RESPIRATORY AND CARDIOVASCULAR
CARDIOVASCULAR ANATOMY
herart
morphology
conical; size larger than a fist; It has 4 chambers namely atrium dexter, sinister and ventricle dexter, sinister
location
thoracic cavity between the right and left lungs
structure
auricula cordis
septum atriak
septum interventriculum
musculus pappilaris
bloodvessel
channel through which blood will flow and distribute from the heart throughout the body and will return to the heart
there are 4 main bloodvessel namely:
vena cava sup/inf
vena pulmonalis
arteri pulmonalis
aorta
blood
transport medium containing material to be delivered to the body. contains carbon dioxide, oxygen and nutrients
PHYSIOLOGY OF HEART
circulatory system connected to the heart namely:
pulmonary: circulation: heart--> lungs
systemic circulation: heart--> organs system
step
CO2 blood --> vena cava sup/inf --> atrium dexter --> katup trikuspid --> ventrikel dexter --> katup seminular pulmonary --> arteri pulmonary --> paru-paru --> darah O2
darah O2 --> vena pulmonalis sup/inf --> atrium sinistra --> katup bikuspid --> ventrikel sinistra --> katup seminular aortic -->aorta --> seluruh tubuh
STARLINGS LAW
"Stroke volume is affected by end-diastolic ventricular volume"
During diastole, the ventricles fill with blood from the atria. the more blood is filled into the ventricles during diastole, the greater the end-diastolic ventricular volume.
BLOODSTREAM SYSTEM
artery
vessels that carry blood away from the heart.
structure
tunica interna
tunica media
tunica adventtia
Arteries carry blood that contains a lot of oxygen
vein
vessels that carry blood to the heart.
The veins are located near the surface of the body and appear bluish
Veins have valves along the length of the vessels
structure
tunica interna
tunica media
tunica advetia
capillary
Capillaries are only composed of a single layer of very thin endothelial cells and function for the exchange of substances.
FACTORS AFFECTING BLOOD PRESSURE
gender
age
sport
weight
family history
drugs
race
BLOOD PRESSURE REGULATION
Blood pressure in the body is influenced by cardiac output, peripheral resistance, volume, blood viscosity, and elasticity of the walls of blood vessels.
when the homeostatic state of the body is disrupted, it will result in a decrease in blood volume and blood pressure. Through regulation by the sympathetic nerves with a short time interval will increase cardiac output and peripheral vasoconstriction
