Question 10

Where does the blood go?

Answer 10

Pulmonary circuit, systemic circuit, coronary arteries

Question 11

What is the pulmonary circuit

Answer 11

leads to the lungs

Question 12

What is the systemic circuit

Answer 12

leads to body cells

Question 13

What are the corinary arteries

Answer 13

leads to the heart

Question 14

What is the job of the sinoatrial node (SA node)

Answer 14

Tell the atrium to constrict (natural pacemaker)

Question 15

The SA node is located

Answer 15

Above the atrium

Question 16

The Atriovanticular node’s function is (AV node)

Answer 16

Gets signal from SA node to tell the ventricles to contract

Question 17

What is systolic pressure

Answer 17

pressure during venticular contraction

Question 18

What is diastolic pressure

Answer 18

pressure when the heart is filling up again

Question 19

What is primary hypertension?

Answer 19

High blood pressure the gradually develops overtime

Question 20

What is secondary hypertension?

Answer 20

Appears suddenly, more common for athletes (high level)

Question 21

What is coranary disease?

Answer 21

Built up plaque in the arteries

Question 22

Why are corinary arteries important

Answer 22

They provide oxygen, nutrients, and blood to the heart

Question 23

What is cardiac output

Answer 23

volume of blood pumped out per min

Question 24

what is cardiovascular drift?

Answer 24

When the SV and HR increase but the Q does not

Question 25

What is the lactate accumulation

Answer 25

The point at which lactic acid begins to increase exponentially with the intensity of exercise

Question 26

What is the lactate threshold?

Answer 26

It is the point where the aerobic metabolism can no longer be efficient on its own, and the anaerobic metabolism kicks in (pyruvate is turned into lactic acid, more than acetol CoA)

Question 27

What is oxygen deficit?

Answer 27

When you begin exercise but body supply has not caught up with new demand and anaerobic pathways become dependant

Question 28

What is EPOC?

Answer 28

After you finish exercising and your body is still trying to recover from the intensity, more oxygen than needed and the breakdown of lactic acid begins

Question 29

cellular respiration is also called

Answer 29

oxidative phosphorylation

Cellular respiration takes place in the

Answer 30

mitocondrea

Question 31

Glycolosis takes place in the

Answer 31

cytoplasm

Answer 32

Type IIB

Question 33

Glycolysis uses which muscle fiber?

Answer 33

Type IIA and IIB (Fast twitch)

Question 34

Cellular respiration uses which muscle fiber?

Answer 34

Type I (Slow twitch)

Question 35

How long does it take to relpenish from cellular respiration?

Answer 35

24hrs

Question 36

Why do we get tired after a run (cellular respiration)

Answer 36

Because our body is running out of glycogen

Question 37

How long does glycolysis last?

Answer 37

10 seconds-2 minuites

Question 38

How long does ATP-PC system last?

Answer 38

0-10 seconds
