Where are striated muscles located?
A. Stomach wall and uterus
B. Urinary bladder and intestine
C. Ciliary body of the eye D. Heart and skeletal muscles - (ANSWER)D. the stomach wall,
uterus, urinary bladder, intestine, and ciliary body all have smooth muscles


2.The pressure in the systemic arteries during ventricular contraction is?
A. Diastolic blood pressure
B. Osmotic pressure

blood pressure?
A. Sympathetic nervous system
