True or false:
Endocrine secretes hormones into the blood that control growth, metabolism, and stress response
True. The endocrine system is responsible for producing and releasing hormones into the bloodstream, which then travel to various target tissues or organs to control growth, metabolism, and stress response, among other bodily functions.
Read the passage about an athlete.
When an athlete's body temperature begins to climb, blood vessels in the skin dilate. As a result, the athlete's face turns red because warm, oxygenated blood moves to the surface of the skin. This process helps to reduce overall body temperature and prevent overheating.
Which organ system most likely helps to keep an athlete from overheating?
A.
the digestive system
B.
the circulatory system
C.
the respiratory system
D.
the reproductive system
The correct answer is B. the circulatory system. In the given passage, it explains how blood vessels in the skin dilate in response to an increase in body temperature. This allows warm, oxygenated blood to move to the surface of the skin, facilitating heat dissipation and preventing overheating. The circulatory system is responsible for the transportation of blood and plays a crucial role in maintaining body temperature.
Blood consists of many different types of cells. These cells work together to keep a person's blood healthy. Which of the following BEST classifies blood? A. organ B. tissue C. organism D. organ system
The correct answer is B. tissue. Blood is considered a connective tissue because it consists of cells suspended in a liquid matrix called plasma. It is responsible for various functions in the body, including transportation of nutrients, oxygen, and waste products, as well as immune responses and clotting. While blood is essential for the functioning of the entire organism, it is not considered an organ, organism, or organ system itself.
Which of the following is an example of an organ system? A. a human bladder storing waste for removal from the body B. a plant's roots absorbing water and minerals from soil C. the living material that lines the inside of a cheek D. a heart, arteries, and veins all working together
The correct answer is D. a heart, arteries, and veins all working together. An organ system is a group of organs that work together to perform a specific function within an organism. In this case, the heart, arteries, and veins work together as the cardiovascular system to circulate blood throughout the body. Option A refers to an organ (bladder), option B refers to a plant organ (roots), and option C refers to a type of tissue (epithelial tissue lining the cheek), not an organ system.
Which two systems interact most to supply the body with nutrients? A. The endocrine system produces hormones that regulate hunger, and the muscular system assists the body in moving food into the stomach. B. The digestive system breaks down the food to make it available for absorption, and the circulatory system transports the nutrients to parts of the body. C. The nervous system stimulates the appetite, and the excretory system removes waste that was not absorbed by the body. D. The skeletal system absorbs all the nutrients needed for the body, and the integumentary system removes excess liquid from food.
The correct answer is B. The digestive system breaks down the food to make it available for absorption, and the circulatory system transports the nutrients to parts of the body.
In the given options, only option B describes the interaction between two systems that work together to supply the body with nutrients. The digestive system plays a role in breaking down the food through mechanical and chemical processes, making it available for absorption. The circulatory system, specifically the blood vessels, then transport these nutrients to the various parts of the body where they are needed for growth, repair, and energy production.
