Yes, they do. They have a type of endorphin that is called leucine-enkephalin.
Tears may contain loose cells (which contain DNA), but it is mostly just water and dissolved salts.
Yes, tears can contain trace amounts of DNA shed from cells in the eye. However, the amount of DNA in tears is usually very small and may not be suitable for use in genetic testing like saliva or blood samples.
Yes, tears do contain lysozyme, an enzyme that helps protect against bacterial infections by breaking down the cell walls of certain bacteria.
Yes, human tears contain trace amounts of iron, along with various other minerals and compounds. The primary components of tears are water, electrolytes, proteins, and enzymes, but the presence of iron is relatively minimal. This iron is not typically in a form that is significant for nutritional purposes. Overall, while tears do contain iron, it is just one of many substances found in this biological fluid.
The pain-controlling chemicals in the body are called endorphins.
Tears contain an antibacterial substance :)
No

tears contain urine. 90% of tears are urine.The bladder.
Tears contain lysozyme, an enzyme that can help kill bacteria by breaking down their cell walls. Additionally, tears contain other antimicrobial proteins and antibodies that can help protect the eyes from infections.

Water and salt, so H2O and Na.
Tears contain antibiotic properties. This is mostly from the salt it contains and some other helpful chemicals.
Your tears contain the enzyme lysozyme. This enzyme acts by disrupting the cell-walls of gram-positive bacteria by digesting the peptidoglycan in them, thereby preventing infection. This enzyme is also found in your saliva and is an example of a non-specific immune response.
