Human Anatomy and Physiology Quiz

Lymphatic System and Immunity

• Leukocytosis is often accompanied by an infection
• The spleen removes worn out blood cells from circulation
• The right arm may become oedematous if lymphatic vessels and nodes are removed from the right axillary region

Tonsillectomy and Thymus Gland

• Tonsillectomy is the term used for removal of palatine tonsils
• The thymus gland is responsible for processing and maturation of T lymphocytes

Lymphatic System Structures

• Lacteals are located within intestinal villi
• Lymph nodes are populated with lymphocytes and macrophages
• Lymphatic capillaries absorb tissue fluid and transport it towards the heart

Immunity and Allergies

• Band T cells are lymphocytes
• Anaphylaxis is the name of a severe hypersensitivity reaction
• If you had measles as a child, you have naturally acquired active immunity
• An allergen is called an antigen
• Band T cells represent specific immunity

Infection and Inflammation

• Redness, heat, swelling, and pain are indicative of infection/inflammation
• Macrophages engulf the pathogen to achieve antigen presentation
• Killer T cells destroy pathogens by punching holes in their cell membranes
• Memory T cells remember if the antigen is presented later in the future

Immune-related Conditions

• Infections are most common in people with AIDS
• Immunization is the term used for dead pathogens to stimulate antibody production
• Antipyretic drugs lower a fever
