• High blood pressure- heart disease, kidney failure.

• Low blood pressure- kidney failure and chest pain.

• Systolic- pumping pressure measured in your arteries(higher number)

• Diastolic- hearts resting pressure measured in your arteries(lower number)

Careers• EKG tech- administer tests having to do with the

heart• Medical data analyst- construct spreadsheets

and reports that include information on patients• Cardiac technician- performs diagnostic

examinations at the request of a physician in invasive cardiology, noninvasive cardiology and/or peripheral vascular study

• EMT- perform emergency medical procedures needed to maintain a patients airway and cardiovascular circulation

Tissues• Connective- supports and binds other tissues• Nervous- main component of nervous system• Muscle- soft tissue that composes the muscles• Epithelial- lines surfaces of structures through

out the body

Study Techniques• Listening to music• Reading key facts• Skim over text to answer essential questions
