-
Fibrous Connective Tissue
Very dense due to large amounts of collagenous fibers and forms tendons and ligaments
-
Adipose Tissue
A specialized form of loose connective tissue which stores fat.
-
Phagocytosis
Occurrs when a leukocyte engulfs a bacteria and breaks them down.
-
Macrophages
Amoeboid cells which roam fibers and engulf bacteria and debris of dead cells (called Phagocytosis).
-
Fibroblasts
Secretes the protein ingredients of the extracellular fibers.
-
Loose Connective Tissue
Binds epithelia to underlying tissues and acts as packing material and holds organs in place.
-
Reticular Fibers
Made of collagen, are thin and branched, not too strong, forms a tightly woven fabric that joins connective tissues to adjacant tissues.
-
Elastic Fibers
Long threads of elastin, is rubbery and elastic.
-
Collagenous Fibers
Made of collagen, these fibers are fairly thick, nonelastic, and fairly strong.
-
Connective Tissue
Tissue which consists of a sparse population of cells spread through an extracellular matrix. It holds things together and keeps separate organs from joining into one.
-
Epithelial Tissue
Sheets of tightly packed cells which cover the body and line the organs and acts as a barrier between organs and body and the outside world.
-
Columnar Cells
A type of epithelial tissue which is shaped like bricks set on end and are present in nasal passages, intestinal lining, and inner surface of urethra.
-
Cuboidal Cells
A type of epithelial tissue which is dice-shaped and are present in kidney tubules.
-
Squamous Cells
A type of epithelial tissue where cells are flat and are present in blood vessels, air sacs, skin, and lining of esophagus, anus, and vagina.
-
Cartilege
An abundance of collagenous fibers embedded in a rubbery matrix made of chondroitin sulfate.
-
Bone
A form of mineralized connective tissue.
-
Blood
Consists of plasma and blood cells and transports fluids throughout body.
-
Nervous Tissue
A type of tissue which senses stimuli and transmits signals.
-
Cardiac Muscle
Composed of branched cells and located in the heart.
-
Nonshivering Thermogenesis (NST)
A type of thermoregulation which mammals and birds ONLY can perform where metabolic activity occurs within mitochondria, resulting in heat production.
-
Specializations that Mammals and Birds use for Thermoregulation
Muscle Activity (shivering), Torpor (hibernation), and Nonshivering Thermogenesis (NST).
-
Ectotherms
Animals whose body heat is close to the temperature of the environment; are conformers to the environment.
-
Endotherms
Animals who use metabolic heat to keep their body temperature higher than that of the environment; are regulators.
-
Chrondocytes
Secretes collagen and chondroitin sulfate, which make a strong and flexible support system.
-
Osmoregulation
Regulating solute balance and the gain/loss of water.
-
Adaptions that Help Animals Thermoregulate
Insulation/Sweating, Vasodilation (warm the skin = heat loss), Vasoconstriction (keeps the warm blood inside body), Countercurrent heat exchange (reduces heat loss to environment), Behavioral Responses (ie: going to the shade when it's hot), and Changing the rate of metabolic heat production (increase or decrease)
-
Tissues
Groups of cells with a common structure and function.
-
Tendons and ligaments are examples of what type of connective tissue? A Blood, B Bone, C Cartilage, D Loose connective tissue, or E Fibrous connective tissue?
E. fibrous connective tissue
-
Another year and a poor dog is still sitting on a rock. The dog starts
panting to cool down its body temperature.
This type of heat transfer is called: A Countercurrent exchange, B Radiation, C Conduction, D Convection, or E Evaporation?
E. evaporation
