What type of epithelial tissue makes up the tube shown below?

Simple squamousStratified squamousSimple cuboidalStratified cuboidalSimple columnarPseudostratified columnar123456789101112131415161718192021222324252627282930This is a capillary made up of simple squamous epithelium. It allows diffusion to happen quickly so nutrients and wastes can be exchanged QUICKLY!!!!2

The yellow stuff is mucous which has been produced by a Goblet cell or underlying glandular epithelium.3

Where would you find this type of tissue?

HeartKidneyLungAnusSmall IntestineTracheaSkin123456789101112131415161718192021222324252627282930These are cross sections of simple cuboidal epithelium which make up kidney tubules. These cells allow excretion, secretion and some absorption.5What area is the line on?

The luminal surface of the tube.A glycoprotein layer that allows attachment of epithelial cells.A phospholipid bilayer called the basement membrane.A specialized area filled with cilia.The free surface123456789101112131415161718192021222324252627282930Basement membrane is not a membrane. It is made up of glycoproteins which provide attachment for epithelial tissues.6What best describes the tissue in the red circle below?

You can see some goblet cells too. This is a cross section of a small inestine. 7

This could either be kidney tubules or a duct of an exocrine gland.8What best describes the process that occurs between the balloon like structures filled with gas and the liquid filled tubes covering them?

It is made up of simple squamous epithelium. Also the capillary bed surrounding the alveoli is made up of simple squamous epithelium. These allow for diffusion of oxygen and carbon dioxide between the blood and outside environment. 9

EpithelialConnectiveMuscleNervous123456789101112131415161718192021222324252627282930Loose Irregular connective tissue is found underneath epithelial layers. This allows for attachment and a place for blood vessels. Epithelium is avascular and relies on diffusion from blood vessels down in the connective tissue to provide glucose, amino acids, oxygen and other needed nutrients.10

Which number represents a Goblet Cell?

These increase membrane surface area to provide more space for active transport proteins(absorption of monomers). Each monomer needs a specific transport protein and thus we need lots of membrane surface area. The goblet cell is important that it secretes mucous which protects the membrane from being broken down from lipases and proteases that are in the lumen of the small intestine from the pancreas.12Which arrow is representing the free surface?
