Explanation:

Cartilage is a type of connective tissue that is characterized by being avascular and very flexible. There are three types of cartilages that can be differentiated by their histological properties, their function and their specific location in the body.

Hyaline cartilage is the most abundant and can be commonly found in articulations.

Fibrocartilage presents a mix of cartilage tissue and collagen fibers, making it tougher than the other types.

Elastic cartilage is much more flexible because it has elastic fibers and is found in places where this flexibility is needed (like the epiglottis).
