let 's define ourselves some sets . so let 's say the set a is composed of the numbers 1 . 3 . 5 , 7 , and 18 . let 's say that the set b -- let me do this in a different color -- let 's say that the set b is composed of 1 , 7 , and 18 . and let 's say that the set c is composed of 18 , 7 , 1 , and 19 . now what i want... | so we actually can write that b is a subset -- and this is a notation right over here , this is a subset -- b is a subset of a . b is a subset . so let me write that down . | does it hold true that if a and b are sets , and b is a strict subset of a , then b can not be equal nor equivalent to a ? |

let 's define ourselves some sets . so let 's say the set a is composed of the numbers 1 . 3 . 5 , 7 , and 18 . let 's say that the set b -- let me do this in a different color -- let 's say that the set b is composed of 1 , 7 , and 18 . and let 's say that the set c is composed of 18 , 7 , 1 , and 19 . now what i want... | so , for example , we can write that a is a subset of a . in fact , every set is a subset of itself , because every one of its members is a member of a . we can not write that a is a strict subset of a . | is one significantly more common than the other ? |
what you 're looking at is the fetal heart . it looks a lot like the adult heart , but a couple of interesting differences that we 're going to go over . the first thing i want you to notice is that it 's mostly got what i 've drawn is kind of this purplish blood . in the adult heart we know there 's a real clear disti... | and so this hole -- let me take my finger out of here now -- this hole is called the foramen ovale . let me actually just label that for you , or foramen ovale . so the foramen ovale is this hole . so instead of calling it hole , you can now call it by its full name . | how long after birth does the foramen ovale remain operative ? |
