Acid-Base Balance Quiz

What is the main purpose of acid-base balance in the body?

Which substance is primarily responsible for neutralizing excess acids in the body?

Which of the following conditions can disrupt the acid-base balance?

What is the primary mechanism the kidneys use to maintain acid-base balance?

Which blood pH range is typically considered normal for human physiology?

Acid-Base Balance Purpose

Maintains optimal pH levels in the body for proper enzymatic and metabolic functions.
Essential for physiological processes, including respiration and digestion.

Neutralizing Excess Acids

Bicarbonate (HCO3-) is the primary buffer that neutralizes excess acids.
It helps maintain pH by reacting with hydrogen ions (H+) to form carbonic acid.

Conditions Disrupting Acid-Base Balance

Respiratory disorders, such as chronic obstructive pulmonary disease (COPD), affect carbon dioxide levels.
Metabolic conditions, including diabetes or renal diseases, can alter bicarbonate and acid production.
Imbalances due to overproduction of acids (lactic acidosis) or loss of bicarbonates (diarrhea).

Kidney Mechanism for Acid-Base Balance

Kidneys regulate acid-base balance primarily through reabsorption and secretion of bicarbonate.
They also excrete hydrogen ions to maintain pH levels, ensuring homeostasis.

Normal Blood pH Range

The typical normal blood pH range is between 7.35 and 7.45.
Deviations from this range can indicate acidosis (below 7.35) or alkalosis (above 7.45).

Test your knowledge on the importance of acid-base balance in the human body. This quiz covers the mechanisms involved in maintaining acid-base equilibrium, the role of the kidneys, and factors that can disrupt this balance. Assess your understanding of normal blood pH levels and compensatory processes.
