modifications to it. The BiopacPro program was used to monitor a volunteer’s blood pressure; while PhysioEx was again used to monitor the modifications to it. Heart rate was shown to decrease as temperature decreases‚ increase in the presence of epinephrine‚ and fluctuate with addition of various ions. It was also found that increased pressure and blood vessel diameter result in increased blood flow. Introduction In humans‚ the pumping of blood is essential to life. A consistent blood flow is

Unit 2: The Psychology of Fitness Assignment 1: The Body’s Response to Acute Exercise Introduction: As a health and fitness instructor I need to be able to apply my anatomical and physiological knowledge to practical activities and exercises. I have conducted practical assessments to explore how the body responds to physical activity and exercise. I have then written a report‚ including all the anatomical and physiological changes that occur within each of the bodily systems. Acute exercises

Epistaxis‚ a common condition in all age groups‚ has a bimodal distribution with 2 peaks: under the age of 10 years and in the 60s [1]. Sixty percent of people probably experience epistaxis once in their life [2]. Although epistaxis may occur secondary to surgery‚ trauma‚ hypertension‚ bleeding disorders‚ hereditary hemorrhagic telangiectasia‚ and antiplatelet and anticoagulation drug use‚ its etiology is unknown in 70% to 80% of cases [3]. Epistaxis is usually self-limiting but can be life threatening

Describe the preoperative and postoperative care of a client having PTCA/cardiac cath. What complications can occur post cardiac cath? The goal of PCI (percutaneous Transluminal intervention) is to open the blockage in the coronary artery. By opening the area that is blocked‚ it will help to reperfuse the myocardium. The faster this is done will help

Lower levels of the neurotransmitter serotonin are connected to bulimia‚ depression and food disorders; lower levels of nor epinephrine was found on anorexic patients. It is possible that abnormal levels of the nor epinephrine neurotransmitter could cause weight loss on anorexic patients. These are some examples that support the scientific researches.

Neurogenic Shock Neurogenic shock is a type of shock that is caused by a spinal cord injury that affects important nerves in the nervous system. Injury to the nervous system causes the walls of blood vessels to relax‚ which increases the blood pressure. Neurogenic shock mainly affects the spinal cord. The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. Neurogenic shock occurs when a spinal cord injury happens‚ particularly involving

When substances like acetylcholine and norepinephrine are released in the body‚ they tend to bind to receptors‚ tissues and neurons. These neurotransmitters transfer signals throughout the nervous system and stimulates action potentials in the postganglionic neurons. Receptors found on the ANS and PNS includes the cholinergic receptors‚ which consists of all sympathetic and parasympathetic preganglionic‚ sympathetic postganglionic and all parasympathetic postganglionic neurons. The cholinergic receptors

Anxiety and depression can be very similar. One of the main reasons why anxiety and depression are similar are because of neurotransmitters such as dopamine‚ epinephrine and serotonin. The most important of these neurotransmitters is serotonin‚ it is a neurotransmitter responsible for maintaining mood balance‚ appetite‚ sleep patterns‚ memory‚ temperature regulation‚ learning‚ social behavior‚ and sexual desire. Serotonin can also affect the muscles‚ endocrine system‚ and cardiovascular system and
