Document Summary
Epithelia: line and cover, highly cellular. Connective tissue: support, significant non-cellular component. Nerve: electrical an chemical communication, excitable. Key to physical characteristic (fluidity) due to plasma. Plasma is not secreted by blood cells and many consider it a tissue. Live for ~120 days: protein an fe recycled by liver. Respiratory gas transport: hemoglobin, 4fe/hb, 15gm/dl. Percentage of red cells: cv/(cv+pv)x100, males: 46, females: 41. High- polycythemia: high altitude, blood doping, erythropoietin (epo) Outcome is that beyond a certain point there is no advantage to increasing the o2 carrying capacity of blood. Types of microorganisms: bacteria, viruses, protozoans, worms, fungi. Bacteria: prokaryotes, reproduce rapidly, come in many varied morphologies, many of the pathogenic bacteria injure tissue through the secretion of toxins. Proper identification of the type of bacteria is critical to proper treatment as antibacterials are specific to different kinds of bacteria. Well known bacterial diseases include: cholera, anthrax, bubonic plague, venereal diseases: syphilis and gonorrhea, tuberculosis, lyme disease.
