Answer 1

1. systolic blood pressure

the first Korotkoff sound will be heard when the cuff presuure becomes equal to the systolic blood pressure of the patient.systolic blood pressure is the pressure exerted on the walls of the arteries during the contraction of the ventricles.

2.The answer is E

the lymph capillaries are attatched to the tissues by the filaments.there are minivalves in the lymphcapillaries.The fluid enters the lymphatic capillaries by leaking through the minivalves located in the junctions of the endothelium.The minivalves prevent the lymph from flowing back into the tissues.
