Fluid compartments
Approximately what percentage of fluid does intracellular fluid that make up in the body?
60%
What are main vascular transport methods?
Veins, arteries, capillaries.
What is the key word that describes homeostasis?
Balance
What is incidence?
Rate of new cases or events over a specified time period for the population at the risk
What is the purpose of the interstitial fluid compartment?
Helps maintain homeostasis, provide nutrients and remove waste products
What molecule allows for fluid to move across the cell membrane?
Aquaporin protein
Name the two types of thermoreceptors, and one location for both types.
Central: Organs, spinal cord, hypothalamus
Why do researchers use person-years?
This measure is used in epidemiological studies because participants may join, leave, or develop disease at different times, so researchers need a way to account for different observation periods
Name 3 types of fluid compartments that are in the extracellular fluid that's not plasma and interstitial fluid
Pleural fluid, Pericardial fluid, Peritoneal fluid, Aqueous humour, Cerebrospinal fluids and Lymph
Which way does water move if extracellular fluid is hypotonic?
Water moves from extracellular environment to intracellular
Name all 4 processes mentioned that occur during out of normal body temperatures
Vasodilation, Shivering, Vasoconstriction, Sweating
In a study measuring disease incidence:
Person A stayed in the study 12 months
Person B developed the disease after 6 months
Person C left the study after 3 months
During the study, 1 new case occurred.
Calculate the incidence rate per person-year.
