The correct sequence of parts that carry cardiac impulses is - ANS SA node, AV node, AV bundle, Purkinje fibers Which plasma protein is accurately described? - ANS Beta globulins-transport of lipids and fat-soluble vitamins In an ECG pattern, the P wave is caused by - ANS depolarization of atrial muscle fibers. The systemic circuit - ANS sends oxygen-rich blood to the tissues. Secretions that affect only nearby cells are termed - ANS paracrine. The pulmonary circuit - ANS sends oxygen-poor blood to the lungs. Formed elements" are - ANS blood cells and platelets. Exocrine glands differ from endocrine glands in that exocrine glands - ANS secrete through ducts or tubes to the body's exterior.
