22
Q

How is the pH scale read?

A
  • The Lower the pH the more Acidic

- The Higher the pH the more Basic

23
Q

What is normal human blood pH

24
Q

What is the Law of Mass Action?

A
  • When protein binding is at equilibrium, the ration of the bound and unbound components remains constant

Co2+H2o — H2Co3 — HCo3-+H+

25
Q

What is a Bicarbonate anion?

A
  • (First Responder) Buffer that moderates changes in pH

- Will bind with carbonic acid

A

group of microtubules, organizes chromosomes during mitosis

42
Q

Simple Squamous

A

Location: blood and lymphatic vessels, air sacs of lungs, lining of the heart

Function: secrets lubricating substance, allows diffusion and filtration

43
Q

Simple Cuboidal

A

Location: secretory ducts of small glands, kidney tubules

Function: allows secretion and absorbtion

44
Q

A

Location: Urinary bladder, Renal pelvis, Ureters

Function: allows to stretch and expand

50
Q

Dense Regular Tissue

ALT

A

connective tissue is mainly made up of collagen fibers. It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis.

51
Q

Dense Irregular

WEGTDW

A

Dense woven network of collagen fiber found in the dermis of the skin, in glandular tissue, in the walls of organs, and in the whites of the eyes.
