Document Summary

3-4) chemical level - simplest level atoms combine to form molecules, molecules associate in specific ways to form organelles (basic components of the microscopic cells). 4 basic tissue types in human body epithelium - covers the body surface and lines its cavities. Tissues group of similarly structured cells that perform similar functions. Polarity apical surfaces (possibly attached to lumen, have dense microvilli and cilia to increase their surface area) and basal surfaces (cells firmly attached to below) Basal lamina noncellular, underlying supportive sheet of glycoproteins. Types of epithelial cells simple squamous thin and permeable, filtration, diffusion (smallest, thinnest possible cell) - found in kidney and lungs simple cuboidal secretion and absorption, but allows movement. Also direction and movement - found in kidney tubules, glands simple columnar digestion and secretion (digestive tract). Contain all organelles pseudo stratified columnar a single layer, cilia and mucus secretion are local specializations (respiratory tract) transitional epithelia (not simple) lines the bladder (must stretch and fill).
