Cardio - Heart Anatomy 1 Flashcards
What are the four main organs in the cardiovascular system?
Heart, arteries, capillaries, lymphatics/veins
What are the organs in the vascular system made up of?
Vascular tissue
What is vascular tissue made of?
epithelial cells and muscle cells (cardiac muscle - for heart, smooth muscle for lining)
This is a closed supply and drainage system - a continuous loop
Blood vascular system
This is an open entry drainage system - a one way system
Lymphatic system
What are the 2 circulations in the body?
Pulmonary and systemic circulation
These are the only supply path of the cardiovascular system - supply blood to important structures in the body
Arteries
These are situated to avoid damage
Major arteries
What is the exchange network of the body?
Capillaries
What are the 3 types of capillaries?
Continuous, Fenestrated, Sinusoidal
categorised based on degree of permeability/leakiness
What is the drainage organ of the body?
Veins/lymphatics
Why is movement of blood under veins slow?
Because it’s under low pressure and a much larger cross-sectional area
What are the 3 pathways for drainage?
Deep veins, superficial veins, lymphatics
This could also be referring to cardiac circulation - where the 3 main paths for drainage in the veins is through the: coronary sinus, great cardiac vein and small cardiac vein
What shape is the heart?
Blunt cone shaped, with an apex and a base
Where is the PMI?
Between the 5th and 6th rib - 5th intercostal space
