Term
Erythrocyte
Definition
Make up 99% of formed material in the blood; carries oxygen; limited metabolism
Term
Hemoglobin
Definition
responsible for carrying oxygen
Term
Five types / Fuctions of leukocytes?
Definition
(granulocyte) Neutrophil: fight infections by phagocytosis
Basophil: increase inflammation and prevents blood clots
Eosinophil: decrease inflammation
(agranulocyte) Lymphocyte: produce antibodies
Monocyte: destroy invading organisms and foreign material by phagocytosis
Term
Embolus
Definition
blood clot that moves through blood stream
Term
Thrombus
Definition
blood plug
Term
3 stages of hemostasis
Definition
Vasoconstrictive: blood vessel constricting
Platelet plug: stop blood from leaking
Coagulation
Term
Stages of Coagulation
Definition
Tissue or blood vessel damage produces
- prothrombinase
Prothrombinase converts prothrombine into
-thrombine
Thrombine converts fibrinogen into
- fibrin
Term
Universal blood donor? Why is this so special?
Definition
Type O Blood. Has neither A nor B antigens, so nothing will fight against it.
Term
Type A Blood
Definition
A antigen; Antibody against B antigen
Term
Type B Blood
Definition
B Antigen; Antibody against A antigen
Term
Type AB blood
Definition
A & B antigen / no antibody
Term
Type O Blood
Definition
No antigens; Antibody against A & B antigens
Term
Universal Recipient? Why so special?
Definition
Type AB+ Blood; Can handle positive and negative Rh antigens.
Term
Rh antigen?
Definition
First found in the Rhesus monkey; most important blood antigen
Term
What do antigens do?
Definition
Triggers the production of antibodies
Term
Two divisions of circulation
Definition
Pulmonary circulation: circulation of blood over the air sacs of the lungs
Systemic circulation: circulation of blood through the other tissues of the body
Term
Cardiac cycle phases
Definition
Systolic phase: ventricles contract
Diastolic phase: ventricles relax
Cardiac cycle: complete round of systole and diastole
Term
"Lub-Dubb" sound of the heart
Definition
"lub" - atrioventricular valves closing
"dubb" - semilunar valves closing
Term
Systolic pressure?
Definition
Pressure in the aorta when ventricles contract
Term
Diastolic pressure
Definition
minimum pressure in the aorta
Term
Labeling terms and functions
Definition
Superior vena cava:

Pulmonary Semilunar Valve:

right atrium:

right atrioventricular canal:

right atrioventricular valve: regulates how blood flows thru the canal

chordae tendineae:

right ventricle: pumps blood into the pulmonary trunk

papillary muscles: contract when ventricles contract; keeps the valve from blowing out into the atrium

interventricular septum: separates the right and left ventricles

aorta:

pulmonary trunk:

Left atrium:

Left atrioventricular canal:

left atrioventricular valve: lets blood flow from the atrium, down the left AC, and into the left ventricle

aortic semilunar valve: separates the aorta and pulmonary trunk

left ventricle: empties into the aorta
Term
Flow of blood through the heart
Definition
Goes through the right atrium via the super vena cava, inferior vena cava, and the coronary sinus, into the right ventricle, out the pulmonary trunk to the bodies tissues and is deoxygenated, it goes through the pulmonary arteries to be deoxygenated before entering back in through the pulmonary veins, through the left atrium, into the left ventricle, through and out the aorta.
