Quick student answer

How do you explain (HT only) blood transports lactic acid from muscles to the liver?

Direct answer

In Biology, this page helps you answer questions about (HT only) blood transports lactic acid from muscles to the liver within Respiration. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are lactic acid and liver.

Key terms

  • lactic acid: A byproduct of anaerobic respiration in muscles, which can accumulate during intense exercise.
  • liver: An organ that processes lactic acid transported from muscles, converting it back into glucose.

Common trap

Misunderstanding Lactic Acid Transport: Emphasize that lactic acid is transported by the blood from the muscles to the liver, where it is processed, and clarify the importance of this transport in managing oxygen debt.
