Why blood is necessary for oxygen delivery to all parts ofthe body in large animals
Answers
Answer:
Therefore, blood is necessary for oxygen delivery to all parts of the body in large animals, as well as for a variety of other essential functions that are necessary for life.
Explanation:
Blood is necessary for oxygen delivery to all parts of the body in large animals because it contains red blood cells that carry oxygen from the lungs to the tissues and cells throughout the body. Large animals have a relatively large volume of body tissue that requires oxygen to function, and therefore, they need a large volume of oxygen-carrying blood to meet this demand.
The process by which oxygen is delivered to the tissues and cells of the body is called respiration. In the lungs, oxygen diffuses into the bloodstream and binds to hemoglobin molecules in red blood cells. The oxygen-rich blood is then pumped by the heart to the tissues and cells of the body, where it is needed for cellular respiration.
In addition to oxygen, blood also carries nutrients, hormones, and waste products, and helps regulate body temperature and pH. Without an adequate supply of blood, large animals would not be able to meet the metabolic demands of their body tissues, leading to cellular dysfunction and ultimately death.
Therefore, blood is necessary for oxygen delivery to all parts of the body in large animals, as well as for a variety of other essential functions that are necessary for life.
