1BIOLOGY ASSIGNMENT
Executive Summary:
This report would discuss some of the major organ systems such as the circulatory
system, nervous system, digestive system and the excretory system and talk about how the
organ systems are dependent upon one another to carry out the normal physiological
functions such as homeostasis. Further, the paper would also discuss the relationship of the
endocrine system in maintaining homeostasis and compare between the endocrine and
nervous system to establish a strong concept about the physiological processes.

3BIOLOGY ASSIGNMENT
Introduction:
The human body comprises of a sum total of ten organ systems that are
interconnected and dependent on one another for the normal physiological functioning of the
human body. For instance, the skeletal system relies upon the nutrients supplied by the
digestive system and the nervous system controls the movement of the muscles. Therefore,
this paper would discuss the important physiological functioning of the major systems of the
human body.
Explanation of the functioning of the Organ Systems:
Cardiovascular system and Digestive System:
“The effect of activity on heart rate and digestion” is critically maintained by the coordinated
functioning of the circulatory system with the digestive system. The circulatory system
comprises of the heart, blood vessels, lymph, blood, lymphatic vessel and glands (Sherwood
2015). The system is responsible for circulating oxygenated blood and transporting nutrients
across various organs of the body. The Lymph is a tissue fluid that forms an essential part of
the circulatory system, which is added to the venous blood through the lymphatic vessels.
The digestive system comprises of the buccal cavity, oesophagus, stomach, small and
large intestines, liver, gall bladder, pancreas and the rectum. The digestive system helps in
digestion by breaking down complex macromolecules of the food particles into simple
molecules that are assimilated in the body to generate energy.
The ingested solid food is broken down into chyme which is equivalent to a fluid like
mixture and the chyme is then introduced to the small intestine. The small intestine comprises
of finger like projections, known as the villi that absorb glucose from the fluid mixture and
