stroma

Stroma is the supportive tissue surrounding and anchoring organs or cells, providing structure and support. In biological contexts, such as in the lungs or the eye, the stroma refers to the connective tissue that helps maintain shape, supplies nutrients, and facilitates healing. In organs like the thyroid or skin, it consists of fibers, blood vessels, and other supporting cells. The stroma plays a vital role in maintaining the organ's health, facilitating communication between cells, and enabling repair when tissues are damaged.
