Control of afferent arteriole blood flow helps keep a constant GFR over a wide range of mean arterial blood pressure. Carbamino is formed by CO 2 binding to hemoglobin for transport from tissues. H 2 CO 3 is the predominant form of CO 2 carried in blood. Relaxation of diaphragm reduces thoracic volume and raises alveolar pressure to force air out of the lungs.
Vasodilation causes increased ultrafiltration across the capillary bed.
An increase in nitric oxide causes relaxation of vascular smooth muscle. The functional residual capacity is the sum of the inspiratory reserve volume, the tidal volume and the expiratory reserve volume. Explain why the lymphatic system is required for blood circulation. Fill in the following table for the effect of an increase in carotid sinus pressure. Be sure to draw a labeled diagram to illustrate your answer.
