Pulmonary ventilation

(breathing) is the proses by which air is moved into and out of the lungs.

Anatomi:

2. Internal Respirasi.

150 CC a. Tranportasi (sirkulasi).

b. Buffer

Inspirasi is an active process in which the diaphragm and the external intercostal muscles increase the dimensions, and thus the volume, of the thoracic cage.

This decreases the pressure in the lungs and draws air in.

Tekanan alveoli minus

3 s/d 10 mmHg < dari

760 mmHg.

• Normal expiration is the passive process.

• The inspiratory muscle relax and the elastic tissue of the lungs recoils, returning the thoracic cage to its smaller, normal dimensions.

• This increases the presure in the lungs and forces air out.

 Forced or labored inspiration and expiration are active proceses, dependent on muscle actions.

 Aktif inspirasi dibantu otototot: Scalani, Sterno cledo mastoideus, pektoralis, membantu angkat sternum dan costae ke depan atas.

Tekanan alveoli turun sampai 100-80 mmHg.

 Aktif ekspirasi dibantu otototot : Abdominalis,

Pumpa jantung

Agar darah sampai pada sel

Tubuh harus dipompa jantung

Menuju jaringan, termasuk

Jaringan jantung sendiri.

Jumlah darah yang dipompa jantung dipengaruhi:

Strooke vulume dan frekuensi

Denyut jantung per menit.

Makin tinggi strooke vulumee

Dan frekuensi makin tingg COP

Tetapi makin tinggi frekuensi

Jantung makin sedikit aliran

Koroner yang memberi nutresi

Jantung.

Efisiensi kerja jantung.

Makin kuat dan fleksibel otot

Jantung , strooke volume

Makin besar dan makin hemat energi kerja jantung

Sehingga frekuensi jantung

Permenit makin kecil.

Termasuk tahanan perifer

Sistem sirkulasi

Tahanan perifer meliputi:

1. Vulume pembuluh darah

2. Vikositas darah
