???What involuntary muscles of the body helps control breathing, blood pressures, and digestion?
It is actually the Autonomic Nervous System(ANS) that controls all these actions like breathing, blood pressure, etc.What involuntary muscles of the body helps control breathing, blood pressures, and digestion?
Smooth muscle
There a involuntary muscles present in the respiratory tract e.g. trachea and bronchi that control the respiration..That's the reason its difficulty to breathe in asthma where there is severe contraction of these muscles...
Blood pressure is controlled by contraction and relaxation of smooth muscles in the blood vessels...contraction raises the blood pressure where as relaxation lowers it...
The involuntary muscles of respiratory system do not directly control the digestion...Rather they contract and relax rhythmically (peristalsis) to push the food down the digestive tract...
But all these muscles are under the control of Nervous System...
diaphragm?
