44
Q

SKIN COLOR AND APPENDAGES

release chemical substances directly into the bloodstream or tissues of the body

Q

SKIN COLOR AND APPENDAGES

release chemical substances through docks, to outside the body, or onto another surface within the body

A

these ducts usually empty into a hair follicle or onto the skin surface. all over the body except the palms and soles of the feet

A

sebaceous glands

47
Q

SKIN COLOR AND APPENDAGES

lubricant that keeps the skin soft and moist and prevents the hair from becoming brittle. Contains chemicals that kill bacteria, so it is important in preventing bacterial infection of the skin.

A

sebum
