Explanation:

Exocrine glands have ducts to secrete substances (like mucus by goblet cells, saliva by salivary glands, sweat by sweat glands, oil by oil glands, bile by liver, digestive enzymes by pancreas, tears by lacrimal glands) onto body surfaces or into body cavities. Endocrine glands secrete hormones directly into the bloodstream. The respiratory system is for gas exchange. The immune system is for defense against pathogens.
