The nurse should teach pursed-lip breathing in a patient with chronic obstructive pulmonary disease. This kind of breathing allows the patient to exhale most of the air trapped in the lungs, as hyperinflation is very evident in COPD. The nurse should instruct the patient to inhale slowly for 3 seconds, purse the lips, contract abdominal muscles, and exhale slowly.
Answer:
the total surface area of a human lung IS 70 TO 75 square meters
Explanation:
Estimates of the total surface area of lungs vary from 50 to 75 square metres (540 to 810 sq ft); although this is often quoted in textbooks and the media being "the size of a tennis court"
Answer:
These 3 receptors are different from each other. They do differ from each other by their location and function.
1. Testosterone receptor : It is an Androgenic receptor
2. Ferrotransferrin receptor : It acts as an element-binding protein which is iron responsive.
3. Fibroblast growth factor : It acts as a growth factor.
Explanation:
1. Testosterone :
Location- Xq 11-12 in the X chromosome.
Function-
- maintains male skeletal integrity by osteoblast and osteocytes.
- maintains female sexual, somatic and behavior.
- develops male sexual characters.
2. Ferrotransferrin :
Location- chromosome 3q21
Function-
- intakes iron in the cell.
- maintains the cellular iron equilibrium.
- post-transcriptional modification.
3. Fibroblast (growth) :
Location- chromosome 4p16.3
Function-
- helps in bone development.
- helps in bone growth maintenance by ossification.
Algae and nitrogen-fixing bacteria are photosynthetic organisms.
Answer:
The codon AUG, commonly known as the start codon, specifies the amino acid methionine. As a result, during protein synthesis, methionine is the first amino acid to dock in the ribosome.
