Study Notes
Symptoms Experienced by Mio
- Experienced sudden dizziness and near-fainting.
Blood Pressure in Supine Position
- Blood pressure in the supine position was measured but specific value not provided.
Medications Discontinued
- Certain medications in Mio's treatment plan were stopped, although specifics are unspecified.
Regulation of Blood Flow to the Skin
- Regulation of blood flow to the skin involves thermoregulation and nutrient delivery.
Influences on Cardiovascular Function
- Cardiovascular function is influenced by physical activity, hormonal changes, and neural regulation.
Cardiovascular Responses to Exercise
- Responses are achieved via increased heart rate, stroke volume, and redistribution of blood flow.
Primary Function of Capillaries
- Capillaries facilitate the exchange of nutrients, gases, and wastes between blood and tissues.
Formula for Mean Arterial Pressure (MAP)
- MAP can be calculated using the formula: MAP = Diastolic BP + 1/3(Systolic BP - Diastolic BP).
Purpose of the Lymphatic System
- The lymphatic system is responsible for fluid balance, immune response, and transporting lymph.
Short-term Regulatory Mechanism for MAP
- Autonomic nervous system adjustments serve as short-term regulatory mechanisms for MAP.
Heart Rate and Blood Pressure Response
- During attempts to stand, heart rate increases while blood pressure decreases due to gravity-induced blood pooling.
Main Influence on Vascular Resistance
- Vascular resistance in the systemic circuit is primarily influenced by vessel diameter.
Blood Vessels as Pressure Reservoirs
- Arteries, particularly the elastic arteries, function as pressure reservoirs, allowing continuous blood flow throughout the cardiac cycle.
Average Arterial Pressure during Cardiac Cycle
- The average arterial pressure during the cardiac cycle is referred to as the mean arterial pressure (MAP).
