Thermoregulation

Thermoregulation and reproduction are energetically costly events that many mammals face. To combat these obstacles, animals have developed the use of seasonally induced torpor and reproductive periods. Both of these events are usually initiated through a predictable environmental factor, primarily photoperiod. These two systems are usually mutually exclusive, but in Sminthopsis macroura, an Australian marsupial that reproduces in the winter, they can overlap since females with torpor being used…

The paragraph draws a conclusion that the fine lines discovered in a fossil skeleton did not certify that Sinosauropteryx was a feathered dinosaur. Whereas, the lecture rebuts this statement, and manifests that Sinosauropteryx has feathers. To begin with, the paragraph asserts that the fine lines were the fibers decomposed from skin preserved in the fossil instead of functional structures. Contrary to the reading, the lecture refutes that the fine lines are indeed functional structures,…

but it is under control by the thermoregulatory center which can be found in the hypothalamus (Rizzo the part of the brain that controls secretion from the pituitary gland (2006 p. 485)) which apprehend information from two fixed thermoregulation receptors (needed for the body to make its appropriate adjustment). The main purpose of these receptors is to find out someone’s temperature of their blood, which it travels through the brain and skin to oversees their external temperature. For…

different tissue types play a key role in how the human body responds to changes in temperature. The human body is complex and consists of several levels of organization (Ireland, 2013, p. 21). The process of homeostasis, homeostatic mechanism, and thermoregulation all intertwine to correctively maintain body temperature. Keywords: Homeostasis Our body “contains proteins, lipids, carbohydrates, nucleic acids, DNA and RNA” (Ireland, 2013, p. 18), and the body is only capable of maintaining a…

Psoriasis is a noncontagious, chronic, inflammatory disorder. Patients with psoriasis inherit a genetic predisposition for the disease which can sit dormant in the body. After major stress to the body or immune system the disease can be triggered. Often choosing to manifest on the elbows, knees, and scalp. There are 7 different classification of psoriasis. Plaque Psoriasis which is the most common type is causes large red scaly, inflamed patches usually on the elbows, scalp, and the lumbar…

Also known as the thoracic diaphragm. Thermoregulation Thermoregulation is the process that allows the body’s temperature to stay the same, it is like having an internal thermometer. A part of it is called Vasodilation is the widening of blood vessels by relaxing it makes it go to the surface of the body…

release more water in urine. Nausea, dizziness and lose consciousness are caused by consuming alcohol. The high water temperatures can elevate the body temperature of the internal organs beyond safe limits. To maintain the body homeostasis, the thermoregulation mechanism which controlled by the hypothalamus and anterior pituitary gland could join in to lower the body temperature by opening the sweat glands or increasing the heat exchange. The opening of the sweat gland causes the water to lose…

The cardiovascular system The cardiovascular system consists of the heart, blood vessels and approximately the 5 litres of the blood that the blood vessels transport. The cardiovascular system is powered by the body’s hardest working organ. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from your body. The main structures of this system is the heart the blood vessels and blood. Delivery of oxygen and nutrients The pulmonary circuit carries blood…

“Nutritional blood flow through the active skeletal muscles rises by 10-20-fold from its resting value of 2-5ml/min/100g.” (Clifford and Hellsten 2004, p 72) The skin in conjunction to this has a vital role. One of the skins many functions is thermoregulation. Thermoregulation allows the body to maintain a stable body temperature. “The dermis has nerve endings called thermoreceptors that transmit signals to the brain and then the brain sends signals back to the dermal blood vessels.” (Saladin,…

escribe the precautions and personal protective equipment required to care for this patient. Patient should be placed on Transmission-Based isolation. "Droplet transmission occurs when the pathogen travels in water droplet expelled as infected person exhales, coughs, sneeze, or talks."(pg. 608 Treas). " Droplet can spread by direct spread with mucous membranes or indirect contact touching bedside table that was containment with most droplets then rubbing your eye."(pg. 623 Treas). "Standard…
