Myocardium

Cardiac Muscle

In what order does blood flow through the heart

Right atrium, tricuspid valve, right ventricle, pulmonary artery, lungs, pulmonary vein, left atrium, Mitral valve, left ventricle , aorta.

Right atrium receives blood from which three sources?

1. Superior Vena Cava- above the heart

2. Inferior Vena Cava- below the heart

3. Coronary Sinus- blood from the veins of the heart muscle

Diastolic

The pressure in the arteries

Systolic

The pressure generated in the arteries

bradycardia

below 60 bmp

tachycardia

greater then 100 bmp

SA node (Sinoatrial)

located in the right atrium and acts as the hearts pacemaker. Rhythms that start from impulses in the SA node are called sinus rhythms.

AV node (Atrioventricular)

located between the atria and ventricles. Transmits electrical impulses to bundle of His. The bundle of His branches into the right and left ventricles which carry the impulse from the AV node stimulating the contraction of the ventricles.

Brachiocephalic artery

branches into right common carotid artery

Lingual artery

supplies the tongue and floor of mouth

facial artery

starts behind the angle of the mandible and wraps around the inferior border of the mandible and travels back up to the face supplying it with blood

Maxillary artery

basic supply to the face

Antecubital space

anterior surface of elbow

Pharynx

space between the nose and trachea

Nasopharynx

part above the back of the soft palate

oropharynx

lies between soft palate and epiglottis

Epiglottis

soft tissue valve that covers the larynx (voice box), allows air in and out of longs and prevents food or liquids to enter lungs

Laryngopharynx

behind the larynx (voice box)

Dead space

area which gases are not exchanged. extends from the pharynx to bronchioles. 150cc in average adult. Adult intakes 500 cc of air but only 350cc reaches alveoli and is available for gas exchange.

Medulla Oblongata

controls respiration

Central Nervous System

consists of brain and spinal cord.

Cerebrum and Cerebellum

Cerebrum- thought area

Cerebellum-motor area

Peripheral Nervous System

Sensory nerves-recieve the message/response and motor nerves- carry out the response

Autonomic Nervous System

Sympathetic "fight or flight"

Parasympathetic "rest and digest"

P wave

Atrial depolarization

QRS complex

Ventricular depolarization

T wave

Ventricular repolarization

Dysrhythmias

abnormal rhythms
