HBS - lymphatic & immune system

Pathogen

A disease-causing organism.

Prions

Non-living proteins that infect through contamination, and medications can slow down their effects.

Viruses

Non-living entities that infect through contact or bodily fluids, destroying host cells. Vaccines can build acquired immunity.

Bacteria

Living organisms that infect through orifices, wounds, contamination, or contact. Antibiotics, hygiene, and vaccinations are used to combat them.

Orifice

Openings such as the nose, eyes, and mouth.

Protists

Living organisms that infect through contaminated feces. Antiprotozoal medications are used to treat them.

Fungi

Living organisms that infect when their spores are inhaled or land on a host. Antifungal medications are used to combat them.

Helminths

Living worms that can infect through contamination or through infected insects. Deworming medications are used to treat them.

Mucus

Substance that traps pathogens in the body, which can be swallowed and killed by stomach acid or expelled through orifices.

Epidermis

The top layer of the skin that provides a barrier, produces new skin cells, and gives color.

Dermis

The middle layer of the skin that contains collagen, produces oil and sweat, and houses blood vessels and nerve endings.

Subcutaneous fatty tissue

The bottom layer of the skin that provides fat and cushioning, protects bones, and helps regulate body temperature.

Sepsis

The body's immune system overreacting to an infection, causing inflammation.

Severe sepsis

Organs in the body malfunction, blood pressure drops, and inflammation persists.

Septic shock

Extremely low blood pressure that does not respond to IV fluids.

Lymph nodes

Small lumps of tissues that contain white blood cells to fight infections.

Lymph

Fluid in the body primarily composed of white blood cells.

Lymphatic system

Maintains fluids, absorbs fats, protects from pathogens, and transports/removes waste from the fluid.

Immune system

Utilizes organs from other body systems to protect the body and fights anything it doesn't recognize.

Platelets

Aid in blood clotting.

Red blood cells

Rich in hemoglobin, they transport oxygen throughout the body.

White blood cells

Active in immune response, including lymphocytes, monocytes, etc.

Innate immunity

Defense mechanisms that you are born with.

Acquired immunity

Defense mechanisms acquired throughout life.

B-cells

Mature in bone marrow and produce antibodies.

Antibodies

Produced by B-cells to impair pathogens.

Prodromal

Early signs of symptoms.

Convalesce

Gradual recovery after health has decreased.

T-cells

Type of white blood cell that recognizes and attacks pathogens.

Virus attacking host cell
