Difference between Arteries, Veins and Capillaries | Amphibians

The upcoming discussion will update you about the difference between arteries, veins and capillaries.

Difference # Arteries:

1. Tunica adventitia:

Moderately deve­loped

2. Tunica media:

Thick and well-developed.

3. Tunica interna:

Elastic fibres are pre­sent.

4. Elasticity:

Highly elastic.

5. Lumen:

Proportionately sma­ller in diameter.

Difference # Veins:

1. Tunica adventitia:

Thicker

2. Tunica media:

Thinner

3. Tunica interna:

Elastic fibres are absent.

4. Elasticity:

Non-elastic

5. Lumen:

Lager in diameter

Difference # Capillaries:

1. Tunica adventitia:

Absent

2. Tunica media:

Absent

3. Tunica interna:

This layers is only present and composed of endothelium. The elastic fibres are absent.

4. Elasticity:

Non-elastic

5. Lumen:

Small.
