Location: Male urethra, glandualr ducts
Function: secretes, portects

18
Q

Transitional

A

Location: lining of the bladder, urethra, ureters

19
Q

What are the two types of glands

A

Exocrine glands and Endocrine glands

20
Q

Exocrine glands

A
  • Cells that secrete (sweat, ear wax, saliva, digestive enzymes)
    onto body surfaces or into body cavities
  • Connected to the surface by tubes (ducts)
21
Q

2) Endocrine gland

A
  • Secrete hormones which move into the bloodstream or lymphatic
    fluid to travel to target organs
  • Often called ductless glands
22
Q

Merocrine

A

Exocrine gland: Merocrine gland secrete their product by exocytosis ( sweat glands and the salivary glands.)

23
Q

Holocrine

A

The entire secretory cell ruptures, releasing secretions and dead cell fragments (sebaceous glands of the skin and the meibomian glands of the eyelid)

24
Q

Osmosis:

A

The movement of water [SOLVENT (a fluid)] from an area of high concentration an area of high concentration to a low concentration through a semi-permeable membrane.

25
Q

Diffusion

A

The movement of [Solute: iron] from an area of high concentration to low concentration

26
Q

A red blood cell was placed into a solution that was isotonic, hypertonic or hypotonic. what is the affect on the cell and why

A

Hypertonic: High concentration in the red blood cell 2% NaCI (moves
Isotonic: Similar Equilibrium 0.9% NaCI
Hypotonic: Low concentration in the red blood cell 0% NaCI

27
Q

What are the different type of CAMs: Cell Adhesion Molecules

A

Tight Junctions:
Desmosomes:
Gap Junction:

28
Q

What are the different types of muscle

A

skeleton muscle, smooth muscle, cardiac muscle

29
Q

Two type of Connective Tissue Proper

A

1) Loose connective tissue; supports structures that it surrounds
2) Dense Connective tissue: highly fibrous (collagen)’ little vascularization; reinforces and binds structures

30

1) Cartilage
2) Bone
3) Blood
