Excretion GLOMERULAR FILTRATION ž This is the movement of fluid and solutes out of the glomerulus‚ across the glomerular capillary membrane‚ and into Bowman’s capsule. ž The filtrate that is formed here should NOT contain any red blood cells or protein. ž Filtrate contains mostly water‚ NaCl‚ K+‚ bicarbonate‚ glucose‚ amino acids‚ creatinine and urea GLOMERULAR

Erythema multiforme a self limited acute inflammatory disorder affecting skin‚muous membrane or both was first recognized by Bateman and Bulkley in 1817. In 1846‚ a first case was reported in America as “Herpes Iris.” Later‚ in 1866 Von Hebra‚ described the features under the term “erythema exsudativum multiforme” caused due to internal or systemic origin and not local in causation. According to him the patients with Erythema multiforme should have acrally distributed typical target lesions or raised

STRUCTURE OF NEPHRON: Nephrons (Greek nephros=kidney) are renal or kidney tubules. Each kidney has over one million nephrons that are responsible for removing waste products from blood and maintaining water‚ salt and pH balance in the body. This vital job results in the formation of urine. 1.Afferent Arteriole * receives blood rich in oxygen from the renal artery. * blood is transported to the glomerulus of the nephron where it is pressure filtered. 2.Glomerulus * The glomerulus

The Anatomical and Physical Features of Frogs Abstract: People have always wondered how frogs have the capability to live in both wet and dry environments. So why not dissect a frog to find out how. Frogs have both physical features like their skin that allows them to breath in water. They also have anatomical features like humans that allow them breath air just like us. Introduction As many people have learned throughout elementary and middle school amphibians are animals that have the

WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. The term anatomy refers to the structure and relationship of body parts such as tissues and organs. Physiology on the other hand is how these structures work as in individual and in the body as a whole. Take the circulatory system for example. The heart itself‚ blood vessels and blood

When the radius of the afferent arteriole was increased‚ the pressure and

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination
