Where are capillaries found?

Muscle tissue
Bone marrow
Subcutaneous junction
Heart

The correct answer is: Subcutaneous junction

Capillaries are small, thin-walled blood vessels that are responsible for exchanging oxygen, nutrients and waste between the blood and tissues. They are found in most tissues and organs throughout the body. While capillaries can be found in muscle tissue, bone marrow, and the heart, they are most commonly found in the subcutaneous junction, which is the layer of tissue just beneath the surface of the skin. Capillaries are an important part of the circulatory system and their location in the subcutaneous junction helps with maintaining body temperature and proper blood flow. Therefore, the other options are incorrect because although capillaries can be found in those areas, they are not the most common location for them.
