Question

Hi, I'm having trouble with this question, if anyone knows the answer, plz help!


Which of the following describes what might happen if the septum in the heart ruptured?

1) Blood from outside the heart would leak into the heart.

2)Blood entering the atria would leak into the ventricles.

3) Oxygenated and deoxygenated blood would mix in the heart.

4) Incoming and outgoing blood would mix, causing turbulence.

Answer 1

I would say between 1 and 2 but I'm not sure e.e

Answer 2

I am gonna go with number 2

Answer 3

what are you thinking @xxxFatimahxxx

Answer 4

I was thinking 3

Answer 5

well all blood is oxygenated hun

Answer 6

it all goes through the lungs and gets oxygen into the blood stream, just some oxygen is new and some isn't. the blood on the right is older oxygen and the left is newer oxygen, but it all has oxygen in it, so it wouldn't be 3

Answer 7

what are u thinking?

Answer 8

this is why I thought it was 3

Answer 9

oh i see, well once it reaches the heart, it gets new oxygen, and then it becomes oxygen rich.

Answer 10

3 is correct. One side of the heart handles "oxygenated" blood and the other side handles "deoxygenated" blood. The septum is between the two ventricles and if it ruptured then the blood that has come back from the lungs "oxygenated would mix with blood coming back from the body "deoxygenated"

Answer 11

1,2,4 can be ruled out because of the anatomical location of the septum.

1 the septum is located on the inside of the heart, not the outside wall.

2 the atria are separated from the ventricles by the atrioventricular (AV) valves

4 incoming blood enters the right atrium, outgoing blood leaves from the left ventricle; these are not separated distinctly by the septum.

Hope this helps

Answer 12

Oh, and to further clarify 3: deoxygenated blood returns to the heart through the right atrium and is pumped to the lungs through the right ventricle; the right side of the heart deals with deoxygenated blood.

Oxygenated blood returns to the heart through the left atrium, and is pumped out into systemic circulation by the left ventricle.

If the septum were ruptured, deoxygenated blood from the right ventricle would mix with oxygenated blood from the left ventricle
