Final answer:
Churg-Strass syndrome involves inflammation of blood vessels, primarily arteries, veins, and capillaries. It primarily affects the respiratory system and can involve other organs as well.
Step-by-step explanation:
Churg-Strass syndrome, also known as eosinophilic granulomatosis with polyangiitis (EGPA), involves inflammation of blood vessels, specifically small- to medium-sized arteries and veins. This condition primarily affects the respiratory system, causing asthma, sinusitis, and lung damage. It can also involve other organs, such as the skin, heart, and nervous system. While lymphatic vessels are not typically involved in Churg-Strass syndrome, the disease primarily affects arteries, veins, and capillaries.
