CLOSED SYSTEM FOR FLOW OF BLOOD BLOOD CARRIED THROUGHOUT BODY IN VESSELS
BLOOD VESSELS MAIN TYPES OF BLOOD VESSELS –ARTERIES –CAPILLARIES –VEINS
ARTERIES CARRY BLOOD AWAY FROM HEART –AORTA LARGEST ARTERY IN BODY –ARTERIOLES SMALLES BRANCHES OF ARTERIES JOIN WITH CAPILLARIES
CAPILLARIES CONNECT ARTERIOLES WITH VENULES THIN WALLS –ONE LAYER OF CELLS
VEINS BLOOD VESSELS THAT CARRY BLOOD BACK TO THE HEART –VENULES SMALLEST BRANCHES OF VEINS CONNECT WITH CAPILLARIES VEINS ARE THINNER THAN ARTERIES –HAVE LESS MUSCLE TISSUE
BLOOD CALLED A TISSUE –BECAUSE IT CONTAINS MANY KINDS OF CELLS 4-6 QUARTS OF BLOOD IN THE AVERAGE ADULT BLOOD CIRCULATES THROUGHOUT BODY CONTINUALLY
TRANSPORTATION OXYGEN FROM LUNGS TO BODY CELLS CARBON DIOXIDE FROM BODY CELLS TO THE LUNGS NUTRIENTS FROM THE DIGESTIVE TRACT TO CELLS
TRANSPORTATION METABOLIC WASTE PRODUCTS FROM THE CELLS TO THE ORGANS OF EXCRETION HEAT PRODUCED BY VARIOUS BODY PARTS HORMONES PRODUCED BY ENDOCRINE GLANDS TO ORGANS IN THE BODY
PLASMA FLUID OR LIQUID PORTION OF BLOOD 90 % WATER
SUBSTANCES DISSOLVED OR SUSPENDED BLOOD PROTEINS –FIBRINOGEN –PROTHROMBIN NECESSARY FOR CLOTTING –NUTRIENTS CARBOHYDRATES AND PROTEINS –MINERAL SALTS CALCIUM & SODIUM
PLASMA GASES SUCH AS –CARBON DIOXIDE –OXYGEN METABOLIC AND WASTE PRODUCTS HORMONES ENZYMES
BLOOD CELLS SOLID ELEMENTS OF BLOOD THREE KINDS OF BLOOD CELLS –ERYTHROCYTES –LEUKOCYTES –THROMBOCYTES
ERTHROCYTES RBC PRODUCED IN RED BONE MARROW 4 1/2 - 5 MILLION ERYTHROCYTES PER CC MM CONTAINS COMPLEX PROTEIN CALLED HEMOGLOBIN –COMPOSED OF PROTEIN MOLECULE GLOBIN IRON COMPOUND –HEME
LEUKOCYTES WBC NORMAL COUNT IS THOUSAN LEUKOCYTES LEUKOCYTES CAN PASS THROUGH CAPILLARY WALLS AND ENTER BODY TISSUE MAIN FUNCTION –FIGHT INFECTION
PHAGOCYTOSIS PROCESS BY WHICH SOME LEUKOCYTES ENGULF –INGEST –DESTROY PATHOGENS OR GERMS
Thrombocytes Platelets fragments or pieces of cells contain enzyme that stops bleeding 250,000 to 400,000 per cubic millimeter of blood
BLOOD Blood is a Liquid Connective Tissue that constitutes the transport medium of the circulatory system. The Two main functions of blood are to transport.
The Circulatory System The Heart, Blood Vessels, Blood Types.
The Circulatory System. What is the purpose of the circulatory system?
You Gotta Have Heart The Circulatory System Engage Walt Disney’s Hemo the Magnificent Walt Disney’s Hemo the Magnificent Scene 3 – The Heart Scene.
3.4 – The Circulatory System Importance of Circulation (Internal Transport) carries oxygen and nutrients to the cells for cellular respiration carries.
BLOOD. Body contains 4-6 L Consists of – Water – Red Blood Cells – Plasma – White blood cells and platelets.
Your Circulatory System The circulatory system is the bodys transportation system. It allows the body to transport, or move, materials from one place to.

RED ALERT! The Circulatory System and the Blood. Blood Blood is a heterogeneous mixture. It is a COLLOID, and has four main components 1.Red corpuscles.
Chapter 19 Circulation. Circulatory System A closed system A closed system Consisting of Heart, Arteries, Veins, Capillaries, Blood & the Lymphatic system.
1.1 Understanding the importance of having a transport system in some multicellular organisms.
Blood Blood is made up of four components: Plasma Red blood cells White blood cells platelets.
BLOOD VESSELS By: Ms. Reis. Blood Vessels 3 types of blood vessels form a network of tubes throughout the body to transport the blood. 1. Arteries 2.
