Systems in the Human Body

Question

Systems in the Human Body
The human body is made up of different systems that interact with each other to achieve homeostasis for the body. All of the organ systems are made up of organs that are made from tissues and cells. The cells that form the tissues of an organ depend on the function of the organ. Three of the body’s systems—the circulatory, digestive, and excretory system—are shown.

The Circulatory system is made up of the heart, veins and arteries. It pumps blood to the rest of the body. The Excretory system is made up of the kidneys, ureter, bladder, and urethra. It takes waste and removes it from the body. It also filters toxins from the blood and removes excess waste from the body. The Digestive system is made up of the esophagus, liver, stomach, large intestine, and small intestine. It works when food and water enter through the mouth. It breaks down the food and absorbs the nutrients. Then it removes the solid waste.

Multiple Choice Question
Which statement BEST describes an interaction between the circulatory system and the digestive system?

A.
The circulatory system transports hormones that signal the digestive system to excrete urine from the body.

B.
The digestive system absorbs nutrients from food, and the circulatory system processes the waste from the food.

C.
The digestive system absorbs nutrients from food, and the circulatory system carries the nutrients throughout the body.

D.
The circulatory system transports oxygen throughout the body, and the digestive system removes carbon dioxide from the body.

Answer 1

The statement that BEST describes an interaction between the circulatory system and the digestive system is:

C. The digestive system absorbs nutrients from food, and the circulatory system carries the nutrients throughout the body.

This accurately reflects the relationship where the digestive system breaks down food and absorbs nutrients, which are then transported by the circulatory system to various parts of the body for use.
