Ricky Garcia-Period 7-Cardiovascular system
Disorders
Heart Conditions: Abnormal Heart rythems. Aortic Diseases.
Coronary Artery Disease (narrowing of Arteries)
Other Heart conditions: Heart Attack, Heart Failure, Heart muscle disease.
Vital Signs (BP and Pulse)
Blood pressure is defined as systolic and diastolic.
Diastolic: The time when the Heart gets its blood and Oxygen, A normal Diastolic rate would be 80 or lower
Systolic: Your Optimal Blood Pressure levels which is defined as 120, the pressure your heart beats at.
Cardiac Cycle and the ECG
ECG- Electrocardiogram, A recording of electrical changes that occur during the cardiac cycle.
Cardiac cycle, When the heart bumps its ventricles contract the AV valves close. After the second Bumb the ventricles Relax and the Aortic and Pulmonary Valve closes.
Layers of the Heart
Myocardium- Middle, pumps blood out of Heart chambers
Endocardium- Innermost, Connective Tissue and Epithelial Tissue hold Purkinje Fibers together.
Epicardium- Outer, decerases friction within the Heart
Major Blood vessels (Arteries and Veins)
Arteries: Transport Blood Away from the Heart to be re-oxygenated.
Veins- Transports Oxygenated Blood to the Heart in order for the heart to deliver it to the lungs. The cycle repeats.
Structural and Functional differences between blood vessel types (Arteries, Veins, and Capillaries)
Arteries: Arteries Carry high pressure blood and Transport Blood away from the heart.
Veins: Contains Venules that emerge from capillaries and merge to them from a larger vein.
Capillaries: Blood vessels with small diameters, aids in constant exchanges of respiratory gases.
Blood flow through the heart and Body
Blood enters through the Inferior vena cava and then enters into the Right Atrium through the Tricuspid valve.
Ventricles push blood through the Pulmonic valve into the Pulmonic Artery.
Blood is then sent to the Aorta where blood is distributed to the rest of the body through blood vessels.
Major Components and Functions of Blood
Major Components: Plasma, RBC, WBC, and Platelets.
Functions: Transporting Oxygen and nutrients to the lungs and Tissues. Form Blood clots to prevent extreme Blood Loss.
Major Functions of the Cardiovascular system
Allow for the Body to transport Blood, Oxygen, and Nutrients around the body for daily function.
The Cardiovascular system is also capable of removing Carbon dioxide and waste from our bodies.
ABO, Rh Blood types
ABO Blood Groups
B Blood, B antigen, Anti- A in Plasma
AB Blood, A & B Antigen, No Anti-Bodies
A Blood, A antigen Anti-B in plasma
O Blood, No Anti-Gun, Both Anti-Bodies
Most common Antigen- Antigen D
RBC- If present in RBC- Rh Positive. If Absent- Rh Negative
Anatomy of the Heart
4 Chambers:
2 upper- Atriums
2 lower- Ventricles
