Homeostasis Exam Questions With Complete Solutions
Acidosis Correct Answer When blood pH becomes too low
(below ~7.4)
Alkalosis Correct Answer When blood pH becomes too high
(above ~7.4)
Alveoli Correct Answer Small sacs that come in clusters, are
surrounded by a network of capillaries, and allow for efficient
diffusion of gas between the lungs and the bloodstream
Antidiuretic Hormone (ADH)/Vasopressin Correct Answer
Causes more aquaporins to open so more H20 can be reabsorbed
into the blood
Aorta Correct Answer Artery through which blood exits the
heart and flows to the rest of the body
Aquaporin Correct Answer Special kind of protein channel
used in osmosis
Arteries Correct Answer Carry blood away from the heart
- Thicker, more muscular walls
- Higher blood pressure
Bowman's Capsule Correct Answer Cup-like structure in
which the blood filtrate collects
Bronchioles Correct Answer Branches off the bronchi which
transport air to alveoli
, Bronchus Correct Answer Air passages that diverge from the
trachea
Capillaries Correct Answer Thin walled hassles where gasses,
nutrients, and waste gets exchanged between body tissues and
the blood
- Direct contact with calls
- Site of diffusion/exchange between blood + tissue
- Very small, about the diameter of a blood cell
- Everywhere!
Collecting Duct Correct Answer This is where vasopressin
(AKA ADH) controls the number of aquaporin channels
available for water to be reabsorbed back into the blood
Compare and contrast temperature regulation in ectotherms and
endotherms Correct Answer Ectotherms are "cold-blooded"
organisms which have body heat that fluctuates with the
environment. Ectotherms regulate their temperature through
behavior (snakes go on hot rocks to warm). These include most
reptiles and amphibians. They have low metabolic rates (don't
produce much heat, don't have to eat much). Endotherms are
"warm-blooded" organisms which have body heat that is
maintained through homeostasis. Most birds and mammals are
endotherms. Heat is a byproduct of high metabolism, so they
have to eat a lot. They can survive in colder temperatures.
Describe a condition that can lead to blood acidosis and a
condition that can lead to blood alkalosis Correct Answer
Diabetic ketoacidosis occurs when your body produces high
Acidosis Correct Answer When blood pH becomes too low
(below ~7.4)

(above ~7.4)
