Final answer:
Smooth muscle is located in the bronchioles, digestive tract, and blood vessels. It has no striations, is involuntary, and each cell has a single nucleus and is tapered at both ends.
Step-by-step explanation:
The location of smooth muscle in the body includes the following areas:
Bronchioles: Smooth muscle tissue is found in the respiratory tract, which includes the bronchioles.
Digestive tract: This type of muscle is present in the walls of hollow organs such as the intestines and stomach.
Blood vessels: Smooth muscle is also found in the walls of passageways such as arteries and veins of the circulatory system.
Smooth muscle is characterized by its lack of striations, its involuntary control, having only one nucleus per cell, and cells that are tapered at both ends. It is different from cardiac muscle, which is found in the heart, and skeletal muscle, such as the pectoralis major muscle, which are both under voluntary control.
