Heart
These are the superior recieving chambers of the heart.
What are the atria?
These tubes transport blood away from the heart.
What are arteries?
Which blood cells carry oxygen?
Red blood cells
Blood enters the heart through which chamber from the body?
Right atrium
What is the life-saving device that delivers a high-energy electric shock to the heart, resetting its rhythm during sudden cardiac arrest?
Defibrillator
What do valves do in the heart?
Prevent backflow of blood
Which blood vessels carry blood back to the heart?
Veins
Which blood cells fight infection?
White blood cells
What valve is between the right atrium and right ventricle?
Tricuspid valve
What is the most common heart arrhythmia causing the heart's upper chambers (atria) to beat chaotically?
Atrial fibrillation
Which valve is between the left ventricle and aorta?
mitral (bicuspid) valve
What blood component helps with clotting?
Platelets
Which vessels bring oxygenated blood back to the heart?
Pulmonary veins
What happens during a myocardial infarction (heart attack)?
Blood flow to heart muscle is blocked, causing tissue death
What is the pacemaker of the heart that initiates the initial electrical impulse?
Sinoatrial (SA) node
Which vessels carry blood from the heart to the lungs for oxygenation?
Pulmonary arteries
What is the protein in red blood cells that binds to oxygen?
After leaving the right ventricle, where does blood go?
Pulmonary Arteries to the Lungs
A patient describes they are feeling chest pain associated with their heart. What is the name of this symptom you would record in the medical report?
Angina pectoris
Why is the left ventricular muscle thicker than the right ventricular muscle?
The left ventricle pumps to the entire body, whereas the right only has to pump to the lungs
What is the condition where plaque builds up in the blood vessels leading to blockages?
Atherosclerosis
What are the names of the top and bottom numbers in a blood pressure reading?
Systole - Top number (when heart is contracting)
Diastole- bottom number (when heart is relaxing)
Put the following in order from where deoxygenated blood enters the heart to oxygenated blood leaving the heart to the body.
Right ventricle, left ventricle, right atrium, left atrium, Aorta, Pulmonary Veins, Pulmonary Arteries, Vena Cava, lungs
Vena Cava --> right atrium --> right ventricle --> pulmonary arteries --> lungs --> pulmonary veins --> left atrium --> left ventricle --> aorta
A 68-year-old male with a history of high blood pressure and smoking presents with a deep, throbbing pain in his abdomen and lower back that has been worsening over the past week. On physical exam, a pulsating mass is felt in the abdomen, and an ultrasound reveals an enlarged section of the aorta measuring significantly wider than normal. Based on these findings, what is the diagnosis?
Aortic aneurysm
