PHYS TEST 3

What are the blood components of an average man or woman:
volume?
formed elements?
plasma?

Women: 5Liters Men: 5.5Liters
Women:42% Men: 45%
Plasma: 58% Men: 55%

________stimulates red blood cell development.

Testosterone

Components of Plasma?

91% water
1.1% organic compounds (glucose)
0.9% salt (NaCl and small others)

What are the three types of plasma proteins?

Albumins (60%)
Globulins (36%)
Fibrinogen (4%)

What are the jobs of the plasma proteins?

Albumin:
1) transport materials: Bilirubin, Bile Salts, and Penicillin
2) provide 60% of the PCOP
GLOBULINS:
1) alpha and beta: clotting and transport (lipids, fat-soluble vitamins, thyroid hormones, cholesterol, and iron)
2) gamma: immune response

Where is Cl- concentration highest and lowest in terms of the plasma

lowest: in vena cava----most is in red blood cell

highest: aorta---most in plasma as RBC is O2 rich

A left shift in the Oxyhemoglobin Dissociation Curve promotes O2

LOADING

A right shift in the Oxyhemoglobin Dissociation Curve promotes O2

UNLOADING

At the same percent saturation the left shift has a _____PO2

lower

At the same PO2 the left shift has a _____ percent saturation.

higher

At the same percent saturation the right shift has a _____PO2

higher

At the same PO2 the right shift has a _____ percent saturation.

lower

What is the Bohr effect?

high CO2 causes O2 unloading

What is the Haldane Effect?

high O2 causes CO2 unloading

What is the relationship of the Oxyhemoglobin curve between mother and fetus?

Fetus--shifted left
momma--shifted right

Which way does exercise shift the curve?

Right---oxygen unloading

Which way does an increase in CO2 shift the curve?

right

Which way does an decrease in H+ ions shift the curve

left

which way does an increase in H+ ions shift the curve

right

Which way does a decrease in temperature shift the curve?

left

Which way does an increase in temperature shift the curve?

right

What directly competes with oxygen and what indirectly competes with oxygen

Carbon monoxide directly competes with oxygen

Carbon Dioxide indirectly competes with oxygen

What Controls Respiration?

1) Medulla Oblongata: respiratory center, has cardiovascular and respiratory center together to coordinate
2) Cerebral Overides: CNS computer overrides (central/higher thinker) can tell medulla what to do)
3) Herring-Brever Reflex: alveoli stretch regul

Where will blood plasma have the highest/lowest concentration of Cl-?

highest----arteries O2 rich blood

lowest-----vena cava more CO2 so more Cl- exchange.

A left shift in the Oxyhemoglobin curve promotes O2 _______.

Loading

A right shift in the Oxyhemoglobin curve promotes O2

Unloading

Describe the relationship of Oxyhb curves of a mother and her fetus

FETUS----Left shift---loading

Momma---Right shift---unloading

A left shift at the same PO2 will have a ________ % saturation.

higher

A left shift at the same % saturation will have a _____ PO2.

lower

A right shift at the same PO2 will have a _____ % saturation.

lower

A right shift at the same % saturation will have a _____ PO2.

higher

An increase in CO2 will shift the curve _____.

right

A decrease in CO2 will shift the curve_______.

left

An increase in hydrogen protons will shift the curve ______.

right

What is the Bohr effect?

high CO2 causes O2 unloading

What is the Haldane Effect

High O2 causes CO2 unloading
