What is the functions of the digestive, excretory, respiratory, circulatory, and lymphatic systems, and how do they interact to maintain the body's homeostasis?

Explanation:

Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body.

Homeostasis, which refers to the body's capacity to maintain a steady internal environment despite changes in the external environment, is a state that is maintained by the respiratory, circulatory, lymphatic, excretory, and digestive systems working in concert. Although each of these systems has a unique job to do, they are all interrelated and dependent on one another to keep the body running smoothly.

The digestive system is in charge of converting food into nutrients that the body can absorb. It consists of the liver, pancreas, small and large intestines, stomach, mouth, oesophagus, and stomach. After then, the circulatory system delivers nutrients to the body's cells.

The kidneys, ureters, bladder, and urethra are part of it. The circulatory system and the excretory system collaborate closely to move waste materials to the kidneys for filtering and expulsion from the body.

The respiratory system is in charge of supplying the body with oxygen and expelling carbon dioxide. It consists of the lungs, trachea, bronchi, nose, and mouth. The respiratory system collaborates with the circulatory system to eliminate carbon dioxide and provide oxygen to the body's cells.

Nutrients, oxygen, and waste products are moved throughout the body through the circulatory system. It consists of the blood, blood vessels, and the heart. To provide nutrition and oxygen to the cells and eliminate waste, the circulatory system collaborates closely with the respiratory and digestive systems.

It is the job of the lymphatic system to remove extra fluid from bodily tissues and transport it back to the circulatory system. It consists of lymphatic organs like the spleen and thymus, lymph nodes, and lymphatic arteries. The lymphatic system contributes to immunological function and aids in the body's defence against illnesses and infections.

Overall, through controlling the body's internal environment, these systems cooperate to preserve homeostasis. For instance, the excretory system eliminates waste while the digestive system supplies nutrients for the body. These nutrients and waste materials are delivered to and removed from the body's cells via the circulatory system. The lymphatic system helps the body fight infections while the respiratory system supplies oxygen for cellular respiration.

noah created a model of a glacier to help explain how glaciers change the surface of Earth. He froze two large blocks of ice. One block was pure water. The pther was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Noah's model explain how glaciers change Earths surface?

Before 1896, many scientists concluded that light could not pass through black paper. In 1896, Henri Becquerel observed that uranium salts could cause a plate covered by black paper to react as if light had reached it. How did this observation affect conclusions about light passing through black paper?

A- Scientists ignored Becquerel’s evidence because uranium is dangerous to use, so his study was not valid.

B- Scientists repeated Becquerel’s experiment until it no longer worked and reported that his conclusions were not valid.

C- Scientists had to revise their earlier conclusion because evidence from Becquerel did not support the original conclusion.

D- Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion.

Mark all that apply. What evidence is used to classify living things into groups.

A) cell type

B) habitat

In the ELISA procedure, first a protein sample is immobilized to a plastic well. Then, the antibody to the protein of interest is added, incubated, and the excess is washed out. Next, the detection antibody (which binds to the primary antibody) is added, incubated, and the excess is washed out. The last step is to add the detection dye (which binds to the detection antibody) to the wells and allow it to incubate. What do you predict the result would look like if you added the detection antibody first, then the antibody to the protein of interest

Anna went to her physician complaining of fatigue and swelling in her legs. She explained the doctor that she exercises often and does not drink water. She also revealed that she is smoker. Doctor sad that she was dehydrated, had edema and probably hypoproteinemia (low plasma protein concentration). He ordered some blood tests and ECG. ECG revealed that she had atrial fibrillation, which he said might explain her fatigue. Doctor advised her perhaps exercise more moderately, drink water and that she should definitely stop smoking.
