Question

select all that apply
choose all that are functions of the circulatory system.

□ regulation of body temperature
□ transportation of nutrients and gases
□ formation and elimination of urine
□ stabilization of body fluid ph

Explanation:

1. Regulation of body temperature: The circulatory system can dilate or constrict blood vessels to release or retain heat, so this is a function.
2. Transportation of nutrients and gases: Blood in the circulatory system carries nutrients (from digestive system) and gases (oxygen from lungs, carbon dioxide to lungs), so this is a key function.
3. Formation and elimination of urine: This is the function of the urinary system (kidneys, ureters, etc.), not the circulatory system.
4. Stabilization of body fluid pH: The circulatory system transports buffers and substances that help maintain pH balance in body fluids.

Answer:

• Regulation of body temperature
• Transportation of nutrients and gases
• Stabilization of body fluid pH
