What are the mitral and tricuspid valves?
The heart has four chambers. Deoxygenated blood enters the right atrium from around the body via the superior and inferior vena cavae, and travels down through the tricuspid valve into the right ventricle.
The right ventricle pumps the deoxygenated blood to the lungs to be oxygenated, via the pulmonary artery (the only artery that carries deoxygenated blood). It returns via the pulmonary vein (the only vein that carries oxygenated blood) into the left atrium.
Oxygenated blood then enters the left ventricle (the heart's principle pumping chamber, and has particularly thick muscular walls) from the left atrium through the mitral valve. The left ventricle pumps the oxygenated blood at sufficient pressure to travel round the entire body, through the aortic valve and into the aorta.
- Qu.mstr.
No your blood is not red until it hits oxygen, that is why your veins are not red.
The above answer is incorrect. All blood is red but blood with oxygen is brighter red and blood lower in oxygen is darker red. All veins do not carry blood low in oxygen. Most do but not ones coming to the heart from the lungs.
What does the circulatory system look like?
An abnormal heart murmur may have an enlarged heart compared to one without
Which blood vessel carry blood from all over the body back to the heart?
Arteries, the largest of which is the Aorta. Arteries then split down into smaller blood vessels called arterioles and then smaller still into one-cell-thick vessels known as capillaries. These capillaries are where diffusion, movement of Oxygen from the blood vessels into the nearby tissue cells, occurs.
How do you keep circulatory system healthy?
It is important to keep your circulatory system working at its best. Your heart pumps blood to every part of your body. It travels through thousands of miles of blood vessels! Blood carries oxygen from your lungs. If there is a problem with your blood, your heart, or your blood vessels, your whole body can suffer. If you don't get enough oxygen to your brain, you might not be able to think clearly. If your stomach isn't getting enough oxygen, it might be hard for you to digest your food. If there is a problem with one of your blood vessels, blood could stop flowing to a part of your body. Without it, those cells could die.
2 What can you do to keep your circulatory system healthy? You can make sure that you are getting plenty of exercise. When you exercise, you heart beats faster. This makes your heart stronger. Your heart is a muscle. Just like the muscles in your arms and legs, your heart gets bigger and stronger the more that you use it. Exercise also helps to keep your blood vessels working properly. Go outside and play! Ride your bicycle. Go for a swim. Your body will thank you!
3 Eat healthy foods. They will keep your circulatory system healthy. Iron-rich foods like beans, whole-grain breads and cereals, red meat, and green vegetables are good for your blood. Try to avoid fatty foods, especially fried foods and foods that contain a type of fat called trans fat. Eating too much fat can cause fat
What does the Coronary Circulatory System do?
The cardiovascular system consists of the heart, blood vessels and blood. Its 3 main functions include:
1. Transport of oxygen and nutrients toward and wastes away from cells of our body
2. Immunological protection of our body from foreign organisms and substances
3. Maintenance of homeostasis including the regulation of body temperature, blood pressure, electrolytes and water balance.
What are the common ailments of the circulatory system and their symptoms?
The most common ailment of the circulatory system is atherosclerosis, or hardening of the arteries. This condition can lead to heart attack or stroke. Sometimes there are no symptoms, but when the problem is severe it typically causes symptoms such as chest pain, shortness of breath, weakness, nausea, and sweating. The second most common circulatory disease is hypertension, or high blood pressure. High blood pressure is very often without symptoms and has been called 'the silent killer', so it is important to get regular blood pressure checks.
Where is the location of the circulatory organs?
The location of the organs are mainly in the ribs.the lungs are on the side and the heart is in the middle
What was the importance of the discovery of the circulatory system to the ancient Chinese?
The ancient Chinese discovery of the circulatory system contributed to their mastery of traditional medicine. These techniques are still used successfully by modern people of all nationalities.
How can you look after your circulatory system?
how to prevent circulatory ailments some ways of how to prevent this ailment is not to eat too much fatty foods and to always follow what the doctor is saying so that the ailment is to be cured....another is to qalways check the blood pressure because this also helps in knowing if there is an ailment of a person in the circulatory system
How many percent of people who died without Christ in there heart?
Since Jesus said, "Many there be which go in there" we have to assume there will be a lot. To narrow it down further, Jesus said, "Many will say to me in that day, Lord, Lord, have we not done many marvelous things in your name and he will say, Depart from me for I never knew you." Then, he said about heaven, "Few there be which go in there." So the obvious conclusion is, a majority of people will die without Christ and be lost forever in hell. Based on this, I would have to conclude that perhaps 75% of the people will die without Christ.
When someone died why would there fingernails be blue-gray in color?
When a person dies, circulation stops within a couple minutes after the last heart beat. Blood still in the vessels does not flow. Without circulation, the face becomes a pale blue-gray and even finger nails can show a blue-gray cast.
How does capillaries help them do their job?
Capillaries work in the same way as vessels and veins but they also help by receiving food molecules from the small intestine. And also if a vessel or vein get damaged, they can divert blood away from the injury to reduce blood loss.
What is the main function of the circulatury system?
The role of the circulatory system is to transport oxygen and other necessary nutrients all throughout the body. The main part of the circulatory system is the heart. The heart is the organ responsible for pumping blood throughout the body. This system has three types of blood vessels: The largest are arteries which go away from the heart. Next are veins which lead to the heart and are the second largest vessel. The smallest are capillaries which transport blood through tight spaces. Sometimes, red blood cells need to pass one by one though capillaries!Wow!
The role of the circulatory system is to circulate the blood to the whole body .... basically responsible for the blood flow in the body, oxygen and gases from and to the cells also nutrients and hormones are involved
Does the circulatory system make hormones?
The circulatory system does not produce adrenaline. That is the job of the endocrine system.
How are the red blood cells destroyed?
The spleen identifies "old" erythrocytes (RBCs) and destroys them. The life of an RBC is around 120 days.
The smallest vessels in the human body are capillaries. They are the blood vessels that absorb oxygen into the blood and returning blood cells that lack oxygen back into the heart and lungs to be oxidised.
What is the most formed elements in the blood?
Erythrocytes, or red blood cells, are the most abundant of the formed elements of the blood. The other formed elements are leukocytes (white blood cells) and thrombocytes (platelets).
erythrocytes (red blood cells)
Erythrocytes (red blood cells or RBCs)
platelets, for about 250,000-500,000 per mm3 of blood.
These are three integrated systems. The respiratory system exchanges blood gases, the most important of which is supplying the body with oxygen. The cardiovascular system carries these gases to the individual cells. The muscular system (the heart itself is a muscle also) keep the body in motion.
The atria are the upper chambers of the heart that receive blood returning from the body (right atrium) and the lungs (left atrium). They contract to push blood into the ventricles for efficient circulation.
The cardiovascular system includes the blood heart and lungs true or false?
False
The systemic circuit provides exchange of gases between blood and the rest of the body. The pulmonary circuit provides gaseous exchange between the lungs.
What body system takes in and absorbs nutrients and eliminates waste?
The digestive system both takes in and absorbs nutrients, and eliminates solid waste. The main organs are the mouth, esophagus, stomach, small intestine, and large intestine.
What are the functions of three major parts of circulatory system?
INTRODUCTION:
The heart is a spectacular muscular organ that beats every second, of every day. It is positioned behind the ribcage and between the lungs. It tilts slightly to the left. It also supplies your body with what it needs to live, fresh oxygenated blood.
Blood that is rich in oxygen appears red. Blood that is poor in oxygen appears blue.
Arteries are tough, elastic tubes that carry blood away from the heart. Veins carry the blood to the heart.
The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood. This process is called circulation.
THE HEART:
The heart is the most vital organ in the circulatory system. It is composed of 4 main sections: the right and left ventricle and the right and left atrium. The heart acts like a pump that forces the blood through an interconnecting system of vessels which eventually return to the heart. So this is your heart, your ticker, without it you wouldn't be here. It supplies your body with what it needs to live. You notice the heart in the picture above is two different colors: red and blue. The red is oxygen enriched blood from the lungs and the blue is oxygen deficient blood which has returned from the body. The heart is the pump that keeps this transport system moving.
The structure of the heart is divided into four main sections the left and right atrium and the left and right ventricle. The blood enters the heart from its long journey around the body through the superior and inferior vena cava into the right atrium. This blood has very little if any oxygen. Then it passes by the tricuspid valve into the right ventricle. After the right ventricle contracts, the blood is forced past the pulmonary semilunar (crescent shaped) valve, and into the pulmonary trunk which is an artery. The pulmonary trunk splits into the right and left pulmonary artery where the still oxygen deficient blood travels through the lungs. The blood becomes enriched with oxygen and travels back toward the heart. The blood enters the heart via the right and left pulmonary vein which come directly from the lungs. The blood then enters the left atrium. The bicuspid valve opens up and the blood falls into the left ventricle. The ventricle contracts and the blood goes rushing passed the aortic semilunar valve and into the aorta which is the largest artery in the body. Now the blood is on its way back to the body.
The heart pumps oxygen into the blood and collects carbon dioxide from it to be expelled through the lungs.
To see how big your heart is, make a fist. Your heart beats about 60-100 times per minute. Your heart beats every second, of every day. In one year your heart beats more than 30,000,000 times. In an average lifetime a heart will beat over 2,000,000,000 times. Our heart never stops for rest or repair. The heart weighs about 10 ounces, about as much as one of your sneakers. It is located in the middle of your chest tilted slightly to the left.
BLOOD:
The blood is the transport system by which oxygen and nutrients reach the body's cells, and waste materials are carried away.
Blood that is rich in oxygen appears red.
Blood that is poor in oxygen appears blue.
Blood is that sticky, red fluid that circulates throughout our bodies in veins and arteries.
Red blood cells carry oxygen from the lungs to all the cells of the body.
White blood cells are like soldiers protecting the body.
BLOOD VESSELS:
Blood leaves the left side of the heart and travels through arteries, which gradually divide into capillaries. In the capillaries, food and oxygen are released to the body cells, and carbon dioxide and other waste products are returned to the bloodstream.
Veins and Arteries
Arteries are tough, elastic tubes that carry blood away from the heart. As the arteries move away from the heart, they divide into smaller vessels. The largest arteries are about as thick as a thumb. The smallest arteries are thinner than hair. These thinner arteries are called arterioles. Arteries carry bright red blood! The color comes from the oxygen that it carries.
Veins carry the blood to the heart. The smallest veins, also called venules, are very thin. They join larger veins that open into the heart. The veins carry dark red blood that doesn't have much oxygen. Veins have thin walls. They don't need to be as strong as the arteries because as blood is returned to the heart, it is under less pressure.
Blood Vessels
The blood vessles are an network of interconecting veins and arteries and their sub catagories. They provide the pathway in which blood travles. The catagories from largest to smallest and back to largest are as follows:
Aorta Arteries Arterioles
Capillaries
Venules Veins Vena Cava
These are the different kinds of vessles in the body.
The AORTA is the largest artery in the body. It pertrudes out of the top of the left vetricle of the heart.
The ARTERIES are blood vessels which carry blood blood away from the heart. Usually the blood in arteries is deoxygenated except for in the pulmonary trunk. They have an elastic wall and their cell walls are thicker than veins. Arteries' walls are divided into three layers: the endothlium which is the innermost layer, see if you can guess the name of the middle layer... if you guesed the Middle layer then you are correct, it is a thick layer of muscle tissue. Alright go two for two; see if you can guess the name of the outer layer... that's right The Outer layer, and it is a tough elastic covering. As the arteries progressively get smaller and smaller they become called ARTERIOLES.
The CAPILLARIES are the smallest of the blood vessels. It is in them which gas exchanges take place. The capilaries are the bridge from the arterioles to the venules. The membrane of capilaries is very thin and permeable.
The VENULES are microscopic vessels that continue from the capillaries to merge to form veins.
ARTERIES are vessels that carry blood away from the heart.
VEINS are vessels that carry blood back to the heart.
PATH OF CIRCULATION:
Blood leaves the left side of the heart and travels through arteries which gradually divide into capillaries. The blood then travels in veins back to the right side of the heart, where it is pumped directly to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, and this renewed blood flows back to the left side of the heart, and the whole process begins again.
The majors parts of the circulatory system are the heart, arteries and veins. The heart pumps blood to the arteries. The arteries take the oxygenated blood to the muscles. The veins take blood back to the heart, which then releases carbon dioxide in the lungs
How the Blood Gets Around the Body
The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart, arteries, capillaries and veins.
As blood begins to circulate, it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for the cells in the brain and the body to do their work. The oxygen rich blood travels throughout the body in its system of arteries into the smallest arterioles.
On its way back to the heart, the blood travels through a system of veins. As it reaches the lungs, the carbon dioxide (a waste product) is removed from the blood and replace with fresh oxygen that we have inhaled through the lungs.
The circulatory system also known as the cardiovascular system is composed of the heart and blood vessels. Its function is to transport blood which contains oxygen and nutrients to all parts of the body. Also it carries cellular wastes away to be filltered out of the body.
The cardiovascular system includes the heart and the blood vessels, and the respiratory system contains those organs which are responsible for carrying oxygen from the air to the blood stream and expelling the waste product of carbon dioxide.
Blood CIRCULATES--circles--all around your body in about one or two minutes.
Inside the heart are four hollow chambers. Each chamber is a little pump. The pumping pushes blood all around your body.
MISCELLANEOUS:
The circulatory system is like a water system because the pipes are like the veins and arteries and the water plant is like the heart.

What do purkinje fibers carry?
Purkinje fibers usually carry information. They contain a few scanty, scattered, and more or less nonfunctional sarcomeres; they also contain a good deal of glycogen and a PAS stain will really make them stand out.
Purkinje fibers also transmit impulses rapidly from the atrioventricular node to the ventricles.
What is the molecule formed when hemoglobin binds to oxygen molecules?
It forms a compound called oxyhemoglobin. And when it combines with carbon dioxide it makes carboxyhemoglobin.
