PPT-Blood Blood is a tissue composed of

Erythrocytes the red blood cells Leukocytes the white blood cells Thrombocytes the blood platelets All these are suspended in a fluid plasma Blood circulates in the vascular system and transports oxygen and absorbed. Connective Tissue. General Characteristics. Does have blood vessels- . variations in blood supply (ligaments and tendons don’t heal as fast because they are poorly vascularized). Cartilage is avascular –no blood supply- heals very slowly. Most . common. Well . supplied with blood. . . (tendons and ligaments) . Made . up of . many types of cells and . extracellular matrix. . Extracellular matrix. Produced by the connective tissue . cells. “River of life”. Transports everything that must be carried from one place to another within the body:. Nutrients. Wastes. Heat. Composition of Blood. Blood cells or formed elements:. Red blood cells – transports oxygen. Form metabolic and structural connections between other tissues… nutrition and support. Forms a protective sheath around organs and helps insulate the body…cushion. Acts as a reserve for energy…storage. Connective Tissue - Recall. Epithelial Tissue (yesterday’s material). Basement Membrane. Connective Tissue. Three common types of cells found in connective tissue matrix:. 1. . Mast cells . – prevent blood clots. General Characteristics. Does have blood vessels- . variations in blood supply (ligaments and tendons don’t heal as fast because they are poorly vascularized). Cartilage is avascular –no blood supply- heals very slowly. 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 Dr . Natalie Cook. Senior Clinical Lecturer in Experimental Cancer Medicine, University of Manchester. Honorary Consultant in Medical Oncology. Christie NHS Foundation Trust. Talk overview. Liquid biopsy technologies . Cells are arranged in tissues that perform specialized structural and functional roles. Four Major Types of Tissue:. Epithelial. Connective. Muscle. Nervous. Introduction. General Characteristics. Covers free body surfaces. Fluids of the Body . Cells of the body are serviced by 2 fluids. blood. composed of plasma and a variety of cells. transports nutrients and wastes. interstitial fluid. bathes the cells of the body. Nutrients and oxygen diffuse from the blood into the interstitial fluid & then into the cells. Part of ECF. Has two portions. Cellular components. Erythrocytes (Red blood corpuscles - RBC). Leukocytes (White blood corpuscles – WBC). Thrombocytes. (Platelets). Extracellular components. Water. A. Kidney- paired organs that form the urine. . B. Ureters- carry urine to bladder, one from each kidney.. C. Bladder- site where urine is collected and stored until urination. . Functions:. Support. The bones of the legs, pelvic girdle, and vertebral column support the weight of the erect body.. The mandible (jawbone) supports the teeth.. Other bones support various organs and tissues..
