Study Notes
Heart and Blood Vessels
- The heart is like a car engine, with valves and pressurized chambers, responsible for delivering blood and nutrients to organs.
- During acute stress, the heart rate and force of contraction increase, and blood vessels tighten to get blood and nutrients flowing faster.
- Constantly operating the heart in overdrive can be damaging.
Damaging Effects of Stress on the Heart
- Increased blood pressure leads to blood vessels distending and becoming more rigid, requiring more force from the heart to pump blood.
- This leads to a vicious cycle of elevated blood pressure, potentially causing hypertension (HTN).
- Hypertension can lead to vascular disease, where blood vessels experience damage, inflammation, and plaque buildup.
- Vascular disease in the coronary arteries can lead to coronary artery disease (CAD), heart attacks, and death.
Metabolism
- During stress, the body secretes hormones like cortisol and glucagon, converting stored energy into usable forms.
- If the extra energy is not used, it can exacerbate metabolic conditions like diabetes, leading to extra blood sugar.
- Extra blood sugar can contribute to cardiovascular disease.
Reproductive System
- Chronic stress can impede reproductive abilities, shutting down ovulation and uterine development in girls.
- Hormones involved in pregnancy, like LH and FSH, can become chronically inhibited, making it harder to release eggs or nurture their growth.
- Boys experience a similar inhibition of sex hormones, leading to reduced testosterone levels.
- Stress can cause erectile dysfunction (ED) in men due to reduced blood flow to the penis.
Immune System
- The immune system has two categories: innate (inflammation) and adaptive (specific white blood cells and antibodies).
- Acute stress can lead to overuse of the immune system, causing inflammation and attacking good things in the body.
- Chronic stress can suppress the immune system, making it less responsive to threats and increasing susceptibility to illness.
- Examples of suppressed immune system function include decreased wound healing and increased susceptibility to illness.
