Definition
Binds cells and fiber in connective tissue.
Term
Areolar Tissue
Definition
Loose connective tissue found in lymph nodes. Forms a soft skeleton to support lymph nodes.
Term
Adipose Tissue
Definition
Loose connective tissue found all over the body or ubiquitously. Insulation, protection and food source.
Term
Reticular Tissue
Definition
Loose connective tissue located in the live, spleen, lymph nodes.Forms a soft skeleton (stroma) to support the lymphoid organs.
Term
Dense Regular
Definition
Fibrous connective tissue located in tendons, ligaments, aponeurosis. Forms a soft skeleton to support structures.
Term
Elastic Connective Tissue
Definition
Fibrous connective tissue. No photo.
Term
Hyaline Cartilage
Definition
Cartilage connective tissue. End of longs bones. Reduce friction.
Term
Elastic Cartilage Tissue
Definition
Cartilage connective tissue. Epiglottis and ears. Flexible, deforms and goes back.
Term
Fibrocartilage
Definition
Pubic symphysis, intervertebral disks, and meniscus. Weight bearing and slightly flexible. (Like a ball joint on a car’s suspension)
Term
Compact Bone
Definition
Bone tissue. Found in skeleton. Produces blood, stores minerals and used for structure.
Term
Mesenchyme
Definition
Loosely organized, mainly mesodermal embryonic tissue that develops into connective and skeletal tissues, including blood and lymph.
Term
Erythrocytes
Definition
Red blood cells. Carry nutrients and waste. O2 and CO2.
Term

Definition
Bones and organs. Voluntary and Striated.
Term
Cardiac Muscle
Definition
Found in heart. Involuntary and Striated.
Term
Smooth Muscle
Definition
GI tract hollowed organs. Peristalsis. Involuntary and non-striated.
Term
Crenation
Definition
Cells shrink due to hypertonic solution (blood in ocean).
Term
Hemolysis
Definition
Red blood cells bursting.
Term
Hypertonic
Definition
High pressure pushing in on the cell. (Ocean saline greater than cell so it crushes it).
Term
Hypotonic
Definition
Low pressure from cell wall. (Too much water and cell bursts).
Term
Isotonic
Definition
Same pressure inside and out. (Cell has same saline as solution). Equilibrium.
Term
Osmosis Pressure
Definition
Pressure exerted on the semi-permeable membrane.
Term
Dialysis
Definition
Separation of two substances in solution by the difference in their rates of diffusion through a semipermeable membrane.
Term
Hyperosmotic
Definition
Osmolality greater than that of another fluid.
Term
Hyposmotic
Definition
Osmolality less than that of another fluid.
Term
Isosmotic
Definition
Osmolality of equal value to another fluid.
Term
Osmolarity
Definition
Concentration of solution. Osmoles of solute/liters of solution.
Term
Passive Process
Definition
Kinetic Energy ONLY. Concentration Gradient from a high to a low.
Term
Diffusion
Definition
Movement of a SOLUTE. Preferred method, if unavailable then osmosis.
Term
Osmosis
Definition
Movement of a SOLVENT. Membrane does not allow movement of a specific solute. Semipermeable. Solvent movement.
