Which component of blood is primarily responsible for oxygen transport?

A. Producing red blood cells: Red blood cells are produced in the bone marrow, not the lymphatic system, which focuses on fluid balance and immunity.

B. Transporting oxygen to tissues: Oxygen transport is carried out by red blood cells in the circulatory system, not the lymphatic system.

C. Regulating body temperature: Thermoregulation is primarily controlled by the hypothalamus and blood flow adjustments, not the lymphatic system.

D. Absorbing dietary fats from the intestines: The lymphatic system absorbs fats and fat-soluble vitamins from the digestive tract via lacteals, transporting them to the bloodstream, which is a key function alongside immune defense.

A. Vitiligo: Vitiligo is characterized by depigmented patches of skin due to the loss of melanocytes. It is not associated with inflammation and does not indicate an active inflammatory response.

B. Pallor: Pallor refers to a pale skin color, often caused by anemia, shock, or decreased blood flow. While it reflects systemic changes, it is not a direct sign of localized inflammation.

C. Erythema: Erythema is redness of the skin caused by increased blood flow to affected areas. It is a hallmark sign of inflammation and indicates vasodilation and immune activity in response to injury or infection.

D. Xerosis: Xerosis refers to abnormally dry skin, which can cause itching and flaking. It does not indicate an inflammatory process but rather a barrier or moisture-related issue.
