Document Summary

Bee internal organs are similar to those of most insects and do same bodily functions as humans. Tubules pass waste to anterior intestine, and passes indigestible remains of food to rectum and out through anus. Lol the honeybees rectum can hold a lot, like a winters worth of waste at once. *bees do not store nutrients within their bodies, fat is important in wax secretion, in making eggs, and as stored energy. Circulatory system no real veins or arteries, just a single pulsing tube (heart) this is on top of abdomen. Glandular system= dispersed throughout the body: exocrine glands secrete outside the body and have functions: produce bees wax, and chemicals that signal to other bees, endocrine secretions (inside the body), regulate growth, dev, metabolism, water balance, activity. Mouthparts make tube for sucking up liquids/processing solid food. Complex pre-oral cavity receives food from food canal.
