The amount of blood being pumped through your body changes constantly due to the demands of daily life. In this lesson, you will learn how your body adjusts the heart rate and stroke volume to increase or decrease blood flow.
Cardiac Output
The volume of blood your heart pumps per minute, known as your cardiac output, varies with the demands you put on your body. We previously learned that the cardiac output (CO) is calculated by multiplying the number of heartbeats per minute (which is your heart rate, or HR) times the volume of blood pumped out of the heart with each heartbeat (which is your stroke volume, or SV). So:
cardiac output (CO) = heart rate (HR) x stroke volume (SV)
The cardiac output of your heart is a constantly changing amount that adjusts to any physical or emotional demands you put on your body. In this lesson, we will look at some of the factors that influence your heart rate and stroke volume.
Plants need energy from the sun, water from the soil, and carbon from the air. The plant uses the carbon to form the leaves and stem and roots. I can go more into detail in the comments if you need.
Answer:
Approximately 100 to 150 mol/L of ATP are required daily
Explanation:
Basically, the human body turns over its weight in ATP daily.
C) Lactic acid and energy
This is the reason we feel a burning sensation during strenuous exercise.
