Unit 11: Body Systems Review KEY
Epithelial
Muscular
Urinary Bladder
Connective
Kidneys
Insulin
Homeostasis
Integumentary System
Excretory System
Integumentary System
The level of water in the blood is decreasing
Nervous
White
Circulatory System
Flattening and moving down
Less urine is produced to prevent dehydration
1. The four tissue types are: Epithelial, muscular, connective, and nervous.
2. This organ is responsible for maintaining homeostasis by filtering cellular wastes from the blood
kidneys
3. This structure in the excretory system is responsible for storing filtered wastes is the urinary bladder
4. White blood cells ingest pathogens and also dead and cellular debris.
5. The Integumentary system functions as the body’s first line of defense.
6. An example of how the excretory and nervous system
work together is less urine is produced to prevent
dehydration
7. The diaphragm moves to increase the volume of the
thoracic cavity during breathing by flattening and moving
down
8. When blood sugar levels are high, the pancreas produces
insulin
9. When you sweat during exercise, your body is trying to
maintain a constant internal body temperature or homeostasis
10. Excretory system Integumentary system and circulatory systems work together to maintain body
temperature when you sweat.
11. ADH (Antidiuretic Hormone) controls the rate that water is removed from your blood. The
hypothalamus releases a signal to the pituitary gland that causes ADH to be released into the blood
stream of kidneys. The level of water in the blood is decreasing causes a release of ADH and the
slowing of kidney activity.

b. Patients were closely monitored by
medical personnel.
Use the following word bank to answer questions 13- 19
Interact and depend on each other to function properly
Sperm
Ligaments
Male hormones
Alveoli
Secrete hormones directly to the bloodstream
Pituitary
Thyroid
Lungs
WBC to promote healing by removing pathogens Trachea
Hypothalamus
13. A function of the endocrine system is to secrete hormones directly into the bloodstream
14. The function of the thyroid demonstrates that organ systems interact and depend on each other to
function properly
15. Regulation among these three glands help to maintain homeostasis
a. Thyroid
b. Pituitary
c. Hypothalamus
16. The role of the circulatory system in response to infection is to allow blood flow to the infected site
allowing white blood cells to promote healing by removing pathogens
17. What type of connective tissue attaches muscles to bones? Tendons
18. What three structures are parts of the respiratory system? Lungs_, Trachea, and Alveoli
19. The testes produce sperm and male hormones.
20. Describe how oxygenated blood leaves the heart
through the blood vessels and then back to the heart.
Oxygenated blood travels through the
arteries to the arterioles then to the
Capillaries where gas exchange takes
place. The now deoxygenated blood
then travels through the venules to
the veins back to the heart.
