100

This is classified as a secondary endocrine organ. (Multiple answers possible)

Heart, Kidneys, Stomach/Intestines, etc.

100

These are the most numerous leukocytes in the blood.

Neutrophils

100

The AV Node transmits an electrical signal to this feature in the Intrinsic Conduction System.

AV Bundle

100

This layer of the blood vessel wall can produce vasoconstriction.

Tunica media

200

This is one of two Posterior Pituitary hormones. 

Oxytocin or Antidiuretic Hormone/Vasopressin

200

This first step of this process is a vascular spasm, which limits the loss of blood through a wound in the tissue.

Hemostasis

200

This produces the first heart sound ("lub").

Atrioventricular valves close

200

This type of capillary is found in the kidneys and intestines only. It is characterized by holes large enough for smaller proteins to be filtered. 

Fenestrated

300

Many protein hormones use this as a second messenger, which transmits and amplifies the message  within the target cell.

cAMP (cyclic AMP)

300

When a blood sample is NOT treated with anticoagulants, this is the fluid that floats to the top of the tube.

Serum

300

This happens at feature D on the graph.

Atrioventricular valves OPEN (no sound)

300

These circular muscles shunt blood directly through the capillary bed rather than allowing blood to exchange substances with the tissues in all parts of the capillary bed.

Precapillary sphincters

400

An autoimmune attack of the thyroid gland would result in an increase in which anterior pituitary hormone?

Thyroid Stimulating Hormone

400

Most plasma proteins are synthesized by this organ.

Liver

400

This is the volume of blood in the ventricle before systole.

End Diastolic Volume (EDV)

400

This is the only hormone discussed in class that DECREASES blood pressure.

Atrial Natriuretic Peptide

500

In the HPA Axis, this hormone is released from the hypothalamus.

Corticotropin Releasing Hormone

500

Platelets are pinched off from these giant multinucleated cells in the bone marrow.

Megakaryocytes

500

This neurotransmitter induces the SA Node pacemaker cells to depolarize more quickly.

Norepinephrine

500

In this automatic response, a shift in blood pressure is detected by receptors -> inform the medulla oblongata -> activates SNS or PSNS to increase or decrease heart rate
