3 Types of Capillaries
System of Blood Vessels that Carries blood from the Right Ventricle of the Heart to the Lungs and back to the Left Atrium of the Heart
The System of Vessels that carries blood from the Left Ventricle of the Heart to the Tissues of the Body and back to the Right Atrium
Carries blood away from the Heart
Passes superiorly from the Left Ventricle, Right and Left Coronary Arteries
Also called Conducting Arteries
Thin Transparent layer of the heart wall
Thin layer of the endothelium overlying a thin layer of connective tissue.
Makes up about 95% of the Heart and it is responsible for its pumping action
Four Chambers of the Heart
- Right Atrium,
- Left Atrium,
- Right Ventricle,
- Left Ventricle
Four Valves of the Heart
- Pulmonary Semilunar valve,
- Mitral Valve,
- Tricuspid Valve,
- Aortic Semilunar valve
Characteristics of a Cardiac Muscle
- Single Nucleus,
- has Branches,
- has intercalated disks
It is a record of electrical events in the heart.
Instrument that is developed to listen to the sounds of the heart and lungs.
Relationship between preload and strive volume.
Starling’s law of the heart
Volume of blood pumped by either ventricle of the heart each minute
Number of times the heart contracts each minute.
Mechanisms contained within the heart.
Major veins of the head and the neck
External and Internal Jugular Veins
Returns blood from the head, neck, thorax and upper limbs to the right atrium of the heart
Superior Vena Cava
When the ventricle relax, blood pressure in the arteries falls to a minimum value called
When the ventricle contract, blood is forced into the arteries, and the pressure reaches the maximum value called
The standard blood pressure for a resting young adult male for the systolic pressure
The normal platelet count per microliter of blood
The normal white blood count for every microliter of blood
Also known as the universal donor
blood type O
Precursor cells capable of dividing to produce daughter cells that can differentiate into various types of blood cells
The normal red blood count for every microliter of blood for females
4.2 million-5.4 million
