Tissues bio 3

Simple squamous epithelium

Allows for diffusion and filtration within air sacs of lungs, lining of heart and vessels

Simple cuboidal epithelium

Absorption and secretion within kidney tubules and ovary surface

Nonciliated simple columnar epithelium

Containing microvilli and goblet cells that secrete mucus which helps in secretion, absorption and lubrication of stomach, and gallbladder

Ciliated pseudostratified columnar epithelium

Secretes mucus found lining most of the upper respiratory tract

Stratified squamous epithelium

Protects against abrasion, dehydration, and pathogens found in the epidermis (keratinized) and linings of the mouth, esophagus, and vagina (nonkeratinized)

Urothelium

Allows stretching while maintaining a protective barrier and is found lining the urinary bladder, ureters, and parts of the urethra

Acini (Pancreas)

darker purple cells that secrete pancreatic juices, found in pancreas

Salivary gland

produces saliva which aids in oral health and digestion, in the floor of the mouth

Sebaceous gland

Moistens hair, softens skin, and makes it waterproof, dermis, all over the body except palms and soles

Sudoriferous gland

release sweat for thermoregulation, located in the dermis on all parts of the body

Areolar connective tissue

strength and elasticity, subcutaneous layer and mucous membranes

Adipose connective tissue

reduces heat loss through skin and serves as an energy reserve, subcutaneous layer and kidneys

Reticular connective tissue

Forms the supportive framework of organs like the liver and spleen

Dense regular connective tissue

provides strong attachment between various structures, tendons and ligaments

Hyaline cartilage

Functions: provides smooth surfaces at joints for movement

Locations: at ends of long bones, and anterior ends of ribs

Bone tissue

protects organs and stores minerals, found in compact and spongy bone

Blood smear

RBC = transport oxygen and some carbon dioxide

WBC = carry on phagocytosis and mediate allergic reactions

within blood vessels and chambers of heart

Skeletal muscle

motion and heat production, attached to bones by tendons

Cardiac muscle

pumps blood to all parts of the body, heart wall

Smooth muscle

Moves substances and regulates blood flow through contractions, blood

vessels and intestines

Neuron

sendsa receives signals, brain and spinal cord

Neuroglia

Insulates axon for faster signals and supports neuron function

Islets (pancreas)

light purple cells that secrete hormones, found in pancreas
