Cardiovascular system

Question 1

Cardiovascular system: components

Answer 1

• Heart
• Arteries and arterioles
• Veins and venules
• Blood
• Capillaries

Question 2

What is the cardiovascular system responsible for?

Answer 2

• Transporting substances to and from all body cells via blood flow
• Also has a role in disease resistance and regulating pH

Question 3

Heart: components

Answer 3

• 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

Question 4

Heart: Function

Answer 4

1. Through a complex symptoms of contractions, the heart acts as a pump, constantly propelling blood through the blood vessels in the whole body
2. Coronary arteries deliver blood to the heart muscle
3. Coronary veins drain blood from the heart muscle

Question 5

Arteries and arterioles: Components

Answer 5

• 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

Question 6

Flows away from heart (artery)

Answer 6

• Arterioles

Question 7

Flows towards heart (artery)

Answer 7

venule

Question 8

Arteries and arterioles: Function

Answer 8

1. Arteries carry blood away from the heart and distribute it to other organs of the body
2. The flow of blood carrying nutrients and oxygen is regulated by arterioles (small arteries)

Question 9

Veins and venules: Components

Answer 9

• 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

Question 10

Veins and venules functions

Answer 10

• 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

Question 11

Blood: Components

Answer 11

• Red blood cell
• White blood cells

Question 12

Red blood cell?

Answer 12

Platelets

Question 13

White blood cells?

Answer 13

• Monocyte
• Lymphocyte
• Eosinophil
• Basophil
• Neutrophil

Question 14

Blood: Functions

Answer 14

1. Flows through heart, veins, and arteries transporting water, blood cells, and needed substances to body cells, and waste products away from body cells
2. Regulates pH of body fluids
3. Protects the body through blood clotting, and against disease through phagocytosis, production of natural antibiotics and antibodies.

Question 15

Capillaries: Components

Answer 15

• Arteriole
• Capillary
• Venule
• Blood: plasma, red blood cell

Question 16

Capillaries: Function

Answer 16

• Capillaries provide a site for the exchange of nutrients, respiratory gases and cellular waste products between the blood and body cells
