Hi ;)

The ultimate source of heat in the process of global warming is  - greenhouse gases.

Also, fumes get into the atmosphere and as a result huge amounts of carbon dioxide and sulphur lead to heavy smog over cities .

I hope it helps ;)

greenhouse gases are gases in the atmosphere that absorbs and emits ratiation within the thermal infrared range

the glands which are associated with each description is given below:

pancreas - is an endocrine and exocrine gland that secretes juices with enzymes for digestion. salivary glands- with protection and digestion in the mouth. liver- secretes bile for digestion.   lachrymal glands - secrete tears to moisten eyes and protect them from particles and infection.   sweat gland -regulates water, salt, and temperature. oil glands - to form a protective barrier on the skin.   goblet cells - secrete mucus for protection.
