Homeostasis and Body Systems Regents Mini-Review

When an individual goes without eating for a day, his or her blood sugar level remains about the same throughout the day. This relatively constant condition is maintained by

• homeostatic control

• egestion

• reproduction

• growth of cells

Which statement accurately compares cells in the human circulatory system to cells in the human nervous system?

• Cells in the circulatory system carry out the same life function for the organism as cells in the nervous system.

• Cells in the circulatory system are identical in structure to cells in the nervous system.

• Cells in the nervous system are different in structure from cells in the circulatory system, and they carry out different specialized functions.

• Cells in the nervous system act independently, but cells in the circulatory system function together.

Bumblebees show some ability to control their own body temperature. During cold weather, bumblebees have been observed warming their flight muscles by shivering. The bees are able to maintain a body temperature several degrees above that of the surrounding air. Regulation of their internal body temperature is an example of

• diffusion

• synthesis

• respiration

• homeostasis

Which process is most directly responsible for maintaining internal stability in an organism when its environment is constantly changing?

• digestion

• feedback

• reproduction

• evolution

What usually results when an organism fails to maintain homeostasis?

• Growth rates within organs become equal.

• The organism becomes ill or may die.

• A constant sugar supply for the cells is produced.

• The water balance in the tissues of the organism stabilizes.

The main function of the human digestive system is to

• rid the body of cellular waste materials

• process organic molecules so they can enter cells

• break down glucose in order to release energy

• change amino acids into proteins and carbohydrates

Feedback interactions in the human body are important because they

• determine the diversity necessary for evolution to occur

• direct the synthesis of altered genes that are passed on to every cell in the body

• regulate the shape of molecules involved in cellular communication

• keep the internal body environment within its normal range

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

Which situation indicates that a disruption of homeostasis has taken place?

• the presence of hormones that keep the blood sugar level steady

• the maintenance of a constant body temperature

• cell division that is involved in normal growth

• a rapid rise in the number of red blood cells

In humans, the maintenance of a stable internal temperature is a direct result of

• detection of and reaction to stimuli in the environment

• digestion of starches and absorption of protein from the internal environment

• diffusion of water and excretion of glucose to the external environment

• transport of ATP and locomotion through the environment
