Intestine to liver
Hypophyseal portal system connects _______ to _____
Hypothalamus to pituitary gland
What supplies heart with oxygen and nutrients
Coronary arteries
Where is sinoatrial node
In right atrium
Where is apex
Near ventricles at the bottom
Which heart is more muscular
Left
Bicuspid is where
Left atrium
Tricuspid is in the
Right atrium
Diastole
Ventricles relax
Systole
Ventricles contract
Mechanism of how the heart contracts
Impulse activates SA node which activates AV node which activates bundle of his which activates purkinje fibers.
AV node is delayed to
Allow ventricles to fill
Parasympathetic neurotransmitter slow the heart by
The vagus nerve
