Week 2- Integration of Tissues

Question 1

Organ

Answer 1

A structure that is composed of 2 or more tissue types that work together to perform specific, complex functions

Question 2

Body membranes

Answer 2

-formed from an epithelial layer that is bond to an underlying connective tissue
-line body cavities or joint surface, cover viscera, or cover body’s external surface

Question 3

4 Types of Body Membranes

Answer 3

1) Mucous
2) Serous
3) Cutaneous
4) Synovial

Question 4

Mucous membrane

Answer 4

-lines passageways and compartments that eventually open to external environment
-digestive, respiratory, urinary, and reproductive tracts
-formed by an epithelium and an underlying connective tissue called lamina propria
-perform absorptive, protective, or secretory functions or a combination of these

Question 5

Serous membrane

Answer 5

-line body cavities that typically do not open to external environment and covers external surface of may organs
-composed of simple squamous epithelium called mesothelium
-parietal layer: lines inside of body cavity
-visceral layer: covers surface of internal organs

Question 6

Cutaneous membrane

Answer 6

-largest body membrane
-skin
-composed of keratinized stratified squamous epithelium (epidermis) and an underlying layer of connective tissue (dermis)
-functions include protecting internal organs and preventing water loss

Question 7

Synovial membrane

Answer 7

-specialized connective tissue that lines some joints in the body
-cells within membrane secrete synovial fluid that reduce friction among moving bone parts and distributes nutrients to cartilage on articular surfaces of bone
