M7U5: SEROUS FLUIDS

Question 1

Pleural, pericardial, and peritoneal cavities are covered with ___ cells

Answer 1

mesothelial

Question 2

This membrane lines the cavity

Answer 2

parietal membrane

Question 3

This membrane covers the organs within the cavity

Answer 3

visceral membrane

Question 4

Serous fluid is produced and maintained by plasma ultrafiltration by the ___ and absorption by the lymphatic system through the ___

Answer 4

parietal membrane

visceral membrane

Question 5

The process of serous fluid formation and absorption is dynamic and is controlled simultaneously by ___ (4)

Answer 5

1. permeability of the capillaries in the parietal membrane
2. the hydrostatic pressure in these capillaries
3. oncotic pressure (or colloid pressure) produce by proteins within the capillaries
4. absorption of fluid by the lymphatic system

Question 6

What may occur to the serous fluid in the cavities if there is a decrease in oncotic pressure ?

Answer 6

more fluid is formed

Question 7

This is known as the disruption of serous fluid formation and reabsorption causes an increase in fluid between the membranes

Answer 7

effusion

Question 8

___ results from non-inflammatory processes that disrupts the balance in the regulation of fluid filtration and reabsorption

Answer 8

transudate

Question 9

Transudate occurs in condition that increases hydrostatic pressure (e.g. ___, ___, ___)

Answer 9

congestive heart failure
hepatic cirrhosis
shock

Question 10

Transudate occurs in condition that decreases oncotic pressure (decreased protein synthesis [e.g, ___, ___]; increased protein synthesis [e.g, ___]

Answer 10

hypoproteinemia in nephrotic syndrome
liver disease

kidney disease
