Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the
capillaries
in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.
How does blood flow through the circulatory system step by step?
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.
What are the 7 steps of blood flow?
Blood flows through the heart in the following order: 1) body –> 2) inferior/superior vena cava –> 3) right atrium –> 4) tricuspid valve –> 5) right ventricle –> 6)
pulmonary arteries
–> 7) lungs –> 8) pulmonary veins –> 9) left atrium –> 10) mitral or bicuspid valve –> 11) left ventricle –> 12) aortic valve –> 13) …
How does blood flow through the heart step by step quizlet?

The blood
flows through the tricuspid valve into the right ventricle
. The right ventricle contracts and blood flows from the pulmonary artery to the lungs. The deoxygenated blood picks up oxygen. Oxygenated blood flows along the pulmonary veins into the left atrium.
What are the 16 steps of blood flow through the heart?
- #1. inferior vena cava.
- #2. superior vena cava.
- #3. right atrium deoxygenated.
- #4. tricuspid valve.
- #5. right ventricle.
- #6. pulmonary semilunar valve.
- #7. pulmonary artery.
- #8. lungs to get oxygen.
How does blood enter the heart steps?
Blood enters the heart through two large veins,
the inferior and superior vena cava
, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.
What order does the blood flow through the heart valves?
Blood flows from the right atrium into the right ventricle through the
open tricuspid valve
, and from the left atrium into the left ventricle through the open mitral valve.
Which sequence is the correct pathway for blood flow through the heart?
Which sequence is the correct pathway for blood flow through the heart? Explanation: The correct pathway for blood flow through the heart is the
right atrium – tricuspid valve – right ventricle – pulmonary artery – lungs – pulmonary vein – left atrium – mitral valve – left ventricle – aorta
. You just studied 36 terms!
What is the order of blood flow through the heart assume we are starting at the superior and inferior 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.
In what order does blood flow through the body and heart gizmo?
In what order does blood flow through the body and heart?
Rt atrium, Lt atrium, lungs, Rt vent, Lt vent, body
.
How does blood travel to different parts of body?
Two types of blood vessels carry blood throughout our bodies:
Arteries carry
oxygenated blood (blood that has gotten oxygen from the lungs) from the heart to the rest of the body. Blood then travels through veins back to the heart and lungs, so it can get more oxygen to send back to the body via the arteries.
Which type of blood vessel usually carries oxygen-poor blood gizmo?
The pulmonary artery
carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.
In what order does blood flow through the body and heart quizlet?

Unoxygenated blood blood enters the right atrium from the superior and inferior vanae cavae. The blood flows through the
tricuspid valve
into the right ventricle. From the right ventricle, the blood flows through the pulmonic valve into the pulmonary artery.
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.
In what type of circulation does the blood flow between the heart and lungs?
Pulmonary circulation
moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
Where is urea enter the blood?
Ammonia is a toxic product of nitrogen metabolism which should be removed from our body. The urea cycle or ornithine cycle converts excess ammonia into urea in the
mitochondria of liver cells
. The urea forms, then enters the blood stream, is filtered by the kidneys and is ultimately excreted in the urine.
What is the largest artery in the body?
Aorta
Anatomy
The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.
How does blood volume affect blood flow?
Similarly, as blood volume decreases, pressure and flow decrease. As blood volume increases,
pressure and flow increase
. Under normal circumstances, blood volume varies little.
Do veins carry blood to the heart?
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and
veins carry blood back to the heart
.
How do arteries regulate blood flow?
Large arteries receive the highest pressure of blood flow and are more thick and elastic to accommodate the high pressures. Smaller arteries, such as arterioles, have more smooth muscle which contracts or
relaxes
to regulate blood flow to specific portions of the body.
How does blood move forward through the veins?
Blood primarily moves in the veins by
the rhythmic movement of smooth muscle in the vessel wall and by the action of the skeletal muscle as the body moves
. Because most veins must move blood against the pull of gravity, blood is prevented from flowing backward in the veins by one-way valves.
