her heart beat fast,and the blood warmed,and relaxed every inch of her bod

问题描述:

her heart beat fast,and the blood warmed,and relaxed every inch of her bod
这一句中,and the blood warmed,and relaxed every inch of her body,可以按独立主格理解吗?但是我觉得如果是独立主格应该在her heart beat fast后不加and.如果加了and,我觉得就成了两个句子,

首先beat这个词就应该用beats,因为heart是单数.
显然这里不是独立主格结构,因为有连词and,所以后面是一个句子.我觉得这句应该这么理
her heart beats fast,她的心跳得很快,
and the blood warmed,and relaxed every inch of her body.血流温暖了她的身体,让她的每一寸肌肤都感到放松.(blood是主语,warm 和relax 都是谓语)
