WebOverview; On the most fundamental level systemic arterial pressure is dependent on the cardiac output and systemic vascular resistance. Recall from hemodynamic integration that for any vascular system the blood pressure gradient = (Blood Flow Volume) x Resistance.The application of this equation to the entire systemic circulation allows for a … WebInspiration (inhalation) is the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction. During inspiration, the diaphragm contracts and the thoracic cavity increases in volume. This decreases the intraalveolar pressure so that air flows into the lungs.
