Its consist of smooth muscle.
As capillaries do not have tunica media , so diffusion is comparatively easy in these blood vessels.
15) vertebral artery.
1st heart sound is produced due to closure of bicuspid and tricuspid valve.
Tricuspid Valve Area - Fourth left ICS, left sternal border.
Bicuspid Valve Area -Fifth ICS, left mid-clavicular line.
19) peripheral blood pressure or diastolic blood pressure.
20) systolic blood pressure.
