Answer:
Until the body stops functioning
Explanation:
It regulates temperature, glucose, toxins, blood pressure, and pH.

TemperatureThe body must maintain a relatively constant temperature. If it gets too hot, the body employs vasodilation to cool down. This dilates the blood vessels, allowing more heat to escape from them through the skin.
GlucoseThe body must regulate glucose levels to stay healthy. When glucose levels become too high, the body releases a hormone called insulin. When they become too low, the body converts the glycogen in the blood to glucose.
ToxinsToxins in the blood can disrupt the body's homeostasis. Thus, it signals the urinary system to ensure that the toxins are excreted.
Blood PressureThe body must maintain healthy levels of blood pressure. To do so, the brain sends signals to the heart to speed up or slow down according to the blood pressure.
pHThe lungs control the pH amount in the body. If pH levels become unbalanced, the lungs push more or less carbon dioxide out of the diaphragm. This can raise or lower pH levels in the body.</span>
A main type of muscle tissue is cardiac muscle.
<h3>What is the cardiac muscle?</h3>
Cardiac muscle or myocardium is a type of muscle tissue which is located in the heart, this type of tissue is what allows the contractions and resistance necessary to generate its function and send blood to all tissues and organs of the body.
The cardiac muscle is of the striated muscular type and together with the sinus and atrioventricular nodes is where the cardiac electrical impulses are sent to finally generate the heartbeat.
This type of muscle tissue is <u>only found in the heart</u>, since its characteristics are only useful for this important organ.
Therefore, we can confirm that a main type of muscle tissue is cardiac muscle.

<span>A communicable disease is a disease that can be
passed from person to person. It can also occur from an animal to a person or
vice versa. Airborne viruses, bacteria, blood, and bodily fluids can cause the
spread of these diseases. When things are infectious or contagious it also
refers to communicable diseases. The most common communicable disease is the flu,
which can easily spread in an enclosed environment with a recycled circulating
air (e.g. air-conditioning). Infectious disease caused by blood contact like
HIV/AIDs are also dominant in society. </span>
