Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Fluids are injected into the circulatory system through the veins and not arteries, why is this?

Fluids are injected into the circulatory system through the veins and not arteries, why is this?

Reasons: Veins flow toward the heart. IV medications are delivered to the heart and from there are rapidly dispersed throughout the body. Arteries travel away from the heart and toward the organs and extremities. A medication delivered into an arm artery would only travel to that hand. Also, arteries are much higher pressure vessels. There are more potential complications from puncturing an artery. ...Read more

Nicotine shuts down your circulation. Many with nicotine addiction like its calming effect, which long term leads to ischemic complications like stroke, heart attack, limb loss and sudden death. Hope you can quit. Small amounts red wine okay. ...Read more
