Respiratory Functions and Breathing Mechanics

Question 1

Respiratory Function

Answer 1

Gas exchange-oxygen in, CO2 out

Enables person to breathe Inhalation

Question 2

Breathing, or inhalation

Answer 2

mechanism that provides oxygen to the body. Without oxygen, cells are unable to perform their functions necessary to keep the body alive

Question 3

inspiration

Answer 3

Diaphragm

known as chest cavity, this dome-shaped structure flattens when it contracts

Question 4

Breathing process

Answer 4

rib cage moves outward, allowing outside air to be drawn into the lungs. During relaxation, the diaphragm returns to its dome shape and the rib cage moves back to its natural position. This causes the chest cavity to push air out of the lungs

Question 5

Respiratory system-2 parts

Answer 5

Air Conduction

Gas Exchange

Question 6

Air Conduction

Answer 6

Air is delivered to the lungs. This region consists of the upper and lower respiratory tract—specifically, the larynx, trachea, bronchi, and bronchioles

Question 7

Gas Exchange

Answer 7

takes place between the air and the blood. This portion includes the lungs, alveoli, and capillaries.

Question 8

Additional Oxygen info

Answer 8

Oxygen from the air enters the body through the respiratory system. But the cardiovascular system circulates oxygen throughout the body via the blood

anatomical structure allows blood to absorb oxygen and transport it through a network of blood vessels to cells in various tissues throughout the body

During the process of gas exchange, the blood system absorbs carbon dioxide from cells and carries it to the respiratory system, where it is exhaled from the body

Question 9

Respiratory/Cardiovascular/Nervous Relationship

Answer 9

work to maintain blood gas and pH homeostasis

When there is too much carbon dioxide in the blood, it is acidic (that is, its pH value is too low)

f there is not enough carbon dioxide in the blood, it will be too alkaline (its pH value will be too high)
