Essential Question How do animal systems interact to defend the body? Standard B.10A - describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals PG 124

what’s in red blood cells white blood cells platelets plasma carbon dioxide digested food waste (urea) hormones oxygen

Red Blood Cells contain hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. can change shape to an amazing extent, without breaking, as it squeezes single file through the capillaries. a biconcave disc that is round and flat without a nucleus

INTERACTION: Maintaining Homeostasis Balancing glucose levels in blood pancreas insulin liver takes up glucose for storage cells take up glucose from blood liver releases glucose to blood depress appetite stimulate hunger glucagon

ILLNESS Integumentary (1 st line of defense) Immune (2 nd line of defense) Circulatory SYSTEMS INVOLVED

INTEGUMENTARY SYSTEM Main Parts: – Skin – Hair – Nails – Sweat and Oil glands

INTEGUMENTARY SYSTEM Main Functions: – Holds in water – Keeps out foreign objects – Helps control body temperature

Functions of the Integumentary System (skin) Protection – First line of defense against Bacteria Viruses – Protects underlying structures from Ultraviolet (UV) radiation Dehydration Body temperature regulation – If too hot Dermal blood vessels dilate Vessels carry more blood to surface so heat can escape – If too cold Dermal blood vessels constrict Prevents heat from escaping

Vitamin D production – Needed for calcium absorption Sensation – Sensory receptors (nerves) Excretion – Small amounts of waste products are lost through perspiration (sweat) Functions of the Integumentary System (cont.)

IMMUNE SYSTEM Main Parts: – Antibodies (protective proteins) – T-cells (WBC) – B-cells (WBC)

IMMUNE SYSTEM Main Functions: – B-cells produce antibodies that attack pathogens (foreign invaders) in the blood – T-cells attack invaded body cells – Each B-cell, T-cell, and antibody is specific to what it attacks

Vaccinations Immune system exposed to harmless version of pathogen – stimulates B cell system to produce antibodies to pathogen “active immunity” – rapid response on future exposure – creates immunity without getting disease! Most successful against viruses

Immune System Malfunctions Auto-immune diseases – immune system attacks own molecules & cells lupus rheumatoid arthritis diabetes multiple sclerosis Allergies – over-reaction to environmental antigens allergens = proteins on pollen, dust mites, in animal saliva stimulates release of histamine

CIRCULATORY SYSTEM RECAP Main Parts: – Blood vessels – Heart – Red & White blood cells (includes B- and T-cells)

CIRCULATORY SYSTEM Main Functions: – Transports antibodies & white blood cells (Add Video Clip of Macrophage) – Transports toxins and waste products to be removed

ALLERGIC REACTIONS are your body overreacting to harmless substances.

MID-LESSON DEBRIEF: Explain how the three systems work together to defend the body against illness. The integumentary system is the first line of defense, keeping out most invaders. The immune system kicks in when something gets past the integumentary system, and uses the circulatory system to move within the body.
