1. Stroke volume is the amount of blood pumped out of the heart with each contraction. It is typically measured in milliliters per beat.
2. Cardiac output is the total amount of blood pumped by the heart in one minute. It is calculated by multiplying the stroke volume by the heart rate.
3. "Lup" refers to the first heart sound, also known as S1, which is produced by the closure of the mitral and tricuspid valves during ventricular contraction.
4. "Dup" refers to the second heart sound, also known as S2, which is produced by the closure of the aortic and pulmonic valves during ventricular relaxation.
2. Cardiac output is the total amount of blood pumped by the heart in one minute. It is calculated by multiplying the stroke volume by the heart rate.

1. Stroke Volume:
Stroke volume is the amount of blood ejected from the left ventricle during a single heartbeat. It is measured in milliliters (mL). Stroke volume is determined by several factors, including:
- Ventricular filling: How much blood enters the ventricle before contraction.
- Force of ventricular contraction: How strongly the ventricle contracts.
- Afterload: The pressure against which the ventricle must contract to eject blood.
2. Cardiac Output:
Cardiac output is the total volume of blood pumped by the heart per minute. It is calculated as the product of stroke volume and heart rate:
Cardiac Output = Stroke Volume x Heart Rate
Cardiac output represents the blood flow to the body and is essential for oxygen and nutrient delivery to tissues.
3. "Lub"
"Lub" is the first sound of the heart cycle, which occurs when the mitral and tricuspid valves close at the beginning of ventricular systole (contraction). It is a low-pitched sound, caused by the vibration of the valves and the atrial wall.
4. "Dup"
"Dup" is the second sound of the heart cycle, which occurs when the aortic and pulmonic valves close at the end of ventricular systole. It is a higher-pitched sound than "lub" and is caused by the recoil of the ventricular walls and the closure of the valves.
