The heart is the structure that pumps blood to the rest of the body. It’s composed of and surrounded by four kinds of tissues—co

nnective, muscle, epithelial and nervous tissues. How do you think the four tissue types support the function of the heart? How do the different tissue types support the idea that systems of specialized cells are critical for body functions?

Connective tissue holds the heart in place as the body moves. Muscle tissues and nervous tissues work together to pump the heart, enabling it to push blood through the circulatory system. Epithelial tissue protects the heart when the body moves so that other structures don’t damage it. The different types of tissues are made of different types of cells, and each tissue performs different functions for the body. These facts support the statement that systems of specialized cells are important for all body functions.

<span>Humans—and other large multicellular animals—are made up of four basic tissue types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. 
</span>Epithelial tissue<span> consists of tightly packed sheets of cells that cover surfaces—including the outside of the body—and line body cavities. For instance, the outer layer of your skin is an epithelial tissue, and so is the lining of your small intestine.</span>
Epithelial cells are polarized, meaning that they have a top and a bottom side. The apical<span>, top, side of an epithelial cell faces the inside of a cavity or the outside of a structure and is usually exposed to fluid or air. The </span>basal<span>, bottom, side faces the underlying cells. For instance, the apical sides of intestinal cells have finger-like structures that increase surface area for absorbing nutrients.
</span>
Connective tissue
 consists of cells suspended in an extracellular matrix. In most cases, the matrix is made up of protein fibers like collagen and fibrin in a solid, liquid, or jellylike ground substance. Connective tissue supports and, as the name suggests, connects other tissues.

Muscle tissue<span> is essential for keeping the body upright, allowing it to move, and even pumping blood and pushing food through the digestive tract.</span>

Nervous tissue<span> is involved in sensing stimuli—external or internal cues—and processing and transmitting information. It consists of two main types of cells: neurons, or nerve cells, and glia.
</span>
All of these tissues are essential in keeping the body running, including the cardiovascular system in which the heart is involved. All of these tissues play a key role in maintaining the function of the heart, whether it be indirectly, or directly, each of these will keep your heart sustained, but without them you wont live long lol. 
Hope this helped.

The nuclear envelope disintegrates during _____.
Shkiper50 [21]

Answer is prophase.

Prophase is the first phase of mitosis (a method of cell division). During this phase the chromatin material in the nucleus condenses, coils and becomes compact, resulting in the formation of visible chromosomes. The replicated chromosomes attains an X shape and are called sister chromatids. The nucleolus disappears. The nuclear envelope disintegrates resulting in the release of the contents of the nucleus into the cytoplasm.
