Climate and Weather. Letâs be honest, few people come to Alaska for the weather. We are a land full of majestic mountains and waters populated by bears, whales, eagles, and heart-stopping scenery, but our weather, especially in Kodiak, can be challenging. The island, a rain forest, receives approximately 70 inches of rain and 70 inches of snow per year.
The pillar-like epithelial cells cover the finger-like projections (villi) of the intestinal surface. Observe the variation in appearance of the epithelial layer which is caused by different angles of cutting (refer to p. 6 of the lab manual).
The epithelium of the villi is made up of tall columnar absorptive cells called enterocytes, and goblet cells, which secrete mucin, for lubrication of the intestinal contents, and protection of the epithelium. This shows the epithelium of part of a villus at high magnification.his is a diagram which shows the villi of the small intestine, as indicated by the arrows in the diagram above, at higher magnification. The main functions of the small intestine are digestion, absorption of food and production of gastrointestinal hormones. The small intestine is 4-6 metres long in humans.
