Document Summary

Intakes o2 and distributes it through circulatory system, exhales. Pulmonary ventilation movement of air in and out of lung. External respiration exchange of gases between blood and air of alveoli. Transport of respiratory gases role of blood in transport of gases between lungs and tissues of the body. Internal respiration gases exchange between blood in systemic capillaries and tissue cells. Raising and lowering of the diaphragm muscle will cause the lungs to act like a pump. Conduction zone (passageways) => nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles. These are non- absorptive structures and pipes that carry the oxygenated air into the lungs. Perform functions that disinfect the air, warm the air, Respiratory zone (site of gas exchange) => composed of respiratory bronchioles, alveolar ducts and alveoli (microscopic). Alveoli are tiny air bags that are microscopic, massive surface area. Terminal bronchioles are the nest set of the conducting system, extremely.

1) At what point is the amount of oxygen at its highest?

		in the capillaries during strenous activity
		in the lungs
		in the capillaries at rest
		in muscle tissue during strenous activity

2) You have diagnosed a patient with an iron deficiency. Themost likely result of this is

		low carbon dioxide content
		very red blood
		low oxygen content
		high oxygen content

3) Why are insects limited to relatively small sizes?

		Their respiratory system relies on diffusion which is slow overlong distances
		Their respiratory muscles are smooth muscle only
		They have a closed circulatory system
		Their exoskeleton cannot support larger-bodied animals

4) Air rushes into the lungs of humans during inhalationbecause

		the volume of the thoracic cavity increases
		pressure in the alveoli increases
		the diaphragm contracts and pushes upward on the chestcavity
		smooth muscle lining the trachea and bronchi contracts andcauses their volume to increase
