Agenda

- Intro notes to the cardiovascular system

- Intro to CV system questions (notes & textbook)

Prologue… Remember… Always label and refer to anatomical directions based on the patient’s POV (point of view)

Examples:

Cardio -

Vascular -CV system functions:

1. Thermoregulation 2. Deliver oxygen, nutrients & hormones to cells3. Remove carbon dioxide & other waste from cells4. Blood clotting5. Fight infection

AKA Circulatory system AKA Vascular system (vascular tissue)

heart

vessels/ tissue that lets blood (or sap) flow

(Blood circulates throughout this system)

5 Key parts of the cardiovascular system

1. Heart2. Blood3. Veins4. Arteries5. Capillaries

The Mammalian Heart- 4 chambers & 2 loop system- Allows faster transport of blood at higher pressure- Fuels the high metabolism needed for endothermy

- Endothermy - “warm blooded”, organism can regulate its body temp. via internal metabolism

● reptiles/amphibians = 3 chambers, ectotherms● fish = 2 chambers, poikilotherms)

Human Blood Cells- 7 Types of blood cells

can you name any?

Functions of our different blood cells:

1. Carry O2 to cells2. Carry CO2 away from cells3. Fight infection4. Assist in wound healing (clotting)

5 types of blood cells are white blood cells

Vascular TissuesThis tissue circulates blood and lymphatic fluids around the body

3 main components:1. Veins - Deoxygenated blood to heart

2. Arteries - Oxygenated blood away from heart

3. Capillaries - Transfer between cells and larger blood vessels

Your Pulse

Each pulse you feel is a surge of blood, pushed through your blood vessels by each beat of your heart. Your heart is doing a tremendous amount of work!

How does this relate to chest compressions performed in CPR?

Press your index and middle finger into your neck, underneath your jaw, towards the back

OR Press these fingers into your wrist, on the thumb side of the central ligaments

A Hidden Player...The lungs are part of the respiratory system…

… but they play an important role in the cardiovascular system

Can you explain how the lungs fit into this system?
