Epithelial
S _ m p l _
C _ _ o _ d _ l -
_________ layer of square or round cells. Makes glands: liver, salivary, etc.
Simple Cuboidal
Single
Having a Basal surface and Apical surface can be described as having
Polarity
T/F: Connective tissues are the most abundant and diverse tissues of the body
True
How would you describe the amount of cells typically found in connective tissue, to the amount of extracellular fluid.
There are typically few cells, and a great deal of ECF
S _ _ _ l e
_ _ u a _ _ u s -
_______ layer of thin cells. Found in air sacs (alveoli) of lungs and lining of intestines (other areas as well)
Simple Squamous
Single
Cellularity
Unlike most dense connective tissues, this tissue has many blood vessels and nerves
Bone
Has tunnels through the tissue called central canals to allow for blood vessels and nerves
If there is a strong concentration of electrolytes, amino acids (proteins), and carbohydrates connected to the cells of a tissue, would this attract or repel water?
Attract. Due to osmotic pressure, an area of high solute concentration attracts water molecules from an area of lower solute concentration.
C o _ _ m _ a _ -
________ layer of tall, narrow cells. Often contain a "brush boarder" of microvilli.
Simple Columnar
Single
With maintaining boundaries from cell to cell, now we connect cells to make tissue. We have ways to keep tissue sealed yet working as a unit. This can be described as
Sealed Cell Boundaries
Like most dense connective tissue, this tissue is avascular.
Cartilage
Connective tissues typically protect other tissues, which connective tissue type defies this?
Blood
_ _ e u _ _ s t _ _ t _ f i _ _ -
Secretion of mucus protects lungs from chemical and physical damage and microorganisms
Pseudostratified columnar epithelium
Epithelium needs support to maintain functionality. This support comes from another tissue type. This can be described as
Support by connective tissues
What gives connective tissue structure and function?
Connective Tissue Fibers and Ground Substance (more specific answers possible)
We typically describe tissues as a physical barrier, protecting or controlling the diffusion of substances. How does blood's function differ?
Blood acts as a "chemical connection". Meaning it controls the movement of heat, gases, nutrients, and other substances to areas where they are needed. It is a dynamic solution that changes greatly day to day.
U _ _ t h _ l _ _ m -
Allows urinary organs to stretch when they are filled with urine
Urothelium (also called transitional epithelium)
Special kind of stratified epithelium
Special to epithelium, we have two ways to name this tissue based on its physical characteristics. What are these naming differences?
Simple and Stratified. 1 layer vs multiple layers.
How do most dense connective tissues acquire nutrients and oxygen?
By diffusion, these are carried from nearby tissues to these tissues.
What functional differences are there between cilia and microvilli?
- microvillli and cilia increase surface area:volume ratio
- microvilli provide a greater SA to absorb substances- cilia provide a greater SA to increase movement of substances along the outer lining of a cavity
