Heart
How many chambers are there in the heart?
4
What is the number of breaths per minute called?
Respiratory rate
What is the role of red blood cells?
Transport O2
O2 consumption = need
What are 2 acute cardiovascular response?
Increase HR, SV, Q
Blood flow redistribution
A-VO2 Diff
Blood pressure
What are the top 2 chambers called
Atrium
How many trachea do you have?
one
What are the types of blood vessels?
Veins, arteries, capillaries
Is it preferable to breathe in through the nose or mouth and why?
Nose
- filters air
-humidifies and warms air
What are 2 acute respiratory response?
Increase RR, TV, V
What are the bottom 2 chambers called?
Ventricles
What is the calculation for ventilation?
V=TV x RR
What is the role of platelets?
Blood clotting
What is the main muscle involved in breathing?
Diaphragm
What is vasodilation and vasoconstriction?
and during exercise where would these occur
Vasoconstriction
- narrowing of blood vessels
- at non-vital organs
vasodilation
- widening of blood vessels
- at working muscles
What are the roles of the cardiovascular system?
Transport O2 and CO2
Immunity
Thermoregulation
Transport nutrients and waste
Bring in O2
Breathe out CO2
Speech
Filter dust
What direction do the blood vessels carry blood?
Veins - to heart
Arteries - away from heart
What is A-VO2 Difference?
What is a prohibited substance that improves the cardiorespiratory system?
Beta blockers
EPO
Blood doping
What is the pathway of blood through the heart?
RA, RV, Pulmonary artery, lungs, pulmonary vein, LA, LV, Aorta
What is the pathway of air through the respiratory system?
Mouth, pharynx, larynx, trachea, brochus, bronchioles, alveoli
List all the components in blood?

Plasma
Platelets
What does EPOC stand for and happens to HR during EPOC?
Excess Post-exercise O2 consumption
Decreases
What is a risk of blood doping?
