PPT-Introduction Endocrine tissue is made up of cells that produce secretions which are poured

Endocrine cells lie in close apposition to blood capillaries or sinusoids Secretions of endocrine cells are called hormones Hormones travel through blood to target cells and influence their function. Dr. . Zahiri. Dr. Zahiri. The endocrine system includes a number of different cells, structures, and organs which are not necessarily related at the gross anatomical level. . 1. . Histologically the endocrine system includes all structures and organs that have endocrine secretory cells as the parenchymal tissue. . TISSUES, AND MICROSCOPY . Part 2. VIBS 289. Larry Johnson.

Sputum is a . secretion . produced in the lungs and the bronchi (tubes that carry the air to the lung). . This . mucus-like secretion may become infected, blood stained, or contains abnormal cells that may lead to diagnosis. Part A. Endocrine System: Overview. Endocrine system – the body’s second great controlling system which influences metabolic activities of cells by means of hormones . Endocrine glands – pituitary, thyroid, parathyroid, adrenal, pineal, and thymus . Grace . Metry. , Meg Phillips, Rachel . Forcillo. , and Anna . Nevison. Lymphatic System. The lymphatic system aids the immune system in removing and destroying waste, debris, dead blood cells, pathogens, toxins, and cancer cells. . System. Body Membranes and the Skin. Body Membranes: 2 Types. Functions (overall)—Predict first! Write down in your notes!. Cover body surfaces. Line body cavities. Form protective and lubricating sheets around organs. Hierarchy of the Body. Smallest unit = atom. . Grouped atoms = molecules. Multiple molecules = organelles. Organelles = system of cells. Cell cluster = tissues/organs. Organ systems = organism . Organ System. What is t. he. Endocrine System?. The Endocrine System. The . endocrine. system contains . glands. , which release . chemicals. that need to be distributed around the . body. . . Glands. are . organs. hormones: chemicals released into the bloodstream by endocrine glands. Pituitary gland: gland located in the brain that secretes human growth hormone and influences all other hormone-secreting glands (also known as the master gland). Glandular Specialized Epithelium. Specialized Epithelial Tissue are a class of epithelial tissues that have very specific and specialized functions and structures. This tissue is composed of cuboidal, columnar, ciliated columnar epithelial cells.. Dr. . Gary Mumaugh. Essentials of Endocrinology .
