Yes, the heart has a fibrous skeleton, which is a dense connective tissue structure that provides support and stability to the heart. Its primary functions include anchoring the heart valves, maintaining the shape of the heart, and serving as an electrical insulator that helps regulate the conduction of electrical impulses between the atria and ventricles. This organization ensures proper timing and coordination of heart contractions.
Quote from Wikipedia:"Cardiac skeleton (sometimes called "fibrous skeleton of the heart") refers to the structure of dense connective tissue in the heart that separates the atria from the ventricles. It is not a "true" skeleton, but it does provide structure and support for the heart, as well as isolating the electric charges that go through the heart by slowing them down enough to allow the atriums to contract before the ventricles so that the heart is much more efficient. It also allows the valves (bicuspid, tricuspid, semilunar) to keep open by giving them structural support."I do wonder why you didn't google it though...
Cardiac muscle pertains to the heart, so the function is as the heart pumps it pushes blood through the entire body. The blood circles through the heart and is shot into the body.
a heart tube acts as a "fliter" for the heart so that no impurities are pumped through the worms body
Bursae function to cushion joints so that bones don't wear down from rubbing against each other.
the already have a heart so their skull bone will form, then the skeleton, then their fingers and toes, then their skin and then their brain
The visceral skeleton is named as such because it supports the internal organs, also known as viscera. It provides structural support and protection for these organs, which include the heart, lungs, and digestive system.
That is so true! In fact it is the function of the heart valves.
No. The heart is an organ. Organs are made of more than one tissue. The valves of the heart are made of strong connective tissues. They are so strong and large they form what is called the skeleton of the heart and helps to give it shape.
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
No. If a patient got a "fake" heart, the fake by definition would not function. So, the patient would die if the surgeons put in a fake heart.
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
This is because mytotic cell division does not occur in the heart, so if damage is done the cells in the heart cannot repair themselves.
