Heart

The 2 modes of blood transport are the veins and arteries.

The way I use to remember is A is for away, so therefor arteries take blood away from the heart and veins go to the heart.

Veins NORMALLY carry oxygen poor blood

&

Arteries NORMALLY carry oxygen rich blood

The atrioventricular (AV) node which is located in the right atrium. From there is travels down the septum, also called the atrioventricular bundle, and then spreads to all parts of the ventricles via the Purkinje fibers.

After recognizing the signs, immediately dial 911 so the EMTs and Paramedics can get on their way as soon as possible. If possible, and if the victim is conscious, give him or her an aspirin (if over 18 and not allergic to aspirin) and put them in a position that will keep them safe if they were to become unconscious. Tell them to chew the aspirin as this makes it work more quickly. Sitting them up in a reclined position works best. If they have any restrictive clothing or jewelry, remove it. Talk to the victim and assure them that help is on the way. If anything changes with the victim, such as breathing difficulties, change in color of lips/fingers, or if he/she becomes unconscious, immediately have someone redial 911. If he or she loses consciousness, move the victim to the floor, flat on their back. Begin CPR. If you don't know how to do this, take a course. It will be helpful to you in the future. Follow the ABCs before you perform CPR: Make sure they have an open Airway: tilt their head back and their chin up to maintain unrestricted airflow. Check to see if they are Breathing: Put your ear over their mouth and listen for breath sounds, while looking at their chest to see if it is rising. Now check for Circulation: take their pulse on the side of their neck. Give this information to the 911 dispatcher or Paramedics when they arrive. Finally, make sure the victim gets to the Emergency room as soon as possible to begin appropriate medical care. Lifesaving drugs and procedures will be available to the patient and chances for recovery are increased when you can get the patient to the ER as soon as possible.

No, they are very different. The cells that make up the liver need to perform a different job from the heart.

Arteries always carry blood away from the heart. This an artery. Since it is going to the lungs to pick up oxygen and release carbon dioxide (dexoygenated) it is called the pulmonary artery.

This gun was manufactured for Sears Roebuck by the J. Stevens division of Savage Arms sometime between 1931 and 1941.

The tubes that carry blood are the blood vessels. They include capillaries, veins, and arteries.

Deer hearts are found in deer; and some shops.

Human hearts are typically only found in humans.

Generally the answer is yes.

Athletes for example tend to have slower heart rates than normal, and normal folks have slower heart rates than us old goats.

There is such a thing as a heart rate that is too low. If your heart rate is less than 50 or 60 beats per minute, and you are not a really fit, young, athlete, I think it would be wise to check with your physician.

As your muscles work harder, they need more nutrients. The brain tells the heart to beat faster to provide more nutrients to the muscles. You also breath heavier and more rapidly because your body needs more oxygen the harder you work.

The first successful open-heart surgery was performed on July 9, 1893 by Chicago surgeon, Daniel Hale Williams. A man suffering from a chest wound from a stabbing was brought to Provident Hospital, where Dr. Williams repaired the lining of the heart and the patient fully recovered within two months.

Most definately, there is a strong corelation with individuals having left arm pain and those also experiencing a heart attack (Myocardial Infarction). Although it is uncommon for this to be the only sign, and more common in males than females. Obviously chest pain is the best tell tale sign and typically would be a feeling of heaviness and or pressure. Unexplained perfuse sweating, nausea and vommiting I find to be other symptoms that are more frequent. In any of these situations one should immediately stop any physical activities and rest. If the pain and or symptoms don't go away within a few minutes seek medical attention immediately as the majority of treatments for any Heart Attack are time sensitive and the longer you delay will result in more Muscle Death. The majority of the "clot buster" drugs can only be given within the first 2-3hrs. in some places so don't gamble with your health and blame it on indigestion if your unsure go to the closest ER.

The right side of the heart pumps blood to the lungs to pick up oxygen. From the lungs it goes back to the left side of the heart, which pumps it out to the rest of the body. Blood then returns to the right side of the heart and starts the cycle over.

The heart has four chambers - left atrium, left ventricle, right atrium & right ventricle.

The left chamber holds oxygenated blood while the right chamber holds deoxygenated blood. The two sides of the heart are separated by an interventricular septum between the ventricles, and an interatrial septum between the atria.

The Pulmonary circulatory system carries deoxygenated blood from the right side of the heart to the lungs for oxygenation and brings the oxygenated blood back into the left side of the heart.

The Systemic circulatory system carries oxygenated blood from the left side of the heart to the rest of the body where the oxygen is depleted, and then back into the right side of the heart.

The function of heart pumping is to make blood to flow through the circulatory system, so that the body cells get their nourishment and keep you alive.

During your entire life, the power generated by the billions of heartbeats, is enough to send you to the moon and come back.

maybe your question goes this way..."how does oxygen enter the blood from the lungs?"Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, where it receives more oxygen.

animals like fish have a two chambered heart

An abnormal growth of tissue around a valve, composed of blood platlets, bacteria, and protein involved in clotting.

Many things like smoking, lack of exercise and bad diet increase the risk of getting heart disease. Your genetics are just another thing that could increase the risk of you getting heart disease.

A heart attack is an obstruction to the blood supply to the heart's own tissues. In the brain this is a stroke and in the lungs it is a pulmonary embolism. Depending on the severity of the blockage, and how long before treated, the tissues without blood supply will die.

low blood pressure causes what is called [reflex tachycardia] where the body realize that not enough blood is reaching the cells, so it stimulates the heart to beat more quicker

A persons heart rate is fast when a he or she is lying because they are worried whoever they are lying to might find out somthing their not supposed to. They are anxious so like all of us when were axious our heart beat gets faster! hope that helps x
