Benjamin Cummings. InterActive Physiology®
8-System Suite CD-ROM, Benjamin Cummings, 2004.
Objective:
To explain in short essays or with
diagrams the role of vessel size and other factors on peripheral resistance,
the control of vascular resistance by nerves and hormones, the
inter-relationships among vascular resistance, blood volume, cardiac output and
blood pressure, and the role of capillary and interstitial pressure on fluid
movement, at the level of 85% proficiency for each student.
In order to achieve this objective, you will need to be able
to:
- Explain the role of vessel diameter, blood viscosity, and
vessel length on peripheral resistance.
- Explain how changes in hematocrit, body fat, and vessel
elasticity can affect vascular resistance.
- Describe the effects of neurotransmitters and hormones on
vascular resistance.
- Describe the major autonomic, endocrine and cardiovascular
effects of changes in the activity of arterial baroreceptors.
- Describe the effects of changes in blood volume on cardiac
output and blood pressure.
- Describe the role of capillary hydrostatic pressure,
interstitial fluid hydrostatic pressure, and osmotic pressure in the net
movement of water into or out of capillaries.
