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.
1. 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.

Diaphragm and rib muscle

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 cells from the heart going to the lungs to receive proper amount of oxygen?
Open circulation
Coronary circulation
Systemic circulation
Pulmonary circulation
In which organ do gas exchange and gas transport occur?
Lungs and blood vessels
Blood vessels
Lungs and tubes
Tubes
