Homeostasis

is the ability of the body to maintain a constant internal equilibrium. It keeps the body functioning well even when there are changes in the environment. It also needs constant monitoring.

Homeostatic Regulation

these are the adjustments na ginagawa ng katawan kapag nagkaroon ng change sa environment.

Receptor

is a sensing component that monitors changes in the organism's / structure's environment.

Thermoreceptor

receptor specifically for temperature

Hypothalamus

specific gland na nakakareceive ng neurons from the receptor

Stimulus/Stimuli

a factor na magdadala ng change sa katawan ng tao.

Control Center

It receives messages from the receptor. This is usually associated with the nervous system.

Effector

It receives the messages from the control center.

Afferent Pathway

It carries the nerve impulses to the central nervous system (CNS). These signals are carried by the afferent neurons (receptor to control center).

Efferent Pathway

It carries the nerve impulses from the central nervous to effector organs through the efferent pathway. (control center to effector).

Osmoregulation

It refers to the continuous regulation of the osmotic pressure. It is important for maintaining the balance between solutes and fluids in the body. (It occurs sa tao through pag-ihi)

Osmotic Pressure

is the measurement of the tendency of water to move from one side of the solution to another.

Hypotonic

mas marami ang solvent kesa sa solute

Hypertonic

mas marami ang solute kesa sa solvent

Isotonic

equal ang amount ng solute at solvent

Thermoregulation

this process is involved in maintaining body temperature. This is necessary to maintain a normal metabolic function.

Thermoconformers

Cold-blooded. They copy the temperature of their environment.

Thermoreceptors

Warm-blooded. They regulate their body temperature.

Ectothermic

other term for thermoconformers

Endothermic

other term for thermoreceptors

Chemoregulation

This controls the amount of solute present in the body fluids to regulate asmotic pressure.

Positive Feedback Mechanism

It occurs when the changes are strengthened by the response of the effector. The rate of this process increases as the concentration of the product increases.

Oxytocin

hormone na inilalabas during baby's exit for contraction.

Cervical Dilation

process wherein nag-oopen ang cervix.

Cervical Effacement

process wherein numinipis ang cervix.

Myometrium

The _________ will contract during childbirth.

Proteins and hormones

As a response to the presence of wounds, the body releases ________ and _________

Platelets

Ano ang iaattract ng proteins at hormones?

Platelet plug

Once maattract ang platelets, they will create a _________

Scub

a protective tissue that covers damaged skins.

increases

The levels of GnRH and LH in the blood _________ because of the positive effect.

Negative Feedback Mechanism

It occurs when the change in the body caused by stimuli, reverses as a response of a particular effector. In order for the negative feedback to occur, a change must be received by the receptors.

Insulin hormone

It instructs different body parts to take the excess blood/glucose.

Glucagon

It instructs the liver to break down its glycogen reserves and convert it to glucose and release it to the bloodstream.

Glycogen

the stored energy in humans/animals.

decreases

The levels of GnRH and LH in the blood _________ because of the negative feedback effect.

Deficiency

It occurs when the cells are not getting the necessary substances.

Toxicity

It occurs when the cells are getting poisonous and unnecessary substances. This is detrimental to overall health.

Adrenaline

hormone that increases heart rate / blood pressure

Adrenaline

fight or flight response hormone

Cortisol

primary stress hormone which can increase blood sugar
