4. Heart +circulatory system =cardiovascular system
5. Cardiovascular System consist of
1. Heart
2. Blood Vessels
3. Blood
6. Functions of cardiovascular system
Pumping blood to the body tissues and cells
Supplying oxygen and nutrients to tissues and cells
Removing carbon dioxide and other waste products of metabolism from tissues and cells
7. Layer of heart
Pericardium outer
Myocardium-- middle
Endocardiuminner
8. Heart chambers
right atrium
Left atrium
Right ventrical
Left ventrical
9. Valve of heart
10. The tricuspid valve regulates blood flow between the right atrium and right ventricle
The pulmonary valve controls blood flow from the right ventricle into thepulmonary arteries, which carry blood to the lungs to pick up oxygen
The mitral valve lets oxygen-rich blood from the lungs pass from the left atrium into the left ventricle
The aortic valve opens the way for oxygen-rich blood to pass from the left ventricle into the aorta, the body's largest artery, where it is delivered to the rest of your body
11. Tricuspid valve- located between the right atrium and the right ventricle.
Pulmonary valve- located between the right ventricle and the pulmonary artery.
Mitral valve- located between the left atrium and the left ventricle.
Aortic valve- located between the left ventricle and the aorta.
12. heart valves function
When the left ventricle relaxes, the aortic valve closes and the mitral valve opens, to allow blood to flow from the left atrium into the left ventricle.
The left atrium contracts, allowing even more blood to flow into the left ventricle.
When the left ventricle contracts again, the mitral valve closes and the aortic valve opens, so blood flows into the aorta.
13. Blood vessels
Blood vessels are intricate network of hollow tubes that transport blood throughout the body
14. Types of blood vessels
Arteries red blood vessels that carry blood away from the heart
Veins blood vessels that caarry blood towards the heart
Capillaries which links the arteries and veins.
15. Arteriesveins
Transport blood from thetransport blood towards
Heart the heart
Carry oxygenated bloodcarry deoxygenated blood
Narrow lumenswide lumens
More elastic muscle less elastic muscles
16. Transports blood undertransports blood under
Higher pressure lower pressure
Do not have valveshave valves to prevent
(except for the semi-lunarblood flowing to wrong
Valves of the pulmonary@ direction. to avoid return
And aorta ) waste material to the tissue
17. 18. Capillary functions
vital role in the exchange of gases,
nutrients, and metabolic waste products
between the blood and the tissue cells.
Substances pass through the capillaries wall by---
diffusion, filtration, and osmosis.
19. 20. 21. Types of circulation
Pulmonary circulation
Coronary circulation
Systemic circulation
22. In pulmonary circulation
23. In coronary circulation
24. Coronary diseas list
Congestive Heart Failure
Coronary Artery Disease
Acute Myocardial Infarction
Hypertension
Cardiac Arrhythmia
Cardiomegaly
Miscellaneous Cardiovascular Diseases
25. major risk factors that can't be changed
Increasing age
Gender
Heredity
26. major risk factors you can modify, treat or control by changing your lifestyle or taking medicine
Tobacco smoke
High blood cholestrole
Physical inactivity / Obesity and overweight
Diabetes mellitus
27. factors contribute to heart disease risk
Stress
Too much alcohol
28. Sign and symptoms
Chest pain or chest discomfort (angina)
Pain in one or both arms, the left shoulder, neck, jaw, or back
Shortness of breath
Dizziness
Faster heartbeats
Nausea (feeling sick to your stomach)
Abnormal heartbeats
Feeling very tired.
29. Diagnosis of cardiovascular system
Chest x ray
Stress test
Tilt table test
Echocardiogram
Cardiac catheterization
Electrophysiological test
Chest scan
ChestMRI
Myocardial biopsy
30. Treatment of cardiovascular system
Therapeutic treatment
Medical treatment
Surgical treat ment
31. Measurement techniques
Electrocardiogramfor cardiac electrophysiology
Sphygmomanometerandstethoscopefor blood pressure
Pulse meterfor cardiac function (heart rate, rhythm, dropped beats)
Pulsecommonly used to determine the heart rate in absence of certain cardiac pathologies
Heart rate variability-- used to measure variations of time intervals between heart beats
Nailbed blanching testtest for perfusion
Vesselcannulaorcatheterpressure measurementpulmonary wedge pressure or in older animal experiments.
