A person's pulse rate generally goes down while sleeping. One reason for this decrease is

• the body is producing more carbon dioxide when a person is sleeping

• a person is not using energy while sleeping

• a person requires less oxygen when sleeping

• the body is using more nutrients while asleep

The kidney is an organ that collects wastes and excess water from the blood and sends them to the bladder where they are stored before being removed from the body. Which two systems work together to perform this function?

• immune and respiratory

• circulatory and excretory

• skeletal and nervous

• digestive and circulatory

A group of students obtained the following data while trying to determine the effect of EXERCISE on pulse rate. Which two body systems were most actively involved in this experiment?

• respiratory and immune

• digestive and endocrine

• respiratory and circulatory

• immune and circulatory

When people exercise, their body cells build up more waste quickly. Which two body systems work together to remove these wastes from their cells?

• immune and endocrine

• digestive and skeletal

• respiratory and circulatory

• circulatory and digestive

What is an advantage of a change in pulse rate after exercising?

• The heart needs to produce more energy to supply the active muscle cells and maintain homeostasis.

• An increased blood flow carries excess waste products away from the active muscle cells.

• The blood is removing oxygen from muscle cells that were not active and carrying it to muscle cells that are active.

• The blood is supplying the active muscle cells with carbon dioxide to neutralize wastes in those cells.
