BIOS-255 Week 2 Discussion Question: Blood Flow Dynamics
Cardiac output is the amount of blood ejected from the left or right ventricle in any given minute.
Cardiac output must … maintained in order to keep sufficient blood flow through the capillaries.
Identify the factors that directly affect blood flow in the circulatory system.
BIOS 255 Week 2 Discussion Question: Blood Vessel Structure
Let’s start by discussing the structure of our blood vessels. Let’s each take a characteristic of (1)
arteries, (2) veins, or (3) capillaries. Build upon what your classmates say to enable us to have a
more full understanding of these vessels that are essential for our existence.
