Heart

The autonomic nervous system is then divided into the sympathetic division and parasympathetic division. The sympathetic nervous system responds to impending danger or stress, and is responsible for the increase of one's heartbeat and blood pressure, among other physiological changes, along with the sense of excitement he feels. The parasympathetic nervous system, on the other hand, is evident when a person is resting and feels relaxed, and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and geniturinary systems.

A heart attack is when an artery gets clogged and stops the blood.

This clog is normally like a bathroom sink that takes awhile before it gets completely clogged. Many many different things can cause the clog and/or help it get clogged quicker.

If an artery is almost clogged, a simple thing like an anxiety attack could rise the blood pressure just enough to complete the clog. So, YES it can, but it's NOT the main cause of the heart attack.

but mine is very cute also it is green and purple on my left wrist

THE HEART WORKS AS A WHOLE. One part cannot be more important than another.

bicuspid valve-->left ventricle of heart-->aortic valve-->ascending aorta-->

aortic arch-->thoracic aorta-->abdominal aorta-->right common iliac artery and /or left common iliac artery (abdominal aorta splits to form right and left common iliac arteries, adjust for which leg you follow) -->right external iliac artery -->right femoral artery -->right popliteal artery-->right anterior tibial artery-->right dorsal pedis artery-->right arcuate artery-->right dorsal metatarsal artery-->right dorsal digital artery-->arteriole-->capillary-->venule-->right dorsal digital vein-->right dorsal metatarsal vein-->right dorsal venous arch-->right great saphenous vein-->right femoral vein-->right external iliac vein-->right common iliac vein-->Inferior vena cava-->right atrium of the heart-->tricuspid valve

system is highly interconnected and alternative routes can be followed within the arteries and veins of the lower limbs

Hypertensive heart disease is any of a number of complications of arterial hypertension that affects the heart. It is like heart disease and heart disease is caused by high blood pressure.

Arteries. Or you might mean the aorta, the large artery coming directly out of the heart with others brancing from it.

The type of blood that goes though the Veins, Arterys and Capillaries is known as Red Blood Cell, which are also known as Oxygentated Cells.

yes it does i found the answer in a book.

Interestingly, none of the blood pumped THROUGH the heart provides circulation TO the heart itself. The heart muscle has its own set of arteries and veins (such as the descending and circumflex) from which to obtain oxygen and nutrients.

The two lower chambers of the heart are larger than the two upper chambers because they must generate the pumping force to move blood through the circulatory system. The left ventricle is larger than the right, reflecting the longer length of the systemic circuit.

a heart fails cuz god thinks that it is time for that person to go to heaven or hell wherever they go god thinks oit is the right place

The right side of our heart (right auricle)receives blood from the all body veins . i just learnt that in my work!

The size of the body. It takes longer for the blood to travel through the body and back to the heart where it needs to be pumped again in adults. Newborn's blood doesn't have to travel as far, and reaches the heart quicker.

A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.

The pericardium is the sac-like membrane surrounding the heart in the fetal pig, as well as in humans.

Tricuspud valve

The right atrioventricular valve in the human heart is called "tricuspid" because it has three (tri-) cusps (points). Looking at the valve from the atrium, it resembles three flaps.

The "flaps" are anchored by ligaments attached to the ventricular walls.

When presented with a training stimulus (or even the thought of a training stimulus), your heart rate will naturally begin to increase. This is the body's way of preparing for a stressful situation where its survival might be called into question. Understand that your body cannot differentiate between running around a track and running from a hungry lion--both are situations equally deserving of a rapid increase in heart rate to prepare it to "survive" the encounter.

The reason why your heart needs to beat faster as the physical demands on the body increase has to do with the concept of sufficiency. Generally speaking, your body only wants to perform the minimum amount of work to complete a task. When sitting around watching television, your organs and tissues do not require that much oxygen to continue functioning. Thus, your heart will beat slowly, conserving its strength. To the contrary, when exercising, your body requires much more oxygen to keep your body moving at rapid rate--causing your heart to speed up to meet the demands.
