C _ _ o _ d _ l -

_________ layer of square or round cells. Makes glands: liver, salivary, etc.


Simple Cuboidal

Single

100

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

200

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

200
Having a great number of cells with very little extracellular matrix needed can be described as

Cellularity

200

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

200

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

300

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

300

Like most dense connective tissue, this tissue is avascular.

Cartilage

300

Connective tissues typically protect other tissues, which connective tissue type defies this?

Blood

400

_ _ e u _ _ s t _ _ t _ f i _ _ -

Secretion of mucus protects lungs from chemical and physical damage and microorganisms

Pseudostratified columnar epithelium

400

Epithelium needs support to maintain functionality. This support comes from another tissue type. This can be described as

Support by connective tissues

400

What gives connective tissue structure and function?

Connective Tissue Fibers and Ground Substance (more specific answers possible)

400

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.

500

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

500

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.

500

How do most dense connective tissues acquire nutrients and oxygen?

By diffusion, these are carried from nearby tissues to these tissues.

500

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
