Body Temp

Question 0

Cell respiration also produces what as one of its energy products

Answer 0

Heat

Question 1

What is the process that releases energy from food to produce ATP

Answer 1

Cell respiration

Question 2

What factors affect cell respiration

Answer 2

The hormone pyroxene produced by the thyroid gland increases the rate so respiration and heat production

And stress situations epinephrine and norepinephrine first created by the adrenal Medela and the sympathetic nervous system becomes more active. Epinephrine increases the rate of cell respiration. The increased production of ATP increases heat

Organs that are normally active and produce ATP our sources of heat when the body is at rest. Example: skeletal muscles.

The liver also produces ATP and 20% of the total body at rest.

The intake of food increases heat production.

Changes in body temperature affect metabolic rate and heat production.

Question 3

What are the pathways of heat loss from the body

Answer 3

Skin, respiratory tract, urinary and digestive tracts

Question 4

What determines the amount of heat that is lost through the skin

Answer 4

The amount of blood flow and activity of sweat glands

Question 5

What processes influence blood flow through the skin and heat lost

Answer 5

Radiation, conduction, convection

Question 6

What does radiation mean

Answer 6

Heat from the body is transferred to cooler objects not touching the skin

Question 7

What is conduction

Answer 7

Loss of heat cooler air or objects such as clothing that touch the skin.

Question 8

What is convection

Answer 8

Air currents move the warmer air away from the skin surface and facilitate the loss of heat; this is why a fan makes us feel cooler on hot days

Question 9

Why does a cool day that is windy feel colder than a cool day that the air is still

Answer 9

Because the wind blows the slightly warmer air surrounding the body away replacing it with colder air

Question 10

What constricts or dilates to decrease or increase bloodflow in the skin

Answer 10

Arterioles in the dermis

Question 11

What glands secrete sweat

Answer 11

Eccrine sweat glands

Question 12

What is the most important regulator of day today metabolism, increases use of foods for ATP production, and increases heat production

Answer 12

Thyroxine

Question 13

What is important interested tuitions, increases metabolic activity of many organs and increases ATP and heat production

Answer 13

Epinephrine and sympathetic stimulation

Question 14

What factor as normal muscle tone and requires ATP, the heat produced is about 25% of the total body heat at rest

Answer 14

Skeletal muscles

Question 15

What factor is always metabolically active produces as much as 20% of total body heat at rest

Answer 15

Liver

Question 16

What factor increases activity of the G.I. tract and increases ATP and heat production

Answer 16

Food intake

Question 17

What factor increases metabolic rate which increases he production which further increases metabolic rate and he production and may become detrimental during high fevers

Answer 17

Higher body temperature

Question 18

How is heat lost from the respiratory tract

Answer 18

Heat is lost from the respiratory tract As the warmth of the respiratory mucosa evaporates some water from the living epithelial surface
The water be performed is exhaled any small amount of he is lost

Question 19

Why does a dog pant

Answer 19

They don’t have many sweat glands and panting is the rapid movement of air into and out of the upper respiratory passages where the warm surfaces evaporate large amounts of water. In this way the animal may lose large amount of heat

Question 20

What is responsible for the regulation of body temperature and is considered thermostat of the body

Answer 20

Hypothalamus

Question 21

What inside the hypothalamus the text changes in the temperature of the blood that flows to the brain

Answer 21

Specialized neurons

Question 22

What in the skin provides information about the external temperature changes to which the body is exposed

Answer 22

Temperature receptors
