Cardiovascular System- Alicia Resmer, Period 5 - Coggle Diagram
Cardiovascular System- Alicia Resmer, Period 5
Anatomy of the Heart
Sup and Inf Vena Cava, Pul vein and art, L and R Atrium, L and R Ventricle, Pul valve, aortic valve, tri and bi valve, aorta
Major Components and functions of blood
WBC
Attack invaders such as bacteria and viruses
Platelets
Prevent and stop bleeding
RBC
~45% of blood, carry oxygen, transport waste such as carbon dioxide
Plasma
Mostly Water, ~55% of blood, takes nutrients, hormones and proteins to parts of the body that needs it
Sum it up Functions
regulate body temp, bring waste to liver and kidneys, prevent blood loss thru clots, transport oxygen and nutrients
Cardiac Cycle and the ECG
Atrial systole, vent systole, atrial diastole, vent diastole
ECG: graphic recording of electrical activity
P Wave: Depol of SA node and atria
P-R Interval: Begin of atrial excitation to begin of ventri excitation
S-T Seg: entire ventri myocardium depol
QRS Complex: Ventri depol and Atrial repol
Q-T interval: begin of ventricular depol through ventricular repol
T wave: Ventri repol
Disorders of the cardiovascular system
Heart Attack (Myocardial Infarction)
Nausea, Chest pain (tight), Discomfort that spreads, Cold Sweat, Fatigue, Dizziness
Blood flow to heart is reduced or blocked
Stroke
Trouble speaking/understanding, numb/weak, Severe headache, trouble seeing, dizzy, facial droop
Blood flow to brain is reduced of blocked
Congenital Heart Disease
Cyanosis, swelling in tummy or legs, rapid breathing, rapid HR,
Birth Defect that affects how heart works
Peripheral Artery Disease
One colder foot, toe nails and hair might stop growing, Cramping in legs
Buildup of fatty deposit in arteries
Endocarditis and Myocarditis
Aching joints and muscles, fatigue, chest pain when breathing, shortness of breath, abnormal heart sounds, swelling in feet legs belly
viral infection that weakens heart
Major Blood Vessels (names arteries and veins)
Arteries: Ascending Aorta, Aortic Arch, Thoracic Aorta, Abdominal Aorta, Brachiocephalic Trunk, Common Carotid, Subclavian, Axillary, Brachial, Radial, Ulnar, Common illiac, Femoral, Anterior Tibia, Fibular
Veins: Cephalic, Basilic, Radial, Ulnar, Brachial, Axillary, Subclavian, Brachiocephalic, Superior and Inferior Vena Cava, Internal Jugular, External Jugular, Femoral, Great Saphenous, External Internal and Common illiac,
Vital Signs (BP and Pulse)
Normal Vital Signs: 98.6 for temp, 60-100 beats/min HR, 12-18 Breaths/Min RR, 95-100% Blood Oxy, BP 120/80
Vital Signs: Body Temp, Blood Pressure, Heart Rate, Respiratory Rate, Pain
Pulse Points: Temporal, Carotid, Apical, Radial, Brachial, Femoral, Popilteal, Anterior Tibial, Posterior Tibial, Dorsalis Pedis

If you receive the wrong blood, good luck LOL
Major Functions of the Cardiovascular System
Made up of heart, blood, blood vessels
Transport nutrients, Remove Waste, Fight Diseas
Layers of the Heart
Epicardium
Epithelial cells covering surface (Outer Layer)
Protects Heart, Makes sure cardiac cells properly develop, Prper response to cardiac cell injury
Myocardium
Middle Layer
Contractile function (Cardiac Pump), Produce rhythmic, wave like functions that is the heartbeat
Endocardium
Innermost Layer
Lines valves, tissue covering the inside of heart, keeps blood flowing separate from myocardium
Structural and functional differences between blood vessel types (arteries, veins,
capillaries)
Veins have thinner walls + valves to prevent backflow, Arteries carry blood away while veins carry towards heart, Capillaries transport blood between veins and arteries (smallest blood vessel), Arteries have thicker walls to withstand higher pressure, Arteries have more narrow lumen
Blood Flow through the heart and body
Deoxy Blood > S and I Vena Cava > Right Atrium > Tricuspid Valve > Right Vent > Pul SL valve > Pul Trunk > S and L pul art> Gain Oxy > R and L lungs > Pul veins > Left Atrium > Bicuspid or Mitral Valve > Left Vent > Aortic SL valve> Aorta > Body > Lose oxy > Back to S and I vena cava
