Problem: Find a disease or homeostatic imbalance that affects histology, integumentary system, skeletal system, muscular system, cardiovascular system and lymphatic systems, respiratory system and digestive systems or urinary system and reproductive systems. Tell us what this disease does, how it is caused and what can be done to fix the disease. You then need to respond to a thread from another student regarding their post for the histology, integumentary system, or skeletal system homeostatic imbalance.
