Control of respiratory processes is similar to control of cardiovascular in that . . . a. norepinephrine on alpha receptors caus
es bronchoconstriction b. epinephrine on beta 2 receptors causes bronchodilation c. somatic motor neurons release acetylcholine onto nicotinic receptors at ganglionic synapse d. alveolar radius can be regulated similar to capillary radius
b. epinephrine on beta 2 receptors causes bronchodilation
Explanation:
This is because epinephrine is an hormone and neurotransmitter that stimulate beta 2 receptors which causes signaling and their in presence in airway smooth muscle causes bronchodilation, which counter the activation of the M3 muscarinic receptors in cardiovascular. When stimulate in skeletal muscles it can lead to increased contractility and also to muscle tremors.
