What Are The Differences Between Arteries And Veins
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). 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
Extent of disease: As dr. Isobe said, the main difference is size. The similarity though is that they are both a manifestation of the same disease process--venous insufficiency and venous hypertension affecting a different end organ. With varicose veins, the end organ is larger veins (>3 mm). For spider veins, the end organ is much smaller veins (< 1 mm). ...Read moreSee 1 more doctor answer

Yes: Yes, the coronaryveins are thin walled vessels like all veins. The arteries are thicker, muscular walled structures as the coronary arteries actively dilate and contract in response to cardiac demands and various signals. In many instances, the coronary venous structures travel right next to the arteries. ...Read moreSee 1 more doctor answer
Throbosis=clot: A thrombosis is a blood clot. The veins are redundant meaning that there are a lot of them draining a certain area. So a venous thrombosis is usually not really important except for discomfort as long as it is in the surface veins. One in the deep veins is a medical emergency. The arteries are less redundant and a clot in an artery can damage the area it supplies and can be very serious. ...Read moreSee 1 more doctor answer
Same thing: Generally these are two terms for the same phenomenon, build up of cholesterol and plaque in the arteries of the body. This is made worse by high cholesterol and smoking, can run in families and is also more common in diabetics and patients with hypertension exercise, good diet no smoking and control of blood pressure and diabetes are the keys to treatments ...Read more

Great question!: Thrombosis is the formation of clot. It is safe to say all clots start out as a thrombus, and if they stay put they are forever a thrombus. But if a clot were to break off and travel somewhere else that it normally has no business visiting - like the lungs, kidneys, brain, arms, or legs it is now an embolus! doctors are obliged to figure out where emboli originated as this can affect treatment! ...Read moreSee 2 more doctor answers
Different outcome: Arterial thrombosis occurs when there is stoppage of blood flow in an artery due to arteriosclerosis or embolus. The part that is fed by the artery is injured by the lack of blood supply. Venous thrombosis comes on after there is stagnant flow, injury to the vein lining, and abnormalities in blood components. There is local pain, but rarely tissue injury. ...Read moreSee 1 more doctor answer
Hemorrhoids: Both hemorrhoid veins and lower extremity veins work to carry blood from the tissues back toward the heart. Hemorrhoids and varicose veins happen due to malfunction of the blood flow toward the heart. Pooling of blood in the rectum/ pelvis causes blood congestion of the hemorrhoidal veins resulting in hemorrhoids. Pooling of blood in the limbs causes stagnation of blood and varicose veins. ...Read moreSee 3 more doctor answers
DVT and CVI: Symptoms of chronic venous insufficiency are 'chronic' and rarely of abrupt onset. Patients will report having longstanding symptoms of aching and pain, swelling and may have skin changes like venous eczema or brown discoloration. DVT can cause abrupt pain and swelling but has a variable presentation and the only way to exclude it is to get a Duplex venous scan. Seek a phlebologist or go to the ER ...Read moreSee 1 more doctor answer
Correct: aneurysm usually applies to arterial structures taking blood from heart to body while varicose is used to describe venous abnormalities in vessels returning blood to heart. Arteries tend to be thicker walled and more prone to cholesterol buildup as part of handling higher pressures ...Read more
Different causes: Arterial thrombosis is usually caused by clots either in the heart or in the arteries that lead from the heart to the brain, most often the carotid arteries. Venous thrombosis has nothing to due with atherosclerosis and is often due to inflammation in the sinuses or head and neck. May also be due to venous congestion. ...Read more
Good question: When blood supply is interrupted the segment tissue that receives blood will die scar tissue will fill the gap as seen in heart attach myocardial infraction. ( heart attack ) , in gangrene initial stages same tissue necrosis or death tissue occurs , then get infected as seen in lower extremities and bowel etc. ...Read more
Blood flow: inflammation is a normal response to an injury or infection, causing redness, soreness, warmth, and swelling. Now, gangrene is a condition wherein the blood supply to an area is inadequate, perhaps caused by severe inflammation, and the tissue actually dies, turning dark or black, and will not normalize. The tissue will slough or have to be excised. I hope this helps. Good luck. ...Read more
