What do the red arrows on the diagram of the heart indicate?

The Interior of the Heart The red arrow shows the direction in which oxygen-rich blood flows from the lungs to the rest of the body.

Which part of heart is shown by arrow?

In the given diagram, arrow is shown from atria to the ventricles. It indicates that tricuspid and bicuspid valves are open and the blood is flowing from the atria to the ventricles. During this, the pressure in the ventricles falls and hence they are in the diastolic phase.

What is the pattern of heart?

The heart is divided into four chambers. The upper two chambers are called atria and the lower two chambers are called ventricles. The chambers are separated by a muscular wall that prevents the mixing of the blood rich in oxygen with the blood rich in carbon dioxide.

What is the correct pathway for the flow of blood through the heart starting at the vena cava?

The blood enters the heart from the body through the superior vena cava and the inferior vena cava. Then the blood enters the right atrium chamber of the heart. The blood then moves through the tricuspid valve (shown as two white flaps) into the right ventricle chamber of the heart.

What is the correct order of the path of blood through the heart coming from the body?

The blood enters the left atrium. It drops through the mitral valve into the left ventricle. The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.

What is the path of the vena cava?

Blood enters the heart through two large veins – the posterior (inferior) and the anterior (superior) vena cava – carrying deoxygenated blood from the body into the right atrium. Blood flows from the right atrium into the right ventricle through the tricuspid valve.

What is the path of blood?

Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.

Why are there 4 boxes in a heart diagram?

The boxes are numbered to correlate with the labeled chambers on the cartoon diagram. Image: Diagram of the heart showing the 4 chambers. We will be using the 4 boxes to represent the chambers of the heart.

How to understand the pathway of blood through the heart?

The heart blood flow diagram (flowchart) given below will help you to understand the pathway of blood through the heart.Initial five points denotes impure or deoxygenated blood and the last five points denotes pure or oxygenated blood.

What is the structure of the heart?

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. The lower two chambers of the heart are called ventricles. The outer layer of the heart wall is called epicardium.

What is box 1 and Box 2 in the heart?

Box 1: The first box is located in the right upper region. We know the atria are on top, and since box 1 is located on the right side, this is the right atrium. Box 2: The second box is also located on the right side, but now we are in the lower region.
