Which of the following is true about the regulation of blood flow to the skin?
It is regulated by local factors operating within the skin
What influences cardiovascular function?
All of the above
How are cardiovascular responses to exercise achieved?
Through changes in the activity of autonomic nerves to the heart and blood vessels
Which of the following is the primary function of capillaries?
Permitting exchange of materials between the blood and the tissues
What is the formula for mean arterial pressure (MAP)?
MAP = CO * TPR
What is the purpose of the lymphatic system?
Transporting excess filtrate back to the blood
Which of the following is a short-term regulatory mechanism for mean arterial pressure (MAP)?
Baroreceptor reflex
During Mio's attempts to stand, her heart rate increases while her blood pressure decreases. Why does this happen?
The baroreceptor reflex is compensating for the drop in blood pressure in order to increase blood perfusion to the brain.
What is the main influence on vascular resistance in the systemic circuit?
Vessel radius
Which blood vessels function as a pressure reservoir that maintains blood flow throughout the cardiac cycle?
Arteries
What is the average arterial pressure during the cardiac cycle called?
Mean arterial pressure (MAP)
Test your knowledge on the role of arterioles in regulating blood flow and maintaining mean arterial pressure (MAP). Explore how organ vascular resistance and MAP influence blood flow through different systemic organs. Assess your understanding of the intrinsic control of organ vascular resistance and the factors that determine organ blood flow.
