Final answer:
Increased H+ or HCO3- loss, DKA, and lactic acidosis refer to 'metabolic acidosis,' a state of excessive acidity in the blood due to primary bicarbonate deficiency, affecting the pH balance.
Step-by-step explanation:
Increased H+ or HCO3- loss, DKA, lactic acidosis is also known as metabolic acidosis, a condition where the blood becomes too acidic (pH below 7.35) due to primary bicarbonate deficiency. This can happen due to various reasons, such as ineffective breathing, leading to a buildup of CO2 in the bloodstream, excessive production of acids like ketones in diabetic ketoacidosis (DKA), or excessive acidity from lactic acidosis. Various conditions can lead to the reduction in the level or function of buffers, such as severe diarrhea where too much bicarbonate is lost, or kidney failure, liver failure, heart failure, and other ailments, resulting in an accumulation of acids in the body fluids.
