### body part | organ | sense organ | chemoreceptor:

Taste bud
* Some taste buds are part of airways
  - clappers
  - epiglottises
  - mouths
  - necks
  - pharynxs
  - throats
  - tongues
  - tracheae
  - windpipes
* are body parts
  - chemoreceptors
  - collections of nerve-like cells that connect to nerves running into the brain
  - constantly regenerating
  - epithelial cells and are constantly being replaced
* are located in mouths
  - on the tongue, the soft palate, and the back of the throat
  - numerous in the tongue
  - part of tongues
  - present in the posterior surface of the epiglottis
  - solid objects
  - to tiny to see
  - usually more abundant in men than women
* become more sensitive to the natural sweetness of foods.
* begin to form on the surface of the tongue.
* contain gustatory cells which contain sensitive hair like processes
  - the taste receptor cells, which sense the presence of chemicals in the mouth
* detect gustatory stimuli.
* exist to detect toxins and identify nutrient value.
* lie at the base of the tongue, in most species of birds.
* send messages to the brain about whether the food is sweet, salty, sour, or bitter.

Lateral line
* are part of amphibians
  - fish
  - sense organs
  - the fish equivalent of hearing
  - vital for schooling , predation , and orientation
* serve an important role in schooling behavior, predation, and orientation.
  * are vital for schooling, predation, and orientation. For example, fish use their lateral line system to follow the vortices produced by fleeing prey. They are faint lines running lengthwise down each side, from the gill covers to the base of the tail.

### body part | organ | sense organ | semicircular body part:

Body canal
* A semicircular canal sense organ
* Semicircular canals detect rotation of the head due to endolymph movement against the hair cells.

Sensory organ
* Any sensory organ has different sensitivity for various types of stimulation.
* Some sensory organs detect stimuli
  - various stimuli
  - provide information
* affect the mammalian behavior.
* are few and primitive
  - highly developed
  - visual, touch, and chemoreceptive senses concentrated on the head

Sensory receptor
* Most sensory receptors are modified neurons
* Most sensory receptors respond to mechanical stimuli
* Some sensory receptors are actually specialized neurons.
* convert a sensory stimulus, such as sound, into electrical impulses.
* detect stimuli.
* is an organ
* occur in all groups.

Several organ
* Some several organs excrete waste.
* are specialized for endocrine function
  - very toxic, potentially lethal
* can work together in a system.
* work together to form an organ system.

### body part | organ | sex organ:

Female genitalia
* Inspect the labia, clitoris, urethral opening and external vaginal vault.
* sex organ

Genitalia
* also develop progressively.
* mature progressively as the proglottids move towards the rear of the organism.

### body part | organ | sex organ | genitalia:

Ambiguous genitalia
* can be a traumatizing experience for parents.
* is observed in children with a number of different genetic disorders.

Teat
* dipping with quality products major factor in preventing new infections during lactation.
* do come in different shapes and with different hole sizes.

Siphon
* appear as small pores in the surface of the tunicate.
* are hose
  - tubes
+ Scallop, Food and digestion: Bivalves
  * Most scallops are filter feeders. They eat plankton. The plankton sometimes has scallop larvae in it. Siphons bring water over a filtering structure. Mucus then traps the food. Next, the cilia on the structure moves the food to the mouth. Then, the scallop digests the food in the stomach and digestive gland. Waste goes through the intestine and exits through the anus.
