Explanation Glands are defined as a group of specialized cells that is able to produce secretions. Exocrine glands and endocrine glands are two major types of glands. Endocrine glands mainly secrete hormones, and exocrine glands secrete enzymes. However, some glands have dual exocrine-endocrine functions such as the pancreas...

Question

Chapter 18, Problem 18.1.6AYLO

Summary Introduction

To determine:

The examples of the glands having dual exocrine and endocrine functions, and the secretory cells that cannot be categorized by simple endocrine-exocrine criteria.

Introduction:

Endocrine glands secrete hormones. They do not have ducts. They secrete hormones directly into the bloodstream and are then directed to organs and structures throughout the body. Exocrine glands produce chemical substances into ducts that are either directed to other organs or out of the body.

Students have asked these similar questions

Match the following to their proper description (answers may be used more than once). Exocrine glands Endocrine glands Goblet cells Goblet cells Merocrine secretion Holocrine secretion Apocrine secretion Endocrine glands Mucus Are unicellular glands. Have lost connection with the surface epithelium. Involves exocytosis of proteins or glycoproteins. Involves the discharge of secretory product with some cytoplasm and plasmalemma. Involves the disruption and shedding of the whole cell after being filled with secretory product. Is a hydrated form of the hydrophilic glycoproteins called mucins. Occur in the lining of the small intestine and the respiratory tract. Produce hormones. Retain connection with the surface epithelium.

How endocrine glands differ from exocrineglands

True or false: Pseudostratified epithelial tissue consists of many cell layers, therefore it is considered a stratified epithelium.
