The respiratory system provides __________ to body tissues and removes waste products.
Carbon dioxide
Lactic-acid
Oxygen
Water
Main function of the respiratory system are...
Pulmonary circulation & gas exchange
Pulmonary ventilation & gas exchange
Thermoregulation & gas exchange
The chamber of the chest is known as the...
Lungs
Thoracic cavity
Diaphragm
Pharynx
Select the correct answer which best describes the breathing mechanics during INSPIRATION.
Ribs move down and in, diaphragm relaxes and moves upwards, chest decreases, external intercostal muscles relax.
Ribs move down and in, diaphragm contracts and moves downwards, chest decreases, external intercostal muscles relax.
Ribs move up and out, diaphragm relaxes and moves upwards, chest increases, external intercostal muscles relax.
Ribs move up and out, diaphragm contracts and moves down/flattens, chest expands, external intercostal muscles contract.
Explain the process of gas exchange at the alveoli.
Concentration of oxygen in the alveoli is high. Concentration of oxygen in the blood is low. This creates a steeper diffusion gradient/ oxygen diffuses quicker. Oxygen moves from the alveoli into the blood.
Concentration of oxygen in the alveoli is low. Concentration of oxygen in the blood is high. This creates a steeper diffusion gradient/ oxygen diffuses quicker. Oxygen moves from the blood into the alveoli.
Concentration of oxygen in the alveoli is the same as the concentration of oxygen in the blood. This removes the diffusion gradient. Oxygen does not move anywhere.

Asthma is...
a disorder characterized by low bone mass, leading to bone fragility, and consequent increase in fracture risk.
a medical condition in which a person's spine has a sideways curve. The curve is usually "S"- or "C"-shape.
a common condition where airways can become restricted. The tightening of the muscles surrounding the trachea prevent gases from freely moving in or out.
a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level.
