These blood cells transport oxygen throughout the body using hemoglobin.

What are erythrocytes (RBCs)?

100

This chamber receives oxygenated blood returning from the lungs.

What is the left atrium?

100
This vein is the largest in the body
What is the vena cava?
100

This structure is known as the natural pacemaker of the heart.

What is the sinoatrial (SA) node?

100

Ms. Sam has been practicing OT for this many years

What is 10 years

200

This blood type is considered the universal red blood cell donor because it lacks A, B, and Rh(D) antigens.

What is O negative?

200

This valve prevents blood from flowing backward from the aorta into the left ventricle.

What is the aortic semilunar valve

200

These structures found in many veins prevent blood from flowing backward, particularly in the lower extremities.

What are venous valves?

200

This wave on an electrocardiogram represents atrial depolarization.

What is the P wave?

200

This is Ms. Sam's favorite color

What is green

300

This type of white blood cell is the most abundant and is typically the first to respond to bacterial infections.

What are neutrophils?

300

This phase of the cardiac cycle occurs when the ventricles relax and fill with blood.

What is ventricular diastole?

300

What vessels provides blood supply to a developing fetus?

What are the umbilical veins and umbilical arteries?

300

This structure briefly delays electrical impulses before they travel into the ventricles, allowing time for ventricular filling.

What is the atrioventricular (AV) node?

300

Ms. Sam prefers this taste of food

What is sweet

400

This component of blood is part of its liquid portion rather than one of its formed elements

What is plasma?

400

This valve is commonly called the bicuspid valve

What is the mitral valve?

400

Atherosclerosis, smoking, and increased blood viscosity are all contributing factors to the increase in this process

What is peripheral artery resistance?

400

This ECG complex represents ventricular depolarization.

What is the QRS complex?

400

Ms. Sam attended this University

What is Texas Tech or Midwestern

500

The process of forming new blood is

What is hemopoiesis

500

A blockage in these blood vessels can deprive the myocardium of oxygen, potentially causing a myocardial infarction.

What are the coronary arteries?

500

This layer of a blood vessel contains smooth muscle and controls vasoconstriction and vasodilation.

What is the tunica media?

500

This part of the heart's conduction system carries the electrical current back up the ventricles.

What are the Purkinje fibers?

500

This is the age of Ms. Sam's daughter

What is 15 months
