Verified step by step guidance1
Understand the difference between exocrine and endocrine glands. Exocrine glands have ducts and release their secretions onto an epithelial surface, while endocrine glands lack ducts and release hormones directly into the bloodstream.
Identify the function of endocrine glands. They secrete hormones, which are chemical messengers that travel through the bloodstream to target organs or tissues.
Consider examples of endocrine glands, such as the pituitary gland, thyroid gland, and adrenal glands, which all release hormones directly into the blood.
Recognize that sweat glands and sebaceous glands are types of exocrine glands, as they release their products through ducts to the skin surface.
Conclude that the glands which lack ducts and secrete their products directly into the bloodstream are endocrine glands.
