HUMAN HEART :
Structure :
Heart is a four chambered pumping organ which pumps blood. It's upper two chambers are known as Atria while lower two chambers ventricle. Both Atria are separated by Atrial septum and both ventricles are separated by Interventricular septum. Atria are known as recieving chambers because they collects blood. In right atrium superior and inferior vena cava opens through which blood from body comes into Heart. In right chamber opening of coronary artery (artery present in heart) also present know as Coronary Sinus. So, right atrium also recieves blood from heart itself. all blood which comes in right atrium are deoxygenated blood which means they have less amount of oxygen and very high amount of carbon dioxide. Right Atrium opens into Right Ventricle. There is a Valve present between right atrium and right ventricle know as Tricuspid Valve which checks the back flow of blood. Right ventricle pumps blood into Pulmonary Artery through which blood enters into both Lungs. In lungs oxygenation of blood occurs and now these oxygenated blood again comes into Heart (Left Atrium). Left atrium receives oxygenated blood from Lungs through Pulmonary vein. Now these oxygenated blood enters into Left Ventricle. There is a Valve present in between left atrium and left ventricle know as Bicuspid or Mitral valve. It checks the back flow of blood. Now Left ventricle pumps oxygenated blood in Aorta through which it distributed into complete body through many branches of Aorta know as Artery.
Heart has four valves. Two are Semilunar valves which are present in Pulmonary Artery and Aorta. One is tricuspid valve which is present between right atrium and right ventricle and one is Bicuspid or Mitral valve which is present between left atrium and left ventricle.
A self excitable cell also present in Right Atrium near the opening of Superior Vena Cava know as SA NODE. It generates impulse and transfers to AV NODE which further transfer to AV bundle and then Bundle of His and finally Purkinje fibres. These impulses helps in contraction in heart muscles due which heart becomes able to pump blood. When heart contracts blood from both atria enters into ventricle and blood from ventricle pumps out in Pulmonary Artery and Aorta. SA Node is also known as Natural Pacemakers.
Functions of Heart :
It is a pumping organ which pumps blood. It is most vital oragan of body which failure leads to death.
HEART MUSCLES :
Also known as Cardiac muscles. These are specialised tissues which are continuously contracting and relaxing. They are self exitable and involuntary in nature. They are helpful to pumps blood into lungs (through Pulmonary Artery) and complete body (through Aorta).

Structure: Cardiac muscles are highly branched. They have cells that arer connected by overlapping projections called intercalated discs. They contain desmosomes and gap junctions.
Functions:
- Pump blood all over the body
- Carries the weight of the heart
Diseases:
- Coronary artery disease
- High blood pressure
- Stroke
- Congenital heart disease
Preventive measures:
- Keeping cholesterol and triglyceride under control
- Involve in physical exercises
- Healthy lifestyle
- Quit smoking
- Keep A1C in check.
