Which chamber of the heart receives oxygen poor blood from the body?
RA (Right Atrium) then the blood moves to the RV (Right Ventricle) ; The right side of the heart receives oxygen poor blood from the superior & inferior veins, which is blood from the body. Oxygen poor blood goes right into the heart.
Which Chamber pumps oxygen rich blood to the body?
LV (Left Ventricle); The left side of the heart receives oxygenated blood, but it pushes that blood into the body from the LV. The blood LeaVes the heart, and goes into the body.
What do the valves in your heart do?
It ensures blood moves in one direction properly.
How does an increase in blood CO2 levels affect respiratory rate? and why?
CO2 levels forces the body to hyperventilate. When the body is lacking oxygen, it finds ways to push out the carbon and pull in more oxygen.
Which ventricle is thicker and why?
The left ventricle. It needs the power to pump out all the oxygenated blood into the body. It is the power house of the heart.
Why is the systolic number larger than the Diastolic when measuring your blood pressure?
Systolic is the contraction of the heart, it puts a lot more effort into pumping blood into the body. Diastolic is the resting rate and in-between beats. It will always read systolic / diastolic
Systolic
Contraction of the heart
Diastolic
The in between resting beats.
how would you know your hematocrit be affected if you spent 2 weeks at high elevation?
You could suffer from hypoxia, the hematocrit would increase with the high altitude for long periods of time.
