vaskuliitti

Lokakuu 17, 2023

Vaskuliitti tarkoittaa tulehdus verisuonesta. Tulehdus vaurioittaa verisuonen seinämää, mikä estää veren normaalin virtaamisen sen läpi.

Miten vaskuliitti vahingoittaa verisuonia?

Blood vessels are hollow tubes that carry blood throughout the body. The open space in the center is called the lumen, and the vessel wall surrounds it. The tulehdus in vasculitis damages the blood vessel wall, which causes the lumen of the blood vessel to decrease in size. As a result, less blood is able to flow through the blood vessel. This may cause an injury called ischemia to the organs or tissues that normally receive blood from that vessel.

Minkä tyyppiset verisuonet vaikuttavat?

Blood vessels are found throughout the body, and they are divided into types depending on their size and whether they are delivering blood to the body or bringing it back to the heart. Blood leaves the heart through a large blood vessel called the aorta. The aorta connects with arteries and arterioles (small vessels similar to arteries) to deliver blood to the body. Veins and venules (small vessels similar to veins) bring blood back to the heart. Arterioles and venules are connected by small blood vessels called capillaries, which allow oxygen, carbon dioxide, nutrients, and waste to flow between tissues and blood. Any of these blood vessels may be affected by vasculitis.
