<prompt> Fana ka kakaretso ea mosebetsi oa pelo.nan  <response>: Instruction in English: Provide an overview of the function of the heart. . Response in English: The heart is a vital organ in the human body that serves as a pump to circulate blood throughout the body. It is responsible for delivering oxygen, nutrients, and other essential substances to cells, tissues, and organs, and for removing waste products and carbon dioxide. The heart consists of four chambers - two atria and two ventricles. Deoxygenated blood from the body returns to the right atrium and passes into the right ventricle, which then pumps it through the lungs to be oxygenated. Oxygenated blood then returns to the left atrium, where it passes into the left ventricle and is pumped out to the rest of the body. The hearts rhythm and rate are regulated by electrical impulses controlled by the sinoatrial node and the atrioventricular node, and the heart contracts and relaxes to pump blood in a continuous cycle. Overall, the heart plays a crucial role in maintaining homeostasis and supporting life-sustaining processes in the body. . Response in Sesotho: Pelo ke setho sa bohlokoa meleng oa motho se sebetsang e le pompo ho potoloha mali ho pholletsa le mele. E na le boikarabelo ba ho isa oksijene, limatlafatsi le lintho tse ling tsa bohlokoa liseleng, lisele le litho tsa mele, le ho tlosa litšila le carbon dioxide. Pelo e na le likamore tse nè - atria tse peli le li-ventricle tse peli. Mali a se nang oxygen e tsoang meleng a khutlela atrium e nepahetseng me a fetela ka hara ventricle e nepahetseng, ebe e a pompa ka matšoafong hore a fumane oksijene. Joale mali a nang le oksijene a khutlela atrium e ka letsohong le letšehali, moo a fetelang ka ventricle e ka letsohong le letšehali me a pompeloa mele oohle. Moribo le lebelo la pelo li laoloa ke matla a motlakase a laoloang ke node ea sinoatrial le node ea atrioventricular, me pelo ea honyela le ho phomola ho pompa mali ka potoloho e tsoelang pele. Ka kakaretso, pelo e bapala karolo ea bohlokoa ho boloka homeostasis le ho tsehetsa litsebetso tse bolokang bophelo meleng.
