Types of Blood Vessels

What is the function of capillaries?

• Transports deoxygenated blood

• Transport oxygenated blood

• Site for exchange of materials

What is the function of veins?

• Transport deoxygenated blood

• Transport oxygenated blood

• Site for exchange of materials

What is the function of arteries?

• Transport deoxygenated blood

• Transport oxygenated blood

• Site for exchange of materials

What are present in veins but absent in arteries?

• smooth elastic tissues

• muscular tissues

• valves

How are capillaries adapted for their function?

• Have partially permeable walls

• One-cell thick endothelium

• Presence of valves

• Large lumen

I have a large lumen, I have thin muscular walls, I pump blood towards the heart

• Artery
• Vein
• Capillary
• Arteriole

I have muscular walls, and a small lumen.  Pump blood away from the heart

• Artery
• Vein
• Capillary
• Arteriole

Why do arteries have thick wall?

• Arteries have thick walls to handle high blood pressure.
• Arteries have thick walls to prevent oxygen loss.
• Arteries have thick walls to allow for easy blood flow.

• Arteries are designed to store blood for later use.

What is the need of arteries to have thick blood vessel wall?

• Arteries need thick walls to handle high blood pressure and maintain blood flow.
• Arteries require thick walls to prevent blood from flowing backwards.
• Arteries need thick walls to store excess blood.
• Arteries have thick walls to allow for easy gas exchange.

A system of the body which pumps blood too and from the lungs to become oxygenated. 

• Systemic
• Pulmonary
