Explanation

The kidneys are enclosed in a membrane called the peritoneum, which is a thin layer of tissue that lines the abdominal cavity.

The peritoneum supports and protects the kidneys, as well as other organs in the abdominal cavity.

Explanation

Thermoregulation is the ability of an organism to maintain its body temperature within a suitable limit, despite changes in the external environment.

This is a crucial function that allows cells, tissues, and organs to function properly.

Explanation

Halophytes are plants that are adapted to grow in coastal areas with high salt concentrations, such as salt marshes, mangroves, and seashores.

They have specialized structures and physiological adaptations to survive in these saline environments.

Explanation

• Removal of extra liquid water from plants is called guttation.
• The removal of water as vapor is transpiration.
• In biology, the general removal of excess water from the body is called excretion.
• In Chemistry: Known as Dehydration, the removal of a water molecule from a compound.

Explanation

The internal environment, also known as the "milieu intérieur," refers to the conditions within an organism's body.

Such as temperature, pH, and concentration of essential nutrients and waste products.

Explanation

Bronchitis is a condition in which the air passages (bronchial tubes) that carry air to and from the lungs become inflamed.

Explanation

Emphysema is a condition in which the alveoli at the end of the smallest air passages (bronchioles) of the lungs are destroyed.

Due to damaging exposure to cigarette smoke and other irritating gases and particulate matter.

Explanation

When CO2 levels in the blood increase, it triggers a response in the brain's respiratory centers to increase the rate of breathing.

This is because high CO2 levels indicate that the body is producing more waste products and needs to expel them through exhalation.

Explanation

The larynx (voice box) is located on top of the trachea (windpipe), which is a tube that leads to the lungs.

The larynx sits at the junction of the pharynx (throat) and the trachea, and it plays a crucial role in speech and breathing.
