Cards

Term
Describe Lactic Acid
Definition
Produced in the muscles when glucose is broken down during strenuous exercise.
Term
Describe Protein Denaturation
Definition
When a protein looses its shape and function due to a hostile environment (temperature, change in Ph levels)
Term
Describe Catabolism
Definition
The breaking down of glucose, fatty acids and amino acids for obtaining energy and heat
Term
Describe Anabolism
Definition
Simpler molecules combining to form complex compounds.
Term
What is the difference between Microvilli and Cilia
Definition
Microvilli found in epithelial cells increases surface area for absorbtion located in stomach. Cilia used for motility of solids such as phelm located in respiratory tract
Term
Describe Diffusion
Definition
A form of passive transport where substances such as oxygen and carbon dioxide diffuse through the cell membrane without the use of ATP
Term
Describe Endospores
Definition
Endospores are produced by bacteria when conditions become undesirable. They lay dormant until conditions change
Term
Describe buffers
Definition
Buffers contain hydroxyl ions and regulate acidity levels in a solution
Term
Describe the Langerhan cell
Definition
Engulf pathogens on our skin are part of the immune response
Term
Describe Merkel cells
Definition
Sensory cells that respond to touch
Term
Melanocytes
Definition
Produce melanin, protect us from uv rays and give skin its colour
Term
Keratinocytes
Definition
Produce keratin that's used in skin for waterproofing
Term
Describe the bacterial capsule
Definition
Helps prevent the cell from drying out, helps bacteria stick to the host, protects the bacteria from being eaten by the white blood cells.
Term
Describe the superbug and give an example
Definition
Micro organism that is resistant to antibiotics. It is hard to treat example is MRSA
Term
What is phagocytosis
Definition
The process of cell eating
Term
What is the genetic code
Definition
DNA, has double helix, found in the nucleus,
Term
What is the function of the Integumentary system
Definition
Regulates body temp, has sensory receptors, and aids in the synthesis of vitamin D
Term
Describe the Arrector pilli
Definition
Smooth muscle that attaches hair follicles to the tissue and when stimulated contracts causing hair to stand on end (goose bumps)
Term
Where is the vascular skin layer located and why
Definition
Dermis layer of the skin, because it has veins and arteries running through it
Term
What are the 4 layers of the Epidermis
Definition
Germativum, Spinosum, Granulosum, Lucidum, Corneum (Germs, Spread, Gradually, Like, Crabs)
Term
Describe bacteriophage
Definition
Virus that infects a bacteria cell, it injects its genetic material in the cell, it then multiplies until the cell bursts and millions of bacteriophage are formed (example E.coli)
Term
What is E.coli
Definition
Resident flora found in the intestine
Term
What is the purpose of gram staining
Definition
To identify bacteria and determines which antibiotic to use.
Term
What is a virus
Definition
Obligate Intracellular Parasite. For them to behave like a living cell and reproduce they need to be inside a host cell.
Term
What are the layers of the skin
Definition
Epidermis (outer layer), Dermis, Subcutaneous (hypodermis)
Term
What are Epidermal Ridges
Definition
They sit on top of the dermal papillae. Function to increase the grip by increasing friction, everyone has their own unique set of fingerprints.
Term
What the characteristics of Stratum Germinativum (basale)
Definition
Always dividing by mitosis, all layers of the skin are produced from this layer.
Term
Function of the Eccrine sweat gland
Definition
Cool us down
Term
Function of Apocrine gland
Definition
Give us odour
Term
Arrector pilli
Definition
Create goose bumps
Term
Describe Normal or Resident Flora
Definition
Micro organisms that normally inhabit the human body and do not cause disease in normal circumstances (Candida albicans found in vagina, E.coli found in intestine)
Term
Function and location of Resident Flora
Definition
Protects the body against disease causing organisms, cannot be washed off the body located in ears, eyes upper R. tract
Term
What is the location and function of E.coli
Definition
Located in intestines, involved in the synthesis of vitamin k, breakdown of fibre in diets
Term
What is the purpose of the bacteria cell wall
Definition
Maintains and protects cell and cell shape
Term
What is the function of flagellum
Definition
Thin filament that creates propeller like movement
Term
What is the function of fimbriae
Definition
Projections that attach bacteria to surfaces
Term
Describe antibiotics
Definition
Substance produced by micro organisms to destroy or inhibit grown of other micro organisms
