physiology 1 levels of organisation

Question 1

what are the 6 levels of organisations?

Answer 1

chemicals 
cellular 
tissues
organs 
body systems
organism

Question 2

what does cellular control?

Answer 2

it controls exchange of material between cell and the environment

Question 3

what does cellular perform?

Answer 3

glucose+oxygen—> water+energy(ATP)

Question 4

What does cellular synthesise?

Answer 4

its synthesizes cellular components e.g. proteins

Question 5

what does cellular do?

Answer 5

sense and respond to changes in the environment

reproduction

Question 6

what are the 4 primary types of tissues

Answer 6

muscle tissue
connective tissue
nervous tissue
epithelial tissue

Question 7

what does the muscle tissue do

Answer 7

movement (skeletal, cardiac, smooth)

Question 8

what does epithelial tissue do

Answer 8

function and protection

Question 9

what does nervous tissue do

Answer 9

rapid internal communication (brain, spinal cord, nerves)

Question 10

what does connective tissue do

Answer 10

supports and protects body organs.

also binds the tissues together.

Question 11

what tissues are involved in GIT (organ)

Answer 11

• It is lined with epithelial tissue
  
  • The walls contain smooth muscle so it has muscle tissue
  • Nervous tissue in GIT controls muscle contraction and gland secretion.
  • Connective tissue bind all the above tissues together

Question 12

what are the 11 body systems? (numerics rid)

Answer 12

• Nervous- BSP
  
  • Urinary- KUUB
  • Muscular- skeletal muscle
  • Endocrine- all hormone secreting tissue (SPAGHETTI PPHHK)
  • Respiratory- BLLNTP
  • Immune- ABWATTS LG
  • Circulatory- HBBV
  • Skeletal- BCJ
  • Reproductive- male- APPS GBT female-GOBO U
  • Integumentary- SHN
  • Digestive- PEGLESSS ML

Question 13

describe epithelial cells

Answer 13

Cells are tightly attached together and line hollow organs, e.g., blood vessels or digestive organs, or cover surfaces, e.g., skin

Question 14

describe nerve cells

Answer 14

Cells are specialized for communication. Motor neurons send signals from the brain to muscles and glands to control functions. Sensory neurons relay sensory information from the body’s internal or external environment to the brain

Question 15

describe muscle cells

Answer 15

Cells are specialized for contraction and produce movement. There are three kinds of muscle cells: (1) Skeletal, (2) Cardiac and (3) Smooth muscle

Question 16

describe connective cells

Answer 16

A diverse group of cells, e.g., cell types can provide structural strength, e.g., fibroblasts, fat, bone and cartilage, or form the blood and immune system
