Cardiovascular System- Alicia Resmer, Period 5

Anatomy of the Heart

Major Components and functions of blood

Cardiac Cycle and the ECG

Disorders of the cardiovascular system

Major Blood Vessels (names arteries and veins)

Vital Signs (BP and Pulse)

ABO, Rh blood types

Major Functions of the Cardiovascular System

Layers of the Heart

Structural and functional differences between blood vessel types (arteries, veins,
capillaries)

Blood Flow through the heart and body

WBC

Platelets

RBC

Plasma

Mostly Water, ~55% of blood, takes nutrients, hormones and proteins to parts of the body that needs it

~45% of blood, carry oxygen, transport waste such as carbon dioxide

Attack invaders such as bacteria and viruses

Prevent and stop bleeding

Sum it up Functions

regulate body temp, bring waste to liver and kidneys, prevent blood loss thru clots, transport oxygen and nutrients

Made up of heart, blood, blood vessels


Transport nutrients, Remove Waste, Fight Diseas

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

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

If you receive the wrong blood, good luck LOL

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

Epicardium

Myocardium

Endocardium

Epithelial cells covering surface (Outer Layer)

Protects Heart, Makes sure cardiac cells properly develop, Prper response to cardiac cell injury

Middle Layer

Contractile function (Cardiac Pump), Produce rhythmic, wave like functions that is the heartbeat

Innermost Layer

Lines valves, tissue covering the inside of heart, keeps blood flowing separate from myocardium

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

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,

Heart Attack (Myocardial Infarction)

Stroke

Congenital Heart Disease

Peripheral Artery Disease

Endocarditis and Myocarditis

Nausea, Chest pain (tight), Discomfort that spreads, Cold Sweat, Fatigue, Dizziness

Trouble speaking/understanding, numb/weak, Severe headache, trouble seeing, dizzy, facial droop

Cyanosis, swelling in tummy or legs, rapid breathing, rapid HR,

Aching joints and muscles, fatigue, chest pain when breathing, shortness of breath, abnormal heart sounds, swelling in feet legs belly

One colder foot, toe nails and hair might stop growing, Cramping in legs

Blood flow to heart is reduced or blocked

Blood flow to brain is reduced of blocked

Birth Defect that affects how heart works

viral infection that weakens heart

Buildup of fatty deposit in arteries

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
