Answer 1

1. a.

Pancreas is both endocrine and exocrine. Beta cells produce insulin. Left lobe is wider than right. Islets of Langerhans produce hormones related to glucose regulation.

2. b.

Left kidney is larger than right. Cortex is superficial and medulla is inner. Urine is formed in kidney.

3. b.

Pulmonary artery carries deoxygenated blood from ventricle to lungs for oxygenation.

4. d.

Small intestine consists of ileum, duodenum and jejunum. Large intestine consists of colon, caecum and rectum. Most of food digestion occurs in small intestine.
