BMS 360 Lecture Notes - Nitric Oxide, Shear Stress, Thoracic Cavity
Document Summary
Exercise increased release of metabolites, decreased o2 levels. Lactic acid, atp, k+ ions, h+ ions, co2. Increase in blood flow as a result through arteriolar dilation. Most of the blood in the body is present in veins. Major function regulation of cardiac output through venus return. Compliance of veins is much greater than that of arteries. During respiratory inspiration, vr increases because of a decrease in right atrial pressure. Breath in diaphragm drops pressure in thoracic cavity drops. Enable the exchange of water, o2, co2, nutrients, and waste substances between blood and surrounding tissues. Understand that endothelial dysfunction is associated with cardiovascular disease. Identify the three main classes of endothelium-dependent vasodilators, how each is produced, and how each is thought to elicit smooth muscle cell relaxation. Single cell layer lining the lumen of all blood vessels (collectively called the endothelium) Have receptors for a wide range of hormones, autocrine and paracrine factors.
