QUESTIONS WITH DETAILED VERIFIED ANSWERS
(100% CORRECT ANSWERS) / ALREADY GRADED A+
What does the endocrine system consist of? - ans -Pituitary, thyroid, parathyroid,
adrenal, & pineal glands
What is the function of the endocrine system? - ans -secretes hormones into
blood.
What does the immune system consist of? - ans -lymphatic system (lymph nodes),
spleen, tonsils, thymus, and bone marrow
What is the function of the immune system? - ans -Defense against foreign
invaders (microbes, bacteria, viruses)
What does the nervous system consist of? - ans -central nervous system,
peripheral nervous system, brain, and spinal cord
What is the function of the nervous system? - ans -Coordination of body function
through electrical signals
What does the musculoskeletal system consist of? - ans -skeletal muscles and
bone
What are the functions of the skeletal system? - ans -Support and movement
What does the reproductive system consist of? - ans -Testes, penis, ovaries,
vagina, and breasts. (produce off spring)
What is homeostasis? - ans -Maintaining a stable internal environment that your
body operates best at.
What are the two types of homeostasis feedback? - ans -Negative (calm down)
and positive (external change)
,What is negative feedback in homeostasis? - ans -loops occur in your body
through its own internal controller for maintaining temperature, pH, hormone
levels, blood sugar and other internal variable levels at homeostasis (calm down)
homeostasis positive feedback - ans -A loop in which the output increases its own
production. (child birth, lactation, blood vessel damage) (don't calm down)
What are the four steps in the homeostasis feedback mechanism?
- ans -1) Senses the parameter using sensor / receptor (needs stimulus)
2) Compares the parameter to the normal operating value (set-point)
3) Sensor produces an output signal to a control center
4) Output signal from the control centre then activates the effector to bring the
parameter closer to the set-point
How do the lungs maintain homeostasis? - ans -Blood picks up oxygen and
releases carbon dioxide
How does the gastrointestinal tract maintain homeostasis? - ans -Extraction of
nutrients
How does the liver maintain homeostasis? - ans -Changes the chemical
compositions of many of the substances absorbed by the GI to a more usable
form
How do the kidneys maintain homeostasis? - ans -Filtration unit, For electrolytes
and fluid balance
How does the musculoskeletal system maintain homeostasis? - ans -Locomotion,
muscle contraction
How does the nervous system maintain homeostasis? - ans -Autonomic system
operates at a subconscious level to control many body functions (ex. heart rate)
How does the hormonal system maintain homeostasis? - ans -To help regulate
cellular function
, What are the 3 region names of an anterior view of the body? - ans -Cephalic
(head), cervical (neck), and trunk (chest, abdomen, and pelvis
What are the two sections of the posterior view of the body? - ans -Upper limb
(shoulder to finger tips) and lower limb (hip to feet)
proximal vs distal - ans -close vs far
What are the 3 general cavities of our body? - ans -Cranial cavity (Brain);
Thoracic cavity (Lungs & heart); Abdominopelvic cavity (Gastrointestinal tract,
liver, kidneys,spleen & female reproductive tract)
What is the extracellular compartment made up of? - ans -Interstitial fluid
(interstitium), Plasma, and Transcellular fluid
Total body mass for females? for males? - ans -Female - 45% solids and 55%
fluids; Male - 40% solids and 60% fluids
How is total body fluid divided? - ans -2/3 intracellular and 1/3 extracellular
What is extracellular fluid (ECF) divided into? - ans -80% interstitial fluid and 20%
plasma
In your body what had the LEAST amount of fluid? - ans -plasma
What percent of our body is water? - ans -60% (42 liters)
What are the 3 main parts a cell is divided into? - ans -plasma, cytoplasm, and
nucleus
Are the things you eat and drink part of your body? - ans -No
What does the circulatory system consist of? - ans -The circulatory system is an
organ system that consists of the heart, the blood vessels (arteries, veins, and
capillaries) lymph vessel, and the blood.
