Document Summary
Internal defenses: antimicrobial proteins: these proteins function by attacking microbes directly or by impeding reproduction, complement system: causes lysis of invading cells and helps trigger inflammation. Interferons: released by virally-infected cells: helps healthy cells resist infection. Internal defenses: natural killer cells: nk cells, attacks body cells that are virally infected or cancerous, releases chemicals that initiates apoptosis (i. e. , cell death) Insulin-dependent diabetes mellitus type i diabetes: multiple sclerosis, rheumatoid arthritis, a cancerous body cell will be bound and attacked by _____, cytotoxic t cells, helper t cells, b cells, plasma cells. Chapter 44: osmoregulation and excretion: concept 44. 1: osmoregulation balances the uptake and loss of water and solutes. Inside a cell you construct, you place a 1m sugar solution. You place the cell in a 2m sugar solution. Isotonic to their surroundings, do not regulate the osmolarity: osmoregulators, use energy to control uptake and loss of water, meeting osmotic challenges, marine bony fishes, hypoosmotic to sea water.
