70 year old Lydia with virus infected lungs
PHYSIOLOGY
Mrs Lydia might have had an abnormal pumping of blood in the heart. Probably the pulmonary semi-lunar valves might have been faulty; and because of this, oxygenated blood was sent back to the lungs. This could cause Pneumonia( pulmonary edema
Her cardiovascular system will be greatly affected because she's not able to in oxygen to her lungs(stopping pulmonary circulation, systemic circulation and also circulation of blood around the heart)
Due to the poor function of her lymphocytes( B and T cells, macrophages and natural cell killer, interferon etc), there will be a replication of the virus in the cell of the body.
The fluid in the lungs will prevent air from entering the lungs, thereby limiting the function or role of surfactant in the lungs. Without surfactant, the lungs will collapse.
Slow intake of oxygen will definitely slow down her ventilation, thereby preventing the alveoli to trap more air
BOYLES LAW: Increase in volume will lead to an decrease in pressure and vice versa. If pressure is greater in the lungs than outside the lungs, then air rushes out ( air rushes in when the statement is flipped).
Alveoli ducts are airways that branch of respiratory bronchioles. Multiple of alveoliar is called alveolar duct.
Bronchi large airways of bronchial tree. Consist of pseudostratified columnar epithelium.
Bronchioles are smaller conducting airways of bronchial tree. Made of simple ciliated columnar epithelium.
Respiratory Physiology at Alveoli: Microscopic sac that encourages gas exchange
Inflammatory response by lymphocytes in the respiratory system could lead to tissue damage.
It is also a major component of the lung disease like: asthma, COPD, lung cancer.
In high altitude, Hypoxia ventilation induces ventilation. Therefore oxygen partial pressure is reduced.
Hpoxia ventilation is the process where by ventilation(active breathing) is due to hypoxia (lack of oxygen).
DALTON LAW: The air in the atmosphere is a mixture of many different gases, that vary in concentration. Dalton’s law states that at any given time, the percentage of each of these gasses in the air we breathe makes its contribution to total atmospheric pressure, and this contribution will depend on how much of each gas is in the air we breathe.
Alveoli ducts Promotes gas exchange in the lungs
Bronchi: Bronchi conducts air
PHYSIOLOGY: Bronchioles conducts air, smooth muscles in walls allow bronchoconstriction and bronchodilation
ANATOMY
Virus Infection could weaken the B and T lymphocytes of the lung.
In Mrs Lydia's case, law of Dalton is not followed.
Mrs Lydia partial( oxygen will be low) pressure are unbalance due to the change in altitude from Forth worth to Denver
Denver unlike Fort worth is a high altitude with 5,280 feet above sea level. With such altitude, the body begins to experience low oxygen, and decrease air pressure.
Due to her old age, the thymus will not be very effective to mature the T cells of the body; specifically her lungs. In order words, Mrs Lydia will be susceptible to all kinds of diseases and viral infection
