Blood
Blood Pressure
Plasma
Connective TissueCarries gases,
nutrients, and waste through the body
Regulates body temperature
Force given off by blood onto the inside walls of arteries
Fluid part of bloodMostly water
Red Blood Cells
White Blood Cells
Main cells found in blood
Carries gas, nutrients, and waste through the body
Destroys pathogensCleans woundsDestroys body cells
that have died or are damaged
Platelets Pieces of larger cells
Found in marrowHelp with blood
clots
4 Types of Blood 1. A2. B3. AB4. O
Cardiovascular system
3 Types of Blood Vessels
Heart and blood vessels
ArteriesCapillariesVeins
Heart Cardiac muscleSize of fistAlmost center in your
chest cavity
Arteries
Capillaries
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
Flow of blood from heart to lungs back to heart
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
