At very high altitude, the Red Blood Corpuscles in the human body will : (1) increase in size (2) decrease in size (3) increase in number (4) decrease in number

Description : At very high altitude, the Red Blood Corpuscles in the human body will : (1) increase in size (2) decrease in size (3) increase in number (4) decrease in number

Last Answer : (1) increase in size Explanation: Red Blood cells contain haemoglobin which is what the oxygen binds with to form oxyhaemoglobin which is then transported to the different cells around the body. Oxygen ... the current number of red blood cells in the body cannot meet the cells demands for oxygen.
