Question

Distinguish between right atrium and left atrium

Answer 1

Heya!

Here is yr answer.......


LEFT ATRIUM :
---------------------

➡️ Located at the left side of heart
➡️ recieves oxygenated blood
➡️ Blood is recieved from pulmonary vein
➡️ it allows blood into left ventricle

RIGHT ATRIUM:
----------------------

➡️ Located at the right side of heart
➡️ recieves de-oxygenated blood
➡️ blood is recieved from superior and inferior vena cava.
➡️ it allows blood into right ventricle.



Hope it helps.....

hello friend...

Here is your answer -
***************************************************
First of all let's talk about some simple structure of Human Heart.

HUMAN HEART

It is located in the mid thoracic region inside a depression called as Cardiac Knotch. It shows a cleft fist shape slightly tilted towards left.
Human heart is also known as Pumping organ of the body as it pumps blood to the body. It is also known as Myogenic because it is auto-exitable in nature.
Human heart has four chambers - 2 atrium and 2 ventricles. Upper chambers are receiving chambers as they receives blood from body (right atrium) and from lungs (left atrium) while lower chambers are distributing chambers because they distributes blood to lungs (right ventricle) and to the entire body (left ventricle).

ATRIUM
( Differences between both atrium ).

Right Atrium - Right atrium recieves blood from different parts of the body through vena cava [ Inferior vena cava (from lower side of body) and Superior vena cava (from upper part of the body)]. It also receives blood from heart itself through coronary sinus. After receiving blood it transfers them into the right ventricle through tricuspid valve. It always carries deoxygenated blood.

Left Atrium - Left Atrium receives blood from lungs only through pulmonary veins. These blood are oxygenated blood. They get transferred into right ventricle through Mitral Valve or Semilunar valve.

VENTRICLES -

Right Ventricle - It recieves blood from right atrium and pumps into pulmonary artery. It is the biggest chamber of heart.

Left Ventricle - It receives blood from left atrium and pumps into aorta. Through aorta blood gets distributed into whole body and heart muscles itself.

Both Ventricles are seperated by interventricular septum.
