• epithelial tissues serve various functions in the body. which of the following is not a function of epithelial tissue?

  • a.) protecting underlying tissue, b.) acting as a barrier, c.) permitting passage of substances, d.) synthesizing hormones
• protecting underlying tissue of epithelial tissue involves safeguarding underlying organs
• filtration is primally associated with simple squamous epithelium
• absorption is the primary function of cuboidal epithelium
• which is not the function of columnar epithelium?

  a.) absorption, b.) secretion, c.) protection, d.) muscle contraction
• skeletal muscle is primarily responsible for movement and is attached to the bone
• intercalated disks is what connects muscle cells and coordinates their contraction
• through involuntarily smooth muscle is control
• antihistamines are commonly used to block the effects of histamine. and so, preventing allergic reaction is the primary purpose of antihistamines.
• regeneration involves the replacement of damages cells with new cells of the same type. restoration of normal function is the typical outcome of tissue regeneration
• aging impact various aspects of tissue health. which of the following is not associated with aging?

  a.) skin changes, b.) athletic performances, c.) increased neutron count, d.) reduced sensory capacities
• protons play in determining the identity of an element through determining the atomic number and element type
• stable and radioactive are the two main type of isotopes
• an element named uranium can stay in a unstable form
• molecule is the smallest unit of most compound
• non-polar covalent bond involves atoms that share electron equally
• water can exist as solid, liquid, and gas within a narrow range of temperature
• solution is a mixture where components are evenly distributed
• suspension components settle out and do not remain evenly distributed
• water is essential solvent for life because it is a chemical and physical properties allow it to dissolve more substances than most other liquid
• organic chemistry primarily study carbon-based compound
• organic chemistry is crucial in biology and medicine because it explores the structure and reaction of carbon compound relevant to living organisms
• carbohydrate's primary role is to serve as a long-term energy storage
• catalyzing biochemical reactions is the diverese function of proteins
• skin is the largest organ of the human body in terms of weight
• epidermis and dermis is the two main parts that compose the skin
• the primary role of skin in protecting the body is acting as a barrier against external threaths
• keratinocytes make up most cells found in epidermis
• epidermis of the skin is responsible for synthesizing vitamin d
• keratinocytes, melanocytes, intraepidermal, macrophages, and tactile cells are found in epidermis
• dense regular connective tissue primarily makes up the dermis
• keratinocytes produce keratins
• keratin role in the skin and underlying tissue is to protect the skin and underlying tissue
• melanin pigmentation helps protect against UV radiation damage
• mechanoreceptors a type of receptor that is present in the dermis and allow sensation to extend beyond the skin surface
• melanocytes primary function is to produce melanin; group of pigments that provide skin color
• sun exposure is what triggers melanin production
• stratum corneum holds in water and keeps the skin hydrated
• papillary dermis responsibility is to provide nutrient exchange and waste removal
• reticular dermis provide skin strenght and flexibility
