Explanation:
The central lumens of thyroid follicles are filled with colloid, which consists of the protein thyroglobulin, a molecule that binds and stores thyroid hormone.
Thyroglobulin is a protein produced primarily by the thryroid gland. The thyroid gland is mainly made up of tiny, round shaped structures called follicles that produce and store thyroglobulin. Thyroglobulin acts as a substrate for the synthesis of the hormones (thyroxine and triiodothyronine) and also the storage of the inactive forms of thyroid hormone and iodine. Thyroxine and triiodothyronine assist in the regulation of the utilization of energy by the body.
Answer:
The exchange of substances between the blood vessels and the surrounding tissues can only happen in the <u>capillaries</u>.
Explanation:
Capillaries are the exchange vessels of our body. They form a network-like structure, called the capillary area. When blood, from the larger arterioles, spreads through the many capillaries in the capillary area, the blood pressure drops and the blood flows only at a slow speed. Through the thin, semi-permeable walls of the capillaries, the exchange of gas and substances between the blood and the surrounding tissue then takes place. Subsequently, blood continues to flow through the postcapillary venules, to which the capillary area has been reconnected. Blood pressure and blood flow increase and blood eventually reaches the heart through enlarged veins.
