Skin & appendages
Looks like
The hollow under the shoulder: hairy skin with apocrine sweat glands, over the axillary lymph nodes.
What it does
Its sweat, broken down by bacteria, gives body odour; the nodes beneath drain the arm and breast.
Keeping it well
Washing and dry clothing do more than any deodorant. A lump here lasting over three weeks needs a doctor.
