This is a cell signaling factor that travels through the blood and can signal to target cells in multiple organs simultaneously.

What is a hormone?

100

This is the structure that delivers the ovulated egg to the uterus.

What are the uterine tubes (or fallopian tubes)?

100

These are the small tubules where spermatogenesis occurs.

What are the seminiferous tubules?

100

This chamber of the heart has the thickest walls.

What is the left ventricle?

100

These are the leakiest type of small vessel.

What are sinusoids?

200

This is a hormone that is released by the posterior pituitary in response to high blood osmolarity.

What is ADH?

200

This is the thickest layer of the uterine wall.

What is the myometrium?

200

This is the serous membrane that surrounds the testes.

What is the tunica vaginalis?

200

This type of valve closes when ventricular systole occurs.

What are AV (atrioventricular) valves?

200

This is a plasma protein involved in the clotting process.

What is fibrinogen?

300

These are hormones released by the medulla of the adrenal gland.

What are catecholamines? (or what are epinephrine and norepinephrine?)

300

This structure releases large amount of progesterone during the luteal phase.

What is the corpus luteum?

300

This muscle contracts to elevate the testes.

What is the cremaster muscle?

300

This is a phase of the cardiac cycle where all valves are closed and pressure inside the ventricle is building.

What is the isovolumetric contraction phase?

300
This is a measure of how much blood is pumped out of the heart over the course of a minute.

What is cardiac output?

400
This is the enzyme that breaks down cAMP into inactive AMP.

What is PDE (phosphodiesterase)? 

400

A spike in this hormone triggers ovulation.

What is LH?

400

These cells secrete testosterone in the testes.

What are interstitial endocrine cells?

400

This is the main pacemaker of the heart.

What is the SA (sinoatrial) node?

400

This vessel that is part of the coronary circulation returns blood to the right atrium.

What is the coronary sinus?

500

These are non-lipid based hormones that bind to intracellular receptors.

What are the thyroid hormones?

500

This phase of the uterine cycle aligns with the luteal phase of the ovarian cycle.

What is the secratory phase?

500
This hormone stimulates the activity of nurse cells.

What is FSH?

500

The rapid entry of this ion is responsible for the depolarization of cardiac contractile cells. 

What is Na+ (sodium)?

500

This hormone is released by the heart when blood pressure is too high.

What are the natriuretic peptides (ANP and BNP)?
