Blood
What are the 3 interrelated components of the cardio vascular system?
Blood, Blood Vessels, & Heart
Blood
Is considered connective tissue
What are the 2 components of blood?
Plasma 55% / Formed Elements 45%
What is in the formed elements
Red blood cells
White blood cells
Platelets
What do blood cells do?
Carries oxygen to cells
What do White Blood cells do?
Immune response (leukocytes)
What do Platelets do?
Allows for blood to clot.
Formed blood cells are formed in the ____________
red bone marrow.
What are the 5 types of blood vessels? (in order of largest to smallest then smallest to largest)
Arteries Arterioles Capillaries Venules Veins
What do the Arteries do?
Move blood from the heart to the body.
What are Arterioles?
A very small, almost microscopic artery that delivers blood to capillaries.
What are capillaries?
A microscopic vessel that connect arteriole to venule
What do Venules do?
Receive blood from the capillaries
What do the Veins do?
Return blood to the heart.
What are the characteristics of the Artery?
Thicker walls
Take blood away from heart
No Valve
Arterioles are the smaller version
What are the characteristics of the Vein?
Thinner walls
Move blood towards the heart
Have Valves
Venules are the smaller version
Heart
Is a pump that provides the primary force to circulate blood.
Located in the center of the chest, deep to the sternum
Pericardium
A membrane that surrounds and protects the heart
What are the 4 chambers of the heart?
Right Atrium
Left Atrium
Right Ventricle
Left Ventricle
The heart is divided by the __________
Septum
What are the 2 circuits of blood flow?
Pulmonary
Systemic
What is the job of the systemic circuit?
To send blood to systems of body
What is the job of the pulmonary circuit?
To send blood to from heart to lungs to heart.
Functions of the Cardiovascular System
Transportation
Regulation
Protection
Transportation Function
Transports oxygen, hormones & nutrients to cells of the body.
Also transports carbon dioxide from the cells back to the lungs.
Regulation Function
Body temperature acting with the integumentary system.
Regulates the fluid levels in the body.
Protection Function
Clotting properties of blood help protect against excessive blood loss during injury.
White blood cells protect against disease in the body
What is the clinical connection of massage and the Cardiovascular System?
- Increases the fluidity of connective tissue.
- The oxygen-carrying capacity of blood is increased for a limited time after general massage.
- Can increase local circulation (blushing).
- Circulatory massage (Swedish) helps move fluids towards the heart.
Pathology: Anemia
Indicated
Cautions: When accompanying other disorders.
Pathology: Leukemia
Indicated
Cautions: High caution and the therapist should work with the healthcare team.
Pathology: DVT
Contraindicate
This is typically a bedridden person
Pathology: Varicose Veins
Indicated; Local
Cautions: Light work over veins, clients with varicose veins have higher risk for DVT.
Pathology: Atherosclerosis
Contraindicated, unless cleared by doctor.
Cautions: For those clients that have a serious heart condition.
Pathology: Heart Attack
Indicated
Cautions: Gentle supportive work, 3 months post attack.
