Juan injured his leg and was taken to the ER with a suspected broken bone. What would be the ideal imaging diagnosis mode for him, and what is one advantage and one disadvantage (i.e. potential side effect) of this diagnostic technology?
Example answer, but explore more in notes:
“An x-ray can be used ideally. Get a clear 2D image of the bone to see if fractured. However, it does not compare to CT scans since x-rays are only 2D. Also, radiation is one side effect since it can cause mutations in DNA if conducted too much.
Describe 3 major functions of the heart
- Generating Blood Pressure: Required for blood flow through the blood vessels
- Routing Blood: Two pumps, moving blood through the pulmonary and systemic circulations
- Regulating Blood Supply: Adjusts blood flow by changing the rate and force of heart contractions as needed
Recognize the Navier-Stokes equation and all of its parts!
Inertia force = (-)Pressure gradient + Body Force + Viscosity
Heart valve replacement is a common procedure in cardiology field. Explain the difference between a xenograft valve and mechanical valve. List one advantage and one disadvantage associated with EACH type of valve
Example answer, but review from slides
- Xenograft: Animal one is good because if taking immune suppressing drugs your immune system won’t attack it, but disadvantage is it only lasts for like 10 years.
- Mechanical: Artificial one made by biomaterials which allow it to last longer than xenograft. However, a disadvantage is that it can crush RBCs which in turn cause coagulation.
Explain the functions/ roles of Caspase 9 enzyme and gRNA of CRISPR genome editing technology
Look at notes.
