The main artery supplying blood to the pelvis is called this.
What is the iliac artery?
Which heart valve prevents backflow from the pulmonary artery into the right ventricle?
Pulmonary valve
What is the purpose of the coronary circulation system?
Supplies oxygenated blood to the heart muscle itself
If the sinoatrial (SA) node fails, which structure typically takes over as the pacemaker?
Atrioventricular (AV) node
Which blood vessels connect arterioles and venules
Capillaries
When this heart valve does not close properly, blood can leak back into the left atrium
What is the mitral (bicuspid) valve?
This chamber of the heart has the thickest myocardium because it pumps blood to the entire body.
What is the left ventricle?
This genetic disorder prevents blood from clotting properly due to a lack of clotting factors.
What is hemophilia?
The two phases of the cardiac cycle are called these.
What are systole and diastole?
This two different arteries supplies blood to the brain, neck and spine.
Vertebral & Carotid Arteries
Why is dehydration dangerous for individuals with sickle cell trait?
It increases the risk of red blood cell sickling
This artery supplies blood to the front and bottom of the left ventricle and the front of the septum.
What is the left anterior descending (LAD) artery?
Which disorder is characterized by abnormally shaped red blood cells
Sickle cell disease
Which phase of the cardiac cycle occurs when the heart muscle relaxes?
Diastole
Which cardiovascular condition results from plaque buildup in the arteries?
Atherosclerosis
This structure separates the right and left ventricles.
What is the interventricular septum?
This node, also known as the heart’s pacemaker, initiates electrical impulses to regulate heart contractions.
What is the sinoatrial (SA) node?
Which structure transmits electrical impulses from the atria to the ventricles?
Bundle of His
This condition occurs when the blood has an abnormally low oxygen-carrying capacity.
What is anemia?
Which vitamins (3) are all necessary for red blood cell production?
Folate, vitamin B12 and iron
Write out the pathway of blood flow through the heart, starting from the superior/inferior vena cava and ending at the aorta.
What is: superior/inferior 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?
This genetic connective tissue disorder can lead to life-threatening aortic rupture and is often found in tall individuals with long limbs, scoliosis, and hypermobile joints.
What is Marfan’s Syndrome?
Name 4 Exercise Adaptations that can occur to the cardiovascular system in response to exercise?
- Increase Cardiac Output
- Increased Blood Volume
- Increased diameter of blood vessels
- Increase number of capillaries
- Increased cognitive function
- Increased motor skill/efficient movement
- Increased oxygen efficiency
- Increased size & # of mitochrondia
- Increased distribution of blood to active muscles
This artery branches off the right coronary artery (RCA) and supplies blood to the right ventricle, playing a key role in ensuring deoxygenated blood reaches the lungs.
What is the Right Marginal Artery (RMA)?
These specialized fibers spread electrical impulses through the ventricles, triggering a coordinated contraction that efficiently pumps blood to the lungs and body.
What are the Purkinje Fibers?
