Write 3-4 paragraphs comparing and contrasting arteries and veins.
Levart [38]
I'm not going to fully write out <span>3-4 paragraphs but I will give you some information to start out with :) I greatly enjoy doing research and writing about the things I have learned. 

Arteries:
Arteries are </span>any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body. <span> Each artery is a muscular tube lined by smooth tissue and has three layers. These are the three layers and their purpose. 
*The i</span>ntima-T<span>he inner layer lined by a smooth tissue called endothelium
</span>*The media- A<span> layer of muscle that lets arteries handle the high pressures from the heart
*</span>The adventitia-Connective tissue anchoring arteries to nearby tissues


Veins<span> are </span>blood vessels<span> that carry </span>blood<span> toward the </span>heart<span>. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the </span>pulmonary<span> and </span>umbilical veins<span>, both of which carry oxygenated blood to the heart. In contrast to veins, </span>arteries<span> carry blood away from the heart.
</span>Veins are classified in a number of ways, including superficial vs. deep, pulmonary vs. systemic, and large vs. small.
<span>
*Superficial veins are those closer to the surface of the body, and have no corresponding arteries.
</span><span>*Deep veins are deeper in the body and have corresponding arteries.
</span><span>*Perforator veins drain from the superficial to the deep veins. These are usually referred to in the lower limbs and feet.
</span><span>*Communicating veins are veins that directly connect superficial veins to deep veins.
*P</span>ulmonary veins<span> are a set of veins that deliver oxygenated blood from the </span>lungs<span> to the heart.
*</span><span>Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.

I hoped this helped and gave you some useful information. Good luck, I hope you do well on your assignment :) ~Sadie
