Cardiorespiratory System DHS

The blood vessels that carry oxygen-rich blood from the heart to the body are

• Arteries

• Veins

• Capillaries

• Red blood cells

The blood vessels that carry de-oxygenated blood from the body back to the heart and then lungs are

• Arteries

• Arterioles

• Veins

• Aorta

Besides delivering oxygen to your muscles, what is another important function of the cardiorespiratory system?

• Eliminating carbon dioxide from cells

• Eliminating carbon monoxide from cells

• Absorbing vitamins

• Obtaining nutrients from food

Which two gases are exchanged in the lungs?

• Oxygen & helium

• Oxygen & carbon monoxide

• Oxygen & ATP

• Oxygen & carbon dioxide

Which of the following describes how the cardiovascular system works with the respiratory system to provide oxygen to muscles?

• Cardiovascular system: inhalation of oxygen and exhalation of carbon dioxide. Alveoli/capillaries: site of gas exchange. Respiratory system: pumps blood and delivers oxygen to muscle cells.

• Respiratory system: inhalation of oxygen and exhalation of carbon dioxide. Alveoli/capillaries: site of gas exchange. Cardiovascular system: pumps blood and delivers oxygen to muscle cells.

• Respiratory system: inhalation of oxygen and exhalation of carbon dioxide. Trachea/capillaries: site of gas exchange. Cardiovascular system: pumps blood and delivers oxygen to muscle cells.

• Respiratory system: inhalation of oxygen and exhalation of carbon monoxide. Arteries/capillaries: site of gas exchange. Cardiovascular system: pumps blood and delivers oxygen to muscle cells.

The sum of HR X Stroke volume =

• Cardiac Output

• Tidal Volume

• Respiratory rate

• Heart rate

Ventilation is

• The amount of air breathed in each breath

• The amount of air breathed in and out in 1 minute

• Tidal Volume

• The amount of blood pumped in 1 minute

When O² doesn't meet the demands of our muscles when our intensity increases is called?

• O² Deficit

• EPOC

• Steady State

When we have more O² than the demands of our muscles when our intensity decreases this is called?

• O² Deficit

• Steady State

• O² Debt

What is diffusion?

• movement of blood out of the left ventricle

• movement of molecules from high concentration to low concentration 

• movement of molecules from low concentration to high concentration
