Question

1)    What is the correct sequence of structures that the blood passes through after it leaves the left ventricle from the choices listed?  
    Choices: arteries, capillaries, pulmonary artery, right atrium, veins, left atrium, right ventricle, pulmonary vein, lungs.

2)    Which of the choices (more than one) control the expansion and recoil of the lungs to create air exchange during heavy breathing?
    Choices: abdominal muscle activity, ribcage movement, diaphragm movement, pectoral muscle activity

3)    Which of the choices is an early adaptation to acclimatizing to high altitude?
    Choices: decreased tidal volume, decreased respiration rate, increased resting cardiac output, increased stroke volume

4)    The amount of blood ejected from the left ventricle during each beat is the ?  
    Choices: cardiac output, a-VO2 difference, heart rate, stroke volume

5)    All of the choices normally increase during an aerobic exercise session EXCEPT:
    Choices: end-diastolic volume, cardiac contractability, cardiac output, diastolic blood pressure

6)    List two structural differences between the heart of a healthy untrained person and the heart of an endurance athlete.

7) Describe the Bohr Effect and its importance during exercise.

Explanation / Answer

1) Arteries capillaries veinright atrium right ventricalpulmonary artery lungs pulmonary vein left atrium

2) abdominal muscle activity, ribcage movement, diaphragm movement.

3) there is an increase in cardiac output with tachycardia, no change in stroke volume. Tidal volume increases as more oxygen is needed to be inhaled. Same goes for respiration rate.

4) stroke volume.

Cardiac output account for one minute the heart pumps blood.

Heart rate is the number if beatd per minute

A-vO2 difference is the arteriovenous oxygen system. It is the difference between oxygen content between the arterial blood and venous blood.

5) diastolic blood pressure

6) Increased mass, thickness and volume.there is change in elasticity. There is increased blood vessel width.these occur in heart of an athlete.

7) bohr effect states that hemoglobin's oxygen binding is inversely related both to acidity and to the concentration of carbon dioxide.
