“Teach me,” she said.

[America]

my hands are icicles again. you should study arm and hand nervous anatomy real good and give me a magic bullet.

[Cecily]

I told you. Mirror boxes. Probably need one good arm though.

Already covered nervous/skeletal/muscular system last year, but that teacher sucked. Wait till I’m a psychiatric NP first and then I can tell you, “I’m sorry that’s not my area of expertise. Here’s a prescription for Zoloft.”

And Gmail is fucking up. Fantastic, that's where my lab reports are.

[Cecily]

Well, I'm screwed. This took a long time. 1/6 down. ~4 hours left.

Anatomy and physiology lab practical today... this is what I know besides structures:

Hemoglobin: 13-18g/ dl males, 12-16g/dl females
Hematocrit: 45-52% men, 37-48% women
Blood count: ~5million erythrocytes / cubic mm
White blood cell count: 7-11k normal, over is leukocytosis,inflamation possible infection. Under is Leukopenia suggests immune system disorder.
Men: 4.5-6m, women 4-5.5m
Blood glucose: 70-100 mg/dl

Pulse pressure: systolic - diastolic. 40-50mmhg
Mean arterial pressure: diastolic - (1/3 pulse pressure) 70-110 mmhg
<60 ischemic organs
Heart rate: 60-100, >100 tachycardia, <60 Bradycardia
O2%: 95-100%
Respiration rate: 12-20, 16/18 average
Minute ventilation rate: RR x TV = x ml
Tidal volume: volume of normal inhalation in/out cycle ~500ml
Expiratory reserve volume: Volume of forced exhalation after normal TV
Inspiratory reserve volume: volume of forced inhalation after normal TV,
IRV=VC-(ERV+TV)
Reserve volume: Air in lungs remaining after forced exhale, ~1000ml
Vital capacity: total volume of exchangeable air in lungs, VC=TV+IRV+ERV
Total lung capacity: TV+IRV+ERV+RV

Whole blood is 45% formed elements, 55% plasma
Plasma is 90%+ water, proteins (albumin 60%,globulins 36%, fibrinogen 4%), and other solutes (waste,02/CO2, hormones, electrolyte, something something)

EPNLMEB - formed element abundance

Erythrocytes - rbc
Platelets
Leukocytes
A. Granulocytes
1. Neutrophils - bacteria killers
2. Basophils - inflammatory responses, histamine/heparin release
3. Eosinophils - parasitic worm infections
B. Agranulocytes
1. Monocytes - phagocytosis - macrophages in tissue
2. Leukocytes - mount responsive to infection T/B cells

EKG
P-wave: atrial depolarization
QRS complex: ventricular depolarization, atrial repolarization obscured
T-wave: ventricular depolarization

Heart rate: 60 / #boxes R peak to R peak x.04
Need to learn interval times here

PR interval is begining of P to Q boxes x .04
Normal value = .16 to 18 seconds

QRS complex = Q to R boxes x .04
Normal value = .08 to .10 seconds

QT interval = Q to end of T x .04
Normal Value = .3 to .4 seconds

[Cecily]

That’s about everything. Hour left to study.

SA node to AV node to bundle of his to L/R bundle branches to purkinje fibers

PR interval is begining of P to Q boxes x .04
Normal value = .16 to 18 seconds

Longer suggests heart block

QRS complex = Q to R boxes x .04
Normal value = .08 to .10 seconds

Longer suggest r/l bundle branch block

QT interval = Q to end of T x .04
Normal Value = .3 to .4 seconds

Shorter with increased HR

H20+C02 <-> H2OCO3 <-> HCO3- + H+

Water combines with carbon dioxide to form carbonic acid, this reaction catalyzed by enzyme carbonic anhydrase carried in RBCs. CO2 diffuses into RBC -> gets turned to carbonic acid -> acid disassociates into bicarbonate ion and Hydrogen.

More hydrogen ions more acidic. More CO2 (hypoventilation) more hydrogen, more acidic, pH down. Vice versa.

Normal blood pH 7.4, 7.35 to 7.45
<7.35 acidosis >7.45 alkalosis

Diaphragm contracts, moves down. External intercostal contract, sternum / chest moves up and out. Volume in lungs increases, lowers pressure below atmospheric pressure and air moves down pressure gradient = inspiration.

Exspiration = diaphragm / intercostals relax. Chest moves down and pressure increases as volume decreases. Air in lungs higher pressure than atmosphere and moves down pressure gradient.

Normal blood pH 7.4, 7.35 to 7.45

But all those alkaline water people keep telling me that shit should be purple! Lol
