As the Trusty Narrator mingles among the attendees, he encounters Mr. Armpit—a personified character representing the human armpit. Their interaction highlights the often-overlooked importance of armpits.

3. Armpit Functions and Sweat Production ([03:19] – [10:44])

The conversation delves into the biological functions of armpits, focusing on sweat production and the role of lymph nodes.

• Mr. Armpit:
  “One of my biggest functions is to be the home to more than 20 lymph nodes.” ([07:03])

He explains that lymph nodes are vital for transporting oxygen, hormones, nutrients, and removing metabolic waste from the body.

The discussion then transitions to sweat glands:

• Mr. Armpit:
  “The kind of odor you produce is dependent on many things... the yellowing is actually caused by a chemical reaction between your sweat and the aluminum in your deodorant.” ([10:44])

• Trusty Narrator:
  “I'm sure, you just sat in the seat reserved for Mr. Pitt.” ([02:05])

They distinguish between eccrine glands, which produce odorless sweat for temperature control, and apocrine glands, which emit thicker sweat that can lead to body odor when mixed with bacteria.
