Heart circulation Flashcards
(25 cards)
The blood from the brain and upper extremities flows back to the heart via the:
Superior vena cava
The blood from the lower extremities flows back to the heart via the:
Inferior vena cava
The blood from the upper extremities and the lower extremities flows back into what chamber of the heart:
Right atrium
When the right atrium contracts this valve opens:
Tricuspid valve
When the right atrium contracts blood flows into this chamber of the heart:
Right Ventricle
When the right ventricle contracts this valve opens:
Pulmonary valve
When the right ventricle contracts this valve opens:
Pulmonary arteries
Blood flows back to the heart from the lungs after being oxygenated and offloading carbon dioxide:
Pulmonary veins
Blood flows back to the heart from the lungs and empties into this chamber of the heart:
Left atrium
When the left atrium contracts blood empties into this chamber of the heart:
Left ventricle
When the left atrium contracts this valve opens:
Mitral (or bicuspid) valve
When the left ventricle contracts this valve opens:
Aortic valve
When the left ventricle contracts blood flows into this blood vessel:
Aorta
The left ventricle is responsible for this type of circulation:
Systemic circulation
The right ventricle is responsible for this type of circulation:
Pulmonary circulation
What anatomical structure differentiates veins:
Valves (veins have valves to prevent backflow of blood)
What causes the blood to flow back to the heart from the periphery:
Skeletal muscle contraction (also called the “muscle pump”)
What causes the blood to flow to the periphery:
Left ventricular contraction (also known as systole)
Ventricular contraction is also known as:
Systole
Ventricular relaxation is also known as:
Diastole
This is the number one reason providers do not deliver high-quality CPR:
d. Compressing on a hard flat surface
If the patient is not breathing/ventilating, then this is the proper treatment:
b. Rescue Breathing/ ventilations
The most common cause of cardiac arrest in adults is:
c. Pulseless ventricular tachycardia or ventricular fibrillation
The most common causes of cardiac arrest in pediatrics is:
a. Respiratory issues and shock
