What are phagocytic calls?
Cells that release histamine during the inflammatory response
Cells in the immune system with four-part receptors shaped like a Y
Cells in the immune system with two chains
Cells that eat pathogens and destroy them
The Correct Answer is D
A. Cells that release histamine during the inflammatory response: These are mast cells, not phagocytic cells.
B. Cells in the immune system with four-part receptors shaped like a Y: This describes antibodies, specifically immunoglobulins, not phagocytic cells.
C. Cells in the immune system with two chains:This could refer to certain immune cells like T-cell receptors, but it does not specifically describe phagocytic cells.
D. Cells that eat pathogens and destroy them: Phagocytic cells, such as macrophages and neutrophils, engulf and digest pathogens as part of the immune response.

Correct Answer is C
Explanation
A. Preventing the absorption of sodium and potassium: This statement is incorrect because the respiratory system does not affect the absorption of sodium and potassium; it primarily influences the levels of carbon dioxide (CO2) in the blood.
B. Blocking the arterial walls from absorbing electrolytes: The respiratory system does not block electrolyte absorption through arterial walls. This is not a mechanism involved in acid-base balance.
C. Increasing ventilation to drop the H+ ion level: The respiratory system compensates for acidosis by increasing ventilation, which helps to expel more CO2 from the lungs, reducing the concentration of H+ ions and thus decreasing acidity.
D. Regulating the excretion or reabsorption of H+ and HCO3: This is the role of the renal system, not the respiratory system. The kidneys regulate acid-base balance by excreting or reabsorbing H+ and HCO3.
