What are the two types of duct glands that extract materials from the blood?

1. Apocrine and Eccrine

2. Sudoriferous and Sebaceous

3. Sebaceous and Ceruminous

4. Endocrine and Exocrine

The correct answer is: Sudoriferous and Sebaceous

The correct answer focuses on the understanding that sudoriferous (sweat) glands and sebaceous (oil) glands are types of exocrine glands that extract materials from the blood. Sudoriferous glands help regulate body temperature and eliminate waste through sweat, which contains substances filtered from the blood, including water, salts, and urea. Sebaceous glands, on the other hand, secrete sebum, an oily substance that keeps the skin and hair moisturized and also involves some filtration of blood components. The relevance of the other options lies in the types of glands they represent. Apocrine and eccrine refer specifically to types of sudoriferous glands, with eccrine glands being widespread and primarily involved in thermoregulation, whereas apocrine glands are found in specific areas such as the armpits and groin, and are associated with scent. Ceruminous glands produce earwax and are a specialized form of sebaceous glands but are not broadly relevant to general extraction from the blood like sudoriferous and sebaceous glands. Endocrine glands, while crucial in hormone production and regulation, do not involve ducts and directly release hormones into the bloodstream instead of extracting materials from it. Thus, focusing on sudor
