Tissues Flashcards
What tissue comprises most of the kidney tubules and the bronchioles?
Simple Cuboidal Epithelium
What tissue comprises most glandular tissues?
Simple Cuboidal Epithelium
What are the functions of simple cuboidal epithelium?
-Absorption & Secretion
-Production of protective mucus coat
-Movement of respiratory mucus
What tissue comprises the air sacs (alveoli) of the lungs, glomerular capsules of the kidneys, and some kidney tubules?
Simple Squamous Epithelium
What tissue comprises the inner lining (endothelium) of the heart, blood vessels, and the surface mesothelium of pleura, pericardium, peritoneum, & mesenteries?
Simple Squamous Epithelium
What tissue comprises the serous membrane of the stomach, intestines, and some other viscera?
Simple Squamous Epithelium
What are the two functions of simple squamous epithelium?
-Rapid diffusion of substances through membrane
-Secretes lubricating serous fluid
What tissue comprises the inner lining of stomach, intestines, gallbladder, uterus, uterine tubes, and some kidney tubules?
Simple Columnar Epithelium
What are the three functions of simple columnar epithelium?
-Absorption
-Secretion of mucus and other products
-Movement of egg and embryo in uterine tube
What is the function of pseudostratified columnar epithelium?
Secretes & propels mucus
What are the two locations for pseudostratified columnar epithelium?
-Respiratory tract from nasal cavity to bronchi
-Portions of male urethra
Where is stratified squamous epithelium - keratinized found?
Epidermis
What are the two functions of stratified squamous epithelium - keratinized tissue?
-Resists abrasion & penetration by pathogenic organisms
-Retards water loss through skin
What are the five locations of stratified squamous epithelium - Nonkeratinized?
-Tongue
-Vagina
-Anal canal
-Esophagus
-Oral Mucosa
What is the function of stratified squamous epithelium - nonkeratinized?
Resists abrasion and penetration by pathogenic organisms.
What are the three locations of stratified cuboidal epithelium?
-Sweat gland ducts
-Egg producing vesicles (follicles) of ovaries
-Sperm-producing ducts (seminiferous tubules) of testes
What are the three functions of stratified cuboidal epithelium?
-Contributes to sweat secretion
-Secretes ovarian hormones
-Produces sperm
What four locations is urothelium found at?
-Urinary tract - Part of kidney
-Ureter
-Bladder
-Part of urethra
What are the two functions of urothelium?
-Stretches to allow filling of urinary tract
-protects underlying tissues from osmotic damage by urine
What tissue underlies nearly all epithelia?
Areolar Tissue
What tissue surrounds blood vessels, nerves, esophagus, & trachea?
Areolar Tissue
What tissue is found in the fascia between muscles, the visceral layers of the pericardium & pleura, as well as the mesenteries?
Areolar Tissue
