Blood
These blood cells transport oxygen throughout the body using hemoglobin.
What are erythrocytes (RBCs)?
This chamber receives oxygenated blood returning from the lungs.
What is the left atrium?
This structure is known as the natural pacemaker of the heart.
What is the sinoatrial (SA) node?
Ms. Sam has been practicing OT for this many years
What is 10 years
This blood type is considered the universal red blood cell donor because it lacks A, B, and Rh(D) antigens.
What is O negative?
This valve prevents blood from flowing backward from the aorta into the left ventricle.
What is the aortic semilunar valve
These structures found in many veins prevent blood from flowing backward, particularly in the lower extremities.
What are venous valves?
This wave on an electrocardiogram represents atrial depolarization.
What is the P wave?
This is Ms. Sam's favorite color
What is green
This type of white blood cell is the most abundant and is typically the first to respond to bacterial infections.
What are neutrophils?
This phase of the cardiac cycle occurs when the ventricles relax and fill with blood.
What is ventricular diastole?
What vessels provides blood supply to a developing fetus?
What are the umbilical veins and umbilical arteries?
This structure briefly delays electrical impulses before they travel into the ventricles, allowing time for ventricular filling.
What is the atrioventricular (AV) node?
Ms. Sam prefers this taste of food
What is sweet
This component of blood is part of its liquid portion rather than one of its formed elements
What is plasma?
This valve is commonly called the bicuspid valve
What is the mitral valve?
Atherosclerosis, smoking, and increased blood viscosity are all contributing factors to the increase in this process
What is peripheral artery resistance?
This ECG complex represents ventricular depolarization.
What is the QRS complex?
Ms. Sam attended this University
What is Texas Tech or Midwestern
The process of forming new blood is
What is hemopoiesis
A blockage in these blood vessels can deprive the myocardium of oxygen, potentially causing a myocardial infarction.
What are the coronary arteries?
This layer of a blood vessel contains smooth muscle and controls vasoconstriction and vasodilation.
What is the tunica media?
This part of the heart's conduction system carries the electrical current back up the ventricles.
What are the Purkinje fibers?
This is the age of Ms. Sam's daughter
What is 15 months
