 Hoe haal je adem?

Inademing:

Manier 1, ribademhaling /borst ademhaling

1. Tussen rip spieren trekken samen ribben kantelen omhoog
2. Borstkas wordt breder
3. Longen worden groter
4. Luchtdruk in de longen wordt kleiner
5. Lucht stroomt naar binnen: inademing

Manier 2, middenrifademhaling/buik ademhaling

1. Middenrifspieren trekken samen middenrif wordt platter
2. Borstkas wordt naar beneden toe groter
3. Longen worden groter
4. Luchtdruk in de longen wordt kleiner
5. Lucht stroomt naar binnen: inademing

Uitademing:

1. Tussen rip spieren ontspannen ribben zakken omlaag
2. Borstkas wordt smaller
3. Longen worden kleiner
4. Luchtdruk in de longen wordt groter
5. Lucht stroomt naar buiten: uitademing

Manier 2, middenrif ademhaling /buik ademhaling

Neus/mond keelholteluchtpijpbronchiënluchtpijptakjeslongblaasjes
luchtpijp=verstevigd met kraakbeenringen zodat die altijd open staat

2. Co² vanuit bloed naar lucht in de longblaasjes (deze uitwisseling heet gaswisseling)
