Tissue Level of Organization

____________ tissues function to support tissues and bind structures together

Connective

Connective tissue, although diverse, share the following basic components

Proteins Fibers, Ground substance, Cells

Characterize tight junctions

They attach epithelial cells to neighboring epithelial cells, They encircle epithelial cells near their apical surfaces, They seal off the intercellular spaces of epithelial cells

Where might you typically find simple squamous epithelium

air sacs (alveoli) of lungs lumen of blood vessels (endothelium)

Keratinized stratified squamous epithelial tissue is located

as the epidermis of the skin

a thin extracellular layer upon which an epithelial rests is called

basement membrane

The cutaneous membrane

contains keratinized stratified squamous epithelial tissue and is relatively dry compared to other membranes of the body.

Nervous

controls activities, processes information

Describe the locations of epithelial tissue

covers many organs, covers body surfaces, lines many organs, lines body cavities

Epithelial general function

covers surfaces and lines body cavities and organs

The simple squamous epithelium that lines blood and lympatic vessels is called a(n)

endothelium

Muscle

facilitates movement

Many areas of spongy bone contain __________ cells, which are responsible for producing blood cells.

hemopoietic

The study of tissues and their relationships within organs is called

histology

simple cuboidal

one layer of cells that are about as high as they are wide

simple squamous

one layer of flat, wide irregular shaped cells

simple columnar, ciliated

one layer of tall, narrow cells that can move objects along their apical surface

simple columnar, nonciliated

one layer of tall, narrow cells that often contain microvilli

Serous membranes are composed of two parts: a _______ blank layer that lines the body and a _______ layer that covers organs.

parietal visceral

Fibroblasts

produce fibers and ground substance

Connective general function

protects, binds together and supports organs

Which type of epithelium is one cell layer thick

simple

3 types of muscle tissue

skeletal, smooth, and cardiac

Adipocytes

store lipid reserves

Fixed Macrophages

these large cells phagoctize damaged cells and pathogens

____________ epithelial tissue lines the urinary bladder.

transistional
