Blood Flow
The first chamber where deoxygenanted blood enters the heart.
What is the the right atrium?
What is the myocardium?
ECG stands for this and measures this?
What is electrocardiogram and what is the electrical activity of the heart?
Type of blood vessel that caries the blood away from the heart.
What are the arteries?
Circulation that pumps blood throughout the entirety of the body.
What is the systemic circulation?
The valve where blood goes from the right atrium to the right ventricle.
What is the tricuspid valve?
Separates the two sides of the heart.
What is the septum?
P wave represents this in an ECG reading.
What is atrial depolarization?
Smallest vessels that exchange gases, such as oxygen and CO2, between the heart and the lungs and other vessels.
What are capillaries?
One of 4 mechanisms, other than the heart pumping, that helps move blood throughout the body.
What are sphincters (pre-capillary), contraction of the diaphragm, skeletal muscle contractions, and valves in the veins?
Blood arrives here after leaving the right ventricle.
What is the pulmonary artery or the lungs?
Outer layer of the heart. Not what the heart is encased in.
What is the epicardium?
The last sound of the Korotkoff sounds measures this.
Carry oxygen-rich blood back to the heart from the lungs.
What are pulmonary veins?
Controls blood flow from left atrium to left ventricle.
What is the mitral valve?
The last chamber oxygenated blood flows before going to the body.
What is the left ventricle?
These fibrous strands anchor the valves and prevent them from flipping.
What is the chordae tendineae?
Considered normal resting blood pressure. Need the measurement too.
What is 120/80 mmHg?
Largest artery in the body.
What is the aorta?
Coagulation of the blood can cause this visible change to the veins.
What are varicose veins?
Daily Double: Risk your points to win big!
Trace the full path of blood starting from the vena cava and ending at the aorta.
What is vena cava → right atrium → tricuspid valve → right ventricle → pulmonary valve → pulmonary artery → lungs → pulmonary veins → left atrium → bicuspid/mitral valve → left ventricle → aortic valve → aorta?
Name all three layers of the heart wall from innermost to outermost.
What are the endocardium, myocardium, and epicardium?
The ventricles contract during this phase of the cardiac cycle. `
What is systole?
The streching and closing of the blood vessel.
What is vasoconstriction?
The narrowing of the aorta that can slow down the rate of blood flow. Usually caused by the build up of plaque.
What is aortic stenosis?
