Document Summary

Functions of the respiratory system include: transport of oxygen from air to blood, removal of carbon dioxide from blood to air, control of blood acidity (ph, temperature regulation, forming a line of defense to airborne particles. Located in the thoracic cavity, surrounded by the rib of cage and diaphragm. Airways consist of the nasal cavity and the mouth, which join at the pharynx, pharynx leads into the voice box/larynx then trachea then two bronchi then smaller bronchioles then alveoli. Alveoli: site of gas exchange in the lung. Pulmonary artery delivers deoxygenated blood to the lungs. Pulmonary artery branches extensively to form a dense network of capillaries around each alveolus. Capillaries have a thin endothelial walls and large total cross-sectional area. Form the capillaries, the oxygen-rich blood flows back to the left side of the heart through the pulmonary vein. Roughly 300 million alveoli in a healthy human lung, with a diameter 0. 3 mm.

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

Mouth pharynx, trachea, bronchi, alveoli

Larynx, esophagus, trachea, bronchi, alveoli

Nose, bronchi, larynx, trachea, lung

Epiglottis, trachea, cricoid, bronchi, alveoli
