3 kinds of blood vessels

Answer 1

There are 5 kinds of blood vessels.

Arteries are the blood vessels that take blood away from the heart.

Arterioles are the blood vessels that connect arteries and capllaries.

Capillaries are the blood vessels that connect arterioles and venules.

Venules are the blood vessels that connect capillaries and veins.

Veins are the blood vessels that take blood to the heart.

But mainly it is the capillaries veins and the arteries

Answer 2

ARTERIES

• Transport blood away from the heart
• Do not contain valves
• Blood under high pressure and speed, blood pulses
• Structure = thick collagen (outer) and elastic fibre layers (middle), inner squamous epithelium layer

VEINS

• Transport blood towards the heart
• Contain semi-lunar valves to prevent backflow of blood

• Blood under low pressure, no pulse, blood moves (slowly) between valves with muscle contractions
• Structure = thin collagen (outer) and elastic fibre layers, inner squamous epithelium layer

CAPILLARIES

• Transport blood between tissues
• No valves
• Lower pressure than arteries, no pulse
• Movement of blood is slow to give maximum time for diffusion of substances

• Structure = single layer of squamous epithelium cells, no collagen or elastic fibres

Answer 3

Arteries carry oxygenated blood away from the heart to the body, veins return deoxygenated blood back to the heart, and capillaries connect arteries and veins, facilitating the exchange of nutrients and waste products between blood and tissues.
