Question

ᴡʜᴀᴛ ɪs sᴇᴘᴛᴜᴍ ?????¿¿¿¿​

Answer 1

Step-by-step explanation:

The septum prevents mixing of blood between the two sides of the heart. ... ASDs and VSDs allow blood to pass from the left side of the heart to the right side. This means that oxygen-rich blood can mix with oxygen-poor blood. As a result, some oxygen-rich blood is pumped to the lungs instead of out to the body.

Answer 2

A septum (Latin for something that encloses; plural septa) is a wall, dividing a cavity or structure into smaller ones.
