Systems (Circulatory) Flashcards
What is the overall function?
- Transporting oxygen and nutrients everywhere
What makes up the circulatory system?
- Artery
- Vessels
- Capillaries
- Veins
Circulatory System Function: Arteries
- The heart pumps blood through arteries
Circulatory System Function: Vessels
- Arteries branch off into blood vessels
Circulatory System Function: Capillaries
- Small blood vessels are called capillaries, blood exchanges with tissues
Circulatory System Function: Veins
- After the exchange, blood flows into veins then back to the heart
What is blood made up of?
- Red and white blood cells, platelets, and plasma
Coronary Artery
- Blood vessels that provide blood to heart tissue
Diseases
- Coronary Artery Disease
- Heart Attack
Disease: Coronary Artery Disease
- When coronary arteries become partially blocked with plaque. Plaque buildup can be caused by bad genetics or poor lifestyle choices
Disease: Heart Attack
- When plaque builds up so nothing can get through anymore. The heart is no longer able to get the nutrients and oxygen it needs. Heart tissue begins to die
Organs Involved
- The heart. The hearts job is to pump blood so it can be transported everywhere
Blood
- Red blood cell membrane contain glycoproteins
- The glycoproteins are called RBC antigens
- RBC antigens help your immune system recognize RBCS as a part of your system
- There are two types of RBC antigens, A and B
- Your immune system can only tolerate your RBC antigen, meaning you must get the same type
Positive or Negative?
If you have an RH factor (protein found on the surface of red blood cells) your blood will be positive, if not it will be negative
Cardiac Output
The volume of blood pumped by the heart (mL)
Blood Pressure (2 types)
Systolic Pressure: When pressure in arteries reach max and the ventricles contract to push blood through
Diastolic Pressure: When pressure in arteries are at the lowest and the ventricles are not contracting
Pulse Rate
How many times your heart beats
