Using the process flowchart, label each component with a sequential reference number. 1  These reference numbers will be used throughout the FMEA process. 2  The marked-up flowchart will give you a powerful visual to refer to throughout the PFMEA.
Although vitamin D deficiency rickets is rare in the United States, children who are dark skinned and living in cloudy northern cities as well as children on restricted diets due to cultural or religious beliefs are more likely to develop this disorder.
Rickets is a skeletal disorder that results from a lack of vitamin D, calcium, or phosphate. These nutrients are important for the development of strong, healthy bones. People with rickets can have weak and soft bones, stunted growth, and, in severe cases, skeletal deformities. Vitamin D helps your body absorb calcium and phosphate from your intestines. You can get vitamin D from various food products, including milk, eggs, and fish.
