1. Aortic Diastolic Pressure 1. High TPR = high DP 2. High HR = high DP 3. High SV = high DP 2. Aortic Systolic Pressure 1. High Contractility = high SP 2. High SV = high SP 3. Low Compliance = high SP
yex  https://cvphysiology.com/Microcirculation/M012 This helps somehow, the first part about capillary pressure. +  
usmlelol  that's the exp part:: The average capillary hydrostatic pressure is determined by arterial and venous pressures (PA and PV), and by the ratio of post-to-precapillary resistances (RV/RA). An increase in either arterial or venous pressure will increase capillary pressure; however, a given change in PA is only about one-fifth as effective in changing PC as the same absolute change in PV. Because venous resistance is relatively low, changes in PV are readily transmitted back to the capillary, and conversely, because arterial resistance is relatively high, changes in PA are poorly transmitted downstream to the capillary. +

Here's a GREAT video explaining ultrasound findings of pregnancy. @9:57 is a great picture so far with labels of the yolk sac, gestational sack, fetal pole, and amnion. One thing the person explaining said that I thought would be good to keep in mind is that the yolk sac looks like a cheerio inside the gestational sac. Also, this site has a bunch of pictures as well: https://radiopaedia.org/articles/first-trimester?lang=us.
