The organism not only damages the blood vessels by causing them to leak, but also causes clotting inside the vessels.
Capillaries.
Additional irregular heartbeats can occur as a result of this procedure, as can damage to the blood vessels that feed the heart.
blood clots don't "cause" anything. They can block the flow of blood in vessels. they can stop it from leaking out. Of course, if a particular organ needs blood, lack of blood can cause symptoms. But that isn't your question.
Ischemic strokes occur due to blood vessels becoming blocked while hemorrhagic strokes are the result of broken blood vessels in or near the brain.

Blood clots are created by a complex chemical reaction and are used by the body to repair damage to blood vessels. Clots can also occur due to lack of mobility and diseases that disrupt the clotting mechanism.
Some weakened blood vessels will swell or worse they can break. If the break happens in the brain a type of stroke can occur.

Microangiopathic changes refer to pathological changes that occur in small blood vessels, leading to vessel damage and dysfunction. This can include thickening of vessel walls, narrowing of the vessels, and formation of microthrombi. These changes can impair blood flow to tissues and organs, leading to various complications.
Redness is a vasodilatation of nearby undamaged blood vessels.
Bruising is typically caused by damage to blood vessels under the skin, leading to blood leaking out and forming a visible mark. This damage can result from injury, trauma, or certain medical conditions that affect blood clotting or vessel integrity. Aging and certain medications can also increase susceptibility to bruising.
Erections are not constant because the body has mechanisms that regulate blood flow to the penis. When you are not sexually aroused, blood flow to the penis is restricted by the contraction of blood vessels, preventing a continuous erection. Erections occur in response to sexual stimulation when these blood vessels relax, allowing increased blood flow to the penis.
