Homeostasis
The ability of an organism to maintain a stable internal environment.
What is homeostasis?
Part of the body produces blood cells.
What is bone/bone marrow?
The urinary system is responsible for removing ____ waste in the human body.
What is liquid?
What are seeing, hearing, tasting, smelling, and feeling?
The production of blood cells is called
a. Hematoma
b. Hematopoiesis
c. Hematology
d. Hematologist
Give one disruption to homeostasis
What are
1. sensors fail (don’t detect changes)
2. targets do not receive messages (nerve issues)
3. injury (overwhelm homeostatic controls)
4. illness (viruses or bacteria)?
Give two functions of blood
Transporting gases (oxygen & carbon dioxide)
Transporting waste products
Transporting nutrients
Helping remove toxins from the body
An INCREASE in one action causes an INCREASE in another, for example when you are bleeding. Your body produces more and more platelets until your body stops bleeding.
What is positive feedback?
Give two functions of water
Transport
Structural support for molecules
Participates in metabolic reactions
Solvent
Lubricant & shock absorber
Body temperature regulation
Maintains blood volume & blood pressure
Tiny structures in the kidney that its main job is filtration.
What are nephons?
Three aspects of the body that must be maintained in order to achieve homeostasis.
What are pH, Body Temperature, oxygen level, blood volume, and Blood Sugar?
Another name for RBC or red blood cells
What are the erythrocytes?
The breathing mechanism during exercise when your CO2 increases and your O2 decreases, and your body breathes faster, is an example of
What is negative feedback?
Give two parts of the nervous system.
What are the central nervous system and peripheral nervous system?
A change in the environment that causes response.
What is stimulus?
Give 3 body systems that are part of the thermoregulation.
What is Muscular, Integumentary(skin), Respiratory, Circulatory, Nervous (hypothalamus in brain), Endocrine (hormones, feedback)
Part of the blood that is responsible for blood clotting
What is platelets/thrombocytes?
Four main organs of the urinary system
What are kidneys, ureters, bladder, and urethra?
Compare and contrast. Extracellular fluid and intracellular fluid.
Extracellular fluid is body fluid outside the cell, and Intracellular fluid is body fluid inside the cell. Both are body fluids.
Give three mechanisms of homeostasis when it is cold
What are vasoconstriction, shivering, piloerection, and curling?
If homeostasis is not achieved this occurs...
What is death!
Identify the parts of the blood in terms of its volume, starting with the most.
What are plasma, red blood cells, and white blood cells/platelets?
Three processes of urine formation
What are filtration, reabsorption, and secretion?
Give an explanation of the basic function of the nervous system using an example.
What are sensory input, integration, and motor output?
Compare and contrast. Specialized cell and stem cell.
Specialized cells are cells that have specific functions, stem cells are cells that can change into different type of cells. Both are cells.
