what is the relationship between weight of animal and its heartbeat?

In simple terms, what I understand is that heart beat rate is a factor of rate of metabolism relative to body weight. Higher the rate of metabolism, higher will be the heart rate. Generally, larger animals have a lower metabolism rate compared to smaller animals and therefore larger animals have a slower heartbeat.

A normal resting horse has a heart rate of 38-40 beats per minute, foals (70-120 bpm), yearlings (45-60 bpm) and 2 year olds (40-50 bpm). Maximum heart rates can exceed 180 beats per minute, but a rate above 80 should be considered serious in most non-exercising horses.

As we've seen, humans have on average a heart rate of around 60 to 70 beats per minute, give or take. We live roughly 70 or so years, giving us just over 2 billion beats all up. Chickens have a faster heart rate of about 275 beats per minute, and live only 15 years. On balance, they also have about 2 billion beats.

Humans have a heart with two atria and two ventricles that pushes blood in one direction. Some animals have hearts similar to humans but, other animals have only one atrium and one ventricle or a cardiovascular system that can push blood in two directions.

When your heart beats it pushes blood around your body. This heart beat can be felt as your 'pulse' on your wrist or neck. Your pulse is measured by counting the number of times your heart beats in one minute. For example, if your heart contracts 72 times in one minute, your pulse would be 72 beats per minute (BPM).

Weighing of the heart By weighing the heart of a deceased person against Ma'at (or "truth"), who was often represented as an ostrich feather, Anubis dictated the fate of souls. Souls heavier than a feather would be devoured by Ammit, and souls lighter than a feather would ascend to a heavenly existence.

Puppies should gain 1-2 grams/day/pound of anticipated adult weight. Weigh the puppy daily for the first 2 weeks, then weigh at least weekly. A food scale typically works well for weighing the puppies.

Brain-body size relationship Brain size usually increases with body size in animals (is positively correlated), i.e. large animals usually have larger brains than smaller animals. The relationship is not linear, however. Generally, small mammals have relatively larger brains than big ones.

When stressed, heart rates will increase. Cats that suffer from heart disease, heart conditions (cardiomyopathy), or other diseases such as hyperthyroidism, may have increased resting heart rates of greater than 220 beats per minute in some cases.

The heart rate is the number of times the heart beats in the space of a minute. ... The pulse rate is exactly equal to the heartbeat, as the contractions of the heart cause the increases in blood pressure in the arteries that lead to a noticeable pulse. Taking the pulse is, therefore, a direct measure of heart rate.

Interacting with animals has been shown to decrease levels of cortisol (a stress-related hormone) and lower blood pressure. Other studies have found that animals can reduce loneliness, increase feelings of social support, and boost your mood.

Length is one dimensional whereas weight which depends on volume is three dimensional. Hence, there is thinking that weight of a fish is proportional to cube of the length of the fish. That is, there exists cubic relationship between weight and length of a fish. For an ideal fish which maintains the same shape b=3.

Which statement best describes the relationship between metabolic rate and size in animals? For all animals, the mass-specific metabolic rate decreases as the animal gets larger. Researchers conducted experiments to explore how gas exchange occurs in Atlantic salmon at various stages of life.

Weight plays a part. Weighing too much or too little can elevate a person's resting heart rate. Body size doesn't have a huge impact on pulse overall, but if a person is obese, they might see a higher resting pulse than normal, but usually not more than 100.

The adult cow has a heart rate of between 48 and 84 beats per minute. This can be assessed by using a stethoscope and listening over the left hand side of the cow's chest behind the cow's elbow.
