A
sweat pores
B
sebaceous glands
C
hair follicles
D
ear canal
Verified step by step guidance1
Understand the term 'cerumen': Cerumen, commonly known as earwax, is a substance produced by the ceruminous glands in the ear canal. It plays a protective role in maintaining ear health.
Identify the function of cerumen: Cerumen helps to lubricate and protect the ear canal by trapping dust, debris, and microorganisms, preventing them from reaching deeper parts of the ear.
Analyze the options provided: Sweat pores, sebaceous glands, and hair follicles are structures found in various parts of the body, but they are not directly related to the ear canal's lubrication.
Focus on the ear canal: The ear canal is the passageway that leads from the outer ear to the eardrum. Cerumen specifically lubricates this area to prevent dryness and irritation.
Conclude the correct answer: Based on the function of cerumen and its location, the correct answer is 'ear canal.'
