Question 1

by the time blood reaches the venules and veins, the pressure is ______

Answer 1

less than 10 mmHg

Question 2

pressure in the thoracic Vena Cava and right Atrium

Answer 2

0 mmHg

Question 3

which veins are less comliance and why?

Answer 3

less compliance- in the limbs, bcs their walls are thicker

Question 4

how much of the blood does the veins contain?

Answer 4

~65%

Question 5

describe what does Cardiac function curve means

Answer 5

high venous return -> high right atrial pressure -> higher EDV -> higher CO

Question 6

describe what does vascular function curve means

Answer 6

driving force for blood is pressure difference!

if atrial pressure increase -> venous return decreases -> CO also decreases

Question 7

Lymphatic system job

Answer 7

responsible for returning interstitial fluids and proteins to the vascular compartment of blood

*lipids from GI travel through lymphatic system using chylomicrons

Question 8

how much lymph is produced?

Answer 8

120 mL/hour

Question 9

defifintion of Edema

Answer 9

increase in interstitial fluid volume

• increased filtration
• lymph drainage is impared

Question 10

by the time blood reaches the venules and veins, pressure is less then

Answer 10

10 mmHg

Question 11

Hydrostatic P in the thoracic vena cava and right atrium is also called

Answer 11

central venous pressure

Question 12

what does the capacitance of the veins allows us?

Answer 12

able to adjust blood volume returning to the heart (preload) based on the needs of the body
