Which of these is an example of physiology? The liver produces many of the blood proteins. The surface of the brain is highly folded. Skin consists of two kinds of tissue. Tendons are composed of collagen fibers. - Correct Ans:✔✔ The liver produces many of the blood proteins Fig 1.1 - Correct Ans:✔✔ z A microscopic image shows many cube-shaped cells forming a tube or duct. What level of structural organization is this? organ level tissue level cellular level
chemical level - Correct Ans:✔✔ tissue level What organ system is responsible for breaking down food into molecules that can be absorbed by the body? respiratory system integumentary system circulatory system digestive system - Correct Ans:✔✔ digestive system Which of these is an organ of the urinary system? uterus prostate gland rectum kidney - Correct Ans:✔✔ Kidney Physical trauma to a body organ is known as blunt trauma. Which organs of the body account for 75 percent of all blunt trauma injuries? pelvic cavity organs abdominal cavity organs thoracic cavity organs cranial cavity organs - Correct Ans:✔✔ abdominal cavity organs
Functions For Life - Correct Ans:✔✔ Responsiveness: the ability to sense changes in the environment and react to them Movement: includes all the activities promoted by the muscular system Maintaining boundaries: keeping one's "inside" distinct from the "outside" Digestion: breaking food down into smaller pieces Excretion: removing wastes from the body Growth: increasing in size Reproduction: producing offspring Metabolism: all chemical reactions that occur in body cells Fig 1.3 - Correct Ans:✔✔ Which of these is an example of maintaining boundaries?
The nerve endings in the skin keep us aware of the external environment. Calcium deposits make bones hard. The cell membrane controls the movement of substances into or out of the cell. The cells in the retina of the eye absorb light. - Correct Ans:✔✔ The cell membrane controls the movement of substances into or out of the cell In addition to oxygen and nutrients, what other substance must be taken into the body in order to survive? carbon dioxide pigments hormones water - Correct Ans:✔✔ water The skin prevents the loss of body fluids from evaporation. Which function necessary for life does this describe? metabolism excretion
Stimulus: produces a change in variable Effector: provides the means for the control center's response to the stimulus Input: sensory information sent to the control center Control center: determines the level at which a variable is to be maintained and analyzes the input to determine the appropriate output Response: effector feeds back to reduce the effect of the stimulus and returns the variable to homeostatic level Hemostasis is the process by which bleeding is stopped by the body. This process involves clot formation. Which of the following statements describes feedback regulation during clot formation? Select the correct answer. During blood clotting, the original stimulus is increased by positive feedback. During blood clotting, the original stimulus is decreased by positive feedback.
During blood clotting, the original stimulus is decreased by negative feedback. During blood clotting, the original stimulus is increased by negative feedback. - Correct Ans:✔✔ During blood clotting, the original stimulus is increased by positive feedback. Which of these carries out the commands of a homeostatic control center? nerve stimulus receptor effector - Correct Ans:✔✔ effector Which of these describes the effect of a negative feedback mechanism? pushes the variable farther away from the set point reduces the intensity of the initial stimulus extends the duration of the initial stimulus
changes the set point of a variable increases the effect of the initial stimulus reduces or stops the initial stimulus initiates a stimulus - Correct Ans:✔✔ reduces or stops the initial stimulus Which of the following cavities is NOT associated with the urinary bladder? abdominal cavity pelvic cavity ventral body cavity abdominopelvic cavity - Correct Ans:✔✔ abdominal cavity Which of these body parts is distal to the crural region? carpal region gluteal region acromial region tarsal region - Correct Ans:✔✔ tarsal region
What cavity is superior to the diaphragm? pelvic cavity abdominal thoracic spinal cavity - Correct Ans:✔✔ thoracic In what quadrant is the gallbladder located? right hypochondriac region umbilical region left upper quadrant right upper quadrant - Correct Ans:✔✔ right upper quadrant Which of the following is visible when viewing the front of a human body in anatomical position? popliteal region olecranal region patellar region occipital region - Correct Ans:✔✔ patellar region
palms toward the back palms toward the front palms toward the feet palms toward the body - Correct Ans:✔✔ palms toward the front fig 1.5 - Correct Ans:✔✔ fig 1.7 - Correct Ans:✔✔ fig 1.6 - Correct Ans:✔✔
