how are the heart and lungs positioned in a cat ? What is the apx size of the oregan?

the heart and lungs in a cat are pretty much similar to a humans. They are about the same size as very small plate, maybe about 5 inches long, 3-4 inches wide, and maybe only about 1-2 inches thick.  The heart is very near these, placed inbetween the lungs like in the human body.  The heart is somewhere between the size of a golf ball and a light bulb depending upon the size of the cat.

Snakes have a reduced or absent left lung; the right lung is long and extends along much of its trunk; it looks like a pink elastic and many-celled pantyhose.\n\nBoas and pythons usually have two functional lungs.

The first is surface area. The mammalian lung has a huge number pf alveoli compared to lung structures of reptiles and amphibians. The greater the surface area available for gas exchange, the more efficient will be the gas exhange.\n\nThe second requirement for gas exchange is assisted by the mamallian heart of four chambers as opposed to reptilian and many other hearts. There is an enormous amount of the circulatory system that passes directly to the pulmonary arteries and veins. Thus there is sufficient blood circulation in the lung area to remove oxygen and transfer it to the rest of the body.\n\nComparative biology will show far fewer alveoli in non-mammalian hearts (with the exception of birds). The other thing notable from compataive anatomy is that the mamallian heart (and that of birds) is a four chambered pump that does not mix unoxygenated blood with blood that has been oxygentated.\n\nSurface area and increased opportunities for deoxygenated hemoglobin to accept oxygen due to more efficient heart action.

In the domestic cat, Felis sylvestris, the cardiovascular system, compared to humans, is much, much smaller.

A 16 pound Coon Cat. This is where he spends 80% of his time sleeping, 15% eating, then the rest on cleaning. That is if he could reach all his parts.   But be advised not to look under there, he doesn't like strangers.

Not true.  He made this up.  Count the toes on your dog or cat; they have 4 plus a dew claw (that "thumb" on their heal).  Most mammals have 5 digits.  Our pinkies were going nowhere.

Kidney and or liver shutdown.  My neighbors cat had the same symptoms and the cat just passed last weekend.  Maybe poisoned from a plant or pesticide.  It's hard to know exactly what caused the death.  I am sorry for your loss.

Most larger pet stores sell small toothbrushes that will fit into a cat's mouth more easily, and some of the toothbrushes even slip over your finger.  There is also special flavored toothpaste that tastes better to the cat, although if you use a *tiny* amount of human toothpaste, it is OK too.  Just don't use the same amount that you'd use for yourself because it can upset their stomach.   Then just brush all the teeth carefully and rinse with a little bit of water.  Here is a very informative article:\n\nhttp://www.peteducation.com/article.cfm?cls=1&cat=1390&articleid=383

firstly the heart isnt in the middle as the answer above states, it is slightly offset.  the reason being is that there is no room in the centre, we have developed (through evolution) so that we need the lungs near the top, the oesophagus needs to be below the mouth and the heart is squeezed in where it can. more of  a design question than biology as other organs take precedence, the heart needs to be high in the torso to pump blood effectively, it needs to be close to the lungs as blood pressure to the lungs needs to be low to prevent haemmorhaging\n\nin other words its not in the middle because it wouldnt fit there

8 & 1/2 extra wide... I see your cat has a shoe fettish too.  So does mine.

That notch is known as the jugular or presternal notch.  It is the superior border of the manubrium, which is the uppermost portion of the sternum.\n\nIt also happens to be my kitty's favouritest place to put her little paw and apply her entire body weight to whenever she walks on my chest.  Her skill at placing the blow is quite remarkable, and I think she may just be practicing until one day she'll use her ninja-like abilities to assassinate me.

Head, thorax, abdomen. If you are in med school, this might not be the best place to get the answer.

In the human body, the heart is normally situated slightly to the left of the middle of the thorax, underneath the sternum (breastbone). It is enclosed by a sac known as the pericardium and is surrounded by the lungs. The apex is the blunt point at the base of the heart. A stethoscope can be placed directly over the apex and count the beats. In normal adults, its mass is 250-350 g, but extremely diseased hearts can be up to 1000 g in mass. It consists of four chambers, the two upper atria (singular: atrium) and the two lower ventricles.\n\nA septum divides the right atrium and ventricle from the left atrium and ventricle, preventing blood from passing between them. Valves between the atria and ventricles (atrioventricular valves) maintain coordinated unidirectional flow of blood from the atria to the ventricles.The ventricular systole consists of the contraction of the ventricles and flow of blood into the circulatory system. Again, once all the blood empties from the ventricles, the pulmonary and aortic semilunar valves close. Finally complete cardiac diastole involves relaxation of the atria and ventricles in preparation for refilling with circulating blood.\n\nThe function of the right side of the heart (see right heart) is to collect deoxygenated blood from the body and pump it into the lungs so that carbon dioxide can be dropped off and oxygen picked up. This happens through a process called diffusion. The left side (see left heart) collects oxygenated blood from the lungs and pumps it out to the body. On both sides, the lower ventricles are thicker than the upper atria.\n\nOxygen-depleted or deoxygenated blood from the body enters the right atrium through two great veins, the superior vena cava which drains the upper part of the body and the inferior vena cava that drains the lower part. The blood then passes through the tricuspid valve to the right ventricle. The right ventricle pumps the deoxygenated blood to the lungs, through the pulmonary artery. In the lungs gaseous exchange takes places and the blood releases carbon dioxide into the lung cavity and picks up oxygen. The oxygenated blood then flows through pulmonary veins to the left atrium. From the left atrium this newly oxygenated blood passes through the mitral valve (also called the bicuspid valve) to enter the left ventricle. The left ventricle then pumps the blood through the aorta to the entire body. Even the lungs take some of the blood supply from the aorta via bronchial arteries.\n\nThe left ventricle is much more muscular (1.3 - 1.5 cm thick) than the right (0.3 - 0.5 cm thick) as it has to pump blood around the entire body, which involves exerting a considerable force to overcome the vascular pressure. As the right ventricle needs to pump blood only to the lungs, it requires less muscle.\n\nEven though the ventricles lie below the atria, the two vessels through which the blood exits the heart (the pulmonary artery and the aorta) leave the heart at its top side.\n\nThe contractile nature of the heart is due to the presence of cardiac muscle in its wall which can work continuously without fatigue. The heart wall is made of three distinct layers. The first is the outer epicardium which is composed of a layer of flattened epithelial cells and connective tissue. Beneath this is a much thicker myocardium made up of cardiac muscle. The endocardium is a further layer of flattened epithelial cells and connective tissue which lines the chambers of the heart.\n\nThe blood supply to the heart itself is supplied by the left and right coronary arteries, which branch off from the aorta.

In humans, the Rhomboid is the shoulderblade (bone). I'm assuimng that in a cat, it would be the same. Good luck!
