answers
-lysis Ans✓✓✓ breakdown of a cell caused by damage to its plasma
membrane
4 types of animal tissue Ans✓✓✓ 1. Epithelial
2. Connective
3. Muscle
4. Nervous
active transport Ans✓✓✓ Energy-requiring process that moves
material across a cell membrane against a concentration difference
adipose connective tissue Ans✓✓✓ Function: provides reserve fuel;
insulates against heat loss; supports and protects organs
Location: under skin, around kidneys and eyeballs, within abdomen, in
breasts.
adrenocorticotropic hormone (ACTH) Ans✓✓✓ regulates the
endocrine activity of the adrenal cortex
pituitary gland
,Anterior (ventral) Ans✓✓✓ front of the body
antidiuretic hormone (ADH) Ans✓✓✓ reduces urinary output
pituitary gland
apical (free) surface Ans✓✓✓ the surface of the epithelial cell that
faces the body surface, a body cavity, the lumen of an internal organ, or
a tubular duct
areolar (loose) connective tissue Ans✓✓✓ Binds skin to underlying
organs; Forms delicate, thin layers between muscles; Fills in spaces
underneath epithelia;
It is characterized by an abundance of ground substance, plus thin and
relatively few fibres and cells The main cellular elements are fibroblasts
and a smaller amount of adipocytes.
Located in the skin, areolar tissue binds the outer layers of the skin to
the muscles lying underneath. They are also found in, around the
mucous membranes, surrounding nerves, blood vessels and various
other body organs. Its functions are as follows: Supports the internal
organs.
, arrector pili Ans✓✓✓ a smooth muscle attached to hair follicles that
causes "goose bumps" to appear on the skin when contracted
basal lamina (basement membrane) Ans✓✓✓ a layer of filaments and
fibers that attach an epithelium to the underlying connective tissue
basal lamina (basement membrane) Ans✓✓✓ a layer of filaments and
fibers that attach an epithelium to the underlying connective tissue
Biological Hierarchy Ans✓✓✓ cells, tissues, organs, organ systems,
organisms
calcitonin Ans✓✓✓ decreased blood calcium levels by stimulating
calcium depositing in the bones
thyroid gland
ciliated pseudostratified columnar epithelium Ans✓✓✓ Ciliated
pseudostratified columnar epithelia is the type of respiratory
epithelium found in the linings of the trachea as well as the upper
respiratory tract, which allows filtering and humidification of incoming
air.
collagen fibers Ans✓✓✓ a protein substance found in bone and
cartilage, provides flexibility and strength
