What are lungs?
Most vital organ in your body
What is a heart?
Inner tissue lining in the heart ventricles, atrium, valves, etc
What is endocardium?
located on the left side of your chest and positioned in the middle
Where is the heart located?
Brings deoxygenated blood back from upper body to right atrium
What is Superior Vena Cava?
They wrap around the outside of the heart on the myocardium (muscular tissue of the heart)
what are coronary arteries?
Flaps and prevent backward blood flow
What are valves?
The hearts muscular tissue
What is myocardium?
heart beats at around 60-100 beats per minute
What is average bpm for adults in resting state?
Brings deoxygenated blood back from lower body to right atrium
What is inferior vena cava?
Generally have more muscle around them so the blood can be pumped to a further distance
What are ventricles?
Main task to maintain flow
What is right/left atrium?
Protects myocardium and contains regeneration cells for repair
What is epicardium?
Bronchioles
What is the smallest branch of lungs?
Bring deoxygenated blood back to the right atrium
what are cardiac veins?
transport nutrients, oxygen, and waste products to and from the tissue
what are capillary veins?
pumps deoxygenated blood to the lungs to get oxygenated
What is right ventricle?
Protection and lubrication
What is pericardial cavity?
the Aorta
What is the largest branch of the artery?
Transfer oxygenated blood from the lungs to the left atrium in the heart which eventually gets pumped throughout the body
What are pulmonary veins?
regulation of blood glucose levels
what is a negative feedback loop
travel towards the heart generally carry deoxygenated blood
what are veins?
Tough outer layer & Connective tissue
What is fibrous pericardium?
