describe the structures of the heart?

I found this great website http://www.yourpracticeonline.com.au/showcase.html\n\nIf you scroll right down to the bottom of the page there is a table in white, with a column labelled Heart, then under that click on the Heart Anatomy link. Sorry can't send you direct link - but this opens up a window with a superb anamation you can click around and even move around a 3d model of the heart. Then if you go through the presenation all the main items of the heart are shown.

Objectives: to identify the heart as the largest muscle in the body, to describe the heart's role in pumping blood to the lungs and to all parts of the body \n\n \nProcedures:  \nStudent Information: Ask students to identify the strongest muscle of the body. Allow students to give their ideas and then explain that the correct answer is the heart. Show students diagram of the heart and share the background information with them.  \nThe heart works day and night to pump blood through the circulatory system. \nThe heart consists of two pumps. \nThe pump on the right side of the heart sends blood to the lungs where the blood obtains oxygen. \nThe blood which has obtained oxygen then travels back to the heart where it is pumped to all parts of the body. \n\nI hope this helps...

The  heart.  I read about it in a book.  I forget the title.

In order for your heart to pump well, it needs oxygen, and it obtains it from the coronary arteries that are connected to the aorta. \nCoronary arteries - like any other organ or tissue, the heart needs oxygen. The coronary arteries that supply the heart are connected directly to the aorta, which ensures a rich supply of oxygenated blood.

the major parts of circulatory system are heart and blood vessels.\nthe blood vessels are of three types-1. arteries \n2. veins\n3. capillaries\nthe arteries carry blood mainly oxygenated blood from heart to different parts of the body.\nthe veins carry deoxygenated blood from all parts of the body to heart.\ncapillaries connect the arteries and veins...they are thin walled and allow the exchange of gases to occur across their walls.

basic anatomical structures such as 4 chambers and valves, the ability to compensate for high and low blood pressures (speed or slow down the rate), the ability to function independently, the ability to "communicate" with surrounding structures in a split second in order to facilitate rapid response, compatibility with the host, when a person's respiration's have ceased (RHC as it is known in the medical world) then the heart would cease as well, just as nature prescribed... and I'm sure there is a whole lot more that I don't have a clue about...

Question is a little vague......anatomy is structural and function is physiological, so I am not sure what your question really is; is it about anatomy or physiology or both? So RSVP:  Are you asking about the unique physiology or anatomy of amphibians?\n\nThey have many structures in common with the other tetrapod vertebrates, but also have unique structures as amphibians.  Plus each sub-class-type of amphibian (frogs-toads) vs (newts-salamanders) vs caecilians are each different.\n\nAll amphibians have their unique slimey scaleless skin through which they attain most of their oxygen and release their CO2 by diffusion, their 3-chambered heart with 2 atria and 1 ventricle, their external fertilization type reproductive system that has egg-larva-tadpole and adult.  Their respiratory system changes at each stage of development. As tadpoles they use their gills. As they metamorphose to adults,the gills are absorbed and lungs develop to breathe air although they lack a diaphragm and ribs (in most...some amphibians retain larval stage for their whole life...axolotyl). They have kidneys and bladder for excretory system; endoskeleton is bone and has most of the same bones as us, although some are fused (radio-ulna, fibulo-tibia; no skull protecting brain, unusual urostyle bone of pelvis.

The spiral of a screw. Its also the lines segmenting a worm.\n*fyi: earthworms have 5 hearts*

i would say cardiac muscles.

dear friend\n\nplease note that the heart is dual pump in other words there are right pump and left pump.\n\nthese right and left pump work together in a harmonious way\neach pump is made up of atrium and ventricle\n\nplease note that atria DO NOT pump blood to lungs instead they pump blood ONLY TO VENTRICLES. it is applicable for both the right and the left pump.\n\nthe ventricles on the other hand differ in their pumping destination\n\nright ventricle will pump blood only to LUNGS\n\nleft ventricle will pump blood only to THROUGHT OUT THE BODY\n\nwith regards \nkurian

hey! read a fish book. they always how a diagram of disecting parts or body anatomys. hint: for more info... go to this website:

draw a diagram of the system and where the blood goes when it goes in the heart etc. like show how it first goes into the right atrium than right ventricle than pulminary arteries then to the lungs to get oxygen then it travels back into the heart using the pulminary veins then its inside the left atrium then it goes through a valve into the left ventricle than to the aorta than to the rest of the body

Left ventricle into the aorta via the aortic valve, then through the body, eventually ending up in the vena cava, then the right atrium, through the tricuspid valve into the right ventricle, through the pulmonic valve into the pulmonary artery to the lungs, where it oxygenates, then comes back through the pulmonary vein into the left atrium, through the mitral valve and back to the left ventricle.
