Is Valentina's blood pH more acidic or more basic than normal? Has the number of hydrogen ions in her blood increased or decreased? Explain. Her blood is not acidic c While Valentina is recovering, a friend on social media tells her to eat only "alkaline foods," claiming eating alkaline foods will correct her pH disturbance. But Valentina is taking an A&P course, and she knows the foods we eat don't affect our blood pH due to our buffer systems. How are the buffer systems in Valentina's blood

1 Valentina Blackhorse presents to the emergency department with respiratory distress due a diagnosis of
COVID-19. The respiratory therapist measures the pH of her blood and determines that it is 7.05.
Neutral
a Is the pH of her blood acidic, basic, or neutral?
b The normal pH of human blood is 7.35-7.45. Is Valentina's blood pH more acidic or more basic than normal?
Has the number of hydrogen ions in her blood increased or decreased? Explain.
Her blood is not acidic
c While Valentina is recovering, a friend on social media tells her to eat only "alkaline foods," claiming eating
alkaline foods will correct her pH disturbance. But Valentina is taking an A&P course, and she knows the foods
we eat don't affect our blood pH due to our buffer systems. How are the buffer systems in Valentina's blood
responding to her pH disturbance?
2 Let's suppose that the foods we eat really could affect the pH of our blood, and you chose to eat an "alkaline
diet" with only foods that are highly basic in pH.
a What would happen to the number of hydrogen ions in your blood if this were possible?
