Heart/Cardiovascular System

Heart Intro

100

This covering of the heart lines the pericardial cavity

Parietal Pericardium

200

This wall of the heart is the most superficial layer

Epicardium

300

These chambers receive blood returning to the heart

Atrium

400

This valve separates the right atria and ventricle and 3 cusps.

Tricuspid Valve

500

Bicuspid Valve-->Left Ventricle-->___(Valve)___

Aortic Valve

Arteries/Veins/Capillaries

100

This describes the type of circulation from the heart, out to the body, back to the heart

Systemic Circulation

200

This describes the vessels that have a small lumen and thick walls, providing oxygenated blood.

Arteries

300

This provides blood to the actual vessel walls

Vaso Vasorum

400

This type of capillary is the most leaky

Sinusoid

500

This layer of vessel is described as the middle layer, is composed of smooth muscle, and is where vasodilation and vasoconstriction occurs.

Tunica Media

Blood

100

This is the function of blood that describes oxygen and nutrients being circulated throughout the body

Transport

200

This part of blood is responsible for the body's delivery system of gas exchange. They cells are biconcave, non-nucleated, and serve as a home for the Hemoglobin 

Erythrocytes (RBCs)

300

This part of blood is 90% water, gases, organic substances (proteins), and Inorganic substances (Ions)

Plasma

400

This part of blood does not have a nucleus and its main function is Hemostasis.

Thrombocytes (Platelets)

500

This is the stem cell that is responsible for forming all blood cells

Hemocytoblast

Blood Flow

100

This is the force exerted by blood upon the walls of the blood vessels or chambers of the heart

Blood Pressure

200

These are the soft ticking sounds that blood flow through vessels makes.

Korotkoff Sounds

300

This is the lower value of blood pressure, that represents the pressure of blood during ventricular relaxation.

Diastolic BP

400

This factor affecting blood flow and blood pressure deals with the ability of the vessels to stretch to accommodate volume

Compliance

500

Driven by capillary hydrostatic pressure, this describes the movement of fluid from an area of higher pressure in the capillary bed, to an area of lower pressure in the tissues.

Filtration

Blood Regulation

100

This is responsible for the stimulation of "fight or flight"

Sympathetic Nervous System

200

Neurological regulation of blood pressure and flow depend on the cardiovascular centers located in this part of the brain

Medulla Oblongata

300

This component of your neural regulation of blood slows cardiac function by decreasing heart rate and stroke volume via parasympathetic stimulation

Cardioinhibitory centers

400

These are stretch receptors, located within areas of blood vessels and heart chambers, send impulses to the cardiovascular centers in the brain

Baroreceptors

500

This form of regulation only enhances body's "fight or flight" and involves many hormones, including epi and norepi.

Endocrine Regulation
