Document Summary
Autoimmune diseases: white blood cells gone wrong , attack own cells, utilize a bone marrow transplant: helps regulate body temperature. Takes a lot of energy to change the temperature of water, helps to maintain homeostasis more easily. Other protections: blood plays a role in inflammation, which limited spread of infections, leukocytes- white blood cells that destroy foreign things - pathogens (bacteria, viruses, even dust, antibodies float and bind to foreign pathogens to neutralize and destroy them. Antigen: surface cellular marker, friends to leukocytes : platelets: initiate blood clotting to limit blood loss. Helps to regulate the internal environment: stabilize fluid distribution by absorbing or giving off fluid (mainly kidneys) Adh kidney- now water from blood leaves and is retained. Blood serum: identical to plasma, but no fibrinogen (clotting protein), used when seeking to prevent clotting. Plasma: comprises 55% percent of blood, 92% of plasma is just water, mixture of water, proteins, nutrients, electrolytes, nitrogenous waste, hormones, and gases (co_2)
