Thermoregulation

What is the process by which the body maintains a stable internal environment despite changes in the external environment?

• Hemostasis

• Hypostasis

• Heterostasis

• Homeostasis

What is the term for the widening of blood vessels near the body surface, resulting in increased blood flow and heat loss?

• thrombosis

• hypertension

• vasoconstriction

• vasodilation

What is the term for the narrowing of blood vessels near the body surface, resulting in decreased blood flow and heat conservation?

• arteriosclerosis

• hypertension

• vasoconstriction

• vasodilation

What is the process by which the body releases moisture through the skin to cool down?

• Evaporation

• Perspiration or sweating

• Condensation

• Dehydration

What is the involuntary muscle contraction that generates heat to warm the body?

• Spasming

• Twitching

• Quivering

• Shivering

What are the specialized nerve cells that detect changes in temperature and send signals to the brain?

• Thermoreceptors

• Thermometers

• Temperature detectors

• Heat sensors

How does the body respond to high temperatures in order to maintain homeostasis?

• By increasing sweat production, dilating blood vessels near the skin's surface, and increasing breathing rate.

• By increasing body temperature even further

• By decreasing breathing rate and shivering

• By decreasing sweat production and constricting blood vessels near the skin's surface

How does the body respond to low temperatures in order to maintain homeostasis?

• Dilating blood vessels, sweating, and decreasing metabolic rate

• Relaxing muscles, increasing blood flow, and decreasing heart rate

• Expanding blood vessels, panting, and decreasing shivering

• Constricting blood vessels, shivering, and increasing metabolic rate

Which part of the brain is responsible for regulating body temperature?

• Occipital lobe

• Cerebellum

• Frontal lobe

• Hypothalamus

What are the different ways in which the body loses heat?

• Compression, expansion, and condensation

• Insulation, absorption, and reflection

• Ingestion, digestion, and excretion

• Radiation, conduction, convection, and evaporation
