    Katika sura hii, utachunguza pampu ya ajabu ambayo inahamasisha damu ndani ya vyombo. Moyo hufanya kazi kama “pampu mara mbili,” tangu contraction yake yanaendelea shinikizo linalojitokeza damu ndani ya vyombo vikuu kwa mzunguko mbili tofauti za mtiririko wa damu: damu kutoka upande wa kushoto wa moyo inapita ndani ya aorta kwa mzunguko wa utaratibu na damu kutoka upande wa kulia wa moyo inapita ndani ya shina la mapafu kwa mzunguko wa pulmona. Kutoka kwa vyombo hivi, damu inasambazwa kwa salio la mwili. Ingawa ufafanuzi wa neno “pampu” unaonyesha kifaa cha mitambo kilichofanywa kwa chuma na plastiki, muundo wa anatomical ni misuli hai, ya kisasa. Unaposoma sura hii, jaribu kuweka dhana hizi za mapacha katika akili: pampu na misuli. (Thumbnail picha mikopo: “Binadamu Heart Nje” na Tomáš Kebert & umimeto.org ni leseni chini ya CC BY-SA 4.0)
