blood flow

Question 1

name the type of circulation in the circulatory system
- define it also-

Answer 1

double circulation
- blood travels through the heart twice during 1 circuit of the body
- (travels through the pulmonary circuit and systemic circuit simultaneously)

Question 2

2 circuits in the system

Answer 2

-pulmonary circuit
-systemic circuit

Question 3

what is the pulmonary circuit

Answer 3

blood travels from the right ventricle of the heart to the lungs through the pulmonary artery

Question 4

environment of the pulmonary circuit

Answer 4

• blood is carried under low pressure

1. ideal as the blood moves slowly through the pulmonary capillaries
   - ensuring maximum gas exchange
2. ideal as the blood has less distance to travel from the heart, so less pressure is needed/ required

Question 5

environment of the systemic circuit

what type of pressure
benefits
why its nessesary

Answer 5

blood is pumped under high pressure

• ideal to ensure all **organs and tissues recieve sufficient metabolites **
• ensures waste is transported out of body quickly

high pressure allows blood to move faster down the aorta and reach the organs faster
the high pressure is nessesary as blood travels a further distance

Question 6

how is the systemic circuit adapted for its function

Answer 6

arteries (aorta) has a thicker muscular wall of the left ventricle

Question 7

what are metabolites

Answer 7

anything needed for respiration or growth

Question 8

cronological order of blood flow in a double circulation
