Cardio Physiology Part 1 Flashcards
What are the three principal components of the cardiovascular system?
- Heart
- Blood Vessels
- Blood
What are the formed elements in blood?
- Red Blood Cells
- Platelets
- White Blood Cells
What are the two divisions in White Blood Cells or leukocytes?
- Granulocytes
- Agranulocytes
What are the three types of granulocytes?
- Neutrophils
- Eosinophils
- Basophils
What are the two types of agranulocytes?
- Lymphocyte
- Monocyte
This carries blood cells, proteins, nutrients, metabolic wastes, and other molecules transported around the body
Plasma
This is a physiological mechanism that stops bleeding
Hemostasis
What is the 3-step process of hemostasis?
- Vascular spasm
- Platelet plug formation
- Blood coagulation
This results from damage to the blood vessel. The damaged tissue secretes factors that cause contraction.
Vascular spasm
Vessels __________ to minimize blood loss
Constrict
This forms around the site of damage to decrease blood loss and maintain blood pressure.
Platelet Plug Formation
This occurs around the platelet plug, providing protection or blood clots.
Blood coagulation
These are secreted in inactive forms into the blood then becomes activated during cascade
Clotting factors
Where are clotting factors produced?
Liver
Plasma without clotting factors
Serum
When there’s collagen, activation of clotting factors
Intrinsic pathway
What is the common pathway for both intrinsic and extrinsic pathways?
Factor IX — Christmas Factor (Primary Thromboplastin Component)
Both pathways activate __________ to __________
Thrombin; Prothrombin
