(Cardiovascular System)
Salvador Ramos Per.5
Structural and functional differences between blood vessel types(arteries, veins, capillaries)
Veins
flap-like valve
thinner muscle layer
Connreturn blood toward heart
Doesn't carry high-pressure blood
Capllaries
1 layer of endothelium
connects aterioles and venules
Smallest blood vessel
Arrteries
Carries blood away from heart
strong/elastic
Take blood to tissues and back
Carrying high-pressure blood
Smaller as they divide
Cardiac Cycle and the ECG
ECG
QRS Complex: depolarization of ventricle and repolarization of atria
Electrocardiogram (ECG)
P wave: depolarization of atria
T wave: repolarization of ventricles
Electrical signals
Cardiac Cycle
Subdivided: Contraction phase
Cycle is 0.8 seconds long
Heart beat regular and rhythmic
DIastole: Relaxation phase
72 beaste per minute
Blood flow through the heart and body
Steps:
Step 1: Blood from the upper andlower body flows throught the Superior and Inferior vena cave inot the right atrium
Step 2: Blood passes the tricuspid valve into the right ventricle
Step 3: Blood passes the Pulmanary valve into the pulmonary artery
Step 4: Bloof from the Pulmonary artery leaves the heart to the left and right lungs
Step 5: Blood from the left and right lungs goes into the Pulmonary veins
Step 6: Blood then goes into the left atrium
Step 7: Blood passes the mitral valve into the left ventrilce
Step 8: Blood passes through the Aortic valve into the Aorta
Step 9: Blood exits the Aorta into the upper and lower body
Left side: Oxygenated Blood
Chambers, vakves, and veins
Left atrium and valve
Right Atrium and valve
Tricuspid, Pulmanary, Mitral, and Aortic valve
Right side: Deoxygenated Blood
Layers of the heart
Myocardium
Bulk of the heart and layer of cardiac muscle tissue
Location: Underneath the Epicardium
Ednocardium
Layer covers the values of the heart and chordae tendinease of the values
Location: Innermost layer of the heart
Epicardium
Protection from trauma or friction
Location: Outersurface of the heart
Anatomy of the heart (including all chambers, and valves)
Right Atrium
Right Ventricle
Left Ventricle
Tricuspid Valve
Left Atrium
Aortic Valve
Mitral valve
Pulmonary Valve
Chambers of the heart are where blood is stored and kept untill a valve opens and blood exits the chambers
The valves of the heart allow blood to flow to another area preventing blood to flow back
Disorders of the cardiovascular system
Coronary artery disease
Vital oxygen and nutrients
Plaque builds up and hardens
Heart Attack
Cause body to hold in salt and water
Doesn't pump strongly as it should
Heart Valve disease
Valves dont close well
Aortic valve narrows causing slow blood flow
Valves form upper and lower valves dont close fast enough
Arrhythmias
Unusaul heart beat sound
Heart beat slow/fast
Major Functions of the Cardiovascular System
Blood Vessels
Network of tubes
Capillaries
Veins
Arteries
Where the blood flows
Blood
Different types of blood groups
Different types
Liquid that flows througout the body
The Heart
High connected cells
4 chambers
Right Ventricle
Left Atrium
Right atrium
Left Ventricle
Cardiac muscle tissue
