Question

homeostasis disturbed by decreasing body temperature below 36.7ºc; body’s temperature sensors; information affects; thermoregulatory center in brain (hypothalamus); sends commands to; respond with blood vessels and sweat glands in skin; decreased blood flow to skin; shivering; homeostasis restored by increasing body temperature; normal body temperature

Explanation:

To solve the problem of filling in the blanks in the body temperature regulation (homeostasis) flowchart, we analyze each component:

1. First Purple Box (Detecting Temperature Change)

The body’s temperature sensors (like thermoreceptors in skin and organs) detect when body temperature drops below 36.7°C. So this box should be “Detect (or Sense) body temperature below 36.7°C”.

2. Blue Box (Thermoregulatory Center Input)

The “Body’s temperature sensors” send information to the thermoregulatory center (hypothalamus in the brain). So this box is “Send information to thermoregulatory center”.

3. Light Blue Box (Hypothalamus Role)

The hypothalamus acts as the control center for thermoregulation. So this box is “Control Center (Hypothalamus)”.

4. Teal Box (Response to Low Temp)

To raise body temperature when it’s too low, the body reduces heat loss (decreased blood flow to skin) and increases heat production (shivering, which involves muscle contractions). So this box is “Increased heat production (via shivering/muscle activity)”.

5. Green Box (Blood Vessels/Sweat Glands Response)

When temperature is low, blood vessels in the skin constrict (narrow) to reduce heat loss, and sweat glands decrease sweating (or stop sweating) to prevent cooling. So this box is “Constrict blood vessels; Decrease sweating”.

6. Final Teal Box (Restoring Normal Temp)

The combined responses (constriction, shivering, reduced sweating) increase body temperature back to normal (36.7°C), restoring homeostasis. So this box is “Body temperature increases to normal (36.7°C)”.

These steps follow the feedback loop of homeostasis: Stimulus (low temp) → Receptor (temperature sensors) → Control Center (hypothalamus) → Effectors (blood vessels, muscles, sweat glands) → Response (raise temp) → Homeostasis restored.
