  1. Digestive system: controls movement of feces (unused material from food digestion)
  2. Urinary system: kidney filters blood for nitrogen containing wastes which leave body through the urine
  3. Respiratory system: expels Carbon dioxide waste as air is breathed out. Match the following systems to their functions.
  4. ______________ : Delivers oxygen and nutrients to the tissues.
  5. _____________ : Controls the body with chemical molecules called hormones.
  6. _____________ : Produces antibodies that attach to foreign substances.
  7. _____________ : Removes and filters excess fluid from tissues. Word Bank: Immune, Lymphatic, Cardiovascular, Endocrine - Correct Ans:✔✔ 1. Cardiovascular System

  1. ___________ : Arteries, veins, heart.
  2. __________ : Trachea, bronchi, alveoli.
  3. __________ : Adrenal glands, pancreas, pituitary.
  4. __________ : Esophagus, large intestine, rectum.
  5. __________ : Kidneys, bladder, ureters. Word Bank: Respiratory, Cardiovascular, Endocrine, Urinary, Digestive - Correct Ans:✔✔ 1. Cardiovascular System
  6. Respiratory System
  7. Endocrine System
  8. Digestive System
  9. Urinary System Which organ system contains the: spleen, lymph nodes, lymph vessels and the thymus gland? A. lymphatic / immune system B. endocrine system C. respiratory system

D. integumentary system E. lymphatic immune system - Correct Ans:✔✔ Endocrine (b) Which organ system contains the spleen? A. Digestive system B. Circulatory system C. Integumentary system D. Lymphatic / Immune system E. Endocrine system F. Reproductive system G. Respiratory system - Correct Ans:✔✔ Lymphatic/Immune System (d) The spleen contain immune cells (white blood cells) that destroy any bacteria/viruses in blood as it filters through. The pancreas is found in 2 different organ systems, Which 2? A. Digestive system and Immune system B. Circulatory system and Lymphatic system C. Integumentary system and Endocrine system D. Endocrine system and digestive system

E. Integumentary system and Digestive system - Correct Ans:✔✔ Endocrine systems and Digestive System (d)

  • Endocrine System: The pancreas produces hormones, such as insulin.
  • Digestive System: The pancreas produces digestive enzymes to break down food in the intestines. Functions of the urinary system include: kidneys filter blood to:

A. remove carbon dioxide from blood and any other toxins (all to be secreted into urine) B. maintain water levels (increase urine production) and remove Carbon dioxide C. remove waste products (urea) and produce hormones such as insulin D. remove waste products (ex: urea) and maintain blood pressure by regulating water content of blood - Correct Ans:✔✔ Remove waste products (ex: urea) and maintain blood pressure by regulating water content of blood (d)

Which is not matched correctly? (organ system with excretion type) A. digestive system / feces B. respiratory system / carbon dioxide C. urinary system / nitrogen wastes D. all are matched correctly E. endocrine system / hormones - Correct Ans:✔✔ Endocrine system / hormones (e)

  • Hormones are produced by the endocrine system, but they are NOT considered a "waste" product.
  • Excretions are end products that are NOT needed by the body and are removed.
  • Hormones are produced on purpose and are needed to regulate the body. In chapter 1, the word "contractility" is discussed in regard to ________________. (one of the requirements of life) A. excretion B. movement

C. growth D. metabolism E. responsiveness - Correct Ans:✔✔ Movement (b)

  • Contractility is the muscle cell's ability to move by shortening in length which allows movement of a body part. Responsiveness is a requirement of life. Which organ system is most involved with this requirement? A. endocrine system B. respiratory system C. lymphatic/immune system D. digestive system E. nervous system - Correct Ans:✔✔ Nervous System (e) Which statement regarding metabolism is true? (as stated in our book) A. the process of breaking down substances into simpler building blocks is known as anabolism (one of the 2 divisions of metabolism)

B. a relatively stable internal environment, within limits C. a dynamic state within an unlimited range, depending on circumstances D. the lowest possible energy usage - Correct Ans:✔✔ A relatively stable internal environment, within limits (b) The majority of chemical reactions in the human body are controlled by ______________ feedback. A. entropic type feedback B. positive C. half are positively controlled, half are negatively controlled D. negative - Correct Ans:✔✔ Negative (d) With regards to a set point or normal limit, negative feedback always __________ a physiological value to the set point or normal limit. A. There is not enough information to answer this question. B. decreases C. increases

D. returns - Correct Ans:✔✔ Returns (d)

  • Regardless of the direction of the initial disturbance, returning to the original set point or normal limit is negative feedback. Referring to control methods of homeostasis, ____________ feedback occurs when the output (product) increases or enhances the original stimulus. A. positive B. negative C. long standing D. variable - Correct Ans:✔✔ Positive (a)
  • Referring to control methods of homeostasis, positive feedback occurs when the output (product) increases or enhances the original stimulus. Examples: blood clotting, labor contractions, milk production for nursing babies Which of the following is an example of a positive feedback?

B. iron C. zinc D. oxygen E. calcium - Correct Ans:✔✔ Zinc (c) Which is the correct symbol for sodium? A. Sm B. Na C. So D. Nm E. S - Correct Ans:✔✔ Na - (b) Which is the correct symbol for iron? A. I B. Ir C. In D. Fe E. none of the above - Correct Ans:✔✔ Fe - (d) What is the chemical symbol for Potassium? - Correct Ans:✔✔ K

What is the chemical symbol for Calcium? - Correct Ans:✔✔ Ca What is the chemical symbol for Chlorine? - Correct Ans:✔✔ Cl The chemical symbol: "Cu" stands for ________. - Correct Ans:✔✔ Copper A charged particle is generally called an ion or electrolyte. (T/F) - Correct Ans:✔✔ True What is the correct range or scale for pH? - Correct Ans:✔✔ 0 - 14

  • the lower the number, the more acidic the pH, the higher the number, the more basic (or alkaline) Which number of the pH scale is alkaline (basic)? A. 1 B. 4 C. 7 D. 9

E. within intestinal tract - Correct Ans:✔✔ Intracellular (within the cells) - (d)

  • The majority of water is found within the cytoplasm of cells. Where do you find "interstitial fluid" in the human body?

A. endocrine system B. cardiovascular system C. integumentary system D. respiratory system E. urinary system - Correct Ans:✔✔ Cardiovascular System (b)

  1. After you drink water, it moves from mouth to stomach to intestines.
  2. Water is then absorbed into blood vessels of the cardiovascular system.
  3. Blood is filtered by kidneys and if there is too much water in the blood, it will then be filtered out of blood and into urine which is then moved to the urinary bladder and then out of the body. All organic compounds contain this element. A. C , which is the symbol for Calcium
