Explanation:

• Alveoli is a tiny bag like structure found within lungs which is surrounded by pulmonary capillaries. gaseous exchange takes place between alveolar air and blood within pulmonary capillaries.
• Tuberculosis is a bacterial disease caused by Mycobacterium tuberculosis. This disease is inhibited by using a live attenuated vaccine named BCG vaccine. BCG vaccine is an attenuated live culture of Bacillus of Calmette and Guerin strain of Mycobacterium bovis.
• deoxygenated blood is pumped from right ventricles of heart into pulmonary arteries through pulmonic valve. oxygenated blood is pumped from left ventricle into aorta( a artery) through aortic valve.
• Lymph is a clear - white fluid that carry inactivated leukocytes and bacteria into the lymph node where activation of lymphocytes take place. After that lymph carried this activated lymphocytes to the site of infection.
• when RBC destroyed, hemoglobin is broken down into heme and globin. This heme is converted into biliverdin then into bilirubin in liver.
