Homeostasis (3)

Biology

Not quite remember

I easily remember

Regulation of body temperature by effectors through physical methods by arterioles (1)

Arterioles in the skin dilate (vasodilation) to allow more blood to flow to the skin surface

Regulation of body temperature by effectors through physical methods by arterioles (2)

More heat is lost to the external environment through radiation

Regulation of body temperature by effectors through physical methods by skeletal muscles (1)

Skeletal muscles contract and relax less

Regulation of body temperature by effectors through physical methods by skeletal muscles (2)

The body does not shiver

Regulation of body temperature by effectors through physical methods by the sweat glands (1)

The sweat glands are stimulated to produce more sweat

Regulation of body temperature by effectors through physical methods by the sweat glands (2)

Heat is absorbed to evaporate sweat, and this cools the skin

Regulation of body temperature by effectors through physical methods by the adrenal glands (2)

The adrenal glands are less stimulated to secrete adrenaline

Regulation of body temperature by effectors through physical methods by the adrenal glands (2)

Metabolic rate decreases

Regulation of body temperature by effectors through physical methods by the thyroid glands (1)

The thyroid gland is not stimulated and the secretion of thyroxine is reduced

Regulation of body temperature by effectors through physical methods by the thyroid glands (2)

Metabolic rate decreases and no excess heat is generated
