• Venous Return

• Stroke Volume

• Cardiac Output

The volume of blood pumped from the left ventricle of your heart in 1min (L/min)

• Cardiac Output

The volume of blood pumped from the left ventricle with each heartbeat

• Heart Rate

The process of analyzing differences in alleles (DNA) or detect mutations in DNA is to compare them using a process called _______________ or RFLP which copies the DNA sample, adds in restriction enzymes that may cut the sample at specific places and analyze the differences on a gel.
