Beta cells
Insulin is made by beta cells clustered within pancreatic islets. It is released into the blood, where it helps coordinate how tissues use and store nutrients. Although the pancreas also supplies digestive enzymes, insulin follows a separate endocrine delivery route.
300
Babies have more separate skeletal pieces than adults, often described as about 300 bones compared with the usual adult count of 206. The newborn number is approximate because developing bone and cartilage are not always counted the same way.
1 cm
People are usually slightly taller after a night lying down because spinal discs regain fluid when unloaded. Around a centimeter is a useful rough illustration, not a fixed daily change for everyone.
