19
Q

what cells are in the blood

A

red and white blood cells in a fluid matrix

20
Q

what are the two types of CT proper

A

1.) loose
2.) dense

21
Q

what types are loose CT

A

1.) Areolar
2.) Adipose
3.) Reticular

22
Q

what are the types of dense CT

A

1.) Irregular
2.) Regular
3.) Elastic

23
Q

what is the function of areolar CT

A

support and bind to other tissues
hold body fluids
defended body against infection
storing nutrients as fat

24
Q

what are the functions of adipose CT?

A

storing nutrients as fat
surrounds and protects organ

25
Q

what is the function of reticular CT?

A

for an internal skeleton and provide structural support

26
Q

what is the function of irregular CT

A

withstands tension and provides structural support

27
Q

what is the function of regular CT

A

withstand tension and attached to ligaments and tendons

28
Q

what is the function of elastic CT

A

allows tissue to recoil
pulsate flow through arteries
aids in passive recoil of lungs the following inspiration

29
Q

what is cartilage CT tissue?

A

resists compression and tension
provides support
consists of cells separated by a matrix containing fibers, ground substance, and tissue fluid

30
Q

what are the types of cartilage CT?

A

1.) Hyaline
2.) Elastic
3.) Fibrocartilage

31
Q

what is the function of hyaline cartilage?

A

support and reinforcement
serves as resilient cushion
resists compressive stress

32
Q

what is the function of elastic cartilage?

A

maintain shape while allowing great flexibility

33
Q

what is the function of fibrocartilage?

A

absorb compressive shock

34
Q

what is bone CT?

A

provides support and protection

35
Q

what is the function of blood CT?

A

transports respiratory gases, nutrients, wastes, cells

36
Q

what is the cutaneous membrane?

A

skin
an outer epithelium is a think epidermis with an inner CT dense dermis

37
Q

what is mucous membrance

A

lines the inside of any organ that opens to the outside of the body

38
Q

what is the serous membrane?

A

slippery membranes that line the closed pleural, pericardial, and peritoneal cavities.

39
Q

what is the function of muscle tissues?

A

body movements

40
Q

what are the 3 types of muscle tissue?

A

1.) skeletal
2.) cardiac
3.) smooth

41
Q

what is the function of nervous tissue?

A

transmit signals from sensory receptors and to effectors

42
Q

what do dendrites do

A

processes that extend from the cell body that transmit signals towards the cell body

43
Q

what do axons do

A

long process that extends from the cell body to transmit signals away from the cell

44
Q

what does neuroglia do

A

nonconducting cells that nourish, insulate, and protect neurons
