16
Q

Higher blood pressure (hypertension) results from:

A

Stress, drugs, obesity, clogs, nicotine, alcohol

17
Q

Homeostasis

A

Body’s optimal levels

18
Q

Embolus

A

Moving blood clot

19
Q

Thrombus

A

Clot now plugging a vessel

20
Q

Heart attack and stroke

A

Aneurysm. Clotting of heart and clotting of brain

21
Q

Platelets hold

A

Thromboplastin. Release when they burst

22
Q

Plasma proteins

A

Albumin (draw water back into blood vessels), Globulin (provides protection against microbes in immune response), and Fibrinogen (clotting cascade).

23
Q

Thalassemia

A

Abnormally shapes hemoglobin

24
Q

Nodes

A

SA, then AV, then purkinje fibres.

25
Q

Donating based on Rhesus Factor

A

Everything ok except Rh+ to Rh-

26
Q

T cells “trained” in:

A

Thymus (and partially tonsils)

27
Q

Spleen

A

Blood reservoir, lymph filter site, etc

28
Q

Blood pressure measured in

A

Millimeter of mercury

29
Q

Cardiac output

A

Heart rate * stroke volume

30
Q

Blood percentages

A

55% plasma (water, proteins, nutrients, etc)
4% Buffy coat (platelets and WBC)
41% RBC

31
Q

Clotting cascade

A

Thromboplastin + calcium = prothrombin
Fibrinogen + prothrombin = fibrin (thread) and thrombin (sticky)
Mesh over wound
RBCs and platelets stick and clot

32
Q

WBC types

A

Agranulocytes (no specs in cytoplasm, Lymphocytes and Monocytes) 30% And Granulocytes (specs, Neutrophils [suicide sacs] and Baso/Eosinophils) 70%

33
Q

Angglutination

A

Clotting of blood because of antibodies

34
Q

Brain systems

A

Automatic system and Somatic. AS goes into Sympathetic (response) and ParaS (return back to normal)

35
Q

ECF

A

Extra cellular fluid
