What is the difference between cow's and human's circulatory systems?
There are many differences between cow's and human's circulatory systems. The cow system has to work around 4 stomachs for example.
Can you hear your own carotid bruit?
Yes...I went to the Dr. complaining that I heard my own heartbeat 24/7. He did an exam using a stethascope on my neck and heard the "whooshing"sound. I now have to go to the hospitol for an ulstrasound.
What is the volume and pressure inside the left ventricle at the end of diastole related to?
The related value is called "stroke volume" and is equal to the end-diastolic volume minus the end-systolic volume, i.e. the maximum volume (pre-beat) less the minimum volume (post-beat).
The typical volumes for the left ventricle are slightly smaller than those of the right ventricle, but the stroke volume may be slightly greater.
Human circulatory system is a double circulatory system (two times) because blood passes through the heart twice in a complete circuit. (for oxygenated blood and deoxygenated blood)
There are two types of circulatory system in human beings :
1.pulmonary circulatory- blood circulates from the heart to the lungs and back to the heart
2.systematic circulation- blood circulatea from the heart to other organs and back to the heart.
The human heart will undergo over 3 billion contraction cycles
What are the surgical treatments for carotid stenosis?
The first approach is known as microsurgical carotid endarterectomy . The second approach is termed endovascular angioplasty and stenting.
Which does not belong pulmonary trunk vena cava right side of heart left side of heart?
left side of the heart
Yes, it is since the infection is in the entire body and it is called sepsis. It does depend on the bacteria or virus that is involved but still can be deadly. There are a lot of different microbes which can cause sepsis. Bacteria is the leading cause of sepsis but fungi and virus can also cause it. Infections in the kidneys and bladder (UTI), lungs (pneumonia), skin (cellulitis), appendicitis, meningitis and others can lead to sepsis. Infections developed after surgery may also cause sepsis. Bacterial infection is a medical emergency. A person having sepsis should be treated in the hospital specifically in the intensive care unit.
Where is oxygenated blood found?
Oxygenated blood is found in the arteries of the circulatory system, which carry blood away from the heart to the rest of the body. The oxygenated blood is then distributed to the tissues and organs for cellular respiration.
Why do you think the strongest muscle is in your heart?
Not "in your heart," but rather the heart itself.
The heart is the strongest muscle because:
1) It's working non-stop and is always getting exercised.
2) It is so essential. It keeps the whole body alive. You can live after losing any other muscle, but not after the heart-muscle stops.
How the anatomical design of the hepatic circulation serves its function?
You have capillaries in the gastrointestinal tract. The capillaries unite to form the veins. You have again formation of the capillaries in the liver. Here the blood has to pass through the sinusoids to the central vein. The blood is accompanied by blood from the hepatic artery. The portal blood carry the nutrients. The hepatic artery carry the oxygen. The liver cells are metabolically active. They need both to perform the desired function. So you have very unique arrangement in the liver. So you have capillaries - veins - capillaries in portal circulation.
Blood flow from the mitral valve to the bicuspid valve?
The mitral and bicuspid valves are the same thing.
Does heart muscle has the same structure as the arm muscle?
No heart muscles are different from arm muscles. They are not same either structure vise or by function wise , both have seperate entity and function.
Do arteries return blood from the capillaries to the heart cells?
this question is all mixed up. you must understand that blood leave the heart and goes to the body by travelling through the arteries(except the pulmonary artery) then is distributed to individual cells by the arteries then goes back to the heart through the veins(except the pulmonary vein).
so in the case of the heart cells, blood accesses the heart through the coronary artery, goes to the individual cardiac muscle cells by the capillaries and and then back to the hearth through to coronary vein.
Why is that you can take you blood pressure reading 3 times and get 3 different results?
Because blood pressure changes.

"Waltham-Lowell System was a labor and production model employed in the United States, particularly in New England, during the early years of the American textile industry in the early 19th Century.
The system used domestic labor, often referred to as mill girls, who came to the new textile centers from rural towns to earn more money than was possible at home, and to live a cultured life in "the city". They lived a very regimented life - they lived in company boardinghouses and were held to strict hours and a rigid moral code.
As competition in the domestic textile industry increased and wages subsequently fell, strikes began to occur, and with the introduction of cheaper imported foreign workers by mid-century, the system proved unprofitable and declined."
Difference between plumonary circulation coronary circulation and systemic circulation?
systemic circulation carries blood from the heart to the body (with the exception of the lungs) and back again. Oxygenated blood is carried by the aorta from the left veintricle of the heart to the body tissue through the capillaries. The venous system then transports deoxygenatedblo from the body to the hearts right atrium via the vena cava.
The reproductive body parts are covered in order to prevent the person from being rendered sterile.
The audio system doesn't work in the back of the Yukon XL?
I would spend the 15 dollars (or so) on a Haynes Repair manual vailable at most auto parts stores or consult the online resources of your local library. There is a plug from the back of your radio that carries all the power (radio, clock power anntena and speaker outputs. You'll find the wiresare color coded but that's not hard top figure out. I'm thinking your problem is under the carpet; probably under the seats under the carpet. Look for a connection plug joining the wires from your radio to an extension that leads to your speakers. My guessis this plug has some corrosion or possibly has been pulled apart. Clean with contact cleaner or WD-40 and joi the plugs back to gether. Maybe a wrie was pulled from the plug, you'll have to fix this.
Where can you find a 94 jetta gl alarm system diagram?
You can find a 94 Jetta GL alarm system diagram in the vehicle's owner's manual. You can also find it at local auto stores.
What is the function of the circulatory system of a gymnast?
the function of circulatory system of a gymnast is it supplies blood to all our body fast and removes toxin which are present in our body.
Who discovered circulatory system?
The heart, arteries and veins of the circulatory system were all well known t people from prehistoric times. Its true function was not known, however, until William Harvey (April 1, 1578 - June 3, 1657) showed that it recirculated the same blood throughout the body.
What is a multilateral system?
Multilateralism is an international relations term that refers to multiple countries working in concert. Most international organizations, such as the United Nations and the World Trade Organization, are multilateral in nature. The main proponents of multilateralism have traditionally been the middle powers such as Canada and the Nordic countries. Larger states often act unilaterally, while the smaller ones may have little direct power at all in international affairs aside from participation in the United Nations (by consolidating their U.N. vote in a voting bloc with other nations, for example). The converse of multilateralism is unilateralism in terms of political philosophy.
