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

what is the cartilaginous structure that stops food entering the trachea
(a)
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
What is the role of hemoglobin in erythrocytes?
Carrying carbon dioxide
Fighting infections
Transporting oxygen
Clotting blood
What is the primary function of the trachea?
To produce sound
To exchange gases
To conduct air to the lungs
To filter blood
What is the role of the larynx in the respiratory system?
To filter air
To produce sound
To exchange gases
To transport oxygen
What is the primary function of the pulmonary veins?
To carry deoxygenated blood from the heart to the lungs
To regulate blood pressure in the lungs
To carry oxygenated blood from the lungs to the heart
To transport nutrients to the lungs
What is the role of the sinoatrial node in the heart?
To regulate blood pressure
To filter blood
To initiate the heartbeat
To pump blood to the lungs
What is the primary function of the bronchioles in the respiratory system?
To filter air
To exchange gases
To conduct air to the alveoli
To produce mucus
which of the following is the smallest in diameter
primary bronchi
secondary bronchi
tertiary bronchi
bronchioles
What is the primary function of the pleura in the respiratory system?
To produce mucus
To protect the lungs
To conduct air to the alveoli
To exchange gases
which is correct (multiple answers)
parietal pleura is attached to the thorax and the visceral pleura surrounds the lungs themselves. The cavity between the two contains fluid
The serous fluid continuously lubricates the pleural surface and makes it easy for them to slide over each other during lung inflation and deflation.
visceral pleura is attached to the thorax and the parietal pleura surrounds the lungs themselves
The serous fluid allows diffusion across the membrane of the alveoli
What is the role of the aorta in the circulatory system?
To regulate blood pressure
To filter blood
To carry deoxygenated blood to the lungs
To carry oxygenated blood from the heart to the body
What is the primary function of the capillaries in the circulatory system?
To produce blood cells
To pump blood
To exchange nutrients and waste between blood and tissues
To transport oxygen
