Flashcards in Topic 12 - Circulatory Route Deck (30):
1

circulatory routes

closed, double circulation

closed = ?

 

blood confined to heart and blood vessels

2

circulatory routes

closed, double circulation

double = ?

2 routes (pulmonary + systemic)

3

Name the 3 types of circulations in the adult circulation

  1. pulmonary circulation
  2. systemic circulation
  3. coronary circulation (visible externally)

4

pulmonary circulation

step 1: 

right ventricle to lungs via pulmonary arteries (deoxy blood)

5

pulmonary circulation

step 1: right ventricle to lungs via pulmonary arteries (deoxy blood)

step 2: 

pick up oxygen in lungs via capillaries

6

pulmonary circulation

step 1: right ventricle to lungs via pulmonary arteries (deoxy blood)

step 2: pick up oxygen in lungs via capillaries

step 3:

lungs to left atria via pulmonary veins (oxygenated blood)

7

pulmonary circulation

starts at the: 

right ventricle (deoxy blood)

8

pulmonary circulation:

from the right ventricle to 

pulmonary arteries (deoxy blood)

9

pulmonary circulation:

from pulmonary arteries to

capillaries in respiratory portion of lungs (oxy blood)

10

pulmonary circulation:

from capillaries in respiratory portion of lungs to 

pulmonary veins (oxy blood)

11

pulmonary circulation:

from pulmonary veins to 

left atrium

12

Systemic circulation

step 1:

left ventricle to organs via aorta (oxygenated)

13

systemic circulation

step 1: left ventricle to organs via aorta (oxygenated)

step 2:

 

organs remove oxygen via capillaries

14

systemic circulation

step 1: left ventricle to organs via aorta (oxygenated)

step 2: organs remove oxygen via capillaries

step 3:

organs to right atrium via superior + inferior vena cava (deoxygenated)

15

overall route of systemic circulation

and name the subdivisions

cerebral = 

heptatic = 

coronary = 

left ventricle to right atrium = systemic circulation

subdivisions

cerebral = brain

heptatic = liver

coronary = heart

16

draw the coronary circulation

17

fetal circulation 

step 1:

fetus gets O2, nutrients from + expels wastes to mothers blood

18

fetal circulation 

step 1: fetus gets O2, from nutrients from + expels wastes to mother's blood

step 2:

  • exchange site in the placenta
    • blood supplies in close together, but do not mix

19

fetal circulation 

differences from adult circulation

  1. umbilicle vein...
  2. lungs + liver...
  3. umbilicle arteries...

 

  1. umbilicle vein (towards fetal heart)
  2. lungs + liver basically non-functional
  3. umbilicle arteries (away from fetal heart)

20

name the 3 main parts of the body that is different between the adult circulation and the fetal circulation

  1. umbilicle vein (towards the fetal heart)
  2. lungs + liver basically non functional
  3. umbilicle arteries (away from fetal heart)

21

fetal circulation: differences from adult circulation

umbilical vein (towards the fetal heart)

  • carries oxygenated blood from placenta to vena cava

22

fetal circulation: differences from adult circulation

lungs + liver basically non functional

  • 3 shunts to bypass (although some blood flow to these organs for nourishment/growth

23

fetal circulation: differences from adult circulation

lungs + liver basically non functional

i.

ii.

iii.

i. ductus venosus

ii. foramen ovale

iii. ductus arteriosus

24

fetal circulation: differences from adult circulation

lungs + liver basically non functional

ductus venosus

  • connects _________ (oxy or deoxy?) to __________ (oxy or deoxy?) to _______ liver

  • connects umbilical vein (oxy blood) to inferior vena cava (deoxy blood) to bypass iver 
    • permits most of the oxygenated blood coming from the placenta to bypass the liver 
  • oxy and deoxy blood mixes
  • mixed blood enters fetal heart via inferior vena cava

25

in the fetal circulation

mixed blood enters fetal heart via 

inferior vena cava

26

Fetal circulation: Differences from adult circulation: 

foramen ovale 

  • hole in where?
  • allows what?

  • hole in interatrial septum
  • allows blood to move from the right to left atrium (bypass lungs)

27

what allows blood to move from the right to the left?

a) ductus venosus

b) foramen ovale

c) ductus arteriosus

foramen ovale

28

Fetal circulation: Differences from adult circulation: 

ductus arteriosus

  • connects what?

connects pulmonary trunk + aorta (bypass lungs)

29

Fetal circulation: Differences from adult circulation: 

umbilical arteries (away from fetal heart)

  • returns what

returns mixed blood to placenta

30

what returns mixed blood to placenta?

a) umbilical veins

b) lungs and liver

c) umbilical arteries

d) ductus arteriosus

umbilical arteries
