The human body is made up of a variety of glands that secrete substances that play an important role. The cells of some glands (e.g., sweat glands) have little synthetic activity and secrete mostly water and electrolytes (ions) transferred from the blood. Endocrine glands lose the connection to their original epithelium and therefore lack ducts. As they mature, they lose their granules and become part of the stratum corneum. Glandular epithelium is the membranous tissue made up of cells that covers all the glands in the body. The endocrine glands, which are located on our bodies, are glands that produce hormones that control a wide range of bodily functions, including how we exercise and how our bodies develop into cells. Answer: Sometimes a portion of epithelial tissue Lesions in salivary glands and submandibular tissues are caused by a dense infiltrate of lymphocytes, eosinophils, mast cells, and plasma cells, as well as a plethora of blood vessels. The glandular epithelium is the main element of the secretory portion of glands, the portion which produces and secretes the secretory product. These cells secrete substances that are either released directly into the lumen of the gland (exocrine glands) or into the blood stream (endocrine glands). Meristematic tissues are of three types: (i) Apical Meristem: It is present at the growing tip of the stem and roots and increases the length. Example of the unicellular gland - goblet cell of the alimentary canal On organs' surfaces, epithelial tissue known as glandular epithelial cells are found. CD4 T cells and DCs are the most commonly found in mild lymphocytic lesions with little lymphocytic foci. Each one of these ducts is connected to another, eventually leading to the development of the endocrine and exocrine glands. Multicellular glands. A tissue is a cluster of cells, that are alike in configuration and work together to attain a specific function. What is meristematic tissue class 9 Ncert?
