Answer 2

he body surface, line body cavities, and cover the inner surfaces of the hollow organs such as the digestive, reproductive, and respiratory passageways.

Question 3

two major categories or types of body membranes:

Answer 3

Epithelial tissue membranes, Connective tissue membrane

Question 4

visceral means

Answer 4

organs

Question 5

three types of epithelial tissue membranes in the body:

Answer 5

Cutaneous membrane,Serous membranes, Mucous membranes

Question 6

Cutaneous membrane

Answer 6

The cutaneous membrane or skin, is the primary organ of the integumentary system. It fulfills the requirements necessary for an epithelial tissue membrane in that it has a superficial layer of epithelial cells and an underlying layer of supportive connective tissue.

Question 7

Serous membranes

Answer 7

is composed of two distinct layers of tissue. The epithelial sheet is a thin layer of simple squamous epithelium.

Question 8

Mucous membranes

Answer 8

-Mucous membranes contain an epithelial layer and a fibrous connective tissue layer.

Question 9

Parietal

Answer 9

lines wall of body cavity

Question 10

Visceral

Answer 10

covers organs within body cavity

Question 11

Pericardium

Answer 11

parietal and visceral layers line a fibrous sac around the heart and a visceral layer covers the heart wall

Question 12

Pleura

Answer 12

parietal and visceral layers line walls of thoracic cavity and cover the lungs

Question 13

Peritoneum

Answer 13

parietal and visceral layers line walls of abdominal cavity and cover the organs in that cavity

Question 14

Pleurisy

Answer 14

Inflammation of the serous membranes that line the chest cavity and cover the lungs

Question 15

Peritonitis

Answer 15

Inflammation of the serous membranes in the abdominal cavity that line the walls and cover the abdominal organs

Question 16

Connective tissue membranes

Answer 16

Do not contain epithelial componentsProduce a lubricant called synovial fluid.Connective tissue membranes are smooth and slick.Connective tissue membranes reduce friction between opposing surfaces of bones in movable joints.
