PATHOLOGY

Detailed explanation-1: -Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.

Detailed explanation-2: -The endocrine glands do not have duct, so they release these hormones directly into the blood. The hormones travel in the blood circulation to reach their target sites (cells, tissues or organs) they can also travel in the lymphatic system when they are destroyed in the liver and removed by the kidneys.

Detailed explanation-3: -Hormones are your body’s chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including: Growth and development.

Detailed explanation-4: -One of the key functions of blood is transport. Blood vessels are like networks of roads where deliveries and waste removal take place. Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed.
