Tiny sacs of tissue can refer to various structures in the body, such as alveoli in the lungs, which enable gas exchange, or vesicles in cells that transport substances. They are essential for various physiological functions, including nutrient absorption, waste removal, and cellular communication. These sacs often have specialized functions depending on their location and the tissue type they are part of.
The tiny sacs insure that the maximum area of tissue can be in close contact with the blood vessels to facilitate gas transfer
They are called Alveoli, look that up on wikipedia, or in your textbook.
