Pleuritis

This artery is a continuation of the femoral artery behind the knee

Popliteal Artery

Deoxygenated blood is sent from the right ventricle to the lungs through this vessel

Pulmonary artery

The hole in the iris

Pupil

This carries blood to the kidneys

Renal artery

Two body systems that supply oxygen and eliminate carbon dioxide

Respiratory and circulatory

The photoreceptors are located in the nervous tunic which is also known as the

Retina

The two main channels of the lymphatic system are: the thoracic duct and

Right lymphatic duct

This main lymph channel collects lymph from the head, neck, mammary arrea and upper arm
