Find the odd one among the following blood vessels w.r.t. the blood (deoxygenated or oxygenated ) which is carried by them?

Options

A. Pulmonary artery
B. Pulmonary vein
C. Coronary veins
D. Vena cava

Answer

To solve the question of identifying the odd one among the blood vessels based on the type of blood they carry (deoxygenated or oxygenated), follow these steps:

### Step 1: Identify the Blood Vessels
List the blood vessels given in the question. The options are:
1. Pulmonary artery
2. Pulmonary vein
3. Coronary vein
4. Venacava

### Step 2: Determine the Type of Blood Each Vessel Carries
Now, analyze each blood vessel to determine whether it carries deoxygenated or oxygenated blood:
- **Pulmonary artery**: Carries deoxygenated blood from the heart to the lungs.
- **Pulmonary vein**: Carries oxygenated blood from the lungs to the heart.
- **Coronary vein**: Carries deoxygenated blood from the heart muscle (myocardium) back to the heart.
- **Venacava**: Carries deoxygenated blood from the body back to the heart.

### Step 3: Compare the Blood Types
Now, summarize the findings:
- **Deoxygenated blood carriers**: Pulmonary artery, Coronary vein, Venacava.
- **Oxygenated blood carrier**: Pulmonary vein.

### Step 4: Identify the Odd One Out
From the analysis, it is clear that the **pulmonary vein** is the only vessel that carries oxygenated blood, while all the others carry deoxygenated blood.

### Conclusion
Thus, the odd one among the blood vessels with respect to the type of blood they carry is the **pulmonary vein**.
