| Questão | Responda |
| Water accounts for what percentage of total body weight? | 60% |
| Body water has two components? | Water inside cells (intracellular fluid) Water outside cells (extracellular fluid) |
| Intracellular fluid makes up ... of total body water. Extracellular fluid makes up...of total body water. | 2/3 1/3 |
| ECF is subdivided into which two compartments and what percentages make up these compartments? | Interstitial fluid (80%) Plasma (20%) |
| If too much fluid moves out of the plasma and into the interstitial spaces, this results in? | Tissue swelling (Oedema) |
| The protein content of the plasma is much higher than in the interstitial fluid? | Yes |
| Plasma proteins contribute towards the osmotic pressure of the plasma. This is called the | Colloid Osmotic Pressure |
| Plasma proteins help to ? | retain water in the plasma. |
| What can result if plasma protein levels fall? | Severe starvation. |
| What type of fluid is found in the spaces within the brain, and also surrounding the outer portions of the brain and spinal cord ? | Cerebrospinal fluid |
| Is cerebrospinal fluid part of the ICF or ECF? | ECF |
| CSF volume is around? | 150ml |
| Does CSF have cells present? | No |
| Is CSF composed differently to plasma fluid? | Yes |
| What function does CSF have? | Supports and protects the brain and spinal cord and helps supply nutrients. |
| Are the walls of brain capilliaries more or less permeable than capilliaries elsewhere in the body? | Less |
| This is known as the... | Blood brain barrier. |
| Intracellular fluid. How many litres? | 27 |
| Interstitial fluid | 11 |
| Plasma | 3-3.5 litres |
| How much water do the kidneys lose each day? | 0.5-1.5 litres |
| How much water do the lungs lose each day? | 0.3-0.4 litres |
| How much water do we lose through skin and sweat each day? | 0.2-1litre |
| How much water do we lose through faeces each day? | 0.1-0.2litres |
| What is the barrier between the intracellular fluid and the interstitial fluid? | Cell membrane |
| What is the barrier between the interstitial fluid and the plasma fluid? | Capillary walls |
