Question 5

1. Alveolar Ducts
2. _________
   3.__________
3. Tissues

Answer 5

2. Alveoli
3. Blood

Question 6

Arteries and Veins

Answer 6

Arteries- thick walled, carries oxygenated blood away from heart
Veins- thin walled, carries deoxygenated blood towards the heart, uses valves to keep blood flowing

Question 7

Bradycardia vs tachycardia

Answer 7

Bradycardia - when heart rate is at rest/during sub-maximal exercise (decreased)
Tachycardia - heart rate over 100 beats per min while at rest

Question 8

External vs internal respiration

Answer 8

External- exchange of gases(external environment) occurs in lungs/alveoli
Internal- exchange of gases (internal environment)
occurs in tissues

Question 9

Systolic vs Diastolic pressure

Answer 9

Systolic- the pressure in the arteries when the heart beats (maximum)
Diastolic- the pressure in the arteries between heart beats (minimum)

Question 10

Explain the pathway of electrical conduction system of the heart

Answer 10

Begins with SA node atrial muscles contract goes to AV node then to bundle of HIS then bundle branches then purkinje fibers then ventricles contract
