What main artery would be affected by a high systolic blood pressure number?

woolyfrog:

@dude

woolyfrog:

Hey sam

Sam:

hi

Sam:

I assume aorta?

Sam:

Wait let me check

woolyfrog:

Okay

Sam:

Systolic pressure is when blood pumps out of the heart's pressure

woolyfrog:

Yes

Sam:

radial artery?

Sam:

I just think it's aorta

woolyfrog:

Yeah it's Aorta not Radial artery

woolyfrog:

wait can you explain to me why the Aorta would be affected

woolyfrog:

I need evidence to support my answer it says.

Sam:

OK lets think again, high systolic blood pressure number means the pressure in your arteries is high. The 'main' artery can be any artery

Sam:

Really, the pressure measures across all arteries

woolyfrog:

How does the pressure get high?

Sam:

Because the volume in LV is low?

woolyfrog:

what's lv? non-abbreviated

Sam:

Pressure is inversely proportionate with volume

Sam:

LV - left ventricle

Sam:

inversely proportional*

woolyfrog:

http://prntscr.com/izxwfk It's C or B I'm going with B.

Sam:

Have you got the answer just wondering

woolyfrog:

no

Sam:

Think about yourself, Cellular respiration, what do you need, Glucose- that's sugar, Oxygen- You're breathing, right? Energy in the form of ATP. What you don't need is CO2, you exhale CO2 in exchange for oxygen in your body, Water- You sweat, perspire

Sam:

Alright

woolyfrog:

B

Sam:

Good

woolyfrog:

http://prntscr.com/izy00q I'm guessing b

woolyfrog:

its a guess the last question I kind of knew the answer but this one is a bit of a guess

woolyfrog:

@Sam

Sam:

Why is the amount of fluids when you're dehydrated increases

woolyfrog:

I said b which says the fluid decreases

Sam:

mm

woolyfrog:

brb

Sam:

You're right

woolyfrog:

thank you
