Cells, tissue and homeostasis

Question 1

Cells can be grouped together to form many things, can you name them?

Answer 1

Muscle
blood
bone

organs such as heart liver and stomach

Question 2

Can you name all the cells?

Answer 2

muscle cell
sex cell
stem cell
bone cell
blood cell
nervous cell
epithelial cell
immune cell
fat cell

Question 3

What do cells do?

Answer 3

utilise glucose water and oxygen to make energy ATP

they synthesis new substances such as proteins sugars fats ect

they produce specialised substances

they secrete specialised substances

they differentiate to preform specialised tasks

they can grow and devide to pass on genetic material

Question 4

What is the function of a cell membrane?

Answer 4

protection

regulation

communication

identity

Question 5

how do things transport across the membrane

what are the two types of transport

Answer 5

active and passive transport

Question 6

what is the point of passive transport

Answer 6

diffusion
facilitated diffusion
osmosis

Question 7

what is the point of active transport

Answer 7

sodium potassium pump
pinocytosis abd phagocytosis

Question 8

what does organelles mean

what does each part have

Answer 8

small organ

each has highly specialised structures to carry out different functions

Question 9

What are the 4 main types of tissue

Answer 9

epithelial - covering lining and secreting

connective - protects and supports

muscle - movement

nervous - control

Question 10

what does epithelial tissue do

how does it protect

how does it secrete and absorb

Answer 10

covers and lines the body

protects underlaying structures from dehydration and chemical mechanical damage

mucos is secreted from the lining and absorbs substances.
such as enzymes being secreted from the lining of the small intestine such as absorbing nutrients from food

Question 11

structure of epithelial tissue

Answer 11

highly packed cells with minimal space between them

can usually lie on an inert basement membrane - inactive

can be very single layered or several layers

Question 12

what is the most common tissue in the body?

Answer 12

connective tissue

Question 13

how does the connective tissue work?

Answer 13

cells separate from each other compared to the cells in the epithelia tissue

Question 14

what are the supportive networks in connective tissue?

Answer 14

binding
protection
transport
insulation

Question 15

what cells are found in connective tissue?

Answer 15

fibroblasts - large, collagen and elastic fibres which provide structural support around the body

Question 16

what other cells are found in connective tissue?

Answer 16

Fat cells - adipocytes
Macrophages - parts of immune system - phagocytic
leukocytes - white blood cells
mast cells - release of histamine in response to external invaders

Question 17

What cells are in adipose tissue
where can you find this tissue
what does it do

Answer 17

fat cells
skin heart and kidneys
protects energy reserve and reduces heat loss

Question 18

LOOSE CONNECTIVE TISSUE

what does it do
how many cells does it have
where is it in the body

Answer 18

randomly arranges protein fibres which results in strength elasticity and support

many different cells

its in and around most body structures

Question 19

FIBROUS CONNECTIVE TISSUE

what does it do

what is the structure of it

Answer 19

regularly arranges protein fibres in rows which forms tendons and ligaments

it is strong and can withstand pulling

Question 20

CARTALIGE

what is it made up of

where is it in the body

what does it do

Answer 20

protein fibres like gel around substances such as chondrocyte cells

ends of long bones such as the nose, larynx trachea and bronchi

it allows for movement

Question 21

3 types of muscle tissue?

Answer 21

Skeletal

smooth

cardiac

Question 22

What are the cells in the nervous tissue

Answer 22

Excitable cells - neurons
Non excitable cells - glial cells

Question 23

What can effect homeostasis

Answer 23

temp
water pH
blood glucose levels
blood tissue oxygen and co2 levels
blood pressure
