Nothing says âWelcome to Hawaiiâ more than a lei, flowers strung in a colorful loop to be put over the head and placed on the shoulders. Materials most often used to create these beautiful fresh ânecklacesâ include Dendrobium Orchids, Tuberose, Ti Leaf, Kukui Nut and Awapuhi Ginger Blossoms.
Beta cells (Î²-cells). Beta cells are a type of cell in the pancreas located in the so-called islets of Langerhans. They make up 65-80% of the cells in the islets. The Islets diameter is about 50 to 300 micrometers. They are composed of several types of cells. At least 70 percent are beta cells, which are localized in the core of the islet.
The Islets of Langerhans. The Islets of Langerhans are commonly referred to as islets (pronounced EYE-lets). Islets actually are clusters of cells, with each islet containing 3,000 to 4,000 cells. Scientists estimate there are 1 million islets in a healthy, adult pancreas. They make up only 1 to 2 percent of the entire organ. Within each islet are several types of cells, which work together to regulate blood sugar. One cell type is the beta cell. Beta cells sense sugar in the blood and release the necessary amount of insulin to maintain normal blood sugar levels. The immune system mistakenly sees beta cells as potential danger and destroys them, causing type 1 diabetes.
