What Does The Circulatory System Do
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.
The circulatory system carries oxygen, nutrients, and to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.
Blood Flow To The Heart
After the blood has passed through the capillary beds, it enters the venules, veins, and finally the two main venae cavae that take blood back to the heart. The flow rate increases again, but is still much slower than the initial rate in the aorta. 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. Thus, because skeletal muscle contraction aids in venous blood flow, it is important to get up and move frequently after long periods of sitting so that blood will not pool in the extremities.

Where Does The Left Ventricle Pump Blood To
The left ventricle then pumps blood through the aortic valve and into the aorta, the blood vessel that leads to the rest of the body. Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen is used.

Which Is The Correct Direction Of Blood Flow
The correct direction of blood flow is: right atrium > right ventricle > pulmonary artery.
What is the correct or Order 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) aorta -> 14) body.
What is the Order of the blood circulatory system?
So blood moves: heart artery arteriole capillary venule vein heart . This is called circulation. There are two different circulations in the circulatory system. The systemic circulation is how blood goes to most of the body. The pulmonary circulation is how blood goes through the lungs.
What are the steps of blood flow?
Here are the steps for blood flow to the heart: to the superior and inferior vena cava,then to the right atrium.through the tricuspid valve.to the right ventricle.through the pulmonic valve.to the pulmonary artery.to the lungs.
There Are Two Types Of Circulation: Pulmonary Circulation And Systemic Circulation
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. It sends oxygenated blood out to cells and returns deoxygenated blood to the heart.

Where does blood flow through the four chambers?
Starting at the right atrium in what order does blood flow through the four chambers? From right atrium to right ventricle, which pumps the blood to the pulmonary arteries and through the lungs where blood dumps CO2 and picks up O2.
What Are The Parts Of The Heart
The heart has four chambers two on top and two on bottom:
- The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart. A wall called the interventricular septum is between the two ventricles.
- The two top chambers are the right atrium and the left atrium. They receive the blood entering the heart. A wall called the interatrial septum is between the atria.
The atria are separated from the ventricles by the atrioventricular valves:
- The tricuspid valve separates the right atrium from the right ventricle.
- The mitral valve separates the left atrium from the left ventricle.
Two valves also separate the ventricles from the large blood vessels that carry blood leaving the heart:
- The pulmonic valve is between the right ventricle and the pulmonary artery, which carries blood to the lungs.
- The aortic valve is between the left ventricle and the aorta, which carries blood to the body.

What Is The Order Of Blood Flow Through The Nephron
Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.
What Signals Control Your Heartbeat
Your heart contracts when it receives an electrical impulse from your sinoatrial node. This signal is called heart conduction. The SA node is your bodys natural pacemaker, setting your hearts rhythm.
Heart conduction continues as the electrical signal moves to the atrioventricular node in your right atria. The signal then travels down the His-Purkinje system and spreads to the rest of your heart.
How fast or slow your heart beats varies throughout the day. Your nervous system sends electrical signals and your endocrine system sends hormones that control your heart rate. These signals help your heart adapt to your bodys changing needs. For example, your heartbeat quickens when you run and slows when you sleep.

What Is The First Step Of The Blood Flow Path
Blood Flow Step by Step 1 Here are the steps of blood flow through the heart and lungs: 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.
Blood Flow Away From The Heart
With each rhythmic pump of the heart, blood is pushed under high pressure and velocity away from the heart, initially along the main artery, the aorta. In the aorta, the blood travels at 30 cm/sec. From the aorta, blood flows into the arteries and arterioles and, ultimately, to the capillary beds. As it reaches the capillary beds, the rate of flow is dramatically slower than the rate of flow in the aorta. While the diameter of each individual arteriole and capillary is far narrower than the diameter of the aorta, the rate is actually slower due to the overall diameter of all the combined capillaries being far greater than the diameter of the individual aorta.

Supplying Oxygen To The Hearts Muscle
Like other muscles in the body, your heart needs blood to get oxygen and nutrients. Your coronary arteries supply blood to your heart. These arteries branch off from the aorta so that oxygen-rich blood is delivered to your heart as well as the rest of your body.
- The left coronary artery delivers blood to the left side of your heart, including your left atrium and ventricle and the septum between the ventricles.
- The circumflex artery branches off from the left coronary artery to supply blood to part of the left ventricle.
- The left anterior descending artery also branches from the left coronary artery and provides blood to parts of both the right and left ventricles.
- The right coronary artery provides blood to the right atrium and parts of both ventricles.
- The marginal arteries branch from the right coronary artery and provide blood to the surface of the right atrium.
- The posterior descending artery also branches from the right coronary artery and provides blood to the bottom of both ventricles.

Where Does Blood Flow In And Out Of The Heart
This video describes how blood flows in and out of the heart. the posterior and the anterior 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.
Where does the superior vena cava come from?
Superior Vena Cava & Inferior Vena Cava The vena cava is the largest vein in the body that delivers oxygen-poor or deoxygenated blood to the right atrium of the heart. The superior vena cava comes from the upper part of the body, including the brain and arms, while the inferior vena cava comes from the abdominal area and legs.
Where does blood go after it leaves the pulmonary veins?
From the pulmonary veins, blood flows into the left atrium. 7. From the left atrium, blood flows through the bicuspid valve into the left ventricle. 8. From the left ventricle, it goes through the aortic semilunar valves into the ascending aorta.
How Does Blood Flow Through The Heart
The right and left sides of the heart work together. The pattern described below is repeated over and over, causing blood to flow continuously to the heart, lungs, and body.
Right side
- 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.
- As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
- When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.
- As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
Left side
- The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium.
- As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.
- When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
- As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.
