- Heart-lung machine
- Absolute refractory period
- Plateau Phase
- Cervical and Upper thoracic sympathetic chain ganglia
- a Temporarily substitutes for a patient's heart and lungs. It oxygenates the blood, removes carbon dioxide, and pumps blood throughout the body.
- b Prolongation of the depolarization phase of a cardiac muscle cell membrane; results in a prolonged refractory period. A prolonged period of slow repolarization.
- c flaplike, are extensions of the atria that can be seen anteriorly between each atrium and ventricle
- d The Cardiac muscle cell is completely insensitive to further stimulation. Portion of the action potential during which the membrane is insensitive to all stimuli, regardless of their strength.
- e which project to the heart as cardiac nerves.
5 Multiple choice questions
- The space between the visceral and parietal pericardium, is filled with a thin layer of serous pericardial fluid.
- depolarization also causes these channels to begin to open.
- branches from the pulmonary trunk, which carry blood to the lungs, where carbon dioxide is released and oxygen is picked up.
- is medial to the opening of the superior vena cava. Mass of specialized cardiac muscle fibers; acts as the "pacemaker" of the cardiac conduction system.
- Either one of the tenth pair of cranial nerves, consisting of motor fibers that innervate the muscles of the pharynx, larynx, heart, and thoracic and abdominal viscera, and of sensory fibers that conduct impulses from these structures to the brain.
5 True/False questions
Venous return → Either one of the tenth pair of cranial nerves, consisting of motor fibers that innervate the muscles of the pharynx, larynx, heart, and thoracic and abdominal viscera, and of sensory fibers that conduct impulses from these structures to the brain.
Right and left bundle branches → has 3 major openings: The openings from the superior and inferior vena cava receive blood from the body, and the opening of the coronary sinus receives blood from the heart itself.
Cardiopulmonary resuscitation (CPR) → carries blood to the lungs and returns it to the left side of the heart.
Nitroglycerin → The heart stimulates itself (auto) to contract at regular intervals (rhythmic).
Atria → thin- walled, form the superior and posterior parts of the heart.
