What else can I help you with?
Would vasoconstriction decrease peripheral resistance?
No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.
What causes peripheral resistance?
Peripheral resistance is the force against blood flow. In most cases, an increase in peripheral resistance would be caused by an increase in vasoconstriction, which would decrease blood flow. Other factors can influence vasoconstriction, such as circulating angiotensin II levels, cortisol levels, drugs such as cocaine and other adrenergic agonists, blood volume, atherosclerosis, emboli, renal diseases and increased intra-cranial pressure. An increase in blood pressure will also be caused by vasoconstriction and the mentioned factors.
Would decreased airway resistance make it difficult for a person to exhale?
Yes
What would you expect to see in elevated numbers in a peripheral blood sample after donating a pint of blood?
erythrocytes
Whats the function of valves in the peripheral veins?
Valves in the peripheral veins prevent blood from backflow during the off beat of the heart. If not for the valves, the flow of blood would tend to pool at the extremities.
Autonomic tone of peripheral blood vessels would be greatest when?
When sympathetic stimulation is increased.
Would your skin experience a decreased blood flow during exercise?
no
What would you expect to see in increased numbers in a peripheral blood sample after donating a unit of blood?
reticulocytes by jawed akbari
What would experience a decreased blood flow during exercise?
no it actually stimulates blood flow
Which of the following factors would increase the amount of oxygen discharged by hemoglobin to peripheral tissues?
decreased pH, increased temperature or increased levels of CO2
Would skeletal muscles experience a decreased blood flow during exercise?
I could be wrong but, I think it would decrease your blood flow
Which would have the greater effect on vascular resistance?
Vasoconstriction would have a greater effect on increasing vascular resistance compared to vasodilation. When blood vessels constrict, their diameter decreases, leading to increased resistance to blood flow. Conversely, vasodilation results in an expansion of blood vessel diameter, reducing resistance.
