Cardiovascular system Flashcards
1
Q
Cardiovascular system: components
A
- Heart
- Arteries and arterioles
- Veins and venules
- Blood
- Capillaries
2
Q
What is the cardiovascular system responsible for?
A
- Transporting substances to and from all body cells via blood flow
- Also has a role in disease resistance and regulating pH
3
Q
Heart: components
A
- Aorta
- Left common carotid arterty
- Superior vena cava
- Pulmonary trunk
- Left pulmonary artery
- Left pulmonary veins
- Right pulmonary veins
- Right pulmonary arteries
- Right atrium
- Right ventricle
- Left atrium
- Left ventricle
- Inferior vena cava
- Tricuspid valve
- Aortic semilunar valve
- Bicuspid (mitral) valve
- Pulmonary semilunar valve
- Coronary artery
4
Q
Heart: Function
A
- Through a complex symptoms of contractions, the heart acts as a pump, constantly propelling blood through the blood vessels in the whole body
- Coronary arteries deliver blood to the heart muscle
- Coronary veins drain blood from the heart muscle
5
Q
Arteries and arterioles: Components
A
- Brachiocephalic trunk
- Left common carotid
- Aorta
- Thoracic aorta
- Abdominal aorta
- Right subclavian
- Right brachial
- Left axillary
- Smooth muscle
- Precapillary sphincters
- Capillaries
- Venule
- Arteriole
- Right common carotid
- Left femoral
- Left gastric
- Common hepatic
- Right renal
- Left renal
- Left common illiac
6
Q
Flows away from heart (artery)
A
- Arterioles
7
Q
Flows towards heart (artery)
A
venule
8
Q
Arteries and arterioles: Function
A
- Arteries carry blood away from the heart and distribute it to other organs of the body
- The flow of blood carrying nutrients and oxygen is regulated by arterioles (small arteries)
9
Q
Veins and venules: Components
A
- Coronary sinus
- Right axillary
- Inferior vena cava
- Right cephalic
- Right hepatic
- Superior vena cava
- pulmonary trunk
- Right internal jugular
- Right external jugular
- Right subclavian
- Right brachiocephalic
- Hepatic portal
- Left renal
- Left common iliac
- Left external iliac
- Left femoral
- Left great saphenous
- Venule (to heart)
- Arteriole (from heart)
- Capillary
10
Q
Veins and venules functions
A
- Veins and venules (little veins) recieve blood from capillaries and then empty into the veins of the body to transport carbon dioxide and wastes away from the body’s cells
11
Q
Blood: Components
A
- Red blood cell
- White blood cells
12
Q
Red blood cell?
A
Platelets
13
Q
White blood cells?
A
- Monocyte
- Lymphocyte
- Eosinophil
- Basophil
- Neutrophil
14
Q
Blood: Functions
A
- Flows through heart, veins, and arteries transporting water, blood cells, and needed substances to body cells, and waste products away from body cells
- Regulates pH of body fluids
- Protects the body through blood clotting, and against disease through phagocytosis, production of natural antibiotics and antibodies.
15
Q
Capillaries: Components
A
- Arteriole
- Capillary
- Venule
- Blood: plasma, red blood cell
