  5. Define Pathophysiology
    The study of the functioning of an organism in the presence of a disease
  6. Nearly all cells of higher organisms have 3 main components:
    • Cell membrane
    • Cytoplasm
    • Nucleus
  7. Nearly all cells of higher organisms have 3 main components excluding:
    • Mature red blood cells
    • Platelets
  8. Consists of fats and proteins; protects the nucleus & organelles
    Semipermeable cell covering through which exchanges take place between the interior of the cell and the external environment
    Cell membrane
  9. A spherical formation containing genetic material, which is responsible for the functioning of the cell and the transmission of hereditary characteristics
    Nucleus
  10. A gelatinous-type substance in which the nucleus and all the organelles are immersed
    Cytoplasm
  11. The adaptive process by which the body maintains internal balance
    Homeostasis
  12. How does the human body maintain homeostasis:
    By balancing what it takes in with what it puts out
  13. Water balance in the body is maintained through:
    • Thirst mechanism
    • Release of antidiuretic Hormone
    • (ADH / Vasopressin)
  14. Normal levels for serum sodium (Na) are:
    136 to 144 mEq/L (milliequivalents per liter)
  15. Fluid deficit caused by excess body water loss without proportionate sodium loss
    Hypernatremia
  16. Fluid deficit caused by excessive sodium loss with less water loss
    Hyponatremia
  17. Causes of Hypernatremia and Hyponatremia:
    • Excessive sweating
    • Vomiting
    • Diarrhea
    • Inap. IV fluid use
    • Nausea
    • Headache
    • Seizure 
    • coma
  18. The gap that lies between each neuron that permits a neuron to pass an electrical or chemical signal to another cell
    Synapse
  19. In response to shock or stress, sympathetic nervous system stimulation causes:
    A) Vasoconstriction
    B) Shunting of blood to the body's periphery
    C) slowing of the heart
    A) Vasoconstriction
    (this multiple choice question has been scrambled)
  20. In addition to facilitating the uptake of sugar into the cells, insulin is responsible for:
    a) the chemical conversion of glycogen to glucose
    b) the chemical conversion of glucose to glycogen
    b) the chemical conversion of glucose to glycogen
  21. A medication that possesses a positive chronotropic effect is one that:
    increases heart rate
  22. What measures the disease-causing ability of a microorganism?
    Virulence
  23. Acid-base disturbances are classified into what two general categories:
    metabolic and respiratory
  24. What measures the disease-causing ability of a microorganism?
    Virulence
  25. The three most common types of distributive shock
    • Anaphylactic
    • Septic
    • Neurogenic
  26. Define septic shock
    widespread infection (bacterial)
  27. Define Neurogenic shock
    Spinal cord injury
  28. Distributive shock occurs when:
    There is widespread dilation of the resistance vessels.
  29. Anaphylactic shock is characterized by
    • Wheezing
    • Urticaria (hives)
  30. Atrophy is a(n): 
    A) increase in cell size.  
    B) larger number of cells.  
    C) cellular adaptation.
    D) decrease in cell size.  
    D) decrease in cell size.
