What is the path of blood flow through the heart and lungs?

Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood leaves the heart through the aortic valve, into the aorta and to the body.

How blood flows through the heart step by step?

1 Here are the steps of blood flow through the heart and lungs:

  1. The blood first enters the right atrium.
  2. The blood then flows through the tricuspid valve into the right ventricle.
  3. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.

What is the path that the blood flows through the heart?

Blood flows from the right atrium into the right ventricle through the tricuspid valve. When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium. Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs.

What are the different kinds of the blood vessel?

There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart.

How does blood flow to and from the heart?

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.

How does blood flow through the 4 chambers of the heart?

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.

What are the 4 main blood vessels?

There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins. Arteries carry blood away from the heart to other organs. They can vary in size.

What are the 5 Major blood vessels?

Key points

  • The vasculature works with the heart to supply the body with oxygen and nutrients and to remove waste products.
  • There are five classes of blood vessels: arteries, arterioles, veins, venules and capillaries.
