Answers to Last Issue’s Heart Quiz
1.There are two systems in which blood travels in the cardiovascular system. What are they?
Pulmonary and Systemic: The pulmonary system starts with dexoygenated blood coming out of the right ventricle. It is pumped up through the pulmonary artery and circulates around your lungs where it is oxygenated by the air you breathe in. Blood then returns to your left atrium to be pumped to the rest of your body in the systemic system.
2. Blood flows through the heart in this order: right atrium, right ventricle, pulmonary circuit, left atrium, left ventricle … into what vessel is the blood pumped from the left ventricle?
The aorta extends down into the abdomen where it splits into two smaller arteries to deliver oxygenated blood to all parts of the body.
3.nIa blood pressure measurement reading 120/80, the number on the bottom is which reading?
The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats to fill with blood. (The systolic, or top number, is when your heart beats to push blood through your arteries.)
4 .Which chamber receives the deoxygenated blood from the systemic system first? The right atrium receives blood
5.What is the medical term for a severe constricting pain in the chest due to an insufficient blood supply to the heart?
Angina pectoris is pain due to coronary artery disease which usually happens because one or more of the heart’s arteries is narrowed or blocked.
6.What drug would you use for relief of the constricting chest pain?
Nitroglycerin dilates or widens blood vessels, making it easier for blood to flow through them and easier for the heart to pump.
7. Allmas mass of specialized muscle on the back wall of the right atrium, also known as the pacemaker, is medically known as what? The sinoatrial node or sinus node sends electrical impulses further down to the atrioventricular node to cause the heart to contract.
8. When you check the pulse of someone by placing two fingers on the side of their neck, you are feeling the blood being pumped through which vessel(s)?
Carotid artery. There are eight main pulse points in the human body. These additional pulse points are located in the wrists, at the sides of the lower jaw, at the temples, on the inner biceps, behind the knee, in the groin and on the upper part of the foot.
9. The system of arteries that supply the heart with its own separate supply of blood is called coronary
The four primary coronary arteries are lo- cated on the surface of the heart: right main coronary artery, left main coronary artery, circumflex artery and left anterior descending artery.
10. What is meant by the term hypertension? High Blood Pressure. Hypertension, known as the silent killer because many do not realize they have it, is characterized by a consistent high pressure when the blood pushes through the blood
11. Which is not a result of hypertension? Headache. Chronic hypertension also may cause stroke, dementia, eye damage, sexual dysfunction, bone loss and trouble
12. What is the correct medical terminology for a heart attack?
Myocardial infarction. A heart attack occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.
