Pseudostratified Columnar Epithelium: What is the function?

- Mucus traps microbe particles. - Vas deferans transports to non-ciliated sperm out. - Secretionof nutrients for sperm - Absorption excess sperm and fluid

Simple Columnar Epithelium: What is the function and where is it located?

Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus (or reproductive cells) by ciliated action. Location: nonciliated type lines most of the digestive tract (stomach to anal canal), gallbladder and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes. Fallopian tubes (ciliated) secrete and move egg along the uterus Uterus (ciliated)- secrete and move nutrients.

Stratified Columnar Epithelium: What is the function and location?

Function: protection and secretion Location: rare in the body; small amounts in male urethra and in large ducts of some glands

Stratified Cuboidal Epithelium

Function: protection, secretion and absorption Location: Largest ducts of sweat glands, mammary glands, and salivary glands.

stratified squamous epithelium: What is the function and location?

Function: protects underlying tissues in areas subject to abrasion. Keratin: Strengthen's waterproof epithelial cells. Location: nonkeratinized type forms the moist lining of the esophagus, mouth, and vagina; keratinized type forms the epidermis of the skin, a dry membrane.

Simple Cuboidal Epithelium: Function and location?

Function: secretion, absorption, limited protection Location: Lining proteins of Kidney tubules (nephron). Secretory portions of small glands, ovary surface: ovalution and repair if for example an egg erputs.

Simple Cuboidal Epithelium: How many layers?

Structure: One layer-cube shaped cells.

Simple Epithlium: What is it?

one layer of cells. They are necessarily thin and fragile. They cannot provide much mechanical protection, so simple epithelia are located only in protected areas INSIDE THE BODY. They line internal compartments and passageways, including the ventral body cavities, the heart chambers, and blood vessels.

Tranitional Epithelium: what is it and is it stratified epithelium or not?

Associated with the urinary system, stratified epithelium, tissues look different stretched vs relaxed.

Stratified Sqaumous Epithlium: How many layers?

Has mulitple layers of cells

Stratified Columnar Epithelium: How many layers?

Has two plus layers= columnar shaped

stratified cuboidal epithelium: How many layers and is it the rarest type of tissue in the body?

Has two plus more layers. It is the rarest type of tissue in the body,

Simple Squamous Epithelium: what is the location and function?

Location: Alveoli of lungs & blood vessels, lymphatic vessels. Renel corpuscles (nephron-tubes) of kidneys substances removed from blood-urine. Function:Absorption, diffusion, secretion, Mesothelium- produces serious fluid-reduce friction. Physcial integrity/wall of light packed cells provides protection

Simple Columnar Epithelium: How many layers?

Made up of a single layer of tall cells that fit closely together

Stratified Epithelium: How many layers and what is the functions?

Multiples tiers of cells. Functions: regenerate from below, lowest most layer of cells contains stem cells- divides to create new epithelial cells, provides protection!!

Pseudostratified Columnar Epithelium: How many layers?

One layer but looks like more than one of columnar shaped cells.

Simple Squamous Epithelium: How many layers and what is formed?

Single layer of flattened cells; Forms walls of capillaries & air sacs of lungs;
