Lecture 1 - Important Concepts Flashcards
What is the only mechanism for movement of water between
interstitial fluid compartment and intracellular fluid compartment
osmotic pressure
What is the only mechanism for the movement of water between intravascular (plasma) fluid compartment and interstitial fluid compartment
osmotic and hydrostatic pressure
Water is lost from the ________ compartment first. Is this an intracellular or extracellular compartment?
Interstitial
Pulmonary circulation characteristics
low pressure and resistance
Systemic circulation characteristics
high pressure and resistance
What are the conductance vessels that return blood to the heart?
Veins and Venules, return to the heart.
What are the conductance vessels that distribute blood from the heart?
Arteries
What are the resistance vessels that regulate blood flow to the organs?
Arterioles
What exchange vessels carry nutrients and waste?
Capillaries
Circulating plasma directly interacts with the interstitial fluid across walls of capillary vessels to
maintain homeostasis
The mechanism responsible for the movement of water between the interstitial fluid compartment and the intracellular fluid compartment is
Osmotic pressure
In a sample of whole blood, hormones and antibodies, as wells as nutrients such as glucose, amino acids, and electrolytes are carried in the
Plasma
Within the systemic circulation, organs are arranged primarily in
Parallel
Distribution of blood flow to the various capillary beds throughout the body is influenced by
local metabolism
Maintaining homeostasis of the internal environment relies on which of the following
Maintaining adequate blood flow thought the tissue capillaries.
Optimizing the chemical composition of the blood for the interstial fluid.
