Heart

A cats heart has four chambers, like humans.

Roundworms do not have hearts, skeletons, nor blood vessels. Roundworms belong to the phylum Nematoda. This group contains different types of animals like the hookworm and pinworm.

measurement of lung function through spirometry yielding values including FEV1, FVC, FEV1/FVC ration PEF and FEF 25-75: 50, 75 aned soemtimes 85 % of predicted value

be honest the way you touch it the heart can damage

there are 4 chamber in the heart the left and right atria and the left and right venticle

One is no more important that the other they both rely on the other to function properly. For example with out the lungs there would be no oxygen getting into your body but without the heart the oxygen wont be able to get to the rest of your body.

Turbo hustle

You can prevent heart attacks by eating healthy and most precisely fruits

there are 10 fruits you can eat to prevent heart attacks.

fruits like:

1.Apples

2.Avocados

3.Strawberries

4.Berries

5.Pinneaples

6.Tomatoes

7.Pomegranade

8.Grapes

9.Watermelon

As far as I am aware it doesn;t have special name.

Answer:

They don't have hearts or even an arterial system (veins, arteries). They have an "air system" which is a set of open tubes running through the body from openings on the body called spiracles. It's highly efficient for very small living creatures; it is used by a lot of insects. The problem with it for larger animals is that there is nothing to force higher rates of oxygen when necessary to parts of the body so the system is limited by movement (think of sharks who cannot stop and just float - they don't force water past the gills, their movement forces water through the gills. If the shark stops, he stops breathing -- BAD!) Faster movement can cause faster oxygen flow, to a limit, then the air ceases to flow (turbulence has set in) and oxygen deprivation sets in. {Yay us, boo mosquito.}

Well, actually a pigs heart genetically has the closest resemblance to a human heart, in fact very little is different from a human to a pigs heart, and this is why we use there valves in human disorders. So to answer the question, a human has four chambers to its heart and so does a pig. A pig is a mammal and most mammals have a four chambered heart, so the previous answer is wrong. there are at least five chambers A frog's heart has three chambers, unlike humans who have fourchambers.

ahaha:)) uhm..yes!

Pulmonary semi-lunar

The ventricles are the lower heart chambers that contract to pump blood. The upper chambers, atria, also contract, but to a lesser degree.

No. Arteries carry blood from the heart to the rest of the organs, and veins carry blood back to the heart. All arteries have high pressure from being pumped by the heart so recently, and all veins have low pressure from travelling round the body for so long.

Most arteries carry oxygenated blood (except for the pulmonary artery, which goes to the lungs to pick up more oxygen) and most veins carry deoxygenated blood (except for the pulmonary vein, which has lots of oxygen from the lungs).

Ticks have four stages of development: egg, larvae, nymph and adult. "Seed tick" is the slang term for the larval stage. SO a seed tick is not species differentiated. The following link has a picture of all 4 phases.

Vitamins, fruits, veggies, stay as hydrated as possible (with water of juice). Have regular checkups with if primary physician, always best to catch symptoms ASAP. Aspirin or baby aspirin is good for your heart. oatmeal helps a lot too.

Deoxygenated blood is in the systemic veins. The pulmonary veins carry oxygenated blood to the heart to be pumped to body tissues.

It is to close the valve(keep it from bouncing/valve float)and keep the lifter on/followingthe cam. This is why race cams with radical lobes need 1000psi springs. The higher the rpm/ heavier the valvetrain the heavier the spring needed.

Some causes of heart murmurs can include a congenital defect in a heart valve, a hole in the wall of the heart, endocarditis, and many other medical conditions. Some symptoms of a heart murmur are shortness of breath, fainting, and pain in the chest area.
