Glands and connective tissue

Question 1

are secretory organs. They are composed primarily of epithelium, with a supporting network of connective tissue.

Answer 1

Glands

Question 2

Glands that secrete their products into ducts that lead to an
external surface or into body cavities

Answer 2

Exocrine gland

Question 3

Secrete sebum (oil) to lubricate
skin and hair

Answer 3

Sebaceous gland

Question 4

Produce saliva, aiding in digestion
and oral health.

Answer 4

Salivary gland

Question 4

Help regulate body temperature by
releasing sweat

Answer 4

Sweat gland

Question 5

Produce milk in females.

Answer 5

Mammary gland

Question 6

Secrete gastric juices for digestion in
the stomach.

Answer 6

Gastric gland

Question 7

Glands that secrete hormones directly into the bloodstream, where
they travel to target organs or tissues.

Answer 7

Endocrine glands

Question 7

Releases digestive enzymes
into the small intestine.

Answer 7

Pancreas

Question 8

Regulates other endocrine glands and
various bodily functions.

Answer 8

Pituitary gland

Question 9

Produces insulin and
glucagon to regulate blood sugar levels

Answer 9

Pancreas (endocrine part)

Question 9

Produces hormones that
regulate metabolism

Answer 9

Thyroid gland

Question 10

Produce hormones related to stress
response and metabolism

Answer 10

Adrenal gland

Question 11

Exocrine secretions can be
enzymes, sweat, or mucus; endocrine secretions are
always hormones

Answer 11

Type of secretion difference

Question 11

Exocrine glands use ducts to
transport their secretions, while endocrine glands
release hormones directly into the bloodstream.

Answer 11

Secretion method difference

Question 12

Classifications of connective tissues

Answer 12

Embryonic, adult connective, supporting, fluid

Question 13

A diverse primary tissue type that makes up
part of every organ in the body. This tissue is the most abundant in the body

Answer 13

Connective tissue

Question 14

Functions of connective tissue

Answer 14

Functions
1. Enclosing and separating other tissues.
2. Connecting tissues to one another.
3. Supporting and moving parts of the body.
4. Storing compounds.
5. Cushioning and insulating.
6. Transporting.
7. Protecting.

Question 15

3 types of adult connective tissue

Answer 15

1. Connective tissue proper - loose and dense
2. Supporting connective tissue - cartilage and bone
3. Fluid connective tissue - blood

Question 16

Connective tissue proper contains?

Answer 16

Loose Connective Tissue:
➔ Includes areolar (packing material), adipose (stores fat,
insulates, protects), and reticular (forms framework for
organs like spleen, and lymph nodes).
Dense Connective Tissue:
➔ Subdivided into regular (collagen fibers aligned in one
direction; found in tendons, ligaments) and irregular
(fibers arranged randomly, giving strength in multiple
directions; found in skin, organ capsules).
Elastic Connective Tissue:
➔ Found in structures needing elasticity (e.g., vocal cords,
arteries).

Question 17

2 types of bones in supporting connective tissue

Answer 17

1. Spongy bone has spaces between trabeculae, or
   plates, of bone and therefore resembles a sponge.
2. Compact bone is more solid, with almost no space
   between many thin layers, or lamellae of bone.

Question 18

Composed of cells in a rigid matrix. Surrounded by
perichondrium, no blood vessels or nerves.

Answer 18

Cartilage

Question 19

Types of cartilage

Answer 19

1. Hyaline: Smooth, glassy, found in ribs and joints.
2. Fibrocartilage: Tough, found in areas with high
   pressure (e.g., knees).
3. Elastic: Rigid yet elastic, found in ears

Question 20

Hard connective tissue with living cells in a mineralized
matrix.

Answer 20

Bone
