★ Facts:-
----> Heart can perform its function outside the body.
----> Heart can generate its own electric impulse.
----> While you go about your daily activities, your heart is a working tirelessly to pump blood through a network of vessels that, if you laid out, could circle the earth almost two and half times. yes, you read that right, your heart is the powerhouse behind this incredible journey of approximately 60,000 miles every single day.
★ What is Heart?
----> The heart is a muscular organ that plays a vital role in the circulatory system, responsible for pumping blood throughout the body. It is situated in the chest cavity, slightly to the left of the midline, and is protected by the ribcage. The human heart is a complex and essential organ composed of various components, each contributing to its overall function.
---->It is playing most important role in an every living being or thing in the world. where it keep the organism live with the blood flow due to circulation. As the heart is all the Cardiovascular tissue made it all the organ plant.
• About Cardiovascular Tissue:
----> Cardiovascular tissue refers to the specialized type of tissue that makes up the heart and blood vessels in the circulatory system. The Cardiovascular System, composed of the heart and blood vessels, is responsible for the circulation of blood thought the body, delivering oxygen, nutrients, and hormone to cell and removing waste products.
-----> Here are some main components of Cardiovascular tissue
• Cardiac Muscle Tissue
• Endothelial Tissue
• Connective Tissue
• Blood.
----> As same the heart is all about circulatory system.
★ Anatomy of the Heart
--->Now , we need to get an inside Knowledge of an system of an heart.
★ Working | Function | Circulation of the Heart
-----> As we know that Heart also known as Cardiovascular Tissue building muscles also a cardio muscles developed organ which is a life of an human lives or living organism which is been help for blood circulation and it follows the circulatory system process.
-----> The Heart divided into four chambers by following:
• Left Atrium • Right Atrium
• Left Ventricle • Right Ventricle
• Left Side of Heart:-
--->The Left Side of the Heart is that said that it help to flow the Oxygenated blood to the body. In more detail specifically the oxygenated blood come to the Left Atrium from the two Pulmonary Vein which are connected to the Lung and then the Left Atrium get compress and the flow of oxygenated blood goes to the Left Ventricle through passing the value named Bicuspid Valve also called Mitral. Then the Left Ventricle compress and Left Atrium relax at that time the oxygenated blood do not backtracking due to the Bicuspid Valve is attached to the Tendents Chord which are rooted to the specialize muscle called Papilary Muscles. This are help to open and close of the AtrioVentricular Valve or Muscles. At the contraption the blood in the Left Ventricle get passed to the Arota and whole part of the body through the "Semilunar Valve" named as Arotic Seminular Valve.
• Right Side of Heart:-
---->The Right Side of the Heart is performing same activity as the left part but it help to flow the Deoxygenated Blood from the body to lungs. it flow as the Deoxygenated blood drained from the upper and lower part of the body. Means the Deoxygenated blood goes to the Right Atrium Through two veins called as Vena-Cava. There are two parts of vena cava namely-
• Superior Vena-Cava --(Top)
• Inferior Vena-Cava --(Bottom)
After the Deoxygenated blood flows to the Right Atrium The right part compress then blood flow to the Right Ventricle through Tricuspid Valve and the support to the AtrioVentricular muscles is given by the Tendents cord which is rooted with Papilary Muscles. In the next step the Right Ventricle compress and Right Atrium get relax at that time the blood go to the lungs Through the opening of the Arteries names Pulmonary Arteries or Pulmonary Arteries Semilunar Valve.
---->Note:- The Noice made by heart is "LUB-DUB" due to -
Lub - Atrioventricular Valve
Dub - Semilunar Valve
★ Heart Jargon
1) Chambers :- • Left Atrium • Right Atrium
• Left Ventricle • Right Ventricle
2) Veins :- Passing towards the Heart.
• Pulmonary Veins ---(Left Side of the Heart)
• Vena Cava ---(Right Side of the Heart)
3) Artery :- Passing outside of the Heart.
• Arota
4) Arota :- The Arota is the Artery which flow the Oxygenated blood through all part of the body.
5) AtrioVentricular muscles :- The Border between Artium and Ventricle on both side.
6) Valves :- Opening and Closing of the passage
• Bicuspid Valve
• Tricuspid Valve
• Semilunar Valve
7) Septum / Cardiac Septum :- Seperation Between Left Side and Right Side of the Heart also called Interatrioventricular Septum.
8) Preicardium :- The outer layer protecting the inner layer.
9) Endocardium :- The inner layer to make a smooth blood flow.
10) Mayocardium :- The Muscle part of the heart by which the heart is been rounded.
★ The Electric Impulse System in Heart
----> The Electric Contraption is inside the heart. There is a specialized electric active Myocardiac tissue which deals to supply of an electric impulse to heart. where it is called Syno Atrium Node of heart. It is Electrically Intrinsically unstable which is placed or held on Right side of the heart at Right Atrium near to the Vena - Cava.
----> It is Depolarize Spontaneously 90 to 100 times therefore generating new electric impluse activity/ signal there are another electrical activity in heart that is in the ArtioVentricle Septum Node.
-----> These electric impulse is all doing the compressing and relaxing of a myocardiac muscle to keep the heart working.
