Answer: The Auerbach plexus or myenteric plexus.
Explanation: The muscularis externa is a composed layer of muscles, located throughout the gastrointestinal tract. It has an inner circular muscular layer and a longitudinal external muscular layer. Between the two layers there is a part of the nervous system called Myenteric plexus.
A plexus is like a web of axons (nervous tissue) that provides a specific function. In this case, the myenteric plexus has a main function: motility. All the digestive tract (esophagus, stomach and intestine) possess this structure, to give motility or “peristalsis”, so the food could travel all the way from the esophagus through the colon.

Answer:
The blood pumped by the heart is transported to different parts of the body to deliver oxygen.
Explanation:
Homeostasis is a process whereby living cells maintain a stable internal environment despite changes in their external environment. One way cells perform homeostasis is by ensuring oxygen gas, which is required for cellular respiration, reaches all the cells. However, the circulatory and respiratory systems work hand in hand to fulfill this.
The respiratory system brings in oxygen present in air, which is then carried by a pigment in the blood called haemoglobin, to every part of the body. Hence, respiratory system brings in the oxygen gas while circulatory system ensures the oxygen gas is everywhere in the body.
