2. 1. Organisms strive to keep their internal conditions nearly constant
1. Organisms strive to keep their internal conditions nearly constant. The body systems work together to maintain this overall equilibrium known as
regularity
homeostasis
body control
system alignment

3. You need to send urine out of your body. Which systems are involved?
Nervous and endocrine systems
Muscular and digestive systems
Excretory and muscular systems
Endocrine and excretory systems

4. 3. Which system is considered to be the first line of defense as part of your body’s immune system?
reproductive
Skeletal
integumentary
nervous

5. The correct order for the levels of organization from smallest to largest is
Cell, tissue, organ, organ system
Cell, atom, molecule, organ, organ system
Organ system, organ, tissue, cell
Organism, cell, tissue, organ

6. An individual with diabetes militias either does not produce enough insulin or does not respond to it properly. This means that they are unable to maintain homeostasis of their glucose levels. The endocrine system regulates this process by
producing thyroxin in the thyroid gland
the exchange of carbon dioxide and oxygen
Feedback inhibition control of the hormones insulin and glucagon produced by the pancreas
Hydrochloric acid that breaks down carbohydrates in the stomach

7. How do the endocrine and reproductive systems work together?
Ovaries and testis produce essential hormones for sexual development and gamete formation.
The urethra carries both urine and sperm out of the body.
The thymus stimulates T cell development.
Insulin produced by the pancreas maintains glucose levels within the bloodstream.

8. Recognizing and coordinating the body’s response to changes in its internal and external environment is the function of which body system?
digestive
nervous
Immune
muscular

9. The level of water in blood is controlled primarily by the kidneys
The level of water in blood is controlled primarily by the kidneys. The kidneys filter blood and either direct water to be excreted as urine or to be reabsorbed into the blood. These kidney functions are regulated by antidiuretic hormone (ADH). In response to dehydration, the hypothalamus stimulates the pituitary gland to release increased levels of ADH. In response to excess water in the blood, the pituitary releases less ADH. Knowing that water levels in the blood are controlled by feedback inhibition, what events related to kidney function occur when ADH levels decrease?
Kidneys secrete diuretics into the blood
Kidneys produce more urine
Kidneys increase reabsorption of water into the blood
Kidneys produce less urine

10. The endocrine system interacts with many other body systems
The endocrine system interacts with many other body systems. It sends messages that signal organs in various systems to perform actions or to stop performing certain actions. These signals are carried by messengers known as
Performance indicators
hormones
On/off switches
lymphocytes

10. An individual goes to the doctor because they are not feeling well. After some blood work the doctor informs the patient that they have abnormal T cell numbers and that an HIV test should be done. Which body system is being affected?
integumentary system
immune system
reproductive system
circulatory system
