Verified step by step guidance

Understand the term 'hematoma': A hematoma is a localized collection of blood outside the blood vessels, usually caused by trauma or injury that damages blood vessels.

Identify the key physiological process: When blood vessels are damaged, blood leaks into the surrounding tissues, leading to the formation of a hematoma. This is a result of the disruption of the vascular integrity.

Eliminate incorrect options: Melanin production increasing in the skin is related to pigmentation, not hematoma formation. Epidermal cells undergoing rapid mitosis is associated with skin regeneration, not blood leakage. Sebaceous glands becoming blocked leads to acne, not hematoma.

Focus on the correct answer: The correct physiological explanation is that a hematoma develops when blood vessels are damaged and blood leaks into surrounding tissues, causing swelling and discoloration.

Relate to anatomy: Blood vessels are part of the circulatory system, and their damage can occur in various tissues, including skin, muscles, or organs, depending on the location of the trauma.
