От каких органов несет кровь питательные вещества и кислород к клеткам?

Ответы

Автор ответа: John0021

Главным насосом, двигающим кровь по сосудам, является сердце. Оно гонит обогащенную питательными веществами и кислородом кровь по артериям к каждой клеточке, где происходят обменные процессы: клетки получают питательные вещества и отдают отработанный материал для того, чтобы он был выведен из организма.
