Human Body Chapter 6 Quiz

The left lung has two lobes: upper and lower.

Two tubes branching from the trachea to supply air to the lungs.

Tiny air sacs in clusters where gas exchange occurs.

Smooth tissue covering each lung with two layers: visceral and parietal.

Potential space between the visceral and parietal pleura.

A dome-shaped muscle that aids in breathing and divides thorax from abdomen.

The movement of air between the lungs and the environment.

Muscles between the ribs that assist in expanding the thoracic cage during breathing.

Assisting a non-breathing patient using a bag-mask device.

The process of gas exchange providing oxygen and removing carbon dioxide.

Passive movement of molecules from high to low concentration.

Exhaled air contains 16% oxygen and 3-5% carbon dioxide.

Part of the brain that automatically regulates breathing.

Colorless fluid around the brain/spinal cord that cushions and filters.

Backup system that stimulates breathing when oxygen levels fall.

Maximum air expelled after normal breathing.

A state of systemic hypoperfusion affecting multiple systems.

Reduced blood flow, possibly localized to a specific region, like an arm.

The volume of blood the heart pumps per minute, typically 5 to 6 L.

Hormone secreted by the adrenal glands that stimulates heart and blood vessels.

Hormone that works similarly to epinephrine in managing stress and blood flow.

Receptors in blood vessels that cause constriction and increase blood pressure.

Receptors in the heart and lungs; influence heart rate and respiratory function.

Part of the autonomic nervous system that slows heart rate and reduces cardiac output.

Clumping of platelets in coronary arteries causing heart attack.

Prescribed to patients at risk for coronary artery disease to prevent heart attacks.

Increases blood flow by relaxing and dilating coronary arteries.

Always check blood pressure before administering nitroglycerin to avoid complications.

Nitroglycerin can cause fatal blood pressure drops when combined with these medications.

Can cause mild headache or burning sensation under the tongue after administration.

Wait 5 minutes for a response before repeating the dose of nitroglycerin.

Used only for patients showing signs of airway obstruction or wheezing due to allergic reactions.

Used for patients experiencing severe allergic reactions or anaphylaxis.

Should not be given to patients with hypertension, hypothermia, or myocardial infarction.

Hold the EpiPen at a 90-degree angle to the outer thigh and inject.

A medication used to reverse opioid overdoses, commonly given intranasally.

Confirm medication, attach atomizer, administer dose into each nostril.

Drugs like aspirin and clopidogrel that prevent blood clots by making platelets less sticky.

Medicines like warfarin that interfere with blood clotting processes.

Potential issues from intramuscular injections include muscle tissue damage and unreliable absorption.

A method of delivering medication directly into the bloodstream through a vein, providing rapid effect.

Involves injecting medication directly into the bone to access the bloodstream via bone marrow.

Medications absorbed quickly through the lungs are inhaled, reducing effects on other tissues.

Medications placed under the tongue for quick absorption into the bloodstream, faster than oral ingestion.

Liquid medication is aerosolized and delivered into the nostrils for rapid absorption through the nasal mucosa.

A device that delivers a specific dose of medication through the mouth into the lungs, often used for asthma.

Factors like tissue perfusion affect medication absorption via different routes like IM or IV.
