Heart
The heart is a major organ of the body that is found in the circulatory system. It pumps blood throughout the blood vessels. Questions related to the heart should be put here.

What is the correct path of blood in pulmonary circulation?
Right ventricle,artery,lungs,vein,left atrium,left ventricle
Why is the earthworms hearts not considered to be true hearts?
The hearts that worm's have are very different from the heart's that humans have. The worm equivalent of a heart is called the aortic arch and does not contain chambers or valves, and does not get oxygen-rich blood to the lungs. The aortic arches simply pump blood throughout the worm's body.
I honestly don't know. Ask jesus. He knows everything. He even knows the hair on your penis or vagina. He knows it all.
What do we call those people who have heart on right side of their body?
The individual is said to have 'Dextrocardia' (meaning right-heart).
What is the part of the tooth made up with blood and vessels?
I believe what you are refering to is known as the nerve, also refered to as dental pulp or pulp chamber. This is found deep inside the tooth under the dentin which is under the enamel (located on top of the tooth). The cementum is the outer layer that protects the dentin on the lower half of the tooth.
How does blood flow through the body to each individual cell and back to the heart?
it goes around the body in your arteries
What part of the heart is the squeezing chamber?
All four of the heart's chambers squeeze blood out into the corresponding chamber or artery. The right atrium pumps blood from the body into the right ventricle, and the right ventricle pumps that blood out of an artery that leads to the lungs. The blood then returns to the heart and is pumped by the left atrium to the left ventricle, which pumps the blood to the rest of the body.
blood is originally blue but when its exposed to oxygen it turns red
Will an EKG rule out a heart attack?
An EKG cannot rule out a heart attack. It gives a snap shot of the hearts electrical circuit at that moment. An EKG can show some changes indicative that there may be cardiac problems, as well as if you are actively having a particular type of heart attack (known as a STEMI).
But you can be having a heart attack with no EKG changes. The definitive answer comes from blood work done at the hospital.
What are two upper chambers of the mammalian heart through which blood enters?

bundling is a practice in sales that refers to packaging more than one item together, to induce customes to purchase a main product.
What valves allow the ventricles to fill?
In the human heart, each side (left and right) has a valve allowing blood to pass from the atrium into the ventricle, and preventing backflow.
The valve between the left atrium and left ventricle is the bicuspid valve (also called mitral valve).
The corresponding valve on the right is the tricuspidvalve.
How do you determine the heart rate on an EKG strip?
Remember a small box is 0.04seconds and the larger box is 0.2seconds
For regular rhythms the heart rate is calculated as follows:
1500 divided by the number of small squares between two consecutive R waves (works better for faster heart rates)
300 divided by the number of large squares between two consecutive R waves (only works with slower heart rates)
For irregular rhythms the heart rate can be calculated by multiplying the number of QRS complexes on the ECG by 6 (recall that at standard paper speed of 25 mm/s each ECG records 10 seconds of activity)
How can electrolyte imbalance control your heart function?
Electrolytes such as Sodium and potassium help the heart contract through a process called action potential. When the heart is at -60 MV the cell will open up allowing sodium into the cardiac cells causing a contraction. Look up action potential.
What does 'consent to rate' mean on a workman's comp bill?
Consent to Rate means that the insurance company must have the consent of the insured (i.e. by a signed form) to charge higher than the filed (with the State, if applicable in your state) rate.

To elaborate on the above answer, Florida is a good example of a state that allows Consent to Rate - these forms must be signed prior to binding. the resons for consent to rate would be Unable to Obatin Coverage at the filed rate, Unfavorable loss experience, unusual hazards or claims activity and such.

Why is it better to take your resting heart rate in the morning?
Because it relaxes the blood pressure and it's not good if it goes fast
FORMALIN CHAMBER
The new concept of sterilization system is lightweight transparent, corrosion proof and made from special grade of polymer with two sliding trays to ensure 100% sterilization of your surgical instruments.
For best result it is recommended to clean the instrument thoroughly before arranging it suitably in the try. Eight to ten formalin tabs should be kept exposed in the cabinet for overnight vapour saturation. Subsequently only twenty to sixty minutes of exposure will be required ensuring satisfactory sterilization. This time period, of course depends on the concentration of formalin. It is available in various sizes.
Is the blood that goes through the shark's heart oxygenated or deoxygenated?
Deoxygenated, it picks up oxygen when it passes the gills.
What effect does atropine have on heart rate?
Ventricular fibrillation, and supraventricular or ventricular tachycardia.
