increased blood flow and increased permeability of blood vessels

Question 22

what is exudate?

Answer 22

inflammatory fluid at the site of inflammation

Question 23

Answer 23

protein rich fluid
plasma cells
WBC’s
space for healing damaged tissue

Question 24

what is transudate?

Answer 24

refers to the perfusion of normal fluid portion of the blood inot the tissues; due to hydrostatic and osmotic pressure

what are components of vascular inflammation?

Answer 25

hyperemia and stasis

Question 26

what is hyperemia?

Answer 26

increased blood flow

Question 27

what is stasis?

Answer 27

is the slowing of blood flow causing blood to stop

Question 28

what is filtration?

Answer 28

fluid is pushed out of the capillary into the tissue

Question 29

what are characteristics associated with hyperemia?

Answer 29

tumor, rubor, increase in temperature, pain, and reduced function

Question 30

what are the four benefits of fluid exudate in inflammation?

Answer 30

1. dilution of toxins 2. increase pan by swelling 3. antibodies that are retained by the blood 4. contetnt of protein which amplies response

Question 31

what is the effect of albumin into the tissue?

Answer 31

increases osmotoc pressure inot the tissue

Question 32

what is the function of fibrinogen?

Answer 32

mainatains homeostasis and prevents blood lose
