The website has the complete lesson note for all the subjects in secondary school but this piece showcases the SS1 Animal Husbandry Lesson Note on Respiratory System of Animals. You can use the website search button to filter out the subject of interest to you.
TOPIC: RESPRIRATORY SYSTEM
Respiratory system includes all the organs and tissues associated with the exchange of gases between the animal and its environment leading to the release of energy.
Sub Topic 1
TYPES OF RESPIRATION
- Aerobic respiration
- Anaerobic respiration
This is a form of respiration which takes place in the presence of oxygen.
C6H12O6 6O2 → 6C02 + 6H20 + Energy
Glucose oxygen carbondioxide water
This is a form of respiration which takes place in the absence of oxygen. When glucose is broken down, it releases lactic acid and energy in animals, but in the plant, the end product of anaerobic respiration are alcohol, carbondioxide and energy.
C6H12O6 → 2C2H5OH + 2CO2 + Energy
Glucose alcohol carbondioxide
Sub Topic 2
During breathing, air flows from the nostrils to the pharynx to the larynx and to the lungs. This breathing activity leads to the movement of the rib cage known as the process of breathing. This involves:
- Inspiration/inhalation/breathing in
- Expiration/exhalation/breathing out.
