Peripheral circulation Flashcards
Mechanoreceptors are loacted
In the walls of aortic arch and carotid sinus
LV pressure in Systemic circulation
120/0
Mean Pulmonary A. Pressure in Pulmonary circulation
15
LA pressure in pulmonary circulation
5-10
Ciculation affect on exercising skeletal muscle
- Decrease vascular resistance
- Increase BF
- Increase capillary P
- Increase Capillary filtration
- Increase Lymph flow
CO=
HR X SV
Aorta pressure in the Systemic circulation
120/80
Pulmonary ciruit affect of exercise
- Increase in CO
- Decrease in Pulmonary vascular resistance
- Increase in pulmonary blood volume
- Increase in number of perfused capillaries
- Increase rate of gas exchange by increasing Capillary surface area
What factors decrease MAP
Decreased sympathetic activity
EPI that stimulates β2
NO
Preload is determined by
Venous return
Arterial system affect of excercise
Hemoglobin still fully saturated
Large decrease in TPR due to dilation of skeletal muscle bed
Blood flow is proportional to
Tissue metabolism
Mechanoreceptors respond to
Rise in intravascular P
Pulmonary A pressure in the Pulmonary Circulation
25/8
RV pressure in Pulmonary Circulation
25/0
