Blood vesselsCarry blood Away

from heart to parts of the body

Tiny vesselsAllow exchange

between body cells and blood

Veins Carry blood back to heart from body cells

Pulmonary Circulation

Systemic Circulation

Through pulmonary arteries, capillaries, and veins

Flow of blood from heart to all parts of the body back to heart

Atherosclerosis Due to cholesterol build up in vessels

Major cause of heart disease

High Blood Pressure Also known as hypertension

Increased chance of heart attack or heart failure

Heart Attack When heart muscle cells die

Part of heart muscle damaged

Heart Failure Heart cannot pump enough blood to meet body’s demand

Lymphatic System

Lymph

Lymph Capillaries

Group of organs that collects excess fluids

Returns fluids to the blood

Fluid absorbed into lymph system

Vessels that lymph travels through

Bone Marrow

Lymph Nodes

Where red and white blood cells are made (lymphocytes)

Small, bean-shapedRemove pathogens

and dead cells

Thymus

Spleen

Produces T cells to fight infection

Largest lymphatic organ

Stores and produces lymphocytes

Tonsils Found in nasal cavity and back of mouth

Help defend against infection

Strep Throat

Respiration

Two parts of respiration

Process by which gets and uses oxygen

Also, releasing of carbon dioxide and water

1. Breathing2. Cellular Respiration

Chemical reaction that releases energy from food

Respiratory System Group of organs that take in oxygen

Get rid of carbon dioxide

Nose

Pharynx

Larynx

Main passageway in and out of the respiratory system

After nose“Throat”

Part of throat that contains the vocal chords

Trachea

Bronchi

“Windpipe”Guarded by the

larynxSplits into two

branches

Connect to the lungsBranches into

bronchioles

Alveoli Thousands of tiny sacs in the lungs

Exchange of gases occur here

Branched from bronchioles

Diaphragm Dome muscle beneath the lungs

Controls breathing

Asthma Causes bronchioles to narrow

Can be triggered by irritants such as dust or pollen
