1. (a) The diagram
(of a mannel:
presents the Respiratory Sveten
The purpose of this system is to enable the
body to take in oxygen for tissue respiration
furthermore to give out carbon dioxide and water vapour which are wants products resulting from tissue respiration,
A. Trachea..
B. Bronchus
D.” Alveoli. E. Larynx
G. Lung
H. Diaphrag
Bronchiole Pleura
In» (alveoli) gaseous exchange takes place where oxygen in diffused into the blood of blood capillaries and carbon dioxide is diffused out from the blood,
(e) These organs are found in the thoracic cavity
of the mammalian body.
(a) Respiration is the process involved in all living organisms during which energy is se free. It usually consists of the breaking down of complex carbon compounds together. with oxidation. It then results in the giving off carbon dioxide and water as waste products and the liberation of energy.
Respiration occurs in two wayss
(i) Aerobic respiration the living
organisms respire in the presence of fres oxygen. They take in oxygen from air or water with the liberation of energy by oxidation of foods,
(ii) inaerobic respiration - the living
organisma respire in the absence of free. oxygen. They take in no oxygen with the liberation of energy, by enzymatic reaction of the complex molecules of the intake food.
It is known that aerobic respiration has 100 times more powerful than that of amsarabic respiration.
Oxygen in the atmospheric air is innala int the body through the nose or the mouth. It' passes through the trachea, the bronchi and Gaseous exchange bronchioles in the lungs. takes place in the alveoli where oxygen is diffused into the capillaries and combines with haemoglobin in the red corpuscles. Blood with oxy-haemoglobin is carried to through the pulmonary vein to the left auricle than to the left ventricle. This blood is pumped out through the aorta and 18 redistributed by means of the various arteries to all living tissuse of the body for combustion.
