Name four gases that make up the air you breath in. What is the difference between inspired air and alveolar air? When oxygen is dissolved in the blood, how is it carried to the rest of the body? Name three ways or forms in which carbon dioxide is carried in the blood. Explain the causes of the following respiratory disorders: a. Hypoxia b. Ischemic hypoxia c. Anemic hypoxia d. Histotoxic hypoxia e. Asthma f Chronic bronchitis g. Emphysema h. Lung cancer What is the function of the enzyme carbonic anhydrase in the respiratory system? What are the functions of (a) the nose and (b) the epiglottis in the respiratory system? Name the three parts of the bronchial tree. Hemoglobin transports both oxygen and carbon dioxide. True or false? When do the following actions take place? a Quiet respiration b Forced respiration List six factors that can affect gas exchange in the lungs. We need oxygen; however, excess oxygen can have adverse side effects. Name four adverse side effects of excessive oxygen.

Solution

10- The difference between inspired air and alvelor air is

The amount of air inspired (taken in) during the time of inspiration is called inspired air.

The amount of air present in the alvela after inspiration is called alvelor air.

11- oxygen gets dissolved in blood, This process takes place in lungs and this oxygenated blood is carried to heart by pulmonary veins . Heart pumps blood to all parts of the body through arteries.

17- True , Haemoglobin carries both oxygen and carbon dioxide.

19 - Factors affecting gas exchange in lungs are

a - surface area of the membrane.

b - pressure gradient of gases in and out of lungs.

c - thickness of the membrane.

d - Distance of diffusion of air in to blood.

e - voluntary activities over respiration.

f - Health conditions of lungs.
