What types of collagen make up 80-90% of the collagen in our body?

Type I, II, and III collagen account for 80-90% of the total collagen in the human body, and each type plays a crucial role in various tissues.

Type I collagen is the most abundant, providing structure and strength to bones, tendons, and skin. It's crucial for wound healing and the integrity of various connective tissues. Type II collagen is primarily found in cartilage, playing an essential role in maintaining cartilage structure and function, which is vital for joint health. Type III collagen is often found alongside Type I in tissues and is important for the elasticity of skin and the structural network of organs. This combination of collagen types contributes significantly to the overall resilience, flexibility, and durability of connective tissues throughout the body.

The other combinations mentioned do not include the correct prevalence of these types, thus, making the answer specific to the composition of collagen in human tissues.
