Cardiovascular System:- Harmanjot Singh
Disorder of cardiovascular system
Pericarditis
inflammation of pericardium
Fibrillation
Rapid uncoordinated shuddering of the heart muscles
Prevents hard from acting as a pump
Valve stenosis
Defects and values failing to open which makes heart pumping harder.
Myocardial infarction
Heart muscle cell die due to lack of blood to the heart muscles
Mumur
Abnormal or irregular heart sounds can be
caused by valve stenosis
The heart
Four Chambers
Right ventricle
Right atrium
Left atrium
Left atrium
Four valves
Atrioventricular valves
Right = triscupid valve
Left = biscupid or mitral valve
Semilunar valves
Pulmonary= omes before lungs
Aortic= comes before aorta
Heart walls
Myocardium
Endorcaridum
Epicaridum
Covered by
Layered sac
Inner layer= Visceral pericardium
Outer layer = parietal pericardium
Blood vessels
Veins
Lumens of veins are larger and to help transfer blood, use the milking action of muscles.
Arteries
Blood pumped by forced of heart and it thickest layer
Carry high blood pressure
Capillaries
Serves the respiratory system. one cell thick
The exchange of gases (nutrients and waste) between blood and tissue.
The blood
Plasma
Liquid portion of the blood
Clotting factors, hormones, antibodies, nutrients, and waste are all present.
Erythrocytes
Carry hemoglobin and oxygen
Can't repair themselves
Leukocytes
They are produced in the bone marrow and battle infection.
Five types
Neurotrophills
Lympocytes
Eosinophils
Bascophils
Monocytes
Thrombocytes
In the bone marrow, cell fragments are created. Stick together to clot blood.
Functions
Nutrients, gases, and waste products are transported across the body.
To prevent infection and blood loss in the body.
To assist the body in maintaining a stable internal temperature.
To aid in the maintenance of body fluid equilibrium.
Cardiac cycle and ECG
Hearbeat is regular and rhythmic
Each loop is divided into two sections.
Systole
Filling
Increases pressure to open valves
Diastole
Contraction
Ejection of blood
Electrocardiogram
Three deflections
P wave
T wave
QRS complex
Visible tracing of these electrical signals
Blood flow
Blood enters the right atrium
Blood flows through the triscupid valve into the right ventricle
The ventricle forces blood through the pulmonic valve into the pulmonary artery as the heart beats.
Pulmonary artery carries blood to the lungs when picks up oxygen
Oxygenated blood leaves the lungs to the return to the heart through the pulmonary vein
Blood enters the left atrium
Blood descends through the mitral valve into the left ventricle
Blood is pumped from the left ventricle into the aorta through the aortic valve.
The superior vena cava and the inferior vena cava transport blood from the body to the heart.
The vena cavas pump blood into the right atrium
The oxygenation and transport cycle starts all over again.
