Do you need a diagram of the heart?

The diagram of heart is beneficial for Class 10 and 12 and is frequently asked in the examinations. A detailed explanation of the heart along with a well-labelled diagram is given for reference. The upper two chambers of the heart are called auricles.

How are the two chambers of the heart separated?

How the Healthy Heart Works. The upper two chambers are the atria, and the lower two are the ventricles (Figure A). The chambers are separated by a wall of tissue called the septum. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.

What makes the heart open and close in one direction?

The valves open and close to let the blood flow in only one direction. Congenital defects may involve a valve, a chamber, the septum, an artery or blood flow issues. The four heart valves are:

How is the output of the heart controlled?

Cardiac output is a measure of the rate of blood flow through the heart and its associated blood vessels. Changes of pressure allow the blood to flow through the cardiac cycle. This is controlled by the cardiac conducting system and regulated by the medulla via the autonomic nervous system.

How are the left and right sides of the heart divided?

It is divided into the left and right side by a muscular wall called the septum. The right and left sides of the heart are further divided into two top chambers called the atria, which receive blood from the veins, and two bottom chambers called ventricles, which pump blood into the arteries.

How does the electrical system of the heart work?

In the simplest terms, the heart is a pump made up of muscle tissue. Like all muscle, the heart needs a source of energy and oxygen to function. The heart’s pumping action is regulated by an electrical conduction system that coordinates the contraction of the various chambers of the heart. How does the heart beat?
