Title :

Regulation of human body temperatureLoss of heat through sweat production : Heat loss

measured at fingertips

Equipment Setup

1. The Discovery is connected to the serial port of the computer2. The Discovery was turned on3. The temperature is connected to the 1/0 port and 1/0 2 port of the Discovery4. The humidity sensor is connected to 1/0 3 of the discovery5. The Discovery is set up

a. Input 1: Temperature (-10500)b. Input 3: Humidityc. Rate: 1/secd. Sample: 2000

Experiment Procedure :

1) Attach a temperature sensor to the fingers of your right arm, as demonstrated infigure.

2) Start the discovery either from the discovery panel or from discover the IT software :click the run button on the left tool bar.

3) Follow temperature changes in your fingertip, register on your computer monitor, tillit stabilizes about 5 minutes.

4) Cover the hand holding the temperature sensor, with a plastic bag.5) Place inside the bag a humidity sensor and an additional temperature sensor.6) Tie the bag covering your hand, to prevent air flow into and out of the bag.7) Follow changes in humidity and temperature inside the bag, for about 10 minutes.8) Remove the plastic bag from your hand. Follow changes in the humidity and

temperature inside the plastic as well as the temperature of your fingertip, for

additional 5 minutes.

Discussion

Experiment conducted to study the relationship between body temperature and

humidity. Based on the data and the graph obtained, we can see that for the first 400 seconds,

temperature is higher than humidity. This is the time when hand is still not covered with

plastic bag, so the temperature follows the normal body temperature. After the hand is

covered with plastic bag, the temperature and the humidity are both rises. When high

temperatures are combined with high humidity, it feels very warm.

The temperature increase because the air is trapped inside the plastic bag causing the

environment now is warm in the plastic bag. High temperature in the plastic bag causes

humidity to increase. The body senses changes in the environment and responds by makingchanges in functions. We know that the hypothalamus in the brain can act as a thermostat and

control the bodys functioning to regulate temperature to keep us from overheating or getting

too cold. The hypothalamus causes changes in the size of blood vessels in the skin, which

then has a direct impact on the amount of heat lost or retained by the body. Then, our heart

rate and pulse rate increase and our hand start to sweat. Sweating is the process to cool down

our body.

The last 5 minutes, the hand is uncovered. We can see from the graph, temperature is

now rising while humidity is decreasing. At this stage, our body temperature is returned to

normal. When there is no sweat produced, humidity is low.

Conclusion

Humidity decrease when temperature increases.
