sometimes not always but sometimes people say like some sort of pump
The heart is compared to the size of a closed fist because the average adult heart is about the size of their fist. This comparison provides an easy way for people to visualize and understand the approximate size of their heart.
No difference. The human heart structures or functions does not varies with gender.
yes because it is a human heart
A cardiologist
in comparison to a human heart, a frog heart consists of the right and left atrium, and one large ventricle, while the human heart contains two atrium chambers and two ventricle chambers.
Because they are just about the same size - and you can see your own fist.
The comparison of a human fist to the size of the heart is often made because both are roughly similar in size and shape, making it an easy visual reference. The heart is a vital organ, central to the circulatory system, and its health is crucial for overall well-being, which makes it a common point of focus in discussions about health. In contrast, other organs like the lungs or intestines have different shapes and functions, making them less intuitive for such comparisons. The fist analogy is particularly effective for emphasizing the importance of heart health in a relatable way.
Suck balls!!=]
probably because the "pigs" or "calf" heart is almost like the humans heart so they use heart almost or close to the human heart or maybe because the assignment says to use that specific heart "what I know from past studies is that the pig and calf is the same or almost exactly how the human heart is" hope that answered your question
It collects the blood returning from the body in the veins and sends it to the lungs.
The heart pumps blood to the body system which help to transfer food materials,hormones etc. from where they are produced to where they are used up.
Because the pressure on the left side of human heart is higher than the right side of human heart.
