Clinical Scenario - Digestive system
You are working in a midwifery setting and have been asked to design a Poster to inform pregnant patients about eating, nutrition and constipation.
Answer:
Introduction:
Overview of digestive system
Structure:
Stomach:
Digestion process:
The process starts with ingestion which means eating.
Next step is propulsion that includes transport of the food to the
digestive tract. In this process peristalsis is include that processed
the food by the contraction and relaxation of smooth muscles of the
walls of digestive tract and creates force to move the food in the
digestive tract.
Mechanical digestion is the next step in which food breaks down into
smaller particles in order to facilitate the digestion process. It
begins in the mouth with chewing, then continues in the stomach and
further break down occurs in the small intestine. A similar process like
peristalsis occur here that is known as segmentation.
Chemical digestion is the process of breaking down the food with the
help of digestive enzymes.
Then absorption of nutrients occur with the help of jejunum and ileum
and the absorbed nutrients transport to the bloodstream in order to
deliver nutrients throughout the body.
Defecation is the last step that includes processing of waste materials
and elimination (Rizzo 2015).
Correlation of digestive system and cardiovascular system:
In order to proceed with effective digestion process the
cardiovascular system correlates with the digestive system in an
effective manner.
It is important for the human body to transport adequate nutrients to
each cell of the body in order to function properly. In this process the
digestive system break the food into smaller particles absorb nutrients
from them and transport the nutrients to the blood.
On the other hand, the alimentary canal absorb the nutrients and
cardiovascular system helps to distribute the nutrients throughout the
body.
The digestive system functions to absorb iron from the food that is
required for the synthesis if haemoglobin and in order to maintain the
volume of plasma, it transfers water to the blood vessels. Such process
helps the cardiovascular system to function properly.
In order to facilitate the digestion process it is important to
transport oxygen throughout the body and remove CO2 and other waste
material from the body. In this regards, the cardiovascular system helps
to facilitate the transport of blood in order to provide oxygen
throughout the body and remove CO2 and other waste materials from the
body through respiration and sweating.
In addition the cardiovascular system receives some signal from the
endocrine gland and send it to digestive system in order to control the
speed of digestion (Sherwood, L., 2015).
