ATI TEAS 7 ELITE PREP 2026/2027 || TEAS EXAM REVIEW
|| VERIFIED QUESTIONS & ANSWERS || HIGH-YIELD STUDY
GUIDE || COMPLETE TEST BANK || GRADED A+
Path of blood flow through the heart - CORRECT ANSWER -
Unoxygenated blood from Inferior Vena Cava (lower extremities) / Superior
Vena Cava (upper extremities) → Right Atrium → Right Ventricle →
Pulmonary artery → Lungs for oxygenation → Pulmonary Vein → Left Atrium
→ Left Ventricle → Aorta → Upper and lower extremities through arteries
Cytoskeleton - CORRECT ANSWER -Cytoskeleton maintains cells shape,
anchors, organelles and assist with transport. Made up of Micro filament (actin)
is closer to the cell membrane; Intermediate filament is in the middle of the cell
and random; Microtubule branches out of the nucleus.
ADH - CORRECT ANSWER -Antidiuretic hormone (ADH), also known as
vasopressin, is produced in the hypothalamus and secreted by the pituitary
gland. It helps the kidneys control how much water the body loses through
urine. When ADH is released, the kidneys conserve water and produce more
concentrated urine.
Hypothalamus - CORRECT ANSWER -Releasing and Inhibiting
Hormones: Regulate the release of hormones from the pituitary gland.
Pituitary Gland - CORRECT ANSWER -Often referred to as the 'master
gland'.
Growth Hormone (GH) - CORRECT ANSWER -Stimulates growth and
cell reproduction.
Thyroid-Stimulating Hormone (TSH) - CORRECT ANSWER -Stimulates
the thyroid gland.
,Adrenocorticotropic Hormone (ACTH) - CORRECT ANSWER -Stimulates
the adrenal glands.
Luteinizing Hormone (LH) - CORRECT ANSWER -Regulates testosterone
and estrogen.
Follicle-Stimulating Hormone (FSH) - CORRECT ANSWER -Stimulates
ovarian follicle growth and sperm production.
Prolactin (PRL) - CORRECT ANSWER -Stimulates milk production.
Antidiuretic Hormone (ADH) - CORRECT ANSWER -Regulates water
balance in the body.
Oxytocin - CORRECT ANSWER -Stimulates uterine contractions during
childbirth and milk ejection during breastfeeding.
Thyroxine (T4) - CORRECT ANSWER -Regulates metabolism.
Triiodothyronine (T3) - CORRECT ANSWER -Also regulates metabolism
and is more active than T4.
Calcitonin - CORRECT ANSWER -Helps regulate calcium levels in the
blood.
Parathyroid Hormone (PTH) - CORRECT ANSWER -Regulates calcium
levels in the blood by increasing calcium release from bones and absorption in
the intestines.
, Cortisol - CORRECT ANSWER -Regulates metabolism, helps the body
respond to stress.
Aldosterone - CORRECT ANSWER -Regulates sodium and potassium
levels, and blood pressure.
Adrenaline (Epinephrine) - CORRECT ANSWER -Increases heart rate and
energy in response to stress.
Norepinephrine - CORRECT ANSWER -Works with adrenaline to regulate
the fight-or-flight response.
Insulin - CORRECT ANSWER -Lowers blood sugar levels by facilitating
glucose uptake into cells.
Glucagon - CORRECT ANSWER -Raises blood sugar levels by promoting
the release of glucose from the liver.
Estrogens - CORRECT ANSWER -Regulate the female reproductive
system and secondary sexual characteristics.
Progesterone - CORRECT ANSWER -Prepares the uterus for pregnancy
and regulates menstrual cycle.
Testosterone - CORRECT ANSWER -Regulates male reproductive
functions and secondary sexual characteristics.
Melatonin - CORRECT ANSWER -Regulates sleep-wake cycles and
seasonal biological rhythms.
