Histology

• simple squamous epithelium is found in the air sacs of the lungs and its function is to allow diffusion and filtration in sites where protection is not important
• Simple cuboidal epithelium is found in kidney tubules and ovary surface and it provides secretion and absorption
• Simple columnar epithelium is found in most digestive organs and specializes in absorption
• Pseudostratified columnar epithelium lines the upper respiratory tract and secretes mucus
• Stratified squamous epithelium is found in linings of the esophagus, mouth, and vagina and protects areas subject to abrasion
• Transitional epithelium lines the bladder, ureter, and urethra and stretches to allow distention
• Smooth muscle tissues is located in the walls of hollow organs and propels substances along internal passageways
• Areolar connect tissue is found under epithelia of the body and cushions organs and plays a role in inflammation
• Adipose connective tissue is located under the skin in subcutaneous tissues and provides food fuel reserve and prevents heat loss
• Reticular connective tissue is found in lymphoid organs and forms a soft internal skeleton to support other cell types
• Dense regular connective tissue is found in tendons and ligaments and attaches muscles to bones or muscles and withstands tensile stress when pulled in on direction
• Dense irregular connective tissue is found in fibrous capsules of organs and joints and withstands tension exerted in many directions
• Elastic connective tissue is found in the walls of large arteries and allows recoil after stretching
• Hyaline cartilage is found in the trachea, nose, and larynx and supports and reinforces while resisting compressive stress
• Elastic cartilage is found in the external ear and maintains shape while allowing flexibility
• Fibrocartilage is found in the pubic symphysis and resists compressive shock
