Since I can't directly edit or label the image, I’ll guide you step-by-step on how to complete the task based on the directions provided. You can then use this information to fill in the worksheet correctly.

Step 1: Identify and Label the Organs in the Circulatory System
In the drawing of the human body (on the right), you should label the following key organs and structures related to the circulatory system:
1.
Heart – Located in the center of the chest, between the lungs.
- *Label:* "Heart"
2.
Lungs – The two pink organs on either side of the heart.
- *Label:* "Lungs"
3.
Arteries – Red vessels carrying oxygen-rich blood away from the heart.
- *Label:* "Arteries" (e.g., near the aorta or major arteries)
4.
Veins – Blue vessels carrying oxygen-poor blood back to the heart.
- *Label:* "Veins" (e.g., near the vena cava or major veins)
> 💡 Tip: Use text boxes next to each organ or vessel in your digital tool (like Google Slides or PowerPoint) to add these labels.

Step 2: Function of the Circulatory System
Write
1–2 sentences in the top box titled *"Function of the Circulatory System"*:
> The circulatory system transports oxygen, nutrients, hormones, and waste products throughout the body. It helps maintain homeostasis by delivering oxygen from the lungs and nutrients from the digestive system to cells, while removing carbon dioxide and metabolic waste.

Step 3: How the Circulatory System Works
Write a
paragraph in the bottom box explaining the route a drop of blood takes. Here's a clear example:
> A drop of blood begins its journey in the body’s tissues, where it picks up carbon dioxide and waste products. It travels through veins back to the heart, entering the right atrium, then moving into the right ventricle. From there, it is pumped to the lungs via the pulmonary arteries to release carbon dioxide and pick up oxygen. Oxygen-rich blood returns to the heart through the pulmonary veins, entering the left atrium and then the left ventricle. The left ventricle pumps the oxygenated blood out through the aorta to the rest of the body via arteries. As it flows through capillaries in the tissues, it delivers oxygen and nutrients before returning as deoxygenated blood to the heart, completing the cycle.
