Arteries carry blood from the heart and veins carry blood to the heart.
In a frog's circulatory system, the connection between arteries and veins is made through small blood vessels called capillaries. These capillaries allow for the exchange of oxygen and nutrients between the arteries and veins.
Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
Efferent arteries take blood away from an organ and afferent arteries bring blood to an organ.

Closed circulatory systems have blood that does not flow in defined blood vessels. Examples are insects and how their organs are bathed continually in "blood". Open circulatory systems have blood that flows in vessels. Humans have this system as blood flows in veins, arteries and capillaries.

they carry deoxygenated blood
The circulatory system of the chimp and human is basically the same.
Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)
arteries are thicker then veins
circulatory pressure
There is a huge difference between hot and beautiful. Hot is a word that describes appearance whereas beautiful describes personality.
