b) External intercostal muscles, neck muscles and abdominal muscles
c) Diaphragm, external intercostal muscles and neck muscles.

Answer 7

C. Diaphragm, external intercostal muscles and neck muscles

Question 8

What muscles facilitate inspiration

Answer 8

Diaphragm,external intercostal muscles and neck muscles

Question 9

Muscles that aid in forced expiration
a) Internal intercostal muscles, and abdominal muscles
b) Abdominal muscles and diaphragm
c) Internal intercostal muscles and external intercostal muscles
d) Internal intercostal muscles and diaphragm.

Answer 9

A,Internal intercostal muscles and abdominal muscles

Question 10

What muscles aid forced expiration

Answer 10

Internal intercostal muscles and abdominal muscles

Question 11

The following is the correct sequence of events for a successful inspiration:
a) Diaphragm & external intercostal muscles contract; drop in intrapulmonary
pressure; size of thoracic cavity increases; flow of air into lungs
b) Diaphragm & external intercostal muscles contract; size of thoracic cavity
increases; drop in intrapulmonary pressure; flow of air into lungs
c) Diaphragm & external intercostal muscles contract; size of thoracic cavity
increases; drop in intrapulmonary pressure; flow of air out of lungs
d) None of the above

Answer 11

B.Diaphragm and External intercoastal muscles contract:thoraic cavity increases and drop in intrapulmonary pressure and air flows in lungs

Question 12

Sequence of successful inspiration

Answer 12

Diaphragm & external intercostal muscles contract, drop in intrapulmonary pr3ssure , size of thoracic cavity increased and air flows into lungs
