Answer:
The many roles of blood include delivering nutrients and oxygen to cells, Homeostatic is the ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium. It relaxes the blood vessels and capillaries which may help with gas exchange.
Explanation:
The question asked to fill in the gap with the right words .
Generally, the short essay talks about the function of the blood in the body.
Homeostasis is the tendency of the body to maintain a stable condition within the limit it can survive. Homeostasis is a self regulating property of the cell, tissues and organisms that allows the maintenance and regulation of the body to function properly. Usually the organism adjust it internal environment to maintain a stable equilibrium.
Blood is usually pumped from the right side of the heart to the blood vessel of the lungs .When blood enters the pulmonary capillaries , new oxygen enters the blood and carbon-dioxide is removed. This process is what is called gas exchange.
Single-celled organisms exchange gases directly across their cell membrane. However, the slow diffusion rate of oxygen relative to carbon dioxide limits the size of single-celled organisms. Simple animals that lack specialized exchange surfaces have flattened, tubular, or thin shaped body plans, which are the most efficient for gas exchange. However, these simple animals are rather small in size.
