Question

Body temperature - explained what happens elsewhere in the body to maintain the temperature?

Fluid, electrolyte, and pH balance - what other organs or systems are involved apart from the kidneys?

Elimination of waste - what other waste products are there apart from urine?

Maintenance of blood pressure - explain how blood pressure is maintained.

Protection against infection - how does the body function and process? what help is needed by the body?

Physical activity - explained what passive exercise is

Answer 1

Ans) The hypothalamus works with other parts of the body's temperature-regulating system, such as the skin, sweat glands and blood vessels — the vents, condensers and heat ducts of your body's heating and cooling system. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

- Body fluids are mainly water and electrolytes, and the three main organs that regulate fluid balance are the brain, the adrenal glands and the kidneys.

- All the metabolic wastes are excreted in a form of water solutes through the excretory organs (nephridia, Malpighian tubules, kidneys), with the exception of CO2, which is excreted together with the water vapor throughout the lungs. The elimination of these compounds enables the chemical homeostasis of the organism.

- Remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

- Defenses Against Infection- Natural barriers and the immune system defend the body against organisms that can cause infection. The immune system uses white blood cells and antibodies to identify and eliminate organisms that get through the body's natural barriers.

- Passive exercise: Movement of the body, usually of the limbs, without effort by the patient.
