Sensory Receptors and the Human Body: Functions and Systems
What is the Mission of Sensory Receptors?
They are responsible for receiving and transmitting information from outside the nervous system.
What is the Mission of the Effectors?
Effectors are responsible for carrying out the response developed by nerve centers. The response may be secretory or motor.
Sensory Receptor Types
What sensory receptor types are known?
- Photoreceptors: They detect light stimuli and are located in the eyes.
- Mechanoreceptors: These are stimulated by mechanical changes, pressure, contact,
Human Sensory System: Receptors, Organs, and Health
The Role of Relationship in Sensory Processes
The role of relationship involves three groups of processes: the reception of stimuli, processing of information for the development of coordinated responses, and execution of responses. Humans have specialized organs to carry out these processes: receptor organs, systems of coordination, and effector organs.
Reception of Stimuli
A stimulus is a change in our environment or within us that we perceive and provokes a response from our body. Receptor cells

Digestive System: Enzymes and Hormonal Regulation
The digestive system involves processes such as digestion, motility, absorption, and secretion. Key enzymes and their functions include:
- Pepsin: Digests proteins; released as pepsinogen by chief cells.
- Lipase: Digests fats into two fatty acids and monoglycerides.
- Trypsin, Chymotrypsin, Elastase: Digest proteins into peptide fragments.
- Carboxypeptidase: Splits off the terminal amino acid from the carboxyl end of a protein.
- Amylase: Breaks polysaccharides
Key Biological and Geological Concepts Explained
Habitat
The place where an organism lives. It is normally characterized by physical features of the environment and dominant vegetation. A lake, a meadow, or a pond are examples of habitats.
Metamorphosis
A process of change from larva to adult that occurs in many invertebrates and amphibians.
Sporangia
The spore-producing organs of some plants and fungi.
Placenta
An organ made of maternal and fetal parts that allows the exchange of substances between the fetus and the mother during the embryonic development

Immunology
Immune: The property of being invulnerable to a specific disease (usually surmountable). Immunology is specific (like chickenpox) and can be lifelong (like typhus), and should not be confused with disease resistance. Immunology is the science that studies immunity and the immune system.
Types of Immunity
Congenital Immunity (inherited):
- Species: Present in all individuals of a species.
- Race: Present in certain groups or populations of a species.
- Individuals: Present only in a particular individual.
