Torie Soriano Physiology Lab Report The Effects of Exercise on the Cardiovascular System Introduction Exercise has a major impact on the cardiovascular system and its efficiency in the human body. There are many concepts which need to be examined to understand exercise and the cardiovascular system‚ such as systolic and diastolic blood pressure‚ cardiac output‚ total peripheral resistance‚ and physiological pathways. According to the European Journal of Cardiovascular Prevention and Rehabilitation

Renin is secreted in the response to SNS stimulation by the Juxtaglomertular apparatus (JG apparatus). Renin converts angiotensinogen to angiotensin I which is then converted in the lungs into angiotensin II by angiotensin- converting enzymes (ACE). Angiotensin II‚ a vasoconstrictor causes an increase in SVR which immediately raise blood pressure and also stimulates the release of aldosterone from the adrenal cortex. Aldosterone provokes the retention

PG REVIEW HEART DISEASES IN PREGNANCY MODERATOR: PROF SUNIL AGARWAL STUDENT: ANKIT KUMAR SAHU INTRODUCTION Heart disease is the second most common cause of maternal death in Western countries‚ suicide being first1. According to CDC‚ heart disease is the leading cause of death in women who are 25 to 44 yrs old2. Maternal cardiac disease in a pregnant woman can present challenges in cardiovascular and maternal-fetal management thereby leading to significant non-obstetric

HYPONATRAEMIA IN THE NEUROSURGICAL PATIENT INTRODUCTION Sodium the most abundant electrolyte in the human body‚ and therefore the osmolality of body fluids is strongly dependent on its concentration. Osmolality in turn is important in maintaining homeostasis within the brain. Ironically‚ dysfunction of the brain can cause changes in sodium homeostasis. To avoid neurological deterioration‚ morbidity or mortality the sodium level must be corrected promptly. The two most common causes of hyponatraemia

Maternal mortality due to sepsis is worryingly increasing through developed and developing countries. This is despite a worldwide effort towards reducing maternal death‚ maternal sepsis during pregnancy remains one of the worlds leading causes of preventable maternal death. In developed countries 3% of all maternal mortality is due to sepsis‚ whilst that figure jumps to 12% in developing countries. Pregnancy affected by severe sepsis or septci shock‚ run the risk of pre-term labour‚ fetal infect
