Unit 1 Pulmonary Anatomy & Physiology

What are the primary inspiratory muscles?

• Diaphragm, Scalenes & Intercostals

• Abdominals & SCM

• Diaphragm & Phrenic Nerve

• Deltoids & Upper Traps

What are the Primary Expiratory muscles?

• NO MUSCLES REQUIRED DURING QUIET EXHAL.
• Abdominals, intercostals

  Pect Major

• Active movement

• Diaphragm & intercostals

What membrane covers the lungs?

• Synovial Fluid

• Pleurae

• Hilum

• Chest Wall

What are the lungs specific functional cells. Porous spongy tissue

• Oxygen

• Hemoglobin

• Hila

• Parenchyma

What is pulmonary circulation?

• Pulmonary circulation happens in the lungs

• Delivers nutrient rich blood supply to the lungs themselves.

• The circulatory system that involves deoxygenated blood going to the lungs (alveoli) and returning oxygenated blood from lungs.

• The circulatory system that involves oxygenated blood going to the lungs and returning deoxygenated blood from lungs.

What is respiration?

• General term for gas exchanged in the body

• Chronic Respiratory function

• Term of ventilation

• Ability to respirate

What is Ventilation?

• The movement of air in alveoli

• Opening in the trachea

• Elasticity in the lungs

• The movement of air in/out of the lungs

Where does gas exchange occur during respiration?

• Trachea

• Bronchi

• Alveoli

• Surfactant

What are the chest wall motions?

• Intrapulmonary

  Intrapleural

This occurs when areas of the lung receive normal blood flow but no ventilation, causing more deoxygenated blood than usual to return to the heart. About 3% is considered normal.
