Pre Session Assignment PSA 11 Name Complete the vocabulary matching sections and at least the first three objectives for each chapter Doing so will prepare you for recitations and for the quizzes You are highly encouraged to complete the rest of the objectives to keep you on track and so you can ask for clarification during recitation All answers can be found in the textbook even if a section has not yet been covered in lecture Please complete and turn in one hour before the designated weekly recitation time via canvas Chapter 44 Objectives Internal Transport B volume of blood pumped by left ventricle into the aorta in one minute G the fluid that circulates in an open circulatory system D the osmotic pressure exerted by materials dissolved in the plasma or interstitial fluid J the fluid compartment of blood N the period of time when the heart is contracting K the endothelial tissue valve located in the aorta and in the pulmonary trunk C one in which the blood vessels are closed and fluid enters the interstitium via changes in hydrostatic and colloidal pressures F the pump in a circulatory system L the fluid compartment of blood minus the clotting factors A blood vessel carrying blood back to the heart I one in which the blood vessels are open ended and fluid leaves to enter the interstitium P blood vessel carrying blood away from the heart H the pressure exerted by the blood against the vessel wall E the period of time when the heart is not contracting O the amount of blood pumped out of a ventricle with one contraction M a circular muscle regulating flow into or out of an opening A Artery B Cardiac Output C Closed Circulatory System D Colloidal Pressure E Diastole F Heart G Hemolymph H Hydrostatic Pressure I Open Circulatory System J Plasma K Semilunar Valve L Serum M Sphincter Muscle N Systole O Stroke Volume P Vein 1 Describe the vertebrate circulatory system name and describe the components of whole blood and compare and contrast the structure and function of red blood cells the different types of anemia and the white blood cells granular and granular web helpful 1 Whole Blood Cells 2 Red Blood Cells a Produced i In red bone marrow vertebrae ribs breastbone skull bones and long bones b Function i ii Oxygen transport carbon dioxide transport Produces large quantities of hemoglobin c Pathology i Too few anemia 1 Types of Anemia 1 Loss of blood from hemorrhage or internal bleeding 2 Decreased production of hemoglobin or red blood cells as in iron deficiency anemia or pernicious anemia which is caused by vitamin B12 deficiency ii Too many polycythemia 1 iii Red blood cell production is regulated by the hormone erythropoietin which the kidneys release in response to a decrease in oxygen 3 White Blood Cells a Granular Leukocytes i ii Large lobed nuclei and distinctive granules 3 Types 1 Neutrophils a Function i Phagocytosis b Pathology i Too many may be due to bacterial infection inflammation myelogenous leukemia 2 Eosinophils a Function i Play role in allergic responses release proteins that are toxic to parasitic worms release compounds important in immune responses b Pathology i Too many may result from allergic reaction parasitic infestation 3 Basophils a Function i May play role in prevention of inappropriate clotting release histamine which is important in inflammatory responses 2 Name and describe the location of the human heart the anterior and posterior surfaces of the heart external and internal heart structures and a description of their function drawing helpful 1 External Structures a Anterior surface i Right atrium 1 Receives blood low in oxygen from the body and then empties the blood into the right ventricle ii Right ventricle 1 2 A valve between each atrium and its ventricle that prevents backflow of blood The right AV valve is the tricuspid valve the left AV valve is the mitral valve Pumps blood low in oxygen to the lungs Left atrium iii 1 Receives blood full of oxygen from the lungs and then empties the blood into the left ventricle iv Left ventricle 1 Pumps blood full of oxygen out to the body b Posterior surface i Pericardium 1 A tough connective tissue sac encloses the heart ii Pulmonary veins 1 A vein carrying oxygenated blood from the lungs to the left atrium of the eat iii Aorta 1 The main artery of the body supplying oxygenated blood to the circulatory system 2 It passes over the heart from the left ventricle and runs down in front of the backbone 2 3 Diagram and label an ECG and describe the events associated with it 1 Atrial depolarization P wave 2 Time delay between atrial and ventricular activation PR segment 3 Ventricular Depolarization QRS complex 4 Interval between ventricular depolarization and repolarization ST segment 5 Ventricular Repolarization T wave 4 Compare and contrast transport processes in animals with no circulatory system an open circulatory system and a closed circulatory system including how the processes work the components of each and what they do and animal examples of each 3 5 Compare and contrast the different blood types and construct a table that describes the compatibility of blood types 6 Summarize the role of platelets and the sequence of events involved in blood clotting 7 Compare and contrast the structure and function of arteries veins and capillaries the different types of capillaries the control of blood flow through capillary beds and the movement of fluid out of and into a capillary bed this will include understanding hydrostatic and colloidal pressures 8 Compare and contrast heart structure and blood circulation in different vertebrate hearts 9 Compare and contrast circulation in the fetal and adult heart 10 Describe the structure of the heart muscle name the structures of the heart conductance system and describe their function 11 Construct a set of graphs that describe events that occur at a node in the conduction system and those that occur in the heart ventricular contractile fibers 12 Explain how nervous system innervation and circulatory system regulators affect heart rate 4 13 Describe stroke volume the cardiac cycle and factors influencing cardiac output 14 Define blood pressure identify factors that regulate blood pressure and their effect compare blood pressure in different vessels of the circulatory system and give examples of nervous and hormonal 5
