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.
How does the blood flow through the heart step by step?
Blood Flow Step by Step
- The blood first enters the right atrium.
- The blood then flows through the tricuspid valve into the right ventricle.
- When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
What is the flow of blood through the heart in order?
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. This pattern is repeated, causing blood to flow continuously to the heart, lungs and body.
What is the correct sequence for the path of blood through the body?
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 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.
Where does the blood bring oxygen to?
Blood with fresh oxygen is carried from your lungs to the left side of your heart, which pumps blood around your body through the arteries. Blood without oxygen returns through the veins, to the right side of your heart.
What chamber does blood come from to enter the aorta?
The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
Which blood vessels carry blood to the heart?
Veins. Veins carry blood toward the heart. After blood passes through the capillaries, it enters the smallest veins, called venules. From the venules, it flows into progressively larger and larger veins until it reaches the heart.
What is the path of a drop of blood?
Explanation: The correct path of a drop of blood through the vascular system is right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arteriorles, capillaries, venules, veins, vena cavae.
What are the 5 Major blood vessels?
There are five classes of blood vessels: arteries and arterioles (the arterial system), veins and venules (the venous system), and capillaries (the smallest bloods vessels, linking arterioles and venules through networks within organs and tissues) (Fig 1).
What is the largest artery in the body?
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
What is the main blood vessel?
Throughout the body, the arteries (in red) deliver oxygenated blood and nutrients to all of the body’s tissues, and the veins (in blue) return oxygen-poor blood back to the heart. The aorta is the large artery leaving the heart.
