URINARY DISORDERS. CHEMICAL CONTROL OF URINARY SYSTEM. Reabsorption of H2O in distal convoluted tubule controlled by ADH (antidiuretic hormone) – hormone makes collecting tubules more permeable to water ADH known as the “water-retaining hormone”By pandora-case
4.01 Remember the structures of the urinary system. 4.01 Remember the structures of the urinary system Essential Question. What are the structures of the urinary system?. Functions of the Urinary System. Excretion- removing nitrogenous wastes, certain salts and excess water from blood.By lizotte
URINARY SYSTEM CHAPTER 7. WASTE PRODUCTS. Sugar and fats combined with oxygen (in the cells to produce energy) = carbon dioxide and water (as waste products). Proteins combined with oxygen = nitrogenous wastes. ENERGY. SUGAR +. CO2. +. H2O. FAT +. OXYGEN. WASTE PRODUCTS.By shoskins

Blood Vessels Anatomy: 3 layers Tunica externa ( adventitia ) : outer layer; dense to loose connective tissue lotsa collagen, bits of elastin, few smooth muscles (veins) Tunica media : middle layer; concentric rings of smooth muscle within CT framework
Blood Vessels. Blood is carried in a closed system of vessels that begins and ends at the heart The three major types of vessels are arteries, capillaries, and veins Arteries carry blood away from the heart, veins carry blood toward the heart
Blood Vessels. Blood Vessels. Arteries, Veins and Capillaries. Arteries. Carry blood away from the heart Distribute nutrients Under high pressure Structure Tunica Intima : inner layer Tunica Media : thick layer of smooth muscle for blood pressure regulation
Blood Vessels. P A R T A. Blood vessels and circulation. Blood is carried in a closed system of vessels that begins and ends at the heart 5 types of blood vessels Arteries – carries blood away from the heart Arterioles – smallest arteries Capillaries - place for diffusion
BLOOD VESSELS. Blood Vessels : arteries, veins, capillaries ARTERIES : strong elastic vessels which carry blood moving away from the heart. Smallest ones are arterioles which connect to capillaries . VEINS - Thinner, less muscular vessels carrying blood toward the heart.
Blood Vessels. Chapter 19 – Day 1. Blood Vessel Structure. Fig. 19.1. Blood Vessels - Intro. Blood vessels are essentially a “pipeline” to: Carry blood TO parts of the body = arteries Carry blood BACK FROM parts of the body = veins Subdivisions
Blood Vessels. Blood is carried in a closed system of vessels that begins and ends at the heart In adult, blood vessels stretch 60,000 miles! The three major types of vessels are arteries, capillaries, and veins Arteries carry blood away from the heart (O2 rich, except pulmonary)
