Q

What are memory cells

A

B cells that are activated if the body is exposed to the same pathogen a second time

17
Q

What are plasma cells?

A

B cells that multiply when they come in contact with pathogen; produce antibodies that attack the pathogen

18
Q

What are lymph nodes?

A

filters lymph and forms lymphocytes

19
Q

What are Killer T cells?

A

T cells that stop the spread of diseases within the body by releasing toxins to destroy abnormal and infected cells

20
Q

What are T cells?

A

lymphocyte produced and processed in the thymus gland; active part of the immune system

21
Q

What is systemic circulation?

A

continuous circulation of blood from the heart, to the body, and back to the heart

22
Q

What is pulmonary circulation?

A

continuous circulation of the blood from the heart, to the lungs, and back to the heart

23
Q

What are pulmonary veins?

A

blood vessels that carry oxygenated blood from the lungs to the left atrium of the heart

24
Q

What are pulmonary arteries?

A

blood vessels that carry deoxygenated blood from the right ventricle of the heart to the lungs

25
Q

What is the atrium?

A

a top chamber of the heart where blood flows into first

26
Q

What is a ventricle?

A

a bottom chamber of the heart squeezes blood out of the heart

27
Q

What is blood pressure? What is considered a normal BP?

A

the force of blood against the arterial walls. normal blood pressure is 120/80

28
Q

What is systolic blood pressure?

A

maximum arterial pressure during contraction of the left ventricle of the heart, the top number of a BP measurement

29
Q

What is diastolic blood pressure?

A

minimal arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood; the bottom number of a BP measurement

30
Q

What is sphygmonamometer

A

instrument for measuring blood pressure
