Key ideas to know
Start with the relationships between ideas. Then close the notes and explain each one from memory.
- 01
Anatomy and physiology accounts for 18 of the 44 scored Science items listed by ATI.
- 02
The cardiovascular system carries gases, nutrients, hormones, heat, and wastes.
- 03
The respiratory system ventilates alveoli and exchanges oxygen and carbon dioxide with blood.
- 04
The digestive system breaks material into absorbable units and moves them into blood or lymph.
- 05
The kidneys filter plasma, return needed substances, secrete selected solutes, and regulate water and electrolytes.
- 06
The nervous system sends rapid electrical and chemical signals.
- 07
The endocrine system sends hormones through blood to cells with matching receptors.
- 08
Negative feedback reduces a departure from a regulated range.

NOT QUITE
→Veins always carry low-oxygen blood
USE THIS INSTEAD
Pulmonary veins carry oxygenated blood; direction toward the heart defines a vein.
NOT QUITE
→Every cell responds to every hormone
USE THIS INSTEAD
A cell requires a matching receptor.
Flashcards
Answer before opening each card. The effort to retrieve is part of the learning.
1Which chamber sends blood to the lungs?Show answer ＋
The right ventricle.
2Where does most gas exchange occur?Show answer ＋
Across the alveolar-capillary membrane.
3Where does most nutrient absorption occur?Show answer ＋
The small intestine.
4What is the functional unit of the kidney?Show answer ＋
The nephron.
5What is a synapse?Show answer ＋
A junction where one cell signals another.
6How do hormones reach target cells?Show answer ＋
They travel through blood and bind matching receptors.
7What does insulin generally do to blood glucose?Show answer ＋
Promotes glucose uptake and storage, lowering blood glucose.
8What does negative feedback do?Show answer ＋
Opposes a departure from a regulated range.
Explain it in your own words
Use the answer as a check after you have written or spoken your response.
01Trace blood from the right ventricle to the left atrium.
Pulmonary valve, pulmonary trunk and arteries, lung capillaries, pulmonary veins, then left atrium.
02Why are alveolar walls thin?
A short diffusion distance permits faster gas exchange.
03How does the small intestine increase absorptive area?
Folds, villi, and microvilli expand the surface available for absorption.
04How can antidiuretic hormone affect urine?
It raises water reabsorption in collecting ducts, producing a smaller volume of more concentrated urine.
05Why can one hormone affect some cells but not others?
Only target cells with the matching receptor respond.
