support structure.
Components of the integumentary system are:
skin, nails, hair and the glands and nerves
_______describes the composition of substances and how chemicals react with each other.
What is chemistry?
The shape of cells make possible their __________.
Function.
Is a sack of five to eight flattened, membranous sacs that resemble pancakes. This organelle refines, packages, and transports proteins synthesized on ribosomes
What are Ribosomes?
The skeletal system is also called the ________________________________ system.
musculoskeletal system.
is the largest and heaviest organ in your body.
The skin.
Is the most abundant compound in the body and is solvent in which chemical reactions occur.
What is water?
A human body has about ___ cells.
What is 30 trillion?
Are elongated, fluid-filled sacs that house most of the biochemical reactions that extract energy from the nutrients in digested food.
What are mitochondria?
Some bones protect your internal organs. For example, (provide three examples)
your skull safely encloses your brain, and your ribcage shields your heart, lungs and other organs near your chest.
The three layers of the skin are:
Epidermis, dermis, and hypodermis.
•Biomarkers are chemicals in the body that clinicians can measure to indicate a disease or exposure to a toxin1. They can provide valuable information about the body’s response to various environmental exposures and help in diagnosing and monitoring health conditions. Some common examples of biomarkers are:
Blood Pressure, Body Temperature, LDL Cholesterol Level, Red Blood Cell Count, Blood Glucose Levels.
Nearly all cells have a complete set of genetic instructions (the genome), yet they use only some of this information. This selective reading is called
What is gene expression?
Are tiny membranous sacs that house enzymes that dismantle debris.
What are lysosomes?
•Bone marrow is a soft, fatty tissue that produces critical cells, including:
Red blood cells (cells that carry oxygen throughout your body).
•White blood cells (cells that fight infections).
•Platelets (cells that control bleeding).
Nails protect the ends of your fingers and toes. The anatomy of your nail consists of:
•Nail plate, nail bed, cuticle, matrix, and lunula.
Deals with the structure (morphology) of body parts-their forms and how they are organized.
What is anatomy?
A cell includes a __________, ___________, __________.
What are cell membrane, cytoplasm, and a nucleus?
Are the series of changes that a cell undergoes, from the time it forms until it divides,
What is cell cycle?
There are two types of bone marrow in your body, which are characterized by their color.
Red bone marrow and yellow bone marrow.
They release materials like water, salt or oil from under your skin to the surface of your skin.
What are glands?
Are the basic units of structure and function that form the body.
Cells
The cell membrane forms the outermost limit of the living material. It is a _______ passageway that controls the entrance and exit of substances
What is selectively permeable?
Houses the genetic material (DNA), which directs all cell activities.
What is cell's nucleus?
