Uxe the outine of the human body from Activity 111 and diaw and acubtory system. Include: a) he heart b) the blood vessets farteries and veins)

1. **Start with the human body outline** Use the Activity 111 human body outline as your base. This outline provides the reference where all internal structures, such as the heart and the network of blood vessels, will be added. 2. **Locate and Draw the Heart** - Inside the thoracic region (chest), draw an approximately conical or pear‐shaped diagram representing the heart. - Label the heart as \( \text{Heart} \). - Optionally, indicate the four chambers: - \( \text{Left Atrium} \) - \( \text{Left Ventricle} \) - \( \text{Right Atrium} \) - \( \text{Right Ventricle} \) - You can separate the heart into two sides: - The left side handling oxygenated blood. - The right side handling deoxygenated blood. 3. **Draw the Main Blood Vessels** - **Arteries:** - Draw an arrow emerging from the left ventricle for the \( \text{Aorta} \), the largest artery. - Add other major arteries branching from the aorta to distribute oxygen-rich blood across the body. - Represent the arteries with thicker lines and label them as \( \text{Arteries} \) (or use the symbol \( A \)). - **Veins:** - Draw arrows returning to the heart from various parts of the body, representing the collection of deoxygenated blood. - The two main veins to label are: - The \( \text{Superior Vena Cava} \) (returning blood from the upper body). - The \( \text{Inferior Vena Cava} \) (returning blood from the lower body). - Represent the veins with slightly thinner or differently styled lines and label them as \( \text{Veins} \) (or use the symbol \( V \)). 4. **Indicate the Flow of Blood** - Use arrows to show the direction of blood flow: - From the heart out through the arteries (oxygenated blood). - From the body back to the heart through the veins (deoxygenated blood). - For clarity, you can mark the oxygenation status, for example, using \( O_2 \) for oxygen and \( CO_2 \) for carbon dioxide if desired. 5. **Detail Branching of Vessels** - From the main arteries, draw smaller branches reaching into different regions of the body (e.g., arms, legs, head). - Similarly, for the veins, draw converging smaller veins that combine to form the superior and inferior vena cavae. - This branching network gives an overview of the systemic circulation. 6. **Final Touches** - Review your diagram to ensure the heart is centrally located in the chest area with the arterial network radiating outwards and the venous network converging back. - Check all labels are clearly written. - Optionally, add a legend explaining any symbols or color codings used (for example, red for arteries and blue for veins). The final diagram shows a simplified representation of the circulatory system within the human body outline, highlighting the \( \text{Heart} \), \( \text{Arteries} \), and \( \text{Veins} \), and clearly indicates the direction of the blood flow through the body.
