The two main differences between arteries and veins are the direction of blood flow and the presence of valves. Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart. Veins have valves to prevent backflow of blood, whereas arteries do not have valves.

What are the 2 main differences between plastic things and iron?
One main difference is that plastic is a synthetic material made from polymers, while iron is a naturally occurring metal. Another main difference is that plastic is typically lighter and more flexible, whereas iron is heavier and more rigid.
What are the main factors responsible for the differences in the three states of matter?
The main factors responsible for the differences in the three states of matter (solid, liquid, gas) are the relative movement of the particles, the arrangement of the particles, and the strength of the intermolecular forces between particles. In solids, particles are tightly packed and vibrate in fixed positions, while in liquids, particles are close together but can move past one another. In gases, particles are far apart and move freely. Interactions between particles are strongest in solids and weakest in gases.
How many different types of winds are there?
There are generally five main types of winds: trade winds, westerlies, polar easterlies, tropical easterlies, and jet streams. These wind patterns are influenced by the Earth's rotation and temperature differences between regions.
Which property spells the differences between infa-red and ultra-violet radiation?
The main difference between infrared and ultraviolet radiation lies in their wavelengths. Infrared radiation has longer wavelengths than visible light, making it thermal radiation that we feel as heat. Ultraviolet radiation has shorter wavelengths than visible light and can cause sunburn and skin damage.
In what two things is convection caused?
Convection is caused by temperature differences within a fluid (liquid or gas) and the resulting movement of the fluid due to these temperature variations. The two main factors that drive convection are heat energy transfer and density differences in the fluid.
What are differerences between veins and arteries?
Structurally, veins and arteries are very similar. The main differences is that veins move blood towards the heart, whereas arteries move blood away from the heart.
What describes the main difference between veins and arteries in the circulatory system?
Arteries carry blood from the heart and veins carry blood to the heart.
What are two main sections of the heart?
veins and arteries
What are the three main veins for drawing blood in the arm?
Arteries, veins, & capillaries are the three main veins while drawing blood in arm
What are the main kinds of blood vessels annd what functions do they perform?
The main kind of blood vessels are Veins, Arteries, and Capillaries. Arteries carry oxygenated blood to other organs. Veins carry blood with carbon dioxide back to the heart. Capillaries connect Veins and Arteries and let oxygen out to the organs and carbon dioxide in to the veins.
What is the main difference in the amount of gasses in most arteries and veins?
Veins carry carbon Dioxide to the heart and arteries carry oxygen to the body.
What are the main kinds of blood vessels and what function do they perform?
The main kind of blood vessels are Veins,Arteries, and Capillaries. Arteries carry oxygenated blood to other organs. Veins carry blood with carbon dioxide back to the heart. Capillaries connect Veins and Arteries and let oxygen out to the organs and carbon dioxide in to the veins.

What are the 2 main developmental pathways for blood cells?
Arteries and veins.
What are the three major vessels of blood circulation?
The main organ would be the Heart. Other major organs are the veins and arteries. Lungs are also a part of the blood circulatory system.
