Cardiorespiratory Part 1

identify the function of the alveoli

• Gas Exchange

• Conduction

• Exhalation

• Pressure Changes

What causes Inhalation?

• Cognition

• Pressure Increase in the lungs, decrease in the external Environment

• Pressure Decrease in the Lungs, higher pressure in the external environment

• Concentration of Ca+ inside the intercostal muscles

The valve on the right side of the heart

What causes the 'lub, dub' (heart sounds)

• Blood against Cardiac Walls

• Contraction of the Artium

• Contraction of the Ventricles

• Opening and closing of heart valves

What is the role of thrombocytes

• clotting broken blood vessels

• fighting infection

• carries oxygen

• determines blood type

select the correct order

• trachea, nasal cavity, larynx, pharynx

• nasal cavity, larynx, pharynx, trachea

• nasal cavity, pharynx, larynx, trachea

• nasal cavity, pharynx, larynx, oesophagus

what is the cartilaginous structure that stops food entering the trachea

What is the primary function of erythrocytes?

• Fighting infections

• Regulating blood pressure

• Transporting oxygen

• Clotting blood

What is the main function of the diaphragm in respiration?

• To humidify the air

• To filter air entering the lungs

• To decrease lung volume during exhalation

• To increase lung volume during inhalation

What is the primary function of leukocytes?

• Clotting blood

• Transporting oxygen

• Fighting infections

• Regulating blood pressure
