Question

which body system is not directly involved with helping to maintain blood pressure?
a endocrine system
b digestive system
c muscular system
d urinary system

Explanation:

• The endocrine system releases hormones (e.g., aldosterone) that can affect blood volume and vessel tone, influencing blood pressure.
• The muscular system (smooth muscle in blood vessels) can constrict or dilate vessels, directly impacting blood pressure.
• The urinary system regulates blood volume (by adjusting urine output), which is a key factor in blood pressure maintenance.
• The digestive system's main function is to break down food and absorb nutrients. While it has an indirect role in overall health (e.g., nutrient absorption for other systems), it is not directly involved in the immediate regulation of blood pressure.

Answer:

B. Digestive system
