what is the difference between arterial ulcer and venous stasis ulcer?

Arterial ulcers develop as the result of damage to the arteries due to lack of blood flow to tissue. Venous ulcers develop from damage to the veins caused by an insufficient return of blood back to the heart. Unlike other ulcers, these leg wounds can take months to heal, if they heal at all.

Veins differ from arteries in structure and function. For example, arteries are more muscular than veins, veins are often closer to the skin, and veins contain valves to help keep blood flowing toward the heart, while arteries do not have valves and carry blood away from the heart.

Mouth ulcers are often painful whereas mouth cancer is not. Mouth ulcers will clear up in about 2 weeks, whereas mouth cancer will not go away and will often spread. Mouth cancer patches may be rough, hard, and not easy to scrape off.

Stomach ulcer Stomach ulcers, also known as peptic ulcers, are sores on your stomach lining that can cause a gnawing, burning sensation, usually felt in the upper abdomen. The pain can find its way up to the chest, Dr. Madanick says. The pain is often more dull and persistent than heartburn.

In arterial bleeding, the blood pumps or spurts from the wound with each heartbeat. In major venous bleeding, the blood just runs out of the wound at a steady rate. The arterial bleeding is bright red compared to the dark red of venous bleeding. Minor bleeding (from capillaries), however, can also be bright red.

Whereas arteries specifically carry blood “away” from the heart, veins carry blood “toward” the heart. Generally speaking, arterial vessels contain oxygenated blood, and venous vessels carry blood that is low in oxygen.

Veins are less flexible than arteries. They have valves (doors) that open and close to let blood through. ... The chief difference between arteries and veins is the job that they do. Arteries carry oxygenated blood away from the heart to the body, and veins carry oxygen-poor blood back from the body to the heart.

An erosion is different from an ulcer. An "ulcer" is an area of damage to the gastrointestinal wall (in this case the gastric wall) that extends deeper through the wall than an erosion (an ulcer can extend anywhere from beyond the lamina propria to right through the wall, potentially causing a perforation).

Folic acid plays a dual role in the healing of leg ulcers. It is an effective vasodilator for the microcirculation, and a contributor to adequate protein metabolism.

Arterial blood is the oxygenated blood in the circulatory system found in the pulmonary vein, the left chambers of the heart, and in the arteries. It is bright red in color, while venous blood is dark red in color (but looks purple through the translucent skin). It is the contralateral term to venous blood.

Name two structural differences between arteries and veins. Arteries have thick, elastic, muscular walls whereas veins have thin walls with few elastic fibres. Arteries need these properties to give them the strength and elasticity needed to cope with the high pressure surges of oxygenated blood coming from the heart.

Herpes ulcers are shallow, small and on the red base(surrounded by red skin). Painful in itself with possible painful lymphadenopathy Syphilis usually has solitary sore. Syphilis ulcer is usually deeper and larger Painless in itself with painless lymphadenopathy.

In GERD, acid in the esophagus is the problem, whereas with an ulcer, acid is causing a problem in the stom- ach lining. So, the medication used to treat them is the same, an acid reducer (e.g. Pepcid, Zantac and Prilosec).

Ulcers. A peptic ulcer is a sore on the lining of your stomach, small intestine or esophagus. A peptic ulcer in the stomach is called a gastric ulcer. A duodenal ulcer is a peptic ulcer that develops in the first part of the small intestine (duodenum). An esophageal ulcer occurs in the lower part of your esophagus.

To return blood to the heart, there is a series of venules, veins, and muscular veins. Venules have much larger lumina and thinner walls than corresponding arterioles. Similarly, the veins are distinguishable from arteries and arterioles, because their walls are much thinner, compared to the diameter of their lumen.
