| Question | Answer |
|---|---|
| What is the normal pH range of blood? | This is the range the body must maintain for cells to function normally. |
| What happens in respiratory acidosis? | CO₂ builds up because breathing is slowed or impaired, causing the blood to become too acidic. |
| What causes metabolic alkalosis? | Loss of acids (vomiting), too many antacids, or excess bicarbonate can make the blood too alkaline. |
| How do the kidneys help correct acidosis? | They secrete hydrogen ions and reabsorb bicarbonate to raise the pH back to normal. |
| What is the main chemical buffer system in the body? | The bicarbonate buffer system, which helps resist sudden pH changes. |
| What is the main function of the lymphatic system? | To return excess fluid to the bloodstream, filter out pathogens, and support immune responses. |
| What is lymph made of? | Clear fluid containing water, proteins, lymphocytes, and waste products from tissues. |
| What do lymph nodes do? | They filter lymph, trap pathogens, and activate immune cells (B and T cells). |
| What are natural killer (NK) cells? | Specialized lymphocytes that destroy virus-infected cells and tumor cells without needing prior exposure. |
