The heart is part of the cardiovascular system and is made of cardiac muscle. cardiac muscle has special characteristics that distinguish it from other types of muscle tissue. which of the following are characteristics of cardiac muscle? check all that apply. one nucleus many nuclei striated not striated voluntary involuntary spindle shaped intercalated discs

The mentioned characteristics of the Cardiovascular system in this exercise are:

- One nucleus

- Striated

- Involuntary

- Intercalated Disks

Explanation:

All right, let's explain why all those characteristics are from the cardiovascular system.

First of all, the majority of the cardiovascular cells are build by only 1 nucleus. therefore, TThe cardiovascular system alls into the first one nuclei characteristic. Second, the cardiovascular system is managed involuntarily because we don't decide how to pump the blood and distribute it in the body, also it is controlled by the medulla oblongata in the brainstem right under the hypothalamus. These parts of the brain control the involuntary functions of our body. The cardiovascular tissue is also striated because its organization is defined by the I, and A bands which are layers of cell constituted by different proteins which provide them different colors. granting it the striated appearance. Finally, it also looks like an intercalated disk because the cells that build the cardiovascular tissue are inside collagen fibers and other substances so it can develop it's contraction movements.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
