Verified step by step guidance

1. Understand the basic anatomy of mammary glands: Mammary glands are specialized organs in mammals responsible for milk production. They are present in both males and females, although they are more developed in females.
2. Identify the location of mammary glands: Mammary glands are located in the breast tissue, not in the abdominal cavity. This is a key point to eliminate incorrect options.
3. Recognize the nature of mammary glands: Mammary glands are indeed modified sweat glands. They evolved from sweat glands and have a similar structure, which is why this statement is correct.
4. Clarify the function of mammary glands: While mammary glands are involved in milk production, they do not produce hormones. Instead, they respond to hormonal signals, such as prolactin and oxytocin, which regulate milk production and ejection.
5. Evaluate each statement based on the above clarifications: By understanding the anatomy, location, nature, and function of mammary glands, you can determine that the correct statement is that mammary glands are modified sweat glands.
