The gastrointestinal wall is composed of four layers or tunics:
- Mucosa
- Submucosa
- Muscularis mucosa
- Serosa
The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.
The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.

Answer:
The majority of living things are made up of various types of cells that are each specialized to execute a specific purpose. Because certain enzymes, also known as proteins, play a big role in biochemical function, distinct sets of genes must be turned on and off in different cell types. This is how cells differ from one another.
Answer:
Change in the vascular system.
Explanation:
High blood pressure occurs when the arteries in the human body system become rigid thereby making the blood pressure rise.
The cause for this situation particularly in older people is the changes in the vascular system or circulatory system.
This is said to be vasoconstriction which lowers the flow of blood in the circulatory system, thereby causing high blood pressure
Hence, since Mr. Ackah is a retired teacher, it is believed that he is an old man susceptible to changes in the vascular system or vasoconstriction.
Amino acids combine to make proteins.
