How many types of circulation are there?
100
4
How many chambers does the heart have?
100
High blood pressure
What is hypertension?
100
build up of plaque on artery walls.
What is atherosclerosis?
100
bypass surgery
What is it called when healthy arteries are taken from elsewhere in the body to bypass a blockage?
200
3
How many functions does the circulatory system have?
200
left . Pumps blood all over the body
Which ventricle is bigger and why
200
systolic pressure
What measures the pressure in a blood vessel during ventricular contraction?
200
Hardening” of an artery due to atherosclerotic build up.-Reduces the vessels elasticity
What is arteriosclerosis?
200
EKG
What measures the electrical activity of the heart?
300
Transport blood away from the heart-usually Oxygen rich blood
What are the functions of the arteries?
300
1 way valves prevent blood from flowing back into a chamber
What is the function of a one way valve?
300
Sphygmomanometer ( Blood Pressure cuff.)
What is the instrument used to measure blood pressure?
300
Stroke-an acute injury where blood flow to the brain is interrupted
What is a stroke?
300
thin flexible tube is guided through the blood vessels then dye is injected into the blood stream and blocked arteries are located on a monitor.
What is a angiography?
400
transports blood towards the heart –usually Oxygen poor blood
What are the functions of veins?
400
pump blood out of the heart-Right and Left
Function of the ventricles?
400
diastolic pressure
What measures the pressure placed on a blood vessel when a ventricle is relaxed?
400
Need for oxygen exceeds supply causing a tightness or a feeling of pressure in the chest-feels like a heart attack. Oxygen Capacity-Normal 93% Less-Angina
What is angina pectoris
400
tube is inserted into a blocked artery. The balloon is inflated against the artery walls then deflated and removed.
What is an angioplasty?
500
1. Skeletal 2. Smooth 3. Cardiac
Name the three types of muscles and their functions
500
blood that has been depleted of O2 and contains carbon dioxide and waste is carried to the heart by the way of 2 blood vessels called “The Vena Cava”.
What is the function of the Vena Cava?
500
normal-120 over 80 HBP- 140 over 90
What is the normal ranger of blood pressure and high range of blood pressure?
500
Congestive Heart Failure
What is it called when the heart does not pump blood effectively and blood backs up into the lungs and drowns the person.
500
1-Tobacco Smoke: smokers develop heart disease 2-4X more then non-smokers 2-High Blood Cholesterol 3-High Blood Pressure- increases the hearts workload-causing the heart to become thicker and stiffer. 4-Physical Inactivity 5- Obesity/Overweight 6-Diabetes-3/4 people with diabetes die of some form of heart disease or blood vessel disease 7-Stress-may cause overeating/smoking or smoke more then usual 8-Alcohol-high triglycerides/irregular heartbeat
What are 5 out of the 8 controllable factors to reduce cardiovascular disease?
