This set of Tissue Engineering Question Paper focuses on “Liver Biomechanical Properties and Haemodynamics”.

1. Typical liver shear moduli range from ___________
a) 200 to 5000 Pa
b) 5 to 100 Pa
c) 1 to 20 kPa
d) 100 to 900 kPa

Answer: a
Explanation: The elastic (Young’s) modulus E and shear modulus G are proportions of a material’s capacity to oppose distortion under a connected burden. Ordinary liver shear moduli run from 200 Pa to 5 kPa, and run of the mill versatile moduli run from ∼1 to 20 kPa. On the off chance that the liver is thought to be an incompressible material (i.e., to keep up a steady volume under mechanical stacking), which is a typical supposition in numerous biomechanics thinks about, at that point to a first guess the flexible modulus is generally identical to multiple times the shear modulus (E ≈ 3G).

2. Many studies have assumed that the liver parenchyma is anisotropic material.
a) TRUE
b) FALSE
View Answer

Answer: a
Explanation: Numerous examinations have accepted that the liver parenchyma is an isotropic material, implying that its mechanical properties are similar when estimated toward any path.

3. The liver is known to be linearly ___________ in shear up to shear strains of 0.2%.
a) viscoelastic
b) conductive
c) reflective
d) strong
View Answer

Answer: a
Explanation: Viscoelasticity alludes to materials that display time-subordinate highlights in their mechanical reaction, for example, creep, stress unwinding, or strain rate reliance. The liver is known to be directly viscoelastic in shear up to shear strains of 0.2%. Past this breaking point, it shows nonlinearly viscoelastic conduct, with a shear unwinding modulus that is subject to strain.

4. Liver exhibits nonlinear stress-strain behavior.
a) TRUE
b) FALSE
View Answer

Answer: a
Explanation: In the same way as other natural tissues, the liver displays nonlinear pressure strain conduct under huge mishappenings. Therefore, the liver is regularly demonstrated as a hyperelastic material.
