Textbook Question
Chapter 42, Problem 8TYU
DRAW IT Plot blood pressure against time for one cardiac cycle in humans, drawing separate lines for the pressure in the aorta, the left ventricle, and the right ventricle. Below the time axis, add a vertical arrow pointing to the time when you expect a peak in atrial blood pressure.

MATCH the NUMBERS from m the heart diagram with the description: some numbers can be used more than once.
The Part II: Cellular senescence is observed when there is obstruction of the coronary circulation to the muscle tissue of the heart. If the left anterior descending artery (a.k.a. “Widow maker”) is occluded, predict an alternative route of blood flow to the myocardium. Start from the left coronary artery.
Question
Estimate the volume of a human heart (in mL) using the following measurements/assumptions:
Blood flow through the aorta is approximately 16.8 cm/s.
The diameter of the aorta is approximately 3.0 cm.
Assume the heart pumps its own volume with each beat.
Assume a pulse rate of 90 beats per minute.

Heart rate and blood pressure work together to ensure that blood reaches cells at a rate that is sufficient to supply nutrients and remove waste products. If one variable decreases the other will increase to maintain this balance. For example, if the body detects a drop in blood pressure, it will help to correct this imbalance by increasing heart rate until the body can adjust blood pressure by other methods. Watch these videos to learn the terminology and science of blood pressure along with how to take a proper blood pressure reading. https://www.ausmed.com/cpd/articles/how-to-take-blood-pressure When a person is well hydrated and healthy the body can make these adjustments without you ever being aware.
