Name one waste product transported by blood.

Answer

**Step-by-Step Solution:**

1. **Understanding Blood Composition**: Blood is a special type of connective tissue that consists of two main components: plasma and formed elements. Plasma makes up about 55% of blood, while formed elements (which include red blood cells, white blood cells, and platelets) make up about 45%.

2. **Identifying Waste Products**: The plasma in the blood is responsible for transporting various substances, including nutrients and waste products. Waste products are substances that the body needs to eliminate.

3. **Examples of Waste Products**: Common waste products transported by blood include carbon dioxide (CO2), urea, and lactic acid. These substances are byproducts of cellular metabolism and need to be removed from the body.

4. **Choosing One Waste Product**: Since the question asks for one waste product transported by blood, we can select carbon dioxide (CO2) as an example. It is a gas produced during cellular respiration and is transported from the tissues to the lungs for exhalation.

5. **Final Answer**: Therefore, one waste product transported by blood is carbon dioxide (CO2).
