These are red blood cells that carry the oxygen in the blood.
What are erythrocytes?
These cell fragments help prevent blood loss.
What are platelets?
Approximately this % of blood is composed of water.
What is 50%?
What is the aorta?
A normal blood pressure is read as 120 over 80. This number represents the diastolic pressure.
What is 80?
These are white blood cells that perform various defensive functions in the blood.
What are leukocytes?
These blood cells produce antibodies.
What are lymphocytes?
This blood type is considered to be the universal donor.
What is O-?
These are the only veins in the body that carry oxygenated blood.
What are the pulmonary veins?
This structure of the heart is known as the pacemaker.
What is the SA node?
(Or sinoatrial node)
This is the phase of the cardiac cycle in which the ventricles are relaxed.
What is the diastolic phase?
These cells carry oxygen in the blood.
What are erythrocytes?
This blood type contains no antibodies against A, B, or Rh antigens.
What is AB+?
What is the bicuspid valve?
(Or mitral valve, or left atrioventricular valve)
These chambers of the heart are contracting during the systolic phase.
What are the ventricles?
This is the phase of the cardiac cycle in which the ventricles contract.
What is the systolic phase?
These blood cells fight inflammation.
What are eosinophils?
Of the following chemicals, which exist only when the blood coagulation process is occurring?
factor IX, activated factor XII, fibrinogen, calcium ions, thrombin, fibrin
What are activated factor XII, thrombin, and fibrin?
This chamber of the heart is the first to receive deoxygenated blood from the body.
What is the right atrium?
These valves are open during the diastolic phase.
What are the atrioventricular valves?
(Or tricuspid and bicuspid)
This is the process by which the formed elements of blood are made in the body.
What is hemopoiesis?
These blood cells release histamine and heparin.
What are basophils?
If prothrombinase is present in an area of a blood vessel, which stage of hemostasis is taking place?
What is the blood coagulation phase?
(Third Stage)
These 'strings' connect the papillary muscles to the atrioventricular valves, allowing them to open during the diastolic phase.
What are chordae tendinae?
If this valve did not open properly, blood would not exit the left ventricle properly.
What is the aortic semilunar valve?
