30 Questions
What is the meaning of homeostasis?
Seeking to maintain variables within a range near a preferred value
What happens to endothelial cells when exposed to low wall shear stress?
They change their features
In which part of the body can recirculation behavior be found?
Neck
What can low shear stress on a vessel wall lead to?
Formation of plaque
What conditions can trigger changes due to homeostasis?
Medical devices and others
What kind of disease can aortic aneurysms be related to?
Pressure-related disease
Which part of continuum mechanics deals with liquids and gasses?
Fluid dynamics
What two main properties of fluids are needed for the rest of the course in fluid mechanics?
Density and viscosity
When is a fluid called incompressible?
When the pressure is constant
What type of fluid starts flowing with high shear rate and has decreasing viscosity with increasing shear rate?
Shear thinning fluid
Which substance is not really a continuum according to the course?
Blood
What type of non-Newtonian fluids have increasing viscosity with shear rate?
Shear thickening fluids
Which property is derived from both density and viscosity of fluids?
Incompressibility
What needs to be understood for optimal treatment of lung disease through an inhaler?
The spread of medicine in the lungs
What is the main function of homeostasis within the human body?
To maintain key regulated variables within a range near a preferred value
Where can recirculation behavior be observed in the body?
Carotid Bifurcation
What effect can low wall shear stress on a vessel wall have?
Lead to stenosis (narrowing in the vessel) as plaque forms and narrows the lumen
In what ways can aortic aneurysms be related to diseases?
Pressure disease or a wall shear stress disease
What is the impact of blood flow on endothelial cells?
They change their features depending on the wall shear stress they are exposed to
How are soft tissues involved in homeostasis?
