Study Notes
Hemorrhage Effects
- A significant loss of blood leads to a lowering of blood pressure due to changes in cardiac output.
Stroke Volume Calculation
- With an End-Diastolic Volume (EDV) of 120 ml/beat and an End-Systolic Volume (ESV) of 50 ml/beat, the Stroke Volume (SV) is calculated to be 70 ml/beat.
Cardiac Output Insights
- A slow heart rate contributes to an increase in End-Diastolic Volume (EDV), Stroke Volume (SV), and the force of contraction in the heart.
Norepinephrine Function
- Norepinephrine accelerates heart function by facilitating quicker attainment of the threshold needed for action potentials.
Blood Vessel Structure
- The Tunica Media layer of blood vessels plays a crucial role in maintaining blood pressure.
Absence of Elastic Tissue
- Capillaries and venules are the types of blood vessels that do not contain elastic tissue.
Capillary Types in Red Bone Marrow
- Sinusoid capillaries are predominantly found in red bone marrow, where newly formed blood cells enter circulation.
Blood Flow Relationships
- Blood flow is directly proportional to blood pressure and inversely proportional to total peripheral resistance.
Pulse Pressure Definition
- Pulse pressure is defined as the difference between systolic pressure and diastolic pressure.
