Final answer:
Patients with Ehlers-Danlos Syndrome bleed easier due to the weakness of blood vessel walls. This is because the syndrome affects the connective tissues in the body, including the blood vessels, leading to their fragility and increased susceptibility to rupture.
Step-by-step explanation:
Patients with Ehlers-Danlos Syndrome bleed easier due to the weakness of blood vessel walls. The syndrome affects the connective tissues in the body, including the blood vessels, leading to their fragility and increased susceptibility to rupture. This can result in spontaneous bleeding and easy bruising even from minor trauma.
For example, in the case of EDS type IV, also known as vascular EDS, the collagen in the blood vessels is affected. Collagen is an essential component of blood vessel walls, providing strength and structure. When the blood vessel walls are weak, they are more prone to rupture, causing bleeding.
Therefore, the correct answer to the question is (c) Weakness of blood vessel walls.
