Personal Statement What aspirations, experiences, or relationships have motivated you to pursue the study of medicine and the Joint Admission Medical Program? Please explain why or how. * (5000 characters) My interest in medicine sparked when I was an adolescent being cared for by my pediatrician, Dr. Gonzalez. As a kid, I consistently had shortness of breath and wheezing during sports competitions. As a result, Dr. Gonzalez diagnosed me with asthma and prescribed an inhaler and nebulizer to…

Strategies to prevent heart disease Heart disease is a devastating condition. It is known to be one of the leading causes of death across the world. There are some risk factors which make you more exposed to get a heart disease. Broadly, there are two types of risks: modifiable risk factors – the ones you can control such as diet, weight, lifestyle; and non-modifiable risk factors - ones you can’t control, like genetics. However, the good news is that your choices can control your heart health.…

RESEARCH DEMYSTIFIES HOW STRESS INCREASES THE RISK OF HEART DISEASE AND STROKE Topic: Research demystifies how stress increases the risk of heart disease and stroke Purpose: To find out if there is a connection between stress and cardiovascular disease. Hypothesis: The author’s hypothesis is that since previous studies has concluded that there is a link between stress and higher activity in the bone marrow and arteries in animals, the same could apply to humans. The author…

Blood pressure is the pressure applied by blood on the walls of blood vessels, it is controlled by a negative feedback system where heart rate and blood volume need to be altered in order to control the pressure. Local negative feedback systems and heart rate is regulated but the cardiovascular centre which also in turn controls neural and hormonal mechanisms. Neurons regulate heart rate and contractility and some neurons inhibit, stimulate or control heart rate by causing constriction which…

A polygraph is a common instrument of measurement to calculate and document physiological aspects such as respiration rate, electrodermal activity, and heart rate. The relevant uses of measuring respiration rate as well as heart rate are quite common in a wide variety of applications. However, electrodermal activity and the galvanic skin response are not commonly measured things in places such as the medical field, or education. Electrodermal activity (EDA) refers to the variation of the…

hold on high school teenagers and could stay with them as they move into adult hood. The everyday pressures that teens face cause insecurities in both girls and boys.

Teens are struggling with their body image, Teens see themselves as less valuable due to the desire to fit in, and teens face academic pressure creating an insecurities. Both adelesent girls and boys struggle with their self image, and…

Rate and Blood Pressure I. Introduction It is known that exercise effects how quickly a heart beats and thus how much pressure is needed to pump a person’s blood through their veins. There have been several studies over the years that have tested this. An experiment recoded by Nicolas Tordi, Laurent Mourot, Eglantine Colin, and Jaques Regnard, compared several factors between interval exercise and constant exercise. Two of the factors they monitored were heart rate and blood pressure. The…

The first two words that come to mind when someone says the word, “teenagers” are rebellious and awkward. Although it is stereotypical, is it true? Based on the teenagers in the world today, I think it is probably true. However, with all pressures from school, parents, peers, and health it is no wonder that teenagers today are striving to be more independent and self-reliant; although this may come across as being rebellious and awkward. But can they be blamed? I think not. With how we’ve…

Similar aspects of the endocrine and nervous systems are also located within major arteries, responding to changes in the cardiovascular system during hypovolemic shock. When baroreceptors sense there has been a fluid loss and that blood pressure has decreased, a “sympathetic response” throughout the body where nerve impulses cause the heart rate to increase to attempt to compensate for a decrease in oxygen circulating throughout the body (Tortura 782). An increase in the heart also causes…

Bladder Tissue Type: The bladder is a muscular pouch that holds urine. In the bladder, there is transitional epithelial tissue. This type of tissue has several layers and they can vary in appearance. It looks like a bunch of cubes squished together. The cells vary when they become more stretched. This also allows for contraction and expansion of the bladder. If the tissue did not perform these functions, then our bladder would rupture. The urine would then seep out into our body and cause a…
