Exam 22: Being Organized and Steady

A) its ability to regenerate
B) the matrix formed outside the cells
C) the fibrous tissue which stores glycogen

Show Answer

A) secretion and absorption
B) protection
C) cushioning and insulation
D) supporting
E) storage The different types of connective tissues have widely varied functions. Skin and bone protect the body's organs; adipose tissue or fat cushions certain organs and insulates the body; loose fibrous connective tissue supports the body; and bone and adipose tissue store minerals and fat, respectively.

Show Answer

A) pseudostratified columnar epithelium
B) columnar epithelium
C) stratified epithelium
D) transitional epithelium
E) cuboidal epithelium Skin is composed of multiple layers of squamous epithelium, thus considered stratified. The cells change in composition as they move outward from the deepest layer.

Show Answer

A) the effector causes a response.
B) the sensor sends data to the control center.
C) the control center detects a change in the internal environment.
D) the sensor causes an effector to return conditions to normal.
E) the stimulus sends data to the control center. Within a negative feedback loop, the sensor detects the stimulus and sends a signal to the control center. The control center sends a signal, which then reverses the stimulus.

Show Answer

A) cuboidal epithelium.
B) skeletal muscle.
C) bone.
D) pseudostratified epithelium.
E) squamous epithelium. Cells in epithelial tissue are tightly packed together. The cube shape of the cells classifies them as cuboidal epithelium.

Show Answer

A) fluids would collect within body tissue.
B) oxygen would not reach all the cells of the body.
C) urea would build up in the liver.
D) nutrients would not reach the liver.
E) carbon dioxide would not reach the lungs. The lymphatic system collects fluids from the tissues and returns it to the blood. If it were not functioning properly, fluid would pool in the tissues and swelling would result. The other answers correspond to the functions of other systems.

Show Answer

A) kidneys.
B) intestines.
C) brain.
D) skin.
E) trachea. The likeliest location for cuboidal epithelium in the body is the kidneys. Columnar epithelium is found in the intestines; the brain is composed of nervous tissue; the skin contains squamous epithelium; and pseudostratified epithelium is found in the trachea.

Show Answer

A) mucus cells.
B) areolar cells.
C) apocrine cells.
D) goblet cells.
E) fibroblasts. Secretion is a primary function of epithelial tissue. Common in certain epithelial tissues are goblet cells, or single-celled, mucous-producing glands.

Show Answer

A) digestive - mouth, stomach, intestines
B) lymphatic - thymus, vessels, nodes
C) endocrine - mouth, lungs, pituitary
D) reproductive - ovaries, testes, uterus
E) cardiovascular - heart, blood, blood vessels The endocrine system contains hormone-producing glands such as the pituitary, thyroid, and adrenal glands. The mouth is usually considered part of the digestive system and the lungs are part of the respiratory system.

A) cardiovascular
B) urinary
C) respiratory
D) lymphatic
E) skeletal The urinary system filters blood, removing waste products and producing urine in the process. The urinary system also helps maintain the water balance of the body by producing more or less concentrated urine.

Show Answer

A) covers body surfaces
B) generally one cell layer thick
C) stores energy
D) allows for gas exchange in the lungs
E) contains cube-shaped cells Epithelial tissues cover body surfaces and line cavities; it comes in three variations of shape: squamous, cuboidal, and columnar. Epithelial tissue generally forms one layer of cells, which allows for easy gas exchange and diffusion of materials.

Show Answer

A) reproductive
B) integumentary
C) muscular
D) cardiovascular
E) digestive The reproductive system is the only system in the body in which males and females have different organs. Different sex cells are produced along with different hormones. The male reproductive system must deliver sperm into the female's reproductive tract, and the female's reproductive system must support the development of the embryo, fetus, and newborn.

Show Answer

A) is a disadvantage in areas of the body where tissue undergoes a lot of wear and tear, such as the digestive tract.
B) makes epithelial tissue more likely to become cancerous than other tissues.
C) results in an inability to replace damaged tissue.
D) makes it similar to nervous tissue.
E) makes it an unsuitable tissue type for the outer layer of skin. The ability of epithelial tissue to continually divide is a disadvantage in that it makes these tissues more susceptible to cancer. However, it is an advantage in areas of high wear and tear, such as the lining of the digestive tract and the skin.

Show Answer

A) The body temperature would continue to increase.
B) The body temperature would decrease.
C) The signal to the control center that the set point had exceeded would stop being sent.
D) The signal from the control center to the blood vessels and sweat glands would stop being sent.
E) The blood vessels would constrict. Body temperature regulation is the primary example used to explain both homeostasis and negative feedback loops. If an effect does not occur, then the stimulus will continue to increase as will the rest of the functioning loop.
