exam 1: tissues

Question 1

four major families of tissues

Answer 1

• epithelial tissue
• connective tissue
• muscular tissue
• nervous tissue

Question 2

what is serous sacs function

Answer 2

• lubricated sacs that surround the associated organs
• they are double-layered smooth membrane that secretes serous fluid which lubricates the membrane and allows free movement of the organs within the cavity

Question 3

epithelial tissue

Answer 3

covers body surfaces, lines hallow organs and cavities, and forms glands

Question 4

connective tissue

Answer 4

connects and supports and protects organs while distributing blood vessels to other tissues

Question 5

muscular tissue

Answer 5

contracts to make body parts move and generates heat in the process

Question 6

nervous tissue

Answer 6

carries information from one part of the body to another

Question 7

membrane

Answer 7

a this pliable tissue that covers, lines, partitions, or connected structures

Question 8

serous membrane

Answer 8

a slippery membrane associated with body cavities that does not open directly to the exterior (the pleural and pericardial sacs are examples). it covers the viscera within the thoracic and abdominal cavities and also lines the walls of the thorax and abdomen

Question 9

parts of a serous membrane

Answer 9

• the parietal layer: a thin epithelium that lines the walls of the body cavities
• the visceral layer: a thin epithelium that covers and adheres to the viscera within the body cavity
  because the parietal and visceral membranes are continuous with one another, they form a serous sac

Question 10

serous cavity

Answer 10

between the parietal and visceral layers is a potential space called the serous cavity. It contains a small amount of lubricating fluid called serous fluid that reduces friction between the two layers, allowing the viscera to slide freely during movements such as the pumping of the heart or the inflation and deflation of your lungs when you breathe in and out.
