Term
What is the definition of Heart Rate (HR)
|
|
Definition
| Measure of the number of times, per minute that the heart beats. |
|
|
Term
What is the definition of Stroke Volume (SV)
What happens to the SV while the heart is asapting to CRE conditioning? |
|
Definition
the volume of blood that is pumped with each heartbeat
The SV increases; results in a lower resting HR
|
|
|
Term
| What does it mean if more blood is pumped with each beat of the heart |
|
Definition
|
|
Term
What is the definition of Cardiac Output (Q)?
What is the formula for Cardiac Output? |
|
Definition
the measure of the amount of blood being pumped through the cardiovascular system in liters per minute
(Q) = (SV) x (HR)
|
|
|
Term
What is the definition of Blood Pressure (BP)?
What happens when (Q) increases due to exercise? |
|
Definition
The measure of pressure within the vascular system
The Systolic (BP) rises linearly with (Q) but the Diastolic (BP) remains constant or slightly decreases |
|
|
Term
What is systolic (BP)?
What is diastolic (BP)? |
|
Definition
the measure of vascular pressure during the contraction phase of the heart
The measure of vascular pressure during the relaxation phase |
|
|
Term
What is the definition of Oxygen Extraction?
What else is it refered to as? |
|
Definition
the amount of oxygen that is removed from the arterial blood that is circulate through the skeletal muscles
Arterial Venous Oxygen Differences
or
(a-v)O2 Differences |
|
|
Term
Which Atria collects blood from the body?
Which Atria collects blood from the lungs?
Which Ventricle pumps deoxygenated blood to the lungs?
Which Ventricle pumps oxygnated blood out through the aorta to the body |
|
Definition
Right Atrium
Left Atrium
Right Ventricle
Left Ventricle |
|
|
Term
| Out of the four divisions of the heart, which one has the thickest walls and strongest of the chamber? |
|
Definition
|
|
Term
| What are the four conditioned heart adaptations? |
|
Definition
- (SV) increases - amount of blood pumped with each beat increases
- The strength and tone of the heart muscle improves - left ventricle contractions are stronger
- each heartbeat is able to supply more oxygen to working muscles - eliminates need for increase number of beats per minute during exercise
- lowered resting heart rate
|
|
|
Term
| where does deoxygenated blood travel? |
|
Definition
1. Through the inferior/superior vena cava (IVC) (SVC)
2. Right Atrium
3. Right Ventricle
4. Pulmonary Arteries
5. Lungs (gas exchange occurs here) |
|
|
Term
| Where does oxygenated blood travel from? |
|
Definition
1. lungs
2. pulmonary veins
3. left atrium
4. left ventricle
5. aorta
6. distributed throughout body
7. returns to (SVC)/(IVA) as deoxygenated blood
|
|
|
Term
Oxygenated blood travels through _______, which carries blood away from the heart.
It then travels through _________ which are more elastic and smaller.
From there it travels into microscopic networks of smaller vessels called ___________. |
|
Definition
Arteries
Arterioles
Capillaries |
|
|
Term
| Why are arterioles significant during exercise |
|
Definition
| becuase they irect the blood flow to the working muscles to supple the increase demand for oxygen |
|
|
Term
| After gas exchange occurs in the capillaries deoxygenated blood travels back to the heart through ____________ and then to the larger __________. |
|
Definition
|
|
Term
The respiratory system is composed of ....
(Hint: consist of six parts) |
|
Definition
1. Nose
2. Mouth
3. Trachea
4. Primary and Secondary Bronchi
5. Bronchioles
6. Lungs |
|
|
Term
|
Definition
| the smallest branches in the lungs usually refered to as small air sacs or cavities in the lung that expand its surface area for the exchange of oxygen and carbon dioxide |
|
|
Term
What is Pulmonary Ventilations?
When does pulmonary ventilation take place?
What is the formular for pulmonary ventilation? |
|
Definition
measures in liters per minute of gas exchanged (VE)
When the air is brough into the body and exchanged with air in the lungs
(VE) = (Vt) x (Vf) |
|
|
Term
What is Tidal Volume (Vt)?
What is Respiratory Rate (Vf)? |
|
Definition
Vt is the amount og air in one breath
Vf is the number of breaths per minute |
|
|
Term
when is an added need for oxygen to supply energy to the working muscles necessary?
And how does the respiratory mechanism respond?
Wiith training the body can extract more _______ from the same volume of air ventilated through _________ |
|
Definition
when exercise or physical work begins
it increases respiratory frequency and the depth of the breathing
Oxygen; the lungs |
|
|
Term
What is Maxium Oxygen Consumption (VO2max)
