Connective tissue flows through the heart and blood vessels.
The outer layer of blood vessels is composed of connective tissue called the tunica externa or adventitia. This layer provides structural support and protection to the blood vessel. It also helps to anchor the vessel in place within surrounding tissues.

blood vessels, lymphatic vessels, and connective tissue
Connective tissues vary in their vascularity, meaning some types have blood vessels while others do not. For instance, dense connective tissues like tendons and ligaments have a limited blood supply, while loose connective tissues, such as areolar tissue, are more vascularized. Cartilage, another type of connective tissue, is avascular, relying on diffusion for nutrient supply. Therefore, the presence of blood vessels in connective tissue depends on the specific type of tissue.
Nipples are composed of dense connective tissue and smooth muscle. They also contain nerve endings, blood vessels, and milk ducts.
