Executive summary
There are several organ systems in the human body that control the different
physiological processes and metabolism inside the cells. While the circulatory system is
involved in distribution of oxygen through the bloodstream and the respiratory system
helps in exchange of gases, the immune and endocrine system protects the body
against infection and chemically coordinates the action of hormones respectively. The
digestive system on the other hand is involved in providing nutrition and the nervous
system controls all other organs. This report aims to address questions related to 3
case scenarios that encompass separate physiological disorders.

Case study 1
Answer 1
The various structures of the cardiovascular system are given below-
 The Heart
The heart walls are made up of 3 layers, the epicardium, myocardium and the
endocardium.
 The blood vessels- the arteries, veins and capillaries (Miller, 2013).
Answer 2
The major functions of the circulatory system are as follows-
 It helps in circulating oxygenated blood to all parts of the body.
 It brings deoxygenated blood from all body cells and brings them to the lungs for
purification.
 It facilitates transport of nutrients and water to the cells and tissues.
 It expels waste materials such as, carbon dioxide and nitrogenous wastes away
from the cells (Binnington & Obenchain, 2013).
 It helps in maintaining a constant body temperature.
 The white blood cells and antibodies present in blood also provide protection
against several diseases thereby, providing resistance.
Answer 3
The respiratory system consists of the following structures-
Upper respiratory tract- This part of the respiratory system includes the nose, the
mouth, and the portion of the trachea that helps in taking in and giving out air.
Lower respiratory tract- This includes the trachea, the bronchi, the lungs and the
broncheoli. This part of the respiratory system involves the act of breathing. These
organs are present in the thoracic cavity and are protected by means of a ribcage, the
sternum (breast bone) and by muscles that are present between the diaphragm and the
ribs.
Answer 4
The cardiovascular and the respiratory system interact in a complex manner to
perform several physiological functions. These systems help in delivering oxygen to the
tissues and expelling carbon dioxide out of the tissues. The respiratory system supplies
oxygen to the blood to form oxyhemoglobin and removes carbon dioxide from the
bloodstream. The deoxygenated blood that is rich in carbon dioxide and has low oxygen
content is pumped to the lungs through the pulmonary arteries (Chapman, Douglas &
Siva-Jothy, 2013). On expansion, the lungs receive air from the external environment,
