Flashcards in Structure Of The Heart Deck (18):
1

Vena Cava (top left)

Carries deoxygenated blood to right atrium

2

Pulmonary artery (top, middle left)

Carries deoxygenated blood to the lungs to collect oxygen

3

Pulmonary vein (top right)

Carries oxygenated blood from the lungs to left atrium

4

Aorta (top, middle right)

Carries oxygenated blood around body to respiring cells

5

Valves

Prevent blood flowing backwards

6

Septum (middle)

Middle of heart that separates left and right and stops oxygenated and deoxygenated blood mixing

7

Thick left ventricular wall (bottom right)

Pumps blood long distance around body

8

Thin right ventricular wall (bottom left)

Pumps blood short distance to lungs

9

Muscular ventricular walls

Pumps blood around body

10

Right atrium

Top left of heart

11

Left atrium

Top right of heart

12

Vena cava pumps deoxygenated blood to

Right atrium

13

Right atrium pumps blood to

Right ventricle when the atrial walls contract

14

The blood is pumped to the lungs via the

Pulmonary artery

15

Blood is oxygenated in lungs from gas exchange and returns to the

Left atrium via pulmonary vein

16

Blood is pumped to left ventricle when

Atrial walls contract

17

Blood is pumped to rest of body via

The aorta

18

Blood diffuses in the

Capillaries into cells for aerobic respiration
