answers for all of them please (｡･ω･｡)ﾉ♡
Answers
Answer:
Septum:- The septum is used to separate the two chambers of the heart containing two different types of blood, namely oxygen rich blood and deoxygenated blood, such that they can be separately pumped out of the heart.
Valves:- The valves present in the heart prevents the back flow of blood.
VENTRICLE:
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
ATRIA:
There are two atria in the human heart – the left atrium receives blood from the pulmonary (lung) circulation, and the right atrium receives blood from the venae cavae (venous circulation). The atria receive blood while relaxed (diastole), then contract (systole) to move blood to the ventricles.

Answer:
Septum:-
septum forms a barrier between left and the right ventricle. Atrial septum forms a barrier between left and the right atrium. ... Thus, the role of septum is to prevent the mixing of the oxygenated which is oxygen rich and deoxygenated which is oxygen poor blood.
AV valves:-
The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle
Semilunar Valve:-
Therefore, the functions of semilunar valves are to allow the flow of blood in one direction to the major arteries carrying the blood to distant regions of the body and to prevent the backflow of the blood from large vessels such as the aorta and pulmonary artery to ventricles in the heart.
Ventricle:-
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
Atria:-
There are two atria in the human heart – the left atrium receives blood from the pulmonary (lung) circulation, and the right atrium receives blood from the venae cavae (venous circulation). The atria receive blood while relaxed (diastole), then contract (systole) to move blood to the ventricles.
