Where are the main veins in your body?
Arteries (in red) are the blood vessels that deliver blood to the body. Veins (in blue) are the blood vessels that return blood to the heart. Deep veins, located in the center of the leg near the leg bones, are enclosed by muscle. The iliac, femoral, popliteal and tibial (calf) veins are the deep veins in the legs.
What are the symptoms of a blocked artery in your leg?
- Painful cramping in one or both of your hips, thighs or calf muscles after certain activities, such as walking or climbing stairs (claudication)
- Leg numbness or weakness.
- Coldness in your lower leg or foot, especially when compared with the other side.
- Sores on your toes, feet or legs that won’t heal.
Which is the smallest vein in human body?
The smallest veins in the body are called venules. They receive blood from the arteries via the arterioles and capillaries. The venules branch into larger veins which eventually carry the blood to the largest veins in the body, the vena cava.
Is the largest artery of the body?
Why is it that pressure in your arteries is higher than pressure in your veins?
Increased pressure in the veins does not decrease flow as it does in arteries, but actually increases flow. Since pressure in the veins is normally relatively low, for blood to flow back into the heart, the pressure in the atria during atrial diastole must be even lower.
Why is cutting an artery worse than a vein?
Veins are different than arteries. The arteries are the vessels that carry blood away from the heart; they are muscular, elastic tubes that transport blood under the pressure of the hearts pumping action. Because the arteries are absolutely related to the bodys pressure, their bleeding is extremely dangerous.
How do you know if its a vein or artery?
Arteries, which usually look red, carry blood away from the heart. Veins, which usually look blue, return blood to the heart. Don’t look for veins deep down because they can be found right on top. If the needle hurts when you inject, you may have hit an artery or nerve.
Which leg is your main artery in?

How do you hit a vein?
Before you inject medication into a vein, have the patient squeeze a stress ball or rapidly open and close their hand to make the vein easier to see. Clean the area with rubbing alcohol and wrap a tourniquet around the arm, then carefully insert the tip of the needle into the vein at a 45° angle.
What are the thinnest veins called?
Capillaries feed the heart: They are the tiniest vessels that bridge the smallest arteries to small veins called venules. From there, blood passes into veins that serve as tributaries to larger veins before entering the heart. Capillaries are the smallest, thinnest blood vessels in the whole body.
