Acid-Base Balance in Physiology

The video tutorial explains the concepts of acidosis and alkalosis, focusing on the blood's pH balance. It distinguishes between respiratory and metabolic types, detailing how carbon dioxide and bicarbonate levels affect acidity. The tutorial covers the chemical reactions involved and how medical professionals assess these conditions through blood tests.

What is the normal pH range for blood?

• 6.35 to 6.45

• 7.35 to 7.45

• 8.35 to 8.45

• 9.35 to 9.45

What does the 'H' in pH stand for?

• Hydrogen

• Helium

• Hydroxide

• Helix

Which ion is primarily responsible for changes in blood pH?

• Potassium

• Calcium

• Hydrogen

• Sodium

Which compound is formed when carbon dioxide mixes with water in the blood?

• Carbonic acid

• Hydrochloric acid

• Nitric acid
