Homeostasis and the Human Body Review

What is the function of the nervous system?

• to control and coordinate body functions and systems.

• to protect the body from harm.

• to identify pain and begin healing.

• to break down food.

What is the main function of the endocrine system?

• It creates chemicals, or hormones, that are sent around the body to maintain homeostasis.

• It creates electrical messages that are sent around the body to maintain homeostasis.

• It maintains the correct level of oxygen in the body to maintain homeostasis.

• It releases waste from the body to maintain homeostasis.

What is the main function of the excretory system?

• to collect and eliminate waste products from the body

• to strengthen skeletal muscles

• to separate nutrients and waste from the food

• to bring oxygen to body cells and eliminate carbon dioxide

In an external environment that is always changing, an organism must be able to maintain relatively constant internal conditions. This maintenance of a stable internal environment is known as

• transport

• homeostasis

• metabolism

• nutrition

During periods of high activity, which of the following is produced if there is not enough oxygen available?

• Glucose

• Oxygen

• Carbon Dioxide

• Lactic Acid

From the smallest functional units to the largest, the body is organized as follows: 

• cell, organelle, system, organ, tissue, body. 

• organ, cell, tissue, system, body, organelle

• system, organ, tissue, cell, organelle, body. 

• organelle, cell, tissue, organ, system, body.
