experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable for both the control and experimental treatment was temperature. In the control treatment‚

hormones that cause certain responses within the body leading to the flight or fight situation. As with any function of the body there are impairment that are always possible as well. Knowing in advance what types of things can impair one ’s thermoregulation process gives people a step up against having issues later in life. The nervous system consists of two parts‚ the central nervous system (CNS) and the peripheral nervous system (PNS) (National Institute of Health [NIH]‚ 2013). Each part plays

Title Experimentation of Metabolic Rate on Gromphadorhina portentosa Ectotherms in Changing Temperatures Abstract Temperature and environment plays a key role on the effects of an ectothermic organism’s metabolism. The specific ectothermic organism used in this study was the Gromphadorhina portentosa also known as the Madagascar Hissing Cockroach. In this study we measured CO2 production (%) and temperature (̊C) every three minutes for a total of 15 minutes in three different temperature environments

Sea Otter Metabolics and Thermoregulation Sea Otters (Enhydra lutris) have always intrigued me because they are one of the most recent additions to the marine environment having only been fully aquatic for about 1-3 million years‚ but what really peaked my interest was the fact that they maintain homeostasis as far north as Alaska without blubber in 13-17 degree water‚ and that the metabolic rate that they would have to have must be enormous so I decided to look into what it takes to keep an

secreted by the sweat glands in the skin of mammals. Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body. In humans‚ sweating is primarily a means of thermoregulation which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2-4 liters per hour or 10-14 liters per day‚ but is less in children prior to puberty. Evaporation of sweat from the skin surface

Homeostasis is the ability to maintain a stable environment inside the body. For example‚ your body does things to maintain constant blood sugar levels and body temperature. 1.

The process in which several body systems work together to maintain the balanced environment is called homeostasis. The endocrine and nervous system work closely together to help maintain homeostasis. Examples of where they work together are thermoregulation and osmoregulation. [1] The nervous system is the body’s prime communication and coordination network and is constantly alive with electricity. The nervous system comprises of three systems‚ which are defined by anatomy and function. The three

The Effects of Temperature‚ Acetylcholine‚ and Adrenaline on the Heart Rate of Daphnia magna Hieu Duong 6 April 2011 Introduction The heart is a muscular organ that constantly pumps blood throughout the human body. The continuous flow of blood creates a system for vital organs within the body to gain oxygen and nutrients. The timely delivery of oxygen to the body’s organs is very crucial. Brain cells‚ for example‚ will die within minutes if the flow of oxygen is obstructed. For the

All thermoregulation mechanisms are designed to return the body to homeostasis. 4The hypothalamus is in the brain and is directly responsible for the core temperature and nerve impulses for the receptors in the skin. This allows the brain to get quick and direct

Introduction: The regulation of body temperature is called thermo-regulation. It is the ability of any organism to maintain the temperature of its body at normal level even when the temperature of the external environment is fluctuating. The normal temperature of the body of humans is approximately 37◦C or between the 98◦F-100◦F and it is called its core body temperature. This core temperature usually remains the same within a very short range of variations. This core temperature only
