Which integumentary structure is responsible for the sensation of touch and pressure?

A. Osteoarthritis:Osteoarthritis involves progressive wear and tear of articular cartilage, resulting in joint pain, stiffness, and decreased range of motion.
B. Bursitis:Bursitis is inflammation of a bursa (fluid-filled sac) causing localized pain and swelling but does not primarily involve cartilage degeneration.
C. Rheumatoid arthritis:Rheumatoid arthritis is an autoimmune inflammatory synovitis that can secondarily damage cartilage, but its hallmark is systemic synovial inflammation rather than primary degenerative cartilage loss.
D. Gout:Gout is characterized by deposition of monosodium urate crystals in joints causing acute inflammatory episodes and tophi, not primary degenerative cartilage wear.

A. Oxygen transport:Oxygen transport is performed by blood (hemoglobin in red blood cells) rather than the integumentary system.
B. Temperature regulation:The integumentary system helps regulate body temperature through sweat production and cutaneous blood flow adjustments.
C. Nutrient absorption:Nutrient absorption primarily occurs in the gastrointestinal tract, not the skin (with the exception of limited topical absorption).
D. Hormone secretion:The skin contributes to endocrine activity by synthesizing vitamin D precursors, but widespread hormone secretion is not its main function.
