The body's first line of defence against shifts in pH is its acid-base buffer systems.
What is acid-base buffer system?
- The proper balance between the acids and bases in the body's extracellular fluid is crucial for the normal physiology of the body and for cellular metabolism.
- The first lines of defence are immediate, consisting of the various chemical buffers which minimize pH changes that would otherwise occur in their absence.
- The pH of the intracellular fluid and the extracellular fluid need to be maintained at a constant level.
- Proteins are denatured i.e. their 3D structure is disrupted, causing enzymes and ion channels to malfunction.
- An acid–base imbalance is known as acidaemia when the pH is acidic and alkalaemia when the pH is alkaline.

Answer:
Art is any subjective representation of the world, according to the artist's gaze, who represents it according to his own perceptions, trying to give his representation an aesthetic sense. There are various forms of art, such as painting, music, photography, cinema, etc.
Two forms of art that surprise me because they are considered as such are photography and architecture. In photography, the artist does not create or represent a work, but simply captures a certain image that he has not modified; and architecture because the architect performs his work for a technical purpose, and only then for aesthetics.
