Definitively yes. Each chamber contracts following the cell membranes depolarization of its corresponding cells, which are in turn depolarized by the segment of the conducting system of the heart in contact with them. The heart chambers do not communicate among them electrically, they are separated by insulating dense connective tissue. The current responsible for depolarizing cell membranes of the heart only travels by using the route of the conducting system of the heart.

SA node, AV node, AV bundle (Bundle of His), Purkinje fibers.

What else can I help you with?
What type of blood in each chamber of the heart?
The bloody kind
Why cant the heart have only two chambers either than four?
Because each chamber has its own function, the blood goes somewhere else from each chamber.
Does the rack come with the dumbbells and kettlebells or are they purchased seperately?
Yes all the components are sold seperately and the kettlebells are sold by the weight of each.
How many times does your heart contract each minute under normal conditions?
pickles
Between the chambers of the heart are?
Between each chamber of the heart, there is one of two things, depending on the relationship of the chambers. If blood flows from one chamber to the other, there is a 1-way valve preventing backup. If blood never goes from one chamber to another, ie, the left ventricle and the right ventricle, then there is a layer of tissue blocking passage of blood from one chamber to the other.
Why human heart is made up of four chamber?
so that the oxygenated and unoxygenated blood did not mixed with each other
Where is the atria found?
The atria are found in the heart, specifically in the upper chambers. There are two atria in the heart, the left atrium and the right atrium, which receive blood from the veins and pump it into the ventricles.
How do you write about the family background?

How many compartments does the heart have?
The heart is divided into 4 chambers: 2 on the right hand side and 2 on the left. Each upper chamber is known as an atrium and each lower chamber as a ventricle. The 4 compartments are known as: the right atrium; the right ventricle; the left atrium and the left ventricle.
How many atria and ventricles do you find in a fish heart?
2, the atria is the upper chamber of the heart. since there is alower and upper chamber in the heart, and the upper part is the atria, do the math: four chamber divided in half (two lower and two upper and 2+2=4) equals two which gives the the number of atria!
What is the purpose of intercalated discs in cardiac muscle tissue?
An intercalated disc forms connections between neighboring cells in the heart. Two types of connections are formed at each intercalated disc, which connects the cell membranes of two myocytes (heart muclse cells). One is a physical connect and the other is a chemical link. These allow the heart to beat as if it is almost one cell. Other factors slow the coordination so that the heart muscle will contract top to bottom.
