c) A patient has a CT scan of their abdomen with an absorbed dose of 25.0 mGy. The scan ends near the top of their pelvis. Assume that 15% of their bone is scanned, 20% of their skin, 90% of their colon, 25% of their bladder and 10% of their lungs but none of their liver, stomach and gonads. A further 20% of tissue characterised as 'remainder of the body' is also exposed during the scan. The tissue weighting factors for various organs is listed in the table below: Tissue Tissue weighting Tissue Tissue weighting factor factor skin 0.01 oesophagus 0.04 bone marrow 0.12 bladder 0.04 bone surface 0.01 breast 0.12 brain 0.01 gonads 0.08 lung 0.12 thyroid 0.04 liver 0.04 salivary glands 0.01 stomach 0.12 remainder of body 0.12 colon 0.12 What is the overall effective dose received by the patient from the CT scan?

Match the tissue shown with its function. option:  1. Present in bone marrow, spleen, and lymph nodes.2. Allows us to think.3. Triceps brachii are needed for arm extension.4. Provides a smooth surface.5. Support and binding of other tissues.6. Stores energy in the form of fat.7. Propulsion of food and liquid through gastrointestinal tract.8. Allows the ribcage to be flexible;necessary for breathing to occur.9. Protective,withstands abrasion.10. Secretion (mucus, HCI, etc.), protection, absorption.11. Propels blood through the heart12. Part of skeletal system: support, movement, production of blood cells.13. The only liquid connective tissue. It transports substances and cells.14. Lines tubules in kidneys.15. Allows for elastic recoil of large arteries like the aorta and of alveoli during exhalation.16. Thin for rapid diffusion of gases17. Creates the mucociliary escalator that protects the respiratory system from microbes and debris.

Susie participates in BPCC's blood drive. Afterward, her red blood cell count is low and her she is slightly dehydrated. Her brain tells her bone marrow to produce more red blood cells and her kidneys to conserve water.  Susie’s bone marrow and kidneys are acting as what part of the homeostatic system?
