Quiz 1 Immune system Flashcards
Dendritic cells are antigens presenting cells (T or F)
Verdadero
Antigens plays an important role in the production of antibodies (T or F)
What is the primary function of antigen-presenting cells (APC´s) in the immune system?
To present antigens to T cells
What is the role of the atrioventricular (AV) node in the cardiac conduction system?
Delaying the impulse transmission tu the ventricles
What role does vascular dysfunction play in the pathophysiology of essential hypertension, and how does it contribute to elevated blood pressure levels?
Vascular dysfunction leads to increased peripheral vascular resistance
During which phase of the cardiac cycle does the ventricle contract, causing a rise in ventricular pressure and closure of the atrioventricular valves (mitral and tricuspid valves)?
Ventricular systole
Innate response is highly specific (T or F):
