Cardio test Flashcards
What type of blood vessels carry blood to the far reaches of the body?
Muscular arteries
These have proportionately thicker walls.
How many chambers are in the heart?
Four
What is the approximate size of the heart?
Equal to a fist
What age range does the heart reach its full adult size?
12-25
What are the largest arteries that stretch and relax with the beats of the heart?
Elastic arteries
What are short connecting vessels that attach to approximately 20-100 capillaries?
Metarterioles
Which chamber receives blood from one of the vena cavae?
Right atrium
Which chamber pumps blood into the left ventricle?
Left atrium
Which chamber is responsible for pressurizing the systemic circuit?
Left ventricle
Which chamber pumps deoxygenated blood received from one of the atria?
Right ventricle
Is it true that approximately 2/3 of the mass of the heart is to the left of the midline of the body?
True
Is it true that adult heart mass is 1/1000 of body weight?
False
Is it true that the heart is closer to the posterior side of the body?
False
Do both atria receive deoxygenated blood?
False
Do the terms bicuspid and mitral refer to the left AV valve?
True
What results from a lack of oxygen to a body part?
Ischemic tissue
This condition indicates tissue damage due to insufficient oxygen.
What is a myocardial infarction?
A heart attack resulting from the death of heart muscle
Is it true that no cell is far removed from a capillary?
True
What causes pericarditis?
The rubbing of the visceral and parietal layers of the pericardium
Are pig parts occasionally used to repair human hearts?
True
Can atherosclerosis be prevented with a proper diet?
True
What is gangrene a result of?
Severe cases of ischemia due to peripheral vascular disease
Are stents artificial pathways that help keep vessels closed?
False
What causes varicose veins?
Incompetent valves
What is a hemorrhoid?
A varicose vein of the anal canal that can be caused by severe defecation pressure
Will blood divert to areas of higher need?
True
Are the blood vessels in the human body always at capacity?
False
As a result of hemodynamics, will cells that are more active receive a greater supply of blood?
True
What drives blood flow from one area to another?
The pressure gradient between the right atrium and the left ventricle
What does the acronym CPR mean?
Cardio pulmonary resuscitation
What structure provides collateral protection against coronary artery disease?
Anastomosis
What is the result of a mitral valve prolapse?
Aortic regurgitation
Which structure is the muscular wall of the heart?
Myocardium
Which structure is responsible for initiating the conduction of electrical impulse through heart tissue?
Sinoatrial node
Which of the following is not a risk factor concerning hypertension?
None of the above
Which location would not be good to take a pulse?
Thigh
What makes the sound heard during systolic contraction?
Ventricular contraction
what are the 6 baby
- Umbilical arteries: carry blood to the fetus.
- Placenta: location of nutrition and oxygen exchange between maternal and fetal, but no mixing of blood.
- Umbilical vein: carries oxygenated blood from placenta to fetus.
4.Ductus venosus: carries oxygenated blood to the inferior vena cava.
5.foramen ovale: hole that allows bypass of the fetal lungs. - Ductus arteriosus: pulmonary artery that allows bypass of fetal lungs
Sphygmomanometer short answer question
Pump sphygmomanometer until beyond 120/ beyond patients blood pressure limit, take out stethoscope, place it on the artery, release blood pressure little by little, use it to find the systolic blood pressure then wait more to find the diastolic
