What is path of blood flow in heart?
The deoxygenated blood enters the right atrium from the superior and inferior vena cava. The deoxygenated blood then goes through the tricuspid valve into the right ventricle. From the right ventricle the deoxygenated blood flows through the pulmonary valve to the lungs to be oxygenated. The blood goes to the lungs through the pulmonary arteries to get to the lungs. At the lungs diffusion (movement of things between a higher concentration and a lower concentration) occurs and the higher concentration of oxygen in the lungs (more specifically alveoli) goes to the lower concentration of oxygen in the capillaries (extremely small blood vessels). The same thing occurs with Carbon Dioxide except it is going from the capillaries from the lungs. The now oxygenated blood flows from the lungs to the left atrium through the pulmonary veins, where it is sent to the left ventricle through the mitral valve. From the left ventricle the oxygenated blood goes through the aortic valve, into the aorta, and all throughout out the body.
Why are arteries buried deep in the body?
Due to ventricular systole, the blood flows through arteries under pressure in a jerky motion. So it is better for the arteries to be placed deeply as lot of blood loss can occur when damaged if they are placed close to the skin.
What are artrioventricles?
Atrioventricular valves ar the valves in the heart that lie between the atria and the ventricles. These valves stop the the blood from flowing back (in the wtong direction) from the ventricles into the atria. There are two atrioventricular valves, on the right is the Tricuspis and on the left is the Bicuspid or Mitral valve.
How can you tell if your girlfriend is a pathological liar?
you know your friend is a pathological liar basicly if they always have a tendency to lie and if they lie their way to deep in the lie to tell the truth. or if they constantly lie to cover up another lie and so on.
What are the chambers of the heart and their descriptions?
The heart has 4 chambers. The lower 2 are called ventricles and have thicker muscular walls than the upper 2 called the atria. The septum which divides the hearts two sides is made mostly of muscle.The atria receive blood from all parts of the body;the ventricles pump blood into circulation. As well as having the 4 chambers it also has 4 valves to control blood flow. They have the same structure but differ in certain details.The 2 atrioventricular valves lie between the atria and ventricles. The mitral valve on the left side has 2 cusps (bicuspid) while the right side counterpart has 3 cusps (tricuspid). Two semilunar vales are the exits from the ventricles, the pulmonary valve between the right ventricle and pulmonary artery and the aortic valve between the left ventricle and the aorta.
Are veins or arteries more superficial in the body?
Veins tend to be more superficial, meaning they lie closer to the surface of the skin. Arteries usually, but not always, run deeper in the tissue than veins.
Why do large veins lie next to bones?
Large veins lie next to bones mostly for protection. Large veins lie next to bones mostly for protection.
What is the difference between an atery and a vein?
There is no transportation system in any city that can compare in effeciency with the circular system of our body. If you can imagine two systems of pipes, one large and one small, both meeting at a central pumping station, you will have an idea of the circulatory system. The smaller pipes go from the heart to the lungs and back, while the larger ones go from the heart to the various other parts of the body. These pipes are called arteries, veins and capillaries. Arteries are vessels in which blood is carried away from the heart. In veins,the blood is coming back to the heart. In general terms, arteries are carrying pure blood to various parts of the body, and the veins are bringing back blood loaded with waste products. The pumping station is of course the heart. Arteries lie deep in tissues, except at the wrist, over the instep, at the temple and along the sides of the neck. At any of these places the pulse can be felt, which gives the doctor an idea of the condition of the arteries. The blood in arteries is bright red in color and moves through in spurts. Veins lie closer to the surface of the skin, and the blood in them is much darker in color and flows more evenly. Veins have valves and intervals all along their course. Fact File: Blood contains red and white blood cells that float inside a liquid called plasma. It also contains thousands of different substances needed by the body. Blood carries all this things round the body and also removes waste products.

Does love bite cause headaches?
Only in some sensitive spots or near veins and arteries. This is common around the neck. If you are feeling very light headed, lie down. If it persists, consult a doctor.
How do you diffrentiate between a vein and an artery?
Arteries are buried much deeper than veins. Near the heart you can see them throb with the pulse. If you pierce one, the blood spurts out, sometimes in rhythym with the heartbeat. The blood is bright red. Veins are darker in color, don't show a pulse, and don't spurt, but rather drain more slowly. The blood is a darker color from dark red to purple or maroon. In a first aid context, look for the bright red color and stop the arterial bleeding first, best with direct pressure.
What types of veins are there?
There are three major categories of veins: superficial veins, deep veins, and perforating veins. All varicose veins are superficial veins; they lie between the skin and a layer of fibrous connective tissue called fascia.

What has the neuron got to do with the brain?
So, neurons are in the blood vessels. blood vessels originate from the brain. So, the main source of the cardiovascular system starts with the brain. Then arteries and veins spread all over the human body. and neurons lie within the vessels.
What does O2 and nutrients deliever to the myocardium by what?
The myocardium receives its oxygen and nutrients from the coronary arteries, which lie on the outside of the heart.
Where does the pulmonary valve lie between?
The right atrium and the left atrium. It actually lies between the right ventricle and the pulmonary artery, where it prevents the backflow of blood from the artery back into the heart during diastole (the resting period of the heartbeat)
What are ways the body cools itself in hot weather and heats itself in cold weather?
In cold weather, the arteries and veins nearer the skin have less blood passing through them and the ones further into the body have more thereby retaining heat. The hairs on most parts of your body also stand up to trap a layer of air for insulation. The body when cold frequenly shivers. This is a bodies way of trying to produce movement which in turn generates blood flow and heat transfer. In warm weather, the opposite happens. Hairs lie down and the arteries and veins nearer the skin fill up thereby letting heat energy conduct radiate out of the body. The body has pours. These secret sweat which acts as a cooling agaent.
