BIOL 118 Blood, Lymphatic, and Immune System Thursday PF Session

Hemostasis

100

Hemostasis means stopping this when a blood vessel is hurt

Bleeding

200

3 major events in hemostasis

Vascular spasm, platelet plug formation, and coagulation

300

During vascular spasm, this type of muscle contracts in the blood vessel wall

Smooth muscle

400

This protein connects exposed collagen and platelets during platelet plug formation

von Willebrand factor (vWF)

500

Coagulation aims to convert this protein into sticky fibrin

Fibrinogen

Lymphatic System

100

Lymph reenters the bloodstream through this vein

Subclavian vein

200

Unlike blood, lymph typically does not contain this 

Red blood cells

300

Which vessels enter a lymph node, and which vessels exit a lymph node?

Afferent vessels enter, and efferent vessels exit

400

The lymphatic system is low-pressure and does not have this organ acting as a pump

Heart

500

These three things help move lymph through lymph vessels

Skeletal muscle contractions, breathing, and smooth muscle in large lymphatic vessels

Pathogens & Antigens

100

A microorganism that can cause disease

Pathogen

200

Substance capable of provoking an immune response

Antigen

300

This pathogen is made up of RNA or DNA and protein but is not a cell

Virus

400

This type of pathogen has a nucleoid region

Bacteria

500

Compared to viruses and bacteria, this type of pathogen is more complex

Parasite

Innate Immunity

100

Swelling, redness, heat, and pain are all symptoms of this response.

Inflammatory Response

200

Helper T cells release cytokines to activate these antibody-releasing cells.

B cells

300

A virus infects a cell. The infected cell releases this protein to help neighboring cells resist viral infection.

Interferon

400

NK cells and cytotoxic T cells both kill abnormal cells, but only these cells are part of innate immunity.

Natural Killer (NK) cells

500

Skin is damaged and bacteria enter the body. The first immune response comes from this branch of immunity.

Innate Immunity

Blood & Vessels

100

What molecule do your red blood cells carry the most

Oxygen (O²)

200

These proteins act as carriers, buffers, are involved in blood clotting, and more!

Plasma proteins

300

This hormone regulates platelet production and is produced primarily by the liver

Thrombopoietin (TPO)

400

Name the three components/layers of blood, and list them in decreasing order of quantity (1→3)

1. Plasma, 

2. Hematocrit

3. Buffy coat

500

This process is how red blood cells (erythrocytes) are produced

Erythropoiesis
