WorksheetsPRE - TEST: RESPIRATORY AND CIRCULATORY SYSTEM
Total questions: 15
Worksheet time: 4mins
What important process happens in the netlike structure labeled A?
Nitrogen and oxygen are exchanged.
Carbon dioxide and oxygen are exchanged.
Nitrogen and carbon dioxide remain constant.
Carbon dioxide and oxygen diffuse into the blood.
What structure of the Respiratory System is labeled B in the diagram?
Alveolus
Bronchi
Bronchiole
Pharynx
Why is the lung considered as the primary organ of the respiratory system?
Because it is the largest organ of the system.
Because it has two parts: the right and left lungs.
Because it is located near the middle of the chest cavity.
Because it contains the alveoli that is responsible for gas exchange.
Which of the following statements about the human respiratory system is false?
The bronchioles branch into bronchi.
Alveolar ducts connect to alveolar sacs.
When we breathe in, air travels from the pharynx to the trachea.
Gas exchange between the lungs and blood takes place in the alveolus.
Which structure is responsible for the movement of the chest cavity during the breathing process?
Bronchi and trachea
Larynx and pharynx
Nasal cavity and pharynx
Diaphragm and rib muscle
Which is the order of airflow during inhalation?
Nasal cavity, trachea, larynx, bronchi, bronchioles, alveoli.
Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.
Nasal cavity, larynx, trachea, bronchioles, bronchi, alveoli.
Nasal cavity, trachea, larynx, bronchi, bronchioles, alveoli.
Which of the following statements about the circulatory system is false?
Blood in the aorta is oxygenated.
Blood in the pulmonary vein is oxygenated.
Blood in the pulmonary artery is oxygenated.
Blood in the inferior vena cava is deoxygenated.
Which is the main organ of circulation?
Blood
Heart
Capillary
Blood vessels
How do arteries differ from veins?
Arteries carry blood.
Arteries are thin-walled and are used for gas exchange.
Arteries have thicker wall layers to accommodate the changes in pressure from the heart.
Arteries have thinner wall layers and valves and move blood by the action of skeletal muscle.
Which blood vessel carries blood from all parts of the body to the heart?
Aorta
Vena cava
Pulmonary vein
Pulmonary artery
What type of circulation is responsible for removing oxygen-depleted blood?
A. Open circulation
Coronary circulation
Systemic circulation
Pulmonary circulation
What is the correct order of blood circulation starting from the different parts of the body, lungs and, back to the body?
Superior and inferior vena cava, right atrium, right ventricle, lungs, left atrium, left ventricle, aorta, body
Superior and inferior vena cava, left atrium, left ventricle, lungs, right atrium, right ventricle, aorta, body
Superior and inferior vena cava, left ventricle, right ventricle, lungs, left atrium, right atrium, aorta, body
Superior and inferior vena cava, right atrium, left ventricle, lungs, left atrium, right ventricle, aorta, body
In which organ do gas exchange and gas transport occur?
Tubes
Blood vessels
Lungs and tubes
Lungs and blood vessels
Which best defines this pair of words: Respiratory system: Circulatory system?
Gets the oxygen needed by the cells: Delivers the oxygen to the cells
Ingests food and breaks it down into usable nutrients: Excretes solid waste products
Cleans dissolved waste products from the blood and excretes them: Excretes solid waste products.
Moves materials between body systems, including oxygen, nutrients, hormones, and waste products: Allows gas exchange between cells and environment
How does the respiratory system work with circulatory system?
Always work independently from one another.
Work together to keep blood pumping to all parts of the body.
Work together only when we are active, and never when we are resting or sleeping.
Work together to deliver oxygen to cells and remove carbon dioxide from the body.
