Which gland produces a hormone that increases heart rate and blood pressure in times of stress?
Maternal fetal stress transfer Cortisol is type of hormone called a glucocorticoid, which glucose usage in the body and tends to be activated during a fight-or-flight response. Cortisol is produced in the adrenal gland, whose activity is mediated by the hypothalamus and pituitary glands of the brain. Together, the collective signaling of the hypothalamus, pituitary gland, and adrenal gland is known as the hypothalamo-pituitary-adrenal (HPA) axis. During a period of psychosocial stress, cortisol is released, leading to physiological manifestations of stress such as increased maternal blood pressure (MBP) and maternal heart rate (MHR). In the case of a pregnant woman, the release of cortisol
Rate pressure product Rate pressure product Pressure rate product, also known as Cardiovascular Product or Double Product, is used in cardiology and exercise physiology to determine the myocardial workload. Rate Pressure Product (RPP) = Heart Rate (HR) * Systolic Blood Pressure"' (SBP) with the units for the Heart Rate being "beats per minute" and for the Blood Pressure "mmHg". Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP). It will be a direct indication
