Q

Essay question:
Describe negative feedback

A

Negative feedback is a process that is meant to reverse the original trigger. This is by having the original stimulus, which is then received by a receptor which uses the afferent pathway for sensory information to go to the integrating sensor which then uses an efferent pathway which is the motor information and that goes to the effector which then goes to the response

A

“Garbage disposal”
Gets rid of the bad stuff
Clean up cellular debris

25
Q

What does cilia do?

A

Moves materials across the cell storage

26
Q

What does the Integumentary system do?

A

Forms external body covering; insulates and cushions deeper body organs; regulates heat loss; synthesizes vitamin D

27
Q

What are the functions of the Skeletal system?

A

Protect and support body organs; provides framework muscles use to cause movement; stores minerals

28
Q

What are the functions of the Muscular system?

A

Allows manipulation of the environment, locomotion, and facial expression; maintains posture; produces heat

29
Q

What are the functions of the Nervous system?

A

Fast-acting control system of the body; responds to internal and external changes by activating appropriate muscles and glands

30
Q

What are the functions of the Endocrine system?

A

Glands secrete hormones that regulate processes such as growth, reproduction, and nutrient use by body cells

31
Q

What are the functions of the Cardiovascular system?

A

Blood vessels transport blood which carries oxygen, nutrients, hormones, carbon dioxide, wastes
Heart pumps blood

32
Q

What are the functions of the Lymphatic system?

Picks up fluid leaked from blood vessels and returns it to blood; disposes of debris in the lymphatic stream; houses white blood cells involved in immunity

33
Q

What are the functions of the Respiratory system?

A

Keeps blood constantly supplied with oxygen and removes carbon dioxide; gas exchange occurs through the walls of the air sacs of the lungs

40
Q

What are buffers?

A

Substance that resists changes in pH by
donating a H+ when pH is too basic
or
accepting a H+ when pH is too acidic

Move and store energy, absorb vitamins and make hormones
Triglycerides, Phospholipids, steroids

44
Q

What are the general functions of Proteins?

A

Provide construction materials for body tissues, play vital role in cell function, act as enzymes, hormones, and antibodies
Build from amino acids

Q

What does DNA do?

A

Genetic code
Codes for specific proteins

46
Q

What are the bases (and their partner in DNA?

A

No

48
Q

What is simple diffusion?

A

The process in which a substance moves through a semipermeable membrane without any help

49
Q

What is Facilitated diffusion?

A

The transport of a substance through the semipermeable membrane with help of a transport molecule (channel or carrier)

50
Q

What is Osmosis?

A

Simple diffusion of water

  • Osmotic pressure (pulling water) is the drive for osmosis
51
Q

Does Active transport require ATP?

A

Yes

52
Q

What is Active transport?

A

Amino acids and ions transported by proteins carriers known as solute pumps
Substances moved against gradient from [LOW] to [HIGH]

53

A

Ability of solution changes the tone (shape) of a cell

54
Q

What are the three types of tonicity?

A

Hypertonic (shrink)
Hypotonic (swell or burst)
