B3 Thermoregulation/blood sugar/kidneys
| Question | Answer |
|---|---|
| Affected by levels of carbon dioxide and urea | pH |
| Makes up 90% of your blood plasma | Water |
| Removal of toxic substances made in your body. | Exretion |
| Carbon dioxide is a product of this. | Cell respiration |
| Affected by a drop in the tissue fluid and blood pH | Enzymes |
| A change in the shape of an enzyme active site. | Denaturing |
| How carbon dioxide is removed from the body | Breathed out of the lungs |
| The immediate product of protein breakdown | Ammonia |
| The final product of urea breakdown that reaches the kidneys | Urea |
| How waste proteins material leaves the body | Urine |
| Two ways that you take water into your body | Eating and drinking |
| Two things lost from the body in urine | Water and ions |
| We need proteins for.. | Growth and repair |
| General pH of carbon dioxide | Acidic |
| General pH of urea | Alkaline |
| Four things initially filtered out of the blood by the kidneys | Glucose, Water, Ions and Urea |
| Useful substances reabsorbed by the kidneys after filteration | Glucose and some water, some ions (as required) |
| General term for the condition where the kidneys stop working properly | Renal failure |
| Where the kidneys stop working for a short time | Acute renal failure |
| Where the kidneys stop working permanently | Chronic renal failure |
| 2 symptoms of chronic renal failure | feeling sick and losing weight, muscle paralysis, back pain, anaemia, swollen feet, ankles, hands or face |
| Process used to treat patients with kidney failure | Renal dialysis |
| Prevents blood clotting during dialysis treatment | Anticoagulant |
| Type of membrane found in a dialysis machine | Partially permeable membrane |
| How many days a week dialysis needs to be done. | 3-4 times a week on average |
| Substances removed from the blood by dialysis | Urea, excess water and excess salts |
| Substance not removed from the blood by dialysis | Glucose |
| Person who gives a kidney to a patient | Donor |
| Surface proteins that must be matched in kidney transplants | Antigens |
| When a person's immune system attacks a transplanted organ | Rejection |
| Matching an organ characteristics with a patient | Tissue-typing |
| Drugs used to treat transplant patients to prevent organ rejection. | Immunosuppressant |
| Patients who have had transplants are at risk of this for the rest of their lives due to the drugs they take. | Infecttions |
