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 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.
- The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

What is the pathway of blood through the heart quizlet?
Oxygen-poor blood enters heart thru the Inferior Vena Cava or the Superior Vena Cava. It enters the right atrium and flows through the Tricuspid Valve into the right ventricle. The left ventricle pumps the blood through the aortic (semilunar) valve to the Aorta, where the oxygen-rich blood returns to the body.
What are the steps of blood flow?
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.

Where is the vena cava?
The inferior vena cava (IVC) is the largest vein of the human body. It is located at the posterior abdominal wall on the right side of the aorta. The IVC’s function is to carry the venous blood from the lower limbs and abdominopelvic region to the heart.
What are the downstairs chambers called?
The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle.
Which is the correct order of blood flow quizlet?
Terms in this set (11)
Blood enters right atrium from superior and inferior vena cavae. Blood in right atrium flows through right AV valve (tricuspid) into right ventricle. Contraction of right ventricle forces pulmonary semilunar valve open. Blood flows through pulmonary valve into pulmonary trunk.
Is mitral valve bicuspid or tricuspid?
opening is guarded by the mitral, or bicuspid, valve, so named because it consists of two flaps. The mitral valve is attached in the same manner as the tricuspid, but it is stronger and thicker because the left ventricle is by nature a more powerful pump working under high pressure.
How does blood circulation work?
The circulatory system (cardiovascular system) pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over.
How many valves are in a heart?
There are 4 valves in your heart: Aortic valve. Mitral valve. Tricuspid valve.
What is the most important valve in the heart?
The aortic valve is the final valve that oxygen-rich blood passes through before exiting the heart and coursing through the rest of the body. The valve prevents blood from flowing back to the left ventricle.
What is the largest valve in the heart?
The aortic valve opens the way for oxygen-rich blood to pass from the left ventricle into the aorta, your body’s largest artery.
What is the part of heart?
Your heart is divided into four chambers. You have two chambers on the top (atrium, plural atria) and two on the bottom (ventricles), one on each side of the heart. Right atrium: Two large veins deliver oxygen-poor blood to your right atrium. The superior vena cava carries blood from your upper body.
In what order does the blood flow through the heart and lungs?
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 of the heart?
Right ventricle → right atrium → left ventricle → left atrium.
Who described the circulation of blood to and from the heart?
William Harvey and the Discovery of the Circulation of the Blood.
What are the four chambers of the heart?
Each side has a small collecting chamber called an ‘atrium’, which leads into a large pumping chamber called a ‘ventricle’. There are four chambers: the left atrium and right atrium (upper chambers), and the left ventricle and right ventricle (lower chambers).
What is the main artery in the body?
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
What is the largest vein in the heart?
The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium). The superior vena cava carries blood from the brain and arms into the top of the right atrium.
What do veins do?
The veins (blue) take oxygen-poor blood back to the heart. … They carry oxygen-rich blood away from the heart to all of the body’s tissues. They branch several times, becoming smaller and smaller as they carry blood further from the heart.
What is the largest vein in the human body?
The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
What divided the heart into two?
A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart.
What part acts like doors that control blood flow in the heart?
Heart valves (the doors between the rooms)
There are four heart valves, which act like doors between the chambers of the heart. They open and close as your heart pumps. The valves only open one way. This stops blood flowing in the wrong direction between the chambers of your heart.
What separate the heart into two sides?
The right and left sides of the heart are separated by a muscular wall that prevents blood without oxygen from mixing with blood that has oxygen. The heart also has valves that separate the chambers and connect to major blood vessels.
Does blood flow from high to low pressure?
Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins. The rate, or velocity, of blood flow varies inversely with the total cross-sectional area of the blood vessels.
Which answer gives the correct blood flow in order?
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.
Which heart valves are bicuspid?
A bicuspid aortic valve is an aortic valve that has two flaps (cusps) instead of three. It may cause a narrowed or obstructed aortic valve opening (aortic valve stenosis), making it difficult for the heart to pump blood into the body’s main artery (aorta).
What is another name for the bicuspid valve?
A bicuspid aortic valve is an aortic valve that has two flaps (cusps) instead of three. It may cause a narrowed or obstructed aortic valve opening (aortic valve stenosis), making it difficult for the heart to pump blood into the body’s main artery (aorta).
What is the difference between bicuspid and tricuspid valve?
The bicuspid aortic valve is an aortic valve with two cusps found between the left atrium and left ventricle. The tricuspid aortic valve is an aortic valve with three cusps found between the right atrium and right ventricle.
What are the 3 types of circulation?
3 Kinds of Circulation:
- Systemic circulation.
- Coronary circulation.
- Pulmonary circulation.
How does blood get back to the heart?
Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart. … From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.
