Beta-I receptors (B1) are a type of adrenergic receptors that increases CO by increasing heart rate and force of contraction; releases renin from kidneys.

Beta-II receptors (B2) are a type of adrenergic receptors. Smooth muscle relaxation or inhibition of smooth muscle contraction = promotes bronchodilation.
