Temperature
The 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.
Glucose
The 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.
Toxins
Toxins in the blood can disrupt the body's homeostasis. Thus, it signals the urinary system to ensure that the toxins are excreted.
Blood Pressure
The 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.
pH
The 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.
Answer:
i am pretty sure answer is A you got this
Answer:
Type Il cell.
Explanation:
Surfactant may be defined as the chemical that decreases the surface tension between the lungs. Pulmonary surfactant is the thin layer of fluid that increases the efficiency of gas exchange.
Type II alveolar cells of the lungs produces the surfactant. Lipida and proteins are the major constituent of the surfactant produced in the lungs. The surfactatnt is important for maintaining the integrity of alveoli.
Thus, the correct answer is option (e).
The number of new cases of a particular disease contracted within a defined population in a specified period is referred to as the incidence of the disease.
Population is defined as a group of similar type of organisms. This group of organisms live in the same area, they require same resources, have similar types of habits. The most essential criteria is that they can breed and reproduce among themselves.
Incidence of a disease is the data that provides information about the number of people affected by a disease at a given period of time. The likelihood of a person getting affected by the disease can be estimated using incidence.

Answer:
Phylum platyhelminthe
Explanation:
Although a few of the free living marine and terrestrial species are very beautiful, most species are not particularly attractive to the human mind. Their body is dorso-ventrally flattened.
They exhibit bilateral symmetry. They do not have a body cavity and are acoelomate. The movement of most platyhelminthes is using a wavelike motion that is controlled by longitudinal, circular, and oblique layers of muscle as they contract and relax simultaneously.
