Unit 1 Pulmonary Anatomy & Physiology

What are the primary inspiratory muscles?

• Diaphragm & 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 and returning oxygenated blood from lungs.

• There is not pulmonary circulation in the body

What is respiration?

• General term for gas exchanged in the body

• Chronic Respiratory function

• Term of ventilation

• Ability to respirate
