Answer:
Greater than the pressure in the atmosphere.
Explanation:
Air moves from the region of higher pressure to that of its lower pressure. To move the air out of the lungs during exhalation, the intrapulmonary pressure (pressure inside the lungs) is increased above the atmospheric pressure. This is achieved by relaxation of the diaphragm and the external intercostal muscles relax. The chest and lungs recoil and the alveolar pressure inside the lungs increases above atmospheric pressure. This pressure gradient allows the air to move outside the lungs during exhalation.
Answer:
The answer is Atom.
Explanation:
The atom is the smallest constituent unit of matter that has the properties of a chemical element and that it is not possible to divide by chemical processes. The atom is formed by a nucleus with protons and neutrons and several orbital electrons (subatomic particles); whose number varies according to the chemical element. Atoms combine to form molecules that then interact to form solids, liquids and gases.
Answer:
<em><u>Homeostasis</u></em>
Explanation:
One function of the hypothalamus is to <u>regulate body temperature</u> known as homeostasis. Hypothalamus <u>maintains the body temperature to a normal temperature of about 37°C.</u> When you step out without the jacket in cold, your body temperature fall to 37°C. When the hypothalamus senses that you are too cold, it sends signals to your muscles that make you shiver and create warmth. This is called maintaining homeostasis.
