Technological Institute of The Philippines: Hs Bio 002-General ... - Free Printable

Since the image you've uploaded is a worksheet titled "Blood Flow in the Heart" from the Technological Institute of the Philippines, and it contains an unlabeled diagram of the human heart with instructions to color, label, and trace blood flow, I can help you solve the task by providing a detailed explanation of how to complete it.

🔍 Step-by-Step Guide to Complete the Worksheet

#### ✔ 1. Label the Parts of the Heart

Here are the key structures of the heart that should be labeled on the diagram:

| Structure | Location / Description |
|---------|------------------------|
| Superior Vena Cava | Large vein bringing deoxygenated blood from the upper body to the right atrium |
| Inferior Vena Cava | Large vein bringing deoxygenated blood from the lower body to the right atrium |
| Right Atrium | Upper right chamber receiving deoxygenated blood |
| Right Ventricle | Lower right chamber pumping blood to the lungs |
| Pulmonary Arteries | Carry deoxygenated blood from the right ventricle to the lungs |
| Pulmonary Veins | Carry oxygenated blood from the lungs to the left atrium |
| Left Atrium | Upper left chamber receiving oxygenated blood from the lungs |
| Left Ventricle | Lower left chamber pumping oxygenated blood to the body |
| Aorta | Largest artery carrying oxygenated blood from the left ventricle to the body |
| Tricuspid Valve | Between right atrium and right ventricle (prevents backflow) |
| Pulmonary Valve | Between right ventricle and pulmonary arteries |
| Mitral (Bicuspid) Valve | Between left atrium and left ventricle |
| Aortic Valve | Between left ventricle and aorta |

> 📌 Tip: Use different colors for chambers:
> - Right side (deoxygenated blood): Blue
> - Left side (oxygenated blood): Red

#### ✔ 2. Trace the Blood Flow in the Heart

Follow this path and draw arrows or use colored lines to show the flow:

##### 💔 Deoxygenated Blood Path (Blue Line):
1. Superior & Inferior Vena Cava →
2. Right Atrium →
3. Tricuspid Valve →
4. Right Ventricle →
5. Pulmonary Valve →
6. Pulmonary Arteries →
7. Lungs (for gas exchange) →
8. Pulmonary Veins →
9. Left Atrium →
10. Mitral Valve →
11. Left Ventricle →
12. Aortic Valve →
13. Aorta →
14. Body Tissues →
15. Back to Vena Cava (cycle repeats)

##### ❤️ Oxygenated Blood Path (Red Line):
- Starts from Pulmonary Veins → Left Atrium → Left Ventricle → Aorta → Body

#### ✔ 3. Coloring Instructions

- Color the right side of the heart (atrium & ventricle) in blue (deoxygenated blood).
- Color the left side of the heart (atrium & ventricle) in red (oxygenated blood).
- Color pulmonary arteries in blue (they carry deoxygenated blood).
- Color pulmonary veins in red (they carry oxygenated blood).
- Color aorta and systemic arteries in red.
- Color vena cavae in blue.

> ⚠️ Note: Pulmonary arteries are exceptions — they carry *deoxy* blood but are called "arteries" because they carry blood *away* from the heart.

✔ Final Tips for Completing the Worksheet

- Use colored pencils or markers as instructed.
- Write labels clearly near each structure.
- Draw arrows showing direction of blood flow.
- Double-check: Oxygenated = red, Deoxygenated = blue.
- Make sure valves are labeled correctly.
