From the Guidelines

To prepare for your midterm exam, focus on understanding the structural components and functional relationships within the three key competencies: The Blood, The Circulatory System, and The Lymphatic System. The study guide portion provides detailed information on blood components (erythrocytes, leukocytes, and thrombocytes), heart anatomy (chambers, valves, and vessels), circulatory pathways (systemic, pulmonary, hepatic portal, and cerebral), and lymphatic structures (nodes, thymus, and spleen) 1. Pay particular attention to the functional relationships, such as how heart sounds correspond to valve closures and how the EKG waves reflect specific cardiac electrical activities.

Key Concepts to Focus On

  • Blood components and their functions: erythrocytes (oxygen transport), leukocytes (immune response), and thrombocytes (blood clotting) 1
  • Heart anatomy and physiology: chambers, valves, vessels, and heart sounds 1
  • Circulatory pathways: systemic, pulmonary, hepatic portal, and cerebral circulation 1
  • Lymphatic system: nodes, thymus, spleen, and lymph circulation 1

Practice Tests and Educational Resources

The three practice tests offer a variety of question formats to test your knowledge comprehensively. The multiple-choice questions assess basic recall, while short answer questions evaluate your understanding of processes and relationships. The diagram interpretation questions develop your visual recognition skills, which are essential for identifying anatomical structures. Utilize the suggested educational materials, including diagrams of blood components, heart anatomy charts, microscopic images, and video explanations of each system 1. These visual aids will enhance your understanding of complex structures and processes that can be difficult to grasp from text alone.

Studying Tips

When studying, focus on connecting structure to function across all systems, as the exam appears to emphasize not just identification but also understanding how anatomical features support physiological processes. Practice measuring and interpreting clinical data like blood pressure, EKG readings, and pulse rates to prepare for the practical aspects of the exam 1. By following this study guide and practicing with the provided resources, you will be well-prepared for your midterm exam and develop a strong foundation in the key competencies of The Blood, The Circulatory System, and The Lymphatic System.

From the Research

Study Guide

  • Competency 1: The Blood
    • Red Blood Cells (Erythrocytes): transport oxygen and carbon dioxide, biconcave, no nucleus
    • White Blood Cells (Leukocytes): types include neutrophils, lymphocytes, monocytes, eosinophils, basophils, functions include immune response and fighting infection
    • Platelets (Thrombocytes): function in blood clotting, structure as cell fragments from megakaryocytes
  • Competency 2: The Circulatory System
    • Heart Structures: chambers (right atrium, right ventricle, left atrium, left ventricle), valves (tricuspid, pulmonary, mitral, aortic), major vessels (aorta, vena cava, pulmonary arteries, pulmonary veins)
    • Heart Sounds: S1 (closure of AV valves), S2 (closure of semilunar valves)
    • Arteries vs. Veins: arteries have thick walls and carry blood away from the heart, veins have thin walls and carry blood toward the heart
    • Types of Circulation: systemic, pulmonary, hepatic portal, cerebral
    • Fetal Circulation: unique structures include foramen ovale and ductus arteriosus, bypasses lungs and connects heart chambers directly
    • Blood Pressure Measurement: systolic (pressure during ventricular contraction), diastolic (pressure during ventricular relaxation)
    • EKG Components: P wave (atrial depolarization), QRS complex (ventricular depolarization), T wave (ventricular repolarization)
  • Competency 3: The Lymphatic System
    • Gross Structures: nodes (filter lymph), thymus (produces T-cells), spleen (filters blood and stores blood cells)
    • Microscopic Differentiation: spleen has white pulp (immune functions) and red pulp (filters blood)
    • Lymph Circulation: pathway includes lymph capillaries, vessels, nodes, and ducts, role includes returning excess fluid to bloodstream and removing waste

Practice Tests

  • Test 1: Multiple Choice
    1. What are the primary functions of red blood cells?
    2. Which heart chamber receives deoxygenated blood?
    3. Identify the main difference between arteries and veins.
    4. What structure in fetal circulation bypasses the lungs?
    5. What component of an EKG indicates ventricular depolarization?
  • Test 2: Short Answer
    1. Describe the process of lymph circulation.
    2. Explain the function of platelets in blood clotting.
    3. Differentiate between systolic and diastolic blood pressure.
    4. Identify and explain the function of the thymus in the lymphatic system.
    5. Describe the structure and function of the heart's tricuspid valve.
  • Test 3: Diagram Interpretation
    1. Label the major arteries and veins in a diagram of systemic circulation.
    2. Identify microscopic structures of the spleen in a photomicrograph.
    3. Label the components of the heart on a detailed diagram.
    4. Interpret an EKG chart, indicating P wave, QRS complex, and T wave.
    5. Identify the cellular components in a blood smear image.
