55% of blood is made of this non-living material.

What is plasma?

100
This side of the heart pumps oxygen-poor blood through your pulmonary circuit.
What is the right side?
100
_____ carry blood away from the heart whereas _____ deliver blood back to the heart.
What are arteries & veins, respectively?
100
_____: the thin, whitish layer present at the erythrocyte-plasma junction.
What is the buffy coat?
100
_____: zipper-like dark-staining junctions that contain anchoring desmosomes and gap junctions.
What are intercalated disks?
200

This element is found in RBCs that make it possible to transport oxygen from the lungs to the tissues in your body.

What is iron (Fe) or the heme group?

200
The three layers of the heart.
What is the epicardium (visceral pericardium), myocardium, and endocardium?
200
Blood vessels differ in diameter and thickness, but most share the same 3 layers of coverings. Name the coverings from superficial to deep.
What is Tunica externa, Tunica media, Tunica intima?
200
_____: the protein that makes RBCs red, binds easily and reversibly to oxygen, and most oxygen carried in blood is bound to this protein.
What is hemoglobin?
200
_____: a graphic record of the heart's electrical activity.
What is an electrocardiogram (ECG/EKG)?
300

There are 3 major proteins in blood plasma. This protein is responsible for regulating osmotic pressure.

What is albumin?

300
This part of the heart's intrinsic conduction system is known as the "pace maker".
What is the SA (sinoatrial) node?
300
_____ arteries are conducting arteries _____ arteries are distributing arteries _____ are resistance arteries _____ are capacitance vessels
What is elastic, muscular, arterioles, and veins?
300
_____: this term refers to blood cell formation. Literally means "blood" "to make".
What is hematopoiesis?
300
_____: this blood vessel layer is made mostly of circularly arranged smooth muscle cells and sheets of elastin.
What is the Tunica media?
400

This enzyme converts fibrinogen to fibrin in the process of hemostasis.

What is thrombin?

400
This wave of an electrocardiogram tracing indicates when the atria depolarize prior to atrial systole.
What is the P wave?
400
True or False: Blood pressure falls from the arteriole end of a capillary bed to the venule end, whereas osmotic pressure remains the same.
What is True?
400
_____: means "lacking blood". A condition in which the blood's oxygen-carrying capacity is too low to support normal metabolism.
What is anemia?
400
_____: (also known as veins) can hold up to 65% of the body's blood supply at any time.
What are capacitance vessels OR blood reservoirs?
500

People with this blood type are known as universal donors.

What is Type O?

500
The _____ valves produce the "Lub" heart sound, while the _____ valves produce the "Dup" sound.
What are the Atrioventricular (AV) valves and Semilunar (SL) valves?
500
Blood flow (F) is a function of blood pressure gradient (Pi - Pf) and peripheral resistance (R). So, F = (Pi-Pf)/R. Resistance (R) is the opposition to flow. Name three important sources of resistance to blood flow.
What is blood viscosity, blood vessel length, and blood vessel diameter?
500
_____: a dense network of connective tissue fibers that reinforces the myocardium internally and anchors the cardiac muscle fibers.
What is the cardiac skeleton?
500
_____: the volume of blood flowing through a vessel, organ, or entire circulation in a given period (ml/min) _____: the force per unit area exerted on a vessel wall by the contained blood (mm Hg) _____: opposition to flow, the amount of friction blood encounters passing through a vessel
What is blood flow, blood pressure, & resistance?
