Cardiovascular physiological concepts
15 important questions on Cardiovascular physiological concepts
What are characteristics of living organisms?
2. Interact with environment
3. Adapt to changing circumstances
What are the two types of metabolism?
Anabolism = uses energy to construct substances
From which substances is energy derived?
Proteins = 4.3 kcal/g
Lipids = 9.4 kcal/g
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
Unicellular organisms, how do they obtain nutrients and get rid of waste products?
How is obtaining nutrients and get rid of waste products regulated in higher organisms?
What are the roles of the circulatory system?
- fast chemical signaling by circulating hormones and neurotransmitters
- dissipation of heat (thermoregulation)
- mediation of inflammatory and host defense responses
What is transmural pressure?
What is hydrostatic pressure/
... Dia
What is flow? And how is it calculated?
-> ml/s or l/min
Flow = area * mean velocity
usually a parabolic profile: v(mean) = 0.5*v(max)
How is the cardiac output calculated?
MAP = mean arterial BP
CVP = central venous blood pressure
SVR = systemic vascular resistance
How is the MAP (mean arterial BP) calculated?
DBP = diastolic blood pressure
SBP = systolic blood pressure
How is the hydrolic resistance calculated?
n = viscosity
What is imporant for viscosity? And how is it calculated?
Stress = force/area
Rate = velocity gradient = dv/dx
viscosity (n) = shear stress/shear rate
How is the resistance calculated in series? And parallel?
Parallel: 1/Rtot = 1/R1 + 1/R2 + 1/R3 + ...
What causes pressure in the circulation?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
