Are the circulatory system and the cardiovascular system the same?
No they are not the same. The cardiovascular system involves the circulatory system and the lungs and it transports oxygen and removes co2 from the body. On the other hand the circulatory system is responsible for moving blood throughout the body. So while they involve the same parts they are not the same system
How does the heart work with other organs in the circulatory system?
There are many ways the heart works with other organs. Heart pumps blood throughout the body, to other organs, which brings them oxygen. Without a fresh supply of oxygenated blood the other organs will die. The heart works with the lungs via the pulmonary circulatory system in order to oxygenate the blood. Deoxygenated blood, high in carbon dioxide waste, is pumped from the right ventricle through the pulmonary artery to the lungs to pick up oxygen and loose carbon dioxide. The blood then returns into the left atrium via the pulmonary vein before being pumped to all other parts of the body.
The digestive system delivers nutrients to your blood, which the circulatory system carries to tissues. But remember, without your nervous system, your body wouldn't be able to function.
The heart pumps hormones from the endocrine system throughout the body, allowing them to reach their target receptors to keep the body in balance.
There are many things you can do to maintain a good circulatory system. Some good habits include:
���have a regular exercise.
���eat balanced diet.
���avoid smoking and alcoholic drinks.
���avoid extreme emotions like anger, excitement, etc.
���avoid fatty foods.
���eat fruits and vegetables.
���avoid eating junk foods.
What kind of wound spurts bright red blood?
This would be arterial bleeding - bright red pertains to oxygen-rich blood and the squirting is because of the pressure from the heart. Venous blood will appear dark, and oxygenated blood from the arteries will appear bright red in color.
Is the heart one of the hardest working organs in your body?
I think so. It is constantly pulsating blood and nutrients throughout our body. It doesn't have time to just stop and sleep! I'm studying the circulatory system, and I got this information out of a textbook...
The first set of blood that comes in to the first half of the heart (the right half) is blood coming from the rest of the body (such as muscles, brain, other organs etc.) This set of blood does NOT have oxygen as the body has already used it up. Such blood is said to be deoxygenated.
Now, you don't want to pump this blood back round again because it does not have any oxygen in it so you want it to go to the LUNGS where it can become reinfused with oxygen.
So the right half of the heart will pump that first set of blood to the lungs and then it will return to the second part of the heart (the left half) as oxygenated blood. You don't want it returning to the first half because then it will get mixed with the deoxygenated blood.
Now this second half of the heart will pump the oxygenated blood to the rest of the body to meet the body's demand for oxygen. So one of the reasons it's in 2 halves is to separate the oxygenated blood from the deoxygenated blood so that the two types of blood don't mix.
Now, you might be asking the question. Well, why doesn't the heart just pump the blood to the lungs AND to the body ALL IN ONE GO.
Problem is pressure.
The lungs are relatively weak structures. If you wanted your heart to pump in one go so that all the blood reaches the lungs AND then reaches all parts of your body AND return back to the heart, that would require a LOT of force. That amount of force will rupture your lungs.
So what happens is that the blood that is pumped from the first half to the lungs, is pumped with a much lower force than the blood that is pumped from the second half. That protects your lungs from becoming damaged.

New Answer "
As Said in the previous answer Which states that the deoxygenated blood moves into the right half of the heart whereas the oxygenated blood moves into the left half . now i will answer what happens if it the de oxygenated blood mixes with the oxygenated blood . The amount of energy released will be really less as there wont be much O2 , if only de oxygenated blood moves continously in our body no enery will be released thats why the lungs are present where the conversion of De Oxygenated blood gets converted into pure / oxygenated blood so i can produce energy and yes if both mix up the impurities will also lead to some problem . like urin when collected in the urinary bladder gets acidic when more and more impurities get collected , almost the same thing happens here also .
How does the lymphatic system function with the digestive system?
It is easiest to think of the lymphatic system as being, in many ways, analogous to the circulatory system. Both are extensive networks of tubes that go virtually everywhere in the body. But where the circulatory system moves blood around the body, the lymphatic system moves a clear liquid known as lymphthroughout the body.
Five diseases of the circulatory system?
Diseases of the circulatory system affect the heart, veins, arteries, and capillaries. Five diseases of this system are atherosclerosis, deep vein thrombosis, hypertension, varicose veins, and angina.
Is the circulatory open or closed?
The circulatory system can be open or closed, it depends on your species/ organism
What other body systems work with the digestive body system?
The circulatory system is connected to the digestive system. The circulatory system is important to the digestive system so that digestion can take place and so that nutrients can be released into the bloodstream.
Why do mammals have a double circulatory system?
The heart is basically two pumps. The right side of the heart pumps deoxygenated blood from the body to the lungs, where it is oxygenated. This is known as the pulmonary circulation. The left side of the heart receives this newly oxygenated blood from the lungs and pumps it around the rest of the body. This is known as the systemic circulation. There are therefore two different circulations, which although they work with eachother, are seperate.
Why do larger organisms need a circulatory system?
The circulatory system is necessary in a complex multicellular organism like a human because oxygen must be circulated throughout the body to feed the organs and tissues. The blood also removes waste from the organs and tissues (the exchange of gases takes place during circulation). Tiny vessels must pass near every cell in the body and there are a trillion of them.
How do single circulatory system work?
when the blood follows one circuit pathway through the body , it is
termed as single circuit plan

What does the respiratory system allow us to do?
When we breathe from our mouth or nose, the air, which contains oxygen, nitrogen, and other types of gases, pass the larynx, where the vocal cords locate. When oxygen reaches the chest cavity, the bronchi divides itself so that the bronchi can direct the oxygen to the lungs. When the bronchial tubes direct the oxygen and air into the alveoli, it then reaches your bloodstream. When the respiratory system finishes its course, the diaphragm, which locates under the chest cavity, eliminates carbon dioxide. This explains why we have to exhale after we inhale.
The main purpose of the respiratory system is to supply oxygen for the blood and other organs such as the brain.
What is the path that blood follows through the body beginning at the heart?
The path of blood from the heart to the kidneys is first from the abdominal aorta the blood enters the kidney through the renal artery. Then the renal artery divides into a number of segmental arteries. The segments arteries divide into lobar artery. The lobar arteries divide into inter-lobar arteries that travel between the renal pyramids. The inter-lobar arteries branch into arcuate arteries that travel between the cortex and medulla. From the arcuate arteries the blood is carried into the nephrons. In the nephron the blood enters through the afferent arteriole and into the glomerulus. The blood leaves the glomerulus by the way of the efferent arteriole, which the blood is carried to the peritubular capillaries, and finally to the vasa recta. When the blood reached the vasa recta that means that it had travelled through the whole nephron.
The blood travels back to the heart through the veins. First through the interlobular vain, then through the arcuate vein, then through the interlobar vain, then through the segmental vain, and finally exists the kidney by the way of renal vein, and into the inferior vena cava.
How many valves are in the blood circulatory?
There are four valves of the heart: two are located between the atria and ventricles of the heart (called atrioventricular valves) and two are located in the major vessels leaving the valves (called semilunar valves). The left atrioventricular valve is also known as the bicuspid valve or the mitral valve. The right atrioventricular valve is also known as the tricuspid valve. The two semilunar valves are named after the vessel they lie within: the left semilunar valve is called the aortic valve because it lies within the aorta; the right semilunar valve is called the pulmonic valve because it lies within the pulmonary artery.
Ruben Joubert
There are four valves in the human heart. There is the aortic vavle, the tricuspid valve, the pulmonary valve and the mitral valve.
The are two types of four main valves. The first two are the atrioventricular valves. These valves separate the atria from the ventricles. The two atrioventricular valves are the mitril valve and the tricuspid valve. The other type of valve are the semilunar valves. The semilunar valves are between the ventricles (which pump blood) and the arteries that flow away from the heart. The two semilunar valves are the aortic and pulmonary valves.
There are four one-way valves in a human heart. These are the only valves in the heart.
There are four valves in the heart (not counting the valve of the coronary, the isotonic valve and the valve of the inferior vena cava): two atrioventricular valves (mitral valve and tricuspid valve); and two semilunar valves (aortic valve and pulmonic valve).
How do the kidneys help the circulatory system?
The circulatory system helps by pumping oxygen rich blood to the rest of the body (from the heart), being a source of travel for the blood so it can reach all parts of the body (blood vessels), removing carbon dioxide and other wastes from the cells in the body via the blood, and providing the various cells in the body with oxygen so that they can carry out various cell processes, such as cellular respiration, which keep a living organism alive. Without oxygen, and a means to be rid of carbon dioxide and wastes, humans and other organisms would not be able to survive.
How does the circulatory system bring oxygen to ever cell in body?
The circulatory system play a key role in providing the body with the oxygen needed by cells. The circulating blood carries the oxygen replenished red cells through the arteries to all parts of the body.
What is a layer of the heart largely composed of cardiac muscle tissue?
This word can be broken down into two parts that will reveal the answer to your question. Myo is the medical term for muscle and cardio is the medical term for heart. Therefore, your answer would be the muscle that is the heart.
How does the respiratory system and circulatory system connect?
In the lungs,Blood is exchanged adn sent to different parts of the body.
Can too much oxygen be deadly for the human body?
- Yup. Here are some of the problems that can happen:
- Pulmonary edema (intensive-care patients on breathing machines at 30 hours or more exposure)
- Decreases in the rate of gas exchange across the alveoli (intensive-care patients on breathing machines at 30 hours of exposure)
- Chest pains that were worse during deep breathing (volunteers with 24 hours of exposure)
- Decrease in the total volume of exchangeable air in the lung (vital capacity) by 17 percent (volunteers with 24 hours of exposure)
- Local areas of collapsed alveoli when plugged by mucus, a condition called atelectasis (patients, volunteers). The oxygen entrapped in the plugged alveolus gets absorbed into the blood, no gas is left to keep the plugged alveolus inflated and it collapses. Mucus plugs happen normally but are cleared by coughing. Also, if alveoli become plugged during air breathing, the nitrogen entrapped in the alveoli keeps them inflated.
- blindness caused by inadequate development of the capillaries in the lens and retina of the eye (premature infants). Reducing the oxygen to 40 percent can prevent this blindness.
What is an open circulatory system?
A Closed Circulatory system-Is a blood circulation system in which blood moves through the body in closed vessels.
In the closed circulatory system, the blood is confined to vessels. The heart pumps blood to vessels through smaller vessels which go to the organs. This system has a more efficient way of transporting blood then an open circulatory system.
Some animals that have this systems include earthworms, squids, octopus, and all vertebrates, like humans.
How is the respiratory system affected by pollution?
smoking: lung cancer, caused you to cough grossly and choke
smog: it will make you sick and it could give you cancer
pollen: allergies, sneezing, coughing, ichy eyes and nose, runny nose
What system returns fluids to circulatory system?
The cardiovascular system transports liquid and nutrients throughout the body.
