Dive Synthesis

The results obtained from the experiment appear trustworthy and make sense. The results, data, from the experiment show that jumping jacks were the most effective exercise when increasing the heart rate, whereas the resting heart rate is the lowest. The average resting heart rate was 53.33bpm whereas the average heart rate after jumping jacks was 113.33bpm. The average heart rate after jumping jacks was 113.33bpm and 90bpm in trial 2, causing it to be 60pm higher that the average resting heart rate in the first trial. This makes the results from the experiment trustworthy because it shows that the calculation of the heart rates were correct because there was a large difference.

For example, for a voluntary reaction the body must listen to the sound so the brain has to process the sound then is signaled to kick. For an involuntary reaction, the process is faster because its automatic and the brain doesn’t have to process the signals. 2. Suggest two ways that relax reactions help maintain homeostasis in the human body. When we relax, we maintain steady breathing levels so relax reactions help maintain homeostasis in the human body by maintaining steady

1. Describe the relationship between intrapulmonary pressure, atmospheric pressure, and air flow during normal inspiration and expiration, referring to Boyle’s law. - Boyles law states that as the pressure of gas increases then the volume of gas decreases. Which is how intrapulmonary and atmospheric pressure are connected to one another. Intrapulmonary pressure is lower while undergoing inspiration and higher than atmospheric pressure during the time of expiration.

The temperature of the solutions could also have played a factor in the Daphnia Heart rate as ideal conditions for Daphnia is 68 degrees Fahrenheit and the temperature of the solutions was not measured for.

This condition arises because of the small amount of space the whales are given to swim in and because of their unnatural diet of thawed

The same worm (for a control variable) was placed in a forty percent mixture of Pau D’Arco (independent variable) and water for ninety seconds. Then, the worm’s heart rate (dependant variable) was recorded as before on a slide with beats per thirty seconds. As a result, the hypothesis

Darwin evolutionary theory has changed the scientific explanations about how organisms can adapt to extreme environments and survive. Through scientific experiments and analysis, scientists learn what kinds of adaptations allow a specific organism to survive and thrive in an extreme environment. These adaptations can be categorized into chemical functions and structural anatomy. These adaptations are present in deep-sea creatures and are what allows them to survive in extreme environments. Giant Squid, a database, and Deep-Sea Vents, an informational article by Amy Bliss, describe the anatomical adaptations that allow giant squids and yeti crabs to survive in extreme environments.

Many people are scared of scuba diving because it’s something different, but once you get over the original fears of going underwater for a long period of time you become

1. Provide at least two examples of the opposite effects of the sympathetic and parasympathetic divisions of the nervous system. Parasympathic divisions slows the heart rate and breathing in someones body and the sympathy makes these functions work. 2. Explain how the respiratory and the cardiovascular system work together to meet the demands of the working muscle.

It contains veins that help maintain its body temperature. As orcas live in waters of zero degrees Celsius and less, it is important that they maintain their internal body temperature. When swimming at high speeds, the dorsal fin helps keep the killer whale stable but it is not essential for

Unconditioned response = The audience will respond with an accelerated heartbeat as they will feel nervous and frightened by the screams and blood. Conditioned Response = Now that the audience has begun associating the gloved hand with a woman’s scream and the sight of blood, they will feel the accelerated heart beat and sweaty palms.

When the time for our pool class came I could not back down, so the first thing I did when I entered the pool was to dunk my head in the water and wet my face, to which I received a mouthful of chlorinated water. As I spat it out, I was unsure whether I should even try swimming with my head underwater or if I should continue with my previous technique. I decided to plow on since I had already mentally prepared. As I did, I practiced taking 3 strokes then coming up for a breath of air like the instructor had told me the previous week. While doing this, I felt myself propel through the water faster than ever before, and I felt less fatigued too, likely because this form was more aerodynamic and I no longer had to swim with extra weight since human heads naturally float [1].

Thus, the sympathetic nervous system increases heart rate, and the forced contractions widen the airways making it easier to breathe. Your body now releases stored energy, which allows for increased strength in muscles, and can also cause your palms to sweat, pupils to dilate, and hair to stand up. The parasympathetic division is most active during resting conditions, hence, why it can also be called, “rest and digest”. This division controls body processes during ordinary situations. It generally slows down your heart rate and decreases your blood

The forced swimming test evaluates the possibility of rodents to escape from an uncomfortable situation. This test can be used in preclinical studies to measure the effectiveness of antidepressants (Porsolt et al., 2001). Based on this, Lucky et al (1997) have set up some parameters in the FST, and thus one can distinguish two types of escape behavior during the forced swim test behavior; are horizontal movements while swimming and climbing, which are vertical movements with the legs directed from the

The Skin Structure and Function: The skin is the largest organ. It covers the whole body and is water-resistant. The skin consists of two layers; the Epidermis and Dermis (under which lies the subcutaneous or fatty layer).
