Heart

It is a reduction in the size of a cardiac ventricle. This can be due to prolonged immobilization or from the tissue degeneration (wasting away), that follows with debilitating chronic illnesses.

Pilocarpine lowers the heart rate.

After blood leaves the left ventricle, it goes through the aortic valve to be pumped throughout the body.

Blood begins in the heart and flows through the:

aorta, common carotid, internal carotid, and ophthalmic artery

The ophthalmic has multiple branches which include the: central retinal artery posterior ciliary arteries. These two branches give the main supply of blood to the eye. The central retinal artery supplies the inner layers of the retina while the posterior ciliary arteries supply the outer layers of the retina.

The venous system drains from vortex vein ampullae into the choroid and back through the internal jugular to the heart. There are many images and more detailed information if you search for these specific parts of the vascular system especially on Wiki.

The chordae tendinae are fibrous bands of tissue extending from the papillary muscles in the ventricles to the cusps of the AV valves (tricuspid and mitral). They serve to prevent the leaves of the valves from being pushed into the atria during ventricular contraction, preventing backward flow of blood in the heart.

very,very samll and btw the ants heart its in its but

You should walk around or stetch so that your heart rate slows down very gradually, as that is the best way for the heart to adjust back to its normal pump rate.

The chordate classes that have 3-chambered hearts are Amphibia (the amphibians) and Reptilia (the reptiles). Humans and other mammals (birds too) have a four-chambered heart (left atrium, right atrium, left ventricle, right ventricle). Reptiles and amphibians have a left atrium, a right atrium, but only one ventricle (although the ventricle of reptiles has a small internal wall that divides it to some extent).

The pulmonary vein is the most important vein found in the heart because it brings oxygenated blood from the lungs into the left atrium.

they have to carry a battery pack that leads to their heart

coronary arteries

The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.

The first surgery on the heart itself was performed by Norwegian surgeon Axel Cappelen on the 4th of September 1895 at Rikshospitalet in Kristiania, now Oslo. The patient had the emergency surgery due to a knife wound and died a day later from infection.

The first successful surgery of the heart was by Dr. Ludwig Rehn of Frankfurt, Germany, on September 7, 1896, on another trauma patient.

Planned surgeries to correct defects in the great vessels that lead away from the heart were done in the early 1900's but true planned (i.e. not to repair trauma) surgeries of the heart were not commonly done until after WWII.

Well if you donate a eye, you wont die. If you donate a heart, youll probably live for about 3 minutes, though your probably dead befor you donate that.

Usually the Bridesmaid(s) only carry a bouquet and it's the Maid (single person) of Honor or Matron (married) of Honor that will not only carry her own bouquet, but hold the bouquet of the bride while the rings are being exchanged. Bridesmaids can be given the duty of holding the train of the Bride, but, flower girls can have this duty. If you just want other ideas as to what they could carry in lieu of a bouquet they could carry a Bible (if you are religious) with one red rose across it. If you are getting married in December white muffs (with a sprig of holly attached) are elegant. They can even carry candles, but it should be arranged properly so as not to start a fire )you don't want the Bridesmaid torching up for the evening! It depends on what your theme is. If you are getting married at the beach a bouquet can be made out of shells or a small basket full of decorative shells and clear, colored small glass bubbles.

dependent- human pulse rate

independant- tempo of music

ventricle

A lower resting heart rate is an effect of exercise and as an athlete is more likely to exercise more regularly then their resting heart is likely to be lower.

flutters day and night all day all night .i have a beta blocker and i am scared to death to take it

TRUE

Lesser circulation or the pulmonary circulation.

heart attacks commonly does not appear to people if they are healthy.people get heart attacks if they are in weakness state,hunger or thirst.
