MT 30 – IJ (LEC) 4 years, 1 month agoWilliam Harvey and the discovery of the circulation of the blood
Harvey’s discovery of the circulation had its origins in his early medical studies at the University of Padua, when he was a student of the renowned anatomist Fabricius, who was particularly interested in vein valves. Harvey’s adherence to the new notion of “scientific method”…[Read more]

1. Salivary glands – These are lined by a simple cuboidal epithelium and are surrounded by myoepithelial cell bodies, and their processes typically are found along the basal surface of the duct. The important functions of the simple cuboidal epithelium are secretion and absorption.
-
2. Pharynx – The pharynx is composed of mucous membrane, submucosal connective tissue, glands, lymphoid tissue, muscle and an outermost adventitial coating. The pharynx chamber serves both respiratory and digestive functions. Thick fibers of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.
-
3. Esophagus – The esophageal lining is protected by a stratified squamous epithelium. Because this epithelium is normally not exposed to dryness or to abrasion, it is non-keratinized.Scattered submucosal mucous glands provide lubrication. A well-developed muscularis provides peristaltic propulsion of food.
-
4. Stomach – The stomach and intestines have a thin simple columnar epithelial layer for secretion and absorption. The submucosa is a thick layer of loose connective tissue that surrounds the mucosa. This layer also contains blood vessels, lymphatic vessels, and nerves. Glands may be embedded in this layer.
-
5. Small intestine – The small intestine follows the general structure of the digestive tract in that the wall has a mucosa with simple columnar epithelium, submucosa, smooth muscle with inner circular and outer longitudinal layers, and serosa.
-
6. Large intestine – The four (4) layers of the large intestine from the lumen outward are the mucosa, submucosa, muscular layer, and serosa. The muscular layer is made up of two (2) layers of smooth muscle, the inner, circular layer, and the outer, longitudinal layer. These layers contribute to the motility of the large intestine.
-
7. Rectum – It is lined with intestinal epithelium (simple columnar epithelium) and at the anal transitional zone, it is lined non-keratinized stratified squamous…
-
8. Liver – The liver has a thin capsule of dense connective tissue, and a visceral (inferior) layer of peritoneal mesothelium, and is divided into left and right…
-
9. Gallbladder – The gallbladder is primarily an absorptive epithelium that functions to concentrate sodium salts of bile acids by near-isotonic fluid absorption from the gallbladder lumen.
-
10. Pancreas – It is lined with simple cuboidal epithelium and its important functions are secretion and absorption.The remaining tissue of the pancreas consists of endocrine cells called islets of Langerhans. These clusters of cells look like grapes and produce hormones that regulate blood sugar and regulate pancreatic secretions.

Histology Art (MT 30 – J) 4 years, 1 month agoKidneys, ureters, the urinary bladder, and the urethra constitute the urinary system. Urine production, storage, and expulsion are its primary functions.-
Kidneys serve multiple purposes:
• Excretion – the discharge of water -soluble metabolic waste products and foreign compounds as urine
• Regulation – maintain an appropriate fluid volume and electrolyte concentrations in body fluids, normal blood pressure, and blood pH.
• Endocrine – hormone secretion
• Regulation of blood pressure by Renin
-
Ureter
The ureters are fibromuscular tubes that transport urine from the kidney to the bladder via peristalsis. As with the urinary bladder, it is lined with transitional epithelium (urothelium).
-
Urinary Bladder
The urinary bladder is a muscular sac that stores urine, enabling infrequent and voluntary urination. It has a thick layer of smooth muscle and is lined by transitional epithelium (urothelium)..
