atrial contraction; systole; p wave - atrial depolarization
max volume of air that can be exhaled following maximal inhalation - vital capacity
allows blood in pulmonary artery to flow directly into the descending aorta to bypass the
pulmonary circulation - ductus arteriosus

most important stimulus for the release of aldosterone - renin
volume of air in lungs following maximal inhalation - total lung capacity
provides oxygenated blood to brain - circle of willis
aorta; left pulmonary veins; left atrium; left ventricle; bicuspid - structures that carry
oxygenated blood (left heart)
pulmonary arteries; vena cava; right atrium; right ventricle; tricuspid - structures that
carry unoxygenated blood (right heart)
transport unoxygenated blood from the fetus to the placenta - umbilical arteries
transports oxygenated blood from the placenta to the fetus - umbilical vein
volume of air that remains in lung after forceful exhalation - residual volume
ventricular contraction; systole; qrs complex - ventricular depolarization
located between left ventricle and left aorta - aortic semilunar valve
located between right ventricle and pulmonary artery - pulmonic semilunar
two semilunar valves - pulmonary and aortic
pushes blood out of the heart into the pulmonary trunk-lungs - right ventricle

the liver - ductus venosus
right heart pumps blood to the - pulmonary circulation
acetylcholine; rest; decrease temp; hyperkalemia; hypocalcemia; parasympathetic
nervous system - factors that decrease heart rate
norepinephrine; epinephrine; stress; increase in temp; anticholinergic drugs;

volume of blood pumped from one ventricular of the heart with each beat - stroke
volume
volume of blood being pumped by heart, in particular by a left or right ventricle in the
time of one minute - cardiac output
vagus nerve - decreases heart rate

septum between right and left atria - foramen ovale
eliminated when we have acidosis - hydrogen ions
only structure of respiratory tract that is part of digestive system - pharynx
protein inside red blood cells that carry oxygento cells and carbon dioxide to the lungs -
hemoglobin
loss of negative intrapleural pressure - collapses lung
, !@#$%&()(^$#@#%&_)($#@#$%^&*(*&^$#
measured during normal quiet breathing - tidal volume
coronary arteries and veins are part of - systemic circulation
located between right atrium and right ventricle - right av
Lower chambers of the heart and pump blood out of the heart - ventricles
muscles of respiration relax and allow the ribs and diaphragm to return to their original
positions - exhalation
left heart pumps blood to the - systemic circulation
pushes blood out of the heart into the aorta-body - left venteicle
small hole in septum - foramen ovale
collects nutrient rich, deoxygenated blood to the liver - hepatic portal vein
excess sodium in the blood and is result of excess water loss - hypernatremia
stimulates the reabsorption of sodium and water; stimulates the excretion of potassium;
acts primarily on the distal tubule - aldosterone
forward movement of food is caused by - peristalsis
partially surround the trachea for its entire length and serve to keep it open - c-shaped
rings of cartilage
located behind the oral cavity and between the nasal cavities and the larynx - pharynx
causes bronchodilation - sympathetic ~ Epinephrine/Norepinephrine
