The Cell/Tissues

Cytoplasm

Provide structural support, hold the cells together

cell’s space

Simple Squamous Epithelial

one layer + flat

Function: diffusion, filtration, thin barrier

Location: Lungs

Cytosol

Fluid inside cytoplasm, cell water

Nucleolus

makes ribosomes

Ribosome

Makes proteins

Rough ER

makes/processes proteins

attachment of ribosomes

Smooth ER

Makes lipids + detoxifies

Golgi Apparatus

Modifies, sorts and packages

Lysosome

Digests/breaks down materials

Peroxisome

Helps break down substances, cleaner

Centrosome

Organizes microtubules

Microfilaments

Shape + movement

Intermediate filaments

Structural support

Microtubules

Movement+ chromosome separation

Microvilli

Increase surface area, more absorption

Simple Cuboidal Epithelial

one layer + cube

Function: absorption + secretion

Location: Kidney tubules

Simple Columnar Epithelial

One layer + tall

Function: secretion + movement

Location: airways + uterine tubes

Pseudo-stratified Ciliated Columnar

one layer + tall

Function: moves mucus

Stratified Columnar Epithelial

Many layers + tall

Function: protection + secretion

Location: Large ducts of salivary glands

Transitional

Relaxed > more rounded

Stretched > flatter

Function: allows stretching

Location: urinary bladder, ureters

Areolar

loose + open space +messy

Function: protects + connects tissues

Adipose

Function: Stores fat/energy, insulates, cushions, protects

Reticular

Function: supportive framework for lymphatic organs

Locations: spleen, lymph nodes, red bone marrow

Dense Regular

parallel

Function: strong in one direction

Location: tendons = muscle > bone, ligaments = bone > bone

Dense irregular

thick fibers in many directions

Function: Handles stress

Location: Skin

Hyaline Cartilage

smooth

Function: support, reduces friction

Location: nose, trachea, ribs/ sternum, growth plates

Fibrocartilage

Shock absorber

Function: weight-bearing, resists compression

Location: intervertebral discs

Elastic Cartilage

Flexible

Function: maintains shape while bending/stretching

Location: ear

Blood

transport

Centrioles

Inside centrosomes

Come in pairs

Structure: spindle fibers
