BIOL 155 Lecture Notes - Lecture 86: Homeostasis, Antibody, Osmotic Pressure
Document Summary
Cardiovascular disease prevention: your lifestyle has a big impact on the health of your heart, preventable risk factors include, use of tobacco products, drug and alcohol abuse, obesity and a sedentary lifestyle, poor diet, stress, poor dental hygiene. What are the functions of blood: transportation, oxygen, nutrients, wastes, carbon dioxide, hormones, defense, against invasion by pathogens, regulatory functions, body temperature, water-salt balance, body ph, homeostasis, nice point where everything works well. There are 2 cardiovascular pathways in the body: pulmonary circuit, exchange of gases, systemic circuit, exchange with interstitial fluid. How does exchange happen in a capillary bed: osmotic pressure, concentrations of dissolved particles in the, blood, tissues, blood pressure, force by which blood is being moved through the blood vessels. What is the composition of blood: formed elements, produced in red bone marrow, red blood cells (rbcs, erythrocytes, transfer, oxygen, carbon dioxide, white blood cells (wbcs, leukocytes, release antibodies, munch up bacteria, platelets, thrombocytes.
