Lanjut…st.kardiovaskuler

 Sistem kardiovaskuler berfungsi mengedarkan darah ke seluruh tubuh, membawa oksigen dan gizi ke semua jaringan tubuh dan mengangkut semua zat buangan

JANTUNG

1. Dindingnya terdiri atas 3 lapis yaitu: Perikardium, merupakan selaput pembungkus jantung Miokardium, merupakan otot jantung Endokardium, merupakan selaput yang membatasi ruangan jantung 2. Ruangan jantung: Jantung mempunyai 4 ruangan jantung yaitu : a. 2 serambi (atrium) yaitu atrium sinister / kiri dan atrium dekster / kanan b. 2 bilik (ventrikel) yaitu vebtrikel sinister / kiri dan ventrikel dekster / kanan

jantung

3. Klep jantung Antara ruang jantung dihubungkan oleh klep atau katub jantung seperti: 1 . valvula trikuspidalis = klep jantung berdaun tiga yang terletak antara atrium kanan dengan ventrikel kanan

2. Valvula bicuspidalis

= klep jantung berdaun dua, terletak antara atrium kiri dengan ventrikel kiri Jantung juga memiliki korda tendinae yaitu urat jantung yang menjaga katup (klep) jantung mendapat makanan dan O2 dari nadi tajuk (arteri coronaria) Otot jantung termasuk otot involunter yang bekerja di luar kendali sistem koordinasi.

Kelistrikan jantung

1.S.A node sbg pemicu timbulnya aksi potensial (pace maker). Terletak di dinding anterior RA berdekatan dengan tempat masuknya vena cava sup.

2.A.V node terletak pada septum atrium bagian kanan dan sedikit posterior katup triskupidalis/ dekat muara sinus koronarius 3.Berkas His, lanjutan dari AV node, merupakan penghubung fungsional antara otot atrium dan ventrikel, kemudian bercabang menjadi left and right bundle branch. Kemudian ke serat serat purkinye yang berada di sel-sel miokardium.

jantung

  Jantung berfungsi sebagai pompa darah ke seluruh tubuh Dari seluruh tubuh, darah mengalir 

vena cava superior dan inferior

atrium,  right ventrikel melalui tricucpidalis valve, yang memompa darah ke arteri pulmonalis menuju paru. Pada paru terjadi proses pertukaran gas sehingga darah yang teroksigenasi left atrium    vena pulmonalis

right

 mitral valve  left ventrikel melalui darah dipompa ke aorta  ke seluruh tubuh.

Pembuluh darah

   Pembuluh darah merupakan keseluruhan sistem peredaran (sistem kardiovaskuler) terdiri dari arteri, arteriola, kapiler, venula dan vena. Pembuluh arteri berdinding tebal, berotot, dan elastis untuk menahan tingginya tekanan darah yang dipompa dari jantung. Vena yang membawa darah kembali ke jantung, berdinding lebih tipis dan mudah teregang, memungkinkannya mengembang dan membawa darah berjurnlah besar saat tubuh sedang beristirahat. Dinding dalam pada banyak vena mempunyai lipatan yang berperan sebagai katup searah untuk mencegah darah bergerak ke arah yang salah.

A localized abnormal dilation of a blood vessel, usually an artery, caused by weakness of the vessel wall; may eventually burst A feeling of constriction around the heart or pain that may radiate to the left arm or shoulder, usually brought on by exertion; caused by insufficient blood supply to the heart The development of fatty, fibrous patches (plaques) in the lining of arteries, causing narrowing of the lumen and hardening of the vessel wall. The most common form of arteriosclerosis (hardening of the arteries). Root ather/o means “porridge” or “gruel.” A slow heart rate of less than 60 beats per minute Sudden damage to the brain resulting from reduction of blood flow.

Bluish discoloration of the skin caused by lack of oxygen Thrombophlebitis involving the deep veins

Terminology diaphoresis dissecting aneurysm dyslipidemia dyspnea edema embolism fibrillation Meaning

Profuse sweating An aneurysm in which blood enters the arterial wall and separates the layers. Usually involves the aorta Disorder in serum lipid levels, which is an important factor in development of atherosclerosis. Includes hyperlipidemia (high lipids), hypercholesterolemia (high cholesterol), hypertriglyceridemia (high triglycerides) Difficult or labored breathing (-pnea) Swelling of body tissues caused by the presence of excess fluid.

Causes include cardiovascular disturbances, kidney failure, inflammation, and malnutrition.

Obstruction of a blood vessel by a blood clot or other matter carried in the circulation Spontaneous, quivering, and ineffectual contraction of muscle fibers, as in the atria or the ventricles

Terminology heart block heart failure hemorrhoid hypertension infarct ischemia murmur Meaning

An interference in the conduction system of the heart resulting in arrhythmia A condition caused by the inability of the heart to maintain adequate circulation of blood A varicose vein in the rectum A condition of higher-than-normal blood pressure. Essential (primary, idiopathic) hypertension has no known cause An area of localized necrosis (death) of tissue resulting from a blockage or a narrowing of the artery that supplies the area Local deficiency of blood supply caused by obstruction of the circulation (root hem/o) An abnormal heart sound

Terminology myocardial infarction (MI) occlusion phlebitis plaque rheumatic heart disease Meaning

Localized necrosis (death) of cardiac muscle tissue resulting from blockage or narrowing of the coronary artery that supplies that area.

Myocardial infarction is usually caused by formation of a thrombus (clot) in a vessel A closing off or obstruction, as of a vessel Inflammation of a vein A patch. With regard to the cardiovascular system, a deposit of fatty material and other substances on a vessel wall that impedes blood flow and may block the vessel. Atheromatous plaque.

Damage to heart valves after infection with a type of streptococcus (group A hemolytic streptococcus). The antibodies produced in response to the infection produce scarring of the valves, usually the mitral valve.

Terminology shock stenosis stroke syncope tachycardia thrombophlebitis thrombosis thrombus Meaning

Circulatory failure resulting in inadequate supply of blood to the heart. Cardiogenic shock is caused by heart failure; hypovolemic shock is caused by a loss of blood volume; septic shock is caused by bacterial infection Constriction or narrowing of an opening See cerebrovascular accident A temporary loss of consciousness caused by inadequate blood flow to the brain; fainting An abnormally rapid heart rate, usually over 100 beats per minute Inflammation of a vein associated with formation of a blood clot Development of a blood clot within a vessel A blood clot that forms within a blood vessel (root thromb/o)

Commonly accomplished by surgically removing plaque, inflating a balloon within the vessel, or installing a device (stent) to keep the vessel open.

A battery-operated device that generates electrical impulses to regulate the beating of the heart. It may be external or implanted, may be designed to respond to need, and may have the capacity to prevent tachycardia Correction of an abnormal cardiac rhythm. May be accomplished pharmacologically, with antiarrhythmic drugs, or by application of electric current (see defibrillation) Radiographic study of the coronary arteries after introduction of an opaque dye by means of a catheter Surgical creation of a shunt to bypass a blocked coronary artery. The aorta is connected to a point past the obstruction with another vessel or a piece of another vessel, usually the saphenous vein of the leg or the left internal mammary artery

Terminology Meaning defibrillation percutaneous transluminal coronary angioplasty (PTCA)

Use of an electronic device (defibrillator) to stop fibrillation by delivering a brief electric shock to the heart. The shock may be delivered to the surface of the chest or be delivered directly to the heart through wire leads.

echocardiography (ECG) lipoprotein

A noninvasive method that uses ultrasound to visualize internal cardiac structures electrocardiography Study of the electrical activity of the heart as detected by electrodes A compound of protein with lipid. Lipoproteins are classified according to density as very low density (VLDL), low density (LDL), and high density (HDL). Relatively higher levels of HDLs have been correlated with health of the cardiovascular system.
