Q

Explain what occurs in the body as a result of respiratory compromise.

A

Respiratory clinic promise is the inability of the body to move gas effectively. It occurs when either ventilation or respiration is impaired. The heart and brain cells cannot survive without a constant supply of oxygen, and will die in minutes.

ATP is a nucleotide that’s the main source of energy for the cell. ATP is made in the mitochondria where glucose and oxygen are manipulated to create ATP.
Must have glucose and oxygen to make ATP.

66
Q

68
Q

Be familiar with what the different body systems do. (what does the stomach do? What organ secretes insulin? What are the jobs of the small and large intestine?)

A

The stomach produces approximately 1.5 L of gastric juice daily. The primary function of the stomach is to receive food in large quantities, intermittently, restore it, and provide for its movement into the small bow and regular, small amounts.

The pancreas is the organ that secretes insulin, which happens in the portion of the gland the islets of Langerhans-is endocrine

Large intestine is the portion of the digestive tube that encircles the abdomen around the small bowel, consisting of the cecum, the colon, and the rectum. It helps regulate water balance and illuminate solid waste.

Small intestine is the portion of the digestive tube between the stomach and the cecum, consisting of the duodenum, jejunum, and ileum.

69
Q

What is the driving factor that influences us to intake a breath? (the level of what gas in our body triggers our brain that we have to breathe?)

A

Co2
Carbon dioxide

70
Q

What is the difference between ventilation and respiration?

A

Respiration:
the inhaling and exhaling of air; 20 physiologic process that exchanges carbon dioxide from fresh air

Ventilation:
the movement of air between the lungs and the environment

71
Q

What structures make up the upper airway and the lowerairway?

A

The upper airways are made of the nose, mouth (oral cavity), tongue, jaw (mandible), pharynx, and larynx. The larynx is typically considered the dividing line between the upper and lower airway.

The lower airway consist of the larynx, trachea, bronchial tree, and the lungs.

72
Q

What is the purpose of the epiglottis?

A

The epiglottis is a flap which allows air to pass into the trachea but prevents food and liquids from entering the airway under normal circumstances

73
Q

Where in the lungs does respiration occur at?

A

Respiration
The exchange of oxygen and carbon dioxide occur within the small one Alveoli

74
Q

During inhalation, what does your diaphragm do?

A

During inhalation:
Your diaphragm contracts, and moves downwards.

75
Q

During exhalation, what does your diaphragm do?

A

During exhalation
your diaphragm and rib muscles relax, reducing the space in the chest cavity.

76
Q

What is considered a normal tidal volume for an adult?

A

Generally, 500 mL in an adult

77
Q

What is dead space volume and how much is it for an adult?

A

That space is the portion of the respiratory system that has no alveoli, and, therefore, little or no exchange of gas between air and blood occurs
Usually 150ml

78
Q

What process is involved in the exchange of gases during respiration? (Like how do they move - osmosis, diffusion, facilitated diffusion, or active transport?)

A

In the capillaries, oxygen (O2) passes from the blood to the tissue cells, and carbon dioxide (CO2) and waste pass from the tissue cells to the blood.

79

A

The SA node

83
Q

What is considered the strongest part of the heart? What is the weakest.

86
Q

What is one thing an artery will always do?

A

The arteries carry blood from the heart to all body tissues.

87
Q

What is one thing a vein will always do?

A

Veins collect oxygen-poor blood throughout your body and carry it back to your heart. The other purpose is to carry oxygen-rich blood from your lungs to your heart.

88
Q

Arteries usually carry what type of blood?

A

Oxygenated blood
Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.

The amount of blood moved in beat is called stroke volume (SV)

92
Q

What is cardiac output?

A

Cardiac output is equal to heart rate times stroke volume

93
Q

What does top number on a blood pressure called and what does it represent?

A

The systolic
When the cardiac muscle of the left ventricle contracts

94
Q

What does the bottom number on a blood pressure called and what does it represent?

A

Diastolic
When the muscle of the ventricle relaxes, the ventricle fills with blood.

A

Pulse Pressure

96
Q

97
Q

What is shock?

A

Recall that shock (hypoperfusion) is a condition in which organs and tissues receive an in adequate flow of blood and oxygen, or perfusion.

98
Q

What are the different branches of the nervous system?

A

The central nervous system is made up of the brain and spinal cord.
The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

99
Q

What are the two branches of the peripheral nervous system?
