Thermoregulation

Water is one of the most important and essential fluid to our human body. We use and drink water almost 24 hours a day and 365 days a year, however, many of us probably have never thought of and find out what are the chemical and scientific reasons behind the importance of water. Approximately 50-65% of the average adult human body is water, however, this varies based on a number of factors such as age, health, weight and sex. In males, it is normally about 60% of the body weight. In…

fitness your horse is currently at. During exercise, warming up and cooling down are very important. During your warm up, the horse’s muscles will loosen up and this is when they work best. During your cool down, you are allowing the horse’s thermoregulation to get a head start to getting rid of the excess heat and relieve the horse of any future soreness. The amount of exercise and work needs to be taken into account as well, if you try to do extra exercise in one session, you are actually…

Human evolution is the time by which humans change overtime. Humans develop characteristics and traits that enhance their abilities and chances for survival. Physical and behavior traits have been shown to have some relations with the common ancestors of apes. While human evolution occurs it coexists with the study of population genetics. Population genetics occurs when frequencies in alleles between populations are distributed. Plenty of researchers have used these two ideas to study how…

become thinner, and the skin may become transparent and lose its elasticity, its mostly can be found in the older patient. The integument (of skin provides several important functions, namely protection from external environmental influences, thermoregulation, electrolyte balance and sensation – pain, touch, heat and cold. The skin comprises three major layers – the dermis, the epidermis and the subcutaneous fatty layer (containing the major nerves and blood vessels). As we age, the layers of…

release heat, however, it is easier for them to absorb. For example polar bears. Polar bears have a lot of fur; their fur is about two and a half to five centimetres (one to two inches) thick. A polar bears’ process of regulation of blood is called thermoregulation. Polar bears are well insulated so they tend to absorb heat very quickly. That is why polar bears move slowly and rest time to time to avoid overheating. When overheating occurs excess heat is released from the areas of the body…

A group of biologists have developed a general model to explain growth and development in ectothermic organisms. Changes in environmental temperatures effect the rates of most biological reactions and biological processes in ectotherms. The rates of ontogenetic growth and development are no exceptions. Ectothermic animals develop faster at warmer temperatures and they usually mature at smaller body sizes. This phenomenon has been called the temperature size rule (Zuo et Al. 2011). The…

Contractions Cease When a patient presents with preterm labor symptoms, the nurse will have to be prepared to perform assessments and diagnostics. The patient has not received any prenatal care, meaning she may not be knowledgeable of the dangers and symptoms of preterm labor, including what to do if preterm labor arises. The nurse will need to assess the patient’s psychosocial and emotional status, as this can cause effects on the fetus and outcome of preterm labor. (Lowdermilk, Perry, &…

mice is usually bred as a mutant type considering the sparse way of catching it in nature. Being a furred mammal, it has hair all over at different lengths and fibers to aid in keeping a sustainable environment (Dry 1926). Most of the adaptive thermoregulation in a mouse takes place in brown adipose tissue (Gray et al. 2002). This rodent is an endotherm. Endotherms are known for maintaining a constant, within narrow range, internal environment, unrelatedly to their external environment. That is…

1. The three major layers that make up the skin are the epidermis (made of epithelial tissue; provides a waterproof coating for the skin), the dermis (made of dense connective tissue; contains collagen and elastin fibers, blood vessels, nerve endings sweat glands, sebaceous glands, hair follicles, and more), and the hypodermis (made of areolar connective tissue and adipose tissue; this layer of subcutaneous fat provides padding and insulation for the body). 2. There are two main categories…

Maverick Wagner Evolution 2/20/15 Evolution of the Great White Shark Did you know that sharks appeared in the fossil record about 450 million years ago? The great white shark is one of many different species of cartilaginous fish out. There are approximately 350 species of sharks worldwide. The great white has become one of the most feared predators in the sea leaving the question as to how it achieved this success. The great white is about four to six meters in length and can weigh…
