PHS 3342 Chapter 2: Blood Part 1
Document Summary
Constituents blood cells are also called corpuscles or formed elements erythrocytes = rbcs leukocytes = wbcs (5 types: monocyte, lymphocyte, eosinophil, basophil, neutrophil) thrombocytes = platelets blood is filtered at the glomerulus. When weather is very warm, there is increased blood flow to the surface, resulting in warmer skin and faster heat loss. When weather is cold, blood flow focuses more on the important organs deep in the body to maintain heat. The blood can regulate acidity/alkalinity through lungs and kidneys. In the lungs, carbon dioxide dissociates into carbonic acid causing a low ph (high acidity). Lungs respiratory compensation good for short term. Acidosis (low ph) can be fixed by lowering the co2 levels by hyperventilating. Alkylosis (high ph) can be fixed by increasing co2 levels by slowing down the breathing but be careful not to get hypoxia (lack of oxygen) Kidneys metabolic compensation good for long term. Acidosis (low ph) can be fixed by excreting h+ and keeping hco3-
