Vasoconstriction

relay this information to the control centre which send signals to effectors. For example if the body temperature has decreased effectors such as skeletal muscle will be stimulated causing shivering and blood flow will be restricted caused by vasoconstriction.(Waugh, Grant, 2014)…

Gasoline engines help us in many ways in modern time. They provide us with transportation, which is one of our most important aspects of gasoline engines. Gasoline engines are also used in many tools that we use to do many things today that make things a lot easier than doing it by hand. But there are negative effects that gasoline engines have on people and the Earth. An effect from GEE (gasoline engine emissions) is the increase of red blood cells. This is caused by exposure to 13-107 ppm…

contractions of the atria. Hypothesis It is expected that the beat period, r-pulse interval, and pulse amplitude will be affected by both exercise and after cold conditions have been applied. The cold conditions will slow the heart rate due to vasoconstriction, so the beat period will lengthen resulting in a longer r-pulse interval, as well as a decrease in pulse amplitude. . After exercise however, there will be an increase in blood heart rate due to vasodilation. This will cause the beat…

Measures and Apparatus Stress mindset. Stress mindset is measured before and after the video training using the SMM (Crum et al., 2013). Participants rate 8 items on a 0-4 Likert scale, with sample items such as “experiencing stress improves my health and vitality”. Negative items are reversed scored and the average of all items is computed. Scores higher than 2 indicate a stress-is-enhancing mindset (Appendix A). Neuroendocrine measure: cortisol. Sample of saliva will be collect using the…

Case Study 5 – AB As discussed in case 3, septic shock results from widespread inflammation and vasodilation in response to an infection. Norepinephrine is useful in septic shock because it increases afterload to maintain adequate tissue perfusion (De Becker et al., 2012). Dobutamine is an inotropic drug used in septic shock as it stimulates myocardial beta-adrenergic receptors thus increasing cardiac output by increasing contractility and heart rate (Dellinger et al., 2013; Enrico et al.,…

Respiratory Failure Respiratory failure is a deterioration of the gas exchange function of the lungs (Hinkle & Cheever, 2014). The lungs are not able to provide adequate oxygenation or ventilation for the blood. Respiratory failure is caused by impaired ventilation or perfusion mechanism in the lungs. Colon Cancer Colon cancer arises from the epithelial lining of the intestine. It may start as a benign polyp and become malignant. “It will invade and destroy normal tissue and extend into…

Na+/K+ Pump and the Secondary Active Transport of Glucose The concentration gradient of sodium ions produced by the sodium potassium pump possesses potential energy that is utilized as sodium ions move down the concentration gradient during secondary transport. [5]. The sodium gradient propels the absorption of glucose in the glucose sodium cotransporter, SGLT1 [6]. SGLT1 uses the sodium gradient to move the glucose molecule down the gradient since it does not have its own energy to do so [6].…

The differential diagnoses include COPD (emphysema, cor pulmonale,) and possible stage I hypertension. 4. My diagnosis for Mason is pulmonary emphysema, which is an obstructive disease characterized by the enlargement of airways beyond the terminal bronchioles with destruction of alveolar walls resulting in loss of elastic recoil and airflow limitation. Cigarette smoking is the main cause of pulmonary emphysema with signs and symptoms, including dyspnea on exertion, cough with scant mucus,…

Homeostasis is defined as the means by which the internal atmosphere of the human body remains balanced regardless of the numerous changes within the environment (Mastrangelo, 2013). One of the most remarkable attributes of homeostatic control is body temperature regulation. Thermoregulation is controlled by the autonomic nervous system (ANS), which is a vastly complex, multifaceted neural system that sustains the internal homeostasis of the human body (Chawla, 2013). Within the ANS, is the…

The scientific term which is used to describe the temperature control in the body is called hypothalamus. Hypothalamus begins in your brain since your brain makes the choices for your body. This is very important because if you're too cold you can start shivering for long periods of time which can lead up to hypothermia. On the other hand, if you are too hot you and start to sweat a lot it can lead up to avoid disease. Here are the 3 different that your body can make in these tough situations.…
