehending how this vital organ functions in the human body. The heart consists of four main chambers, two atria and two ventricles, through which blood flows in a specific pattern. #### Diagram Explanation The provided diagram illustrates the direction of blood flow within the heart. The heart is sectioned into four chambers, depicted by different colors: blue for the right side and red for the left side. Let's break down each part of the diagram: 1. **Aorta**: Positioned at the top of the heart, the aorta is the main artery that carries oxygenated blood from the left ventricle to the rest of the body. 2. **Right Atrium (RA)**: This chamber receives deoxygenated blood from the body via the superior and inferior vena cavae. 3. **Right Ventricle (RV)**: After the right atrium, blood flows into the right ventricle, which then pumps it to the lungs through the pulmonary artery for oxygenation. 4. **Left Atrium (LA)**: Oxygenated blood from the lungs enters this chamber through the pulmonary veins. 5. **Left Ventricle (LV)**: Blood then moves from the left atrium to the left ventricle, which finally pumps it into the aorta to be distributed throughout the body. Arrows in the diagram show the direction of blood flow: - Blue arrows indicate the route of deoxygenated blood: entering the right atrium, moving to the right ventricle, and then being pumped to the lungs. - Red arrows represent the path of oxygenated blood: from the lungs to the left atrium, then to the left ventricle, and finally into the aorta for systemic circulation. #### Key Points - **RA (Right Atrium)**: Receives deoxygenated blood from the body. - **RV (Right Ventricle)**: Pumps deoxygenated blood to the lungs. - **LA (Left Atrium)**: Receives oxygenated blood from the lungs. - **LV (Left Ventricle)**: Pumps oxygenated blood to the body. #### Compass Directions A compass is included in the diagram indicating standard directions: - **S (Superior)** - **I (Inferior)** - **R (Right)** - **L (Left)** This directional guide helps orient the
