Hormone
What gland secretes hormones directly into the bloodstream?
Endocrine
What is pulse?
Alternating surges in pressure in an artery caused by contraction and relaxation of left ventricle
What is blood predominantly made up of?
Name one of the heart valves
Mitral (bicuspid), Aortic, Pulmonary, Papillary muscle, Tricuspid, Chordae tendineae, Trabeculae carneae
Word for when there is a quivering or irregular heartbeat (arrhythmia)
Fibrillation
What is the effect of growth hormone in the body
Stimulates growth and protein synthesis, mobilizes fat and conserves glucose
What is the average heart rate and length of cardiac cycle?
Average 75bpm and cardiac cycle of 0.8seconds
Formed element in blood which is spherical, nucleated cells which make up WBCs
Leukocyte
Node in heart which initiates impulses
Sinoatrial (SA) node
Wave in ECG which shows atrial depolarization initiated by SA node
P wave
What are the hormones which are stored in the posterior pituitary gland?
Oxytocin, Antidiuretic hormone (ADH)
What is diastole and systole?
Diastole: heart muscles relax and allow chambers to fill blood. Systole: heart muscles contract and empty chamber
What are the antigens and antibodies present in type O blood

Name a pulse point
Superfical temporal artery, Facial artery, Common cartoid artery, Brachial artery, Radial artery, Femoral artery, Popliteal artery, Posterior tibial artery, Dorsalis pedis artery.
Basophil
What heart structure depolarizes the contractile cells of both ventricles allowing for ventricular contraction
Purkinje Fibers
Segment in ECG where ventricular depolarization is complete
ST segment
What part of the anterior pituitary gland produces growth hormone and prolactin
Acidophils
What are the sounds of of Korotkoff and the pressures that correspond with each sound?

Cytoplasmic fragments in blood that contain granules, stain deep purple and play a big role in blood clotting
What is the electric connection between the atria and ventricles
AV bundle
Wave in ECG that is caused by ventricular replorization begining in the apex
T wave
