Answer 1

1. Hyperventilation is a rapid and speed breathing. It causes loss of CO2 from the body which leads to increase in blood pH. Hyperventilation removes more carbon dioxide from the blood and thus reducing hydrogen ions in the blood which results in increase pH of the blood. Hyperventilation will increase blood pH. True

2. The pressure exerted by air with in the alveoli is called intra alveolar or intrapulmonary pressure. Intrapulmonary pressure during inspiration is 760 mmHg.

3.In response to contraction of the diaphragm the thoracic volume increases and inspiration occurs.

4.The major way carbon dioxide is transported in the body as bicarbonate ions in the blood.

5. The enzyme carbonic anhydrase catalyzes the reaction: carbonic acid --> hydrogen ions + bicarbonate. -- True

6. Surfactant main function is to lower the surface tension. Surfactant will increase the alveolar surface tension.-- False

7. The major type of connective tissue found in lymphatic tissue is reticular connective tissue.

8. Functions of the lymphatic system include Regulation of interstitial fluid volume, absorption of dietary fats, immune response. O2 transport is done by blood. Option is Oxygen transport.

9. Organ that protects the body from blood pathogens is lymph nodes.

10. Characteristic of lymphatic vessels include endothelial cells, they have valves, and they have flaps that open and close. Option is Lymph fluid moves towards the tissues.
