Answer:
Artery : carries blood away from the heart, largest blood vessel in diameter
Vein : carries blood to the heart, has a thin endothelial layer.
capillary : exchanges nutrients with tissues, single walled.
Explanation:
Arteries are blood vessels that transport blood away from the heart to the body. They are the largest blood vessels in the body and have thick elastic walls.
Capillaries are blood vessels that carry blood away from body and exchange waste, nutrients, and oxygen with cells or tissues. Capillaries are smallest blood vessels and their walls contain only a single layer of tissues.
Veins are blood vessels that transport the blood from the body to the heart. Veins have less connective and smooth muscle tissue that make veins' walls thinner that walls of arteries.

Continuous conduction takes place in unmyelinated axon.
Explanation:
Based on the presence and absence of myelin sheath, the neurons had been classified as myelinated and non-myelinated neurons respectively.
In myelinated neurons the transmission of impulse takes place only at the non myelinated region called nodes of Ranvier. Due to this, the conduction in Myelinated neuron is saltatory.
The conduction in non-myelinated neuron takes place throughout the length of axon and it is continuous.
Saltatory conduction is faster than continuous conduction.
