Understanding Cardiology

Cardiology

Cardiology

Cardiology is the medical science concerned with the heart and its diseases (Cardio = Heart, Logos = science)

Cardiovascular of or  Pertaining to heart and blood vessels

Cardiologists are doctors who specialize in diagnosing and treating diseases or conditions of the heart and blood vessels—the cardiovascular system

Cardiologists include

Non invasive cardiologist- uses medications and lifestyle changes to help patients with heart disease.

Invasive or  interventional cardiologists  perform procedures such as cardiac catheterizations, which     can identify heart blockages or defects that may require surgery. An interventional cardiologist is trained in both basic cardiology and interventional cardiology.

Cardiovascular surgeons, perform surgery on the heart, lungs and blood vessels.

Understanding Circulatory System

Circulatory System

The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases.

The circulatory system is comprises of two separate systems: the cardiovascular system, which distributes blood, and the lymphatic system, which circulates lymph.

Cardio – Pertaining to heart.

Thoracic – Pertaining to lungs and other nearby structures.

Vascular Central vascular – Pertains to Aorta.

Peripheral vascular – Pertaining to blood vessels in legs and hands.

Basics of Heart

Basics of Heart

The heart is located in the chest cavity, or thorax.

The heart has four chambers. The upper chambers are known as the atria and lower chambers are known as the ventricles. The ventricles are separated by muscular wall called the intraventricular septum.

 The right atrium receives blood from the veins and pumps it to the right ventricle The right ventricles pump the deoxygenated blood to the lungs The left atrium receives oxygenated blood from the lungs and pump it to the left ventricle The left ventricle pumps the oxygenated blood into the aorta, from where it is supplied to different parts of the body

The _______ receives blood from the veins and pumps it to the right ventricle

  • Right Atrium
  • Left Atrium

The right ventricles pump the deoxygenated blood to the lungs.True or False

Ranking text question

  • The right atrium receives blood from the veins and pumps it to the right ventricle
  • The right ventricles pump the deoxygenated blood to the lungs
  • The left atrium receives oxygenated blood from the lungs and pump it to the left ventricle
  • The left ventricle pumps the oxygenated blood into the aorta, from where it is supplied to different parts of the body

Blood supply to the heart

The coronary artery supply oxygenated blood to the heart muscle. Two major arteries from the aorta, branches off near the point where aorta and the left ventricle meet, they are the right and left coronary arteries.

Branches of right coronary arteries are :

 Right marginal artery. Posterior descending artery.

Branches of left coronary arteries are :

 Circumflex artery Left anterior descending artery

Heart Valves

Heart Valves

The four main valves in the heart are :

The two atrioventricular (AV) valves, the mitral valve (bicuspid valve), and the tricuspid valve, which are between the upper chambers (atria) and the lower chambers (ventricles).

The two semilunar (SL) valves, the aortic valve and the pulmonary valve, which are in the arteries leaving the heart.

The mitral valve, also known as the bicuspid valve or left atrioventricular valve, is a dual-flap valve in the heart that lies between the left atrium and the left ventricle.

Mitral Valve Disease - refers to conditions of the mitral valve. Located between the left chambers of your heart, this valve works to keep blood flowing properly.
